[Q] Help! - DZ Repair Mission, Advice Needed.

My First Post! How's it going everybody! (Newb Alert)
I just purchased a Bell HTC Desire Z from a classified ad off of an older man who found that the phone wasn't fully functioning. The poor guy probably paid around $400CDN for the phone, but I ended up eventually buying it from him for $250.
Here is what is wrong with the phone:
1. Power Button-does not work, neither on or off...basically fully unfunctional and only way to turn phone off is battery pull...fun stuff! (planning on using the Teardown/Repair guide by verkion - recommended?)
2. The In-Call speaker (where you put your ear while talking on the phone) seems to have very limited sound, perhaps something has been destroyed on the inside, how all other sound mechanisms work, such as the external speaker and internal speaker w/ headphones. (planning on using the Teardown/Repair guide by verkion - recommended?)
3. The Digitizer, well parts of it (along the left edge of the phone when upright) are unresponsive, so called blind spots which when touched are unresponsive on the digital keyboard along with the home button (house shaped icon) - especially frustrating when browsing web pages because I have to click back like 10 times to get home... (planning on using the Teardown/Repair guide by verkion - recommended?)
4. It is a Bell branded phone, Locations does not work! however I have done the research on the forums and I think I can figure out the whole Rooting thing out, but advice is appreciated! (planning on using gtrab's FAQ for Dummies for the rooting, s-off, and de-branding)
Now...I am not really technologically inclined to the level most of you probably are, but I am good with my hands and really interested/curious about this whole mission I need to complete, so I can fix this phone myself instead of paying $100 for cell phone repair...plus its a nice challenge right?
Do you guys recommend that I take care, or at least attempt to fix the power button issue before I root the phone to a previous, unbranded firmware which will allow me to use Locations? This only makes sense right, because I am going to need the power button for that process?
I know this is a lot to ask, but I just need some pushes and shoves to get me on the right track to try and get this to work, so if it is technologically impossible or excessive...please let me know how I can fix 4 of these problems methodically in a safe and professional way!
Once again, I appreciate it.
Thanks in Advance
EDIT: My prediction is that the individual who originally owned this phone dropped it and as a result the digitizer, power button, and speaker were all affected...but of course I am no expert.

To me it sounds like the flex cable has been damaged. It would definitely cause all these things at once.
I'm pretty sure you need to fix the power button before rooting because you need the power button to actually root it.

Hmmm,
Never thought of that but it sure seems like a better diagnosis. The flex cable originates in the bottom half of the phone in the same compartment that the z hinge is found right?
It is also the flexible strip that runs through the middle of the phone when the hinge is half-way positioned, connecting the lcd/digitizer to the main motherboard of the phone?
I geuss replacing the flex cable would still involve the Teardown/Repair, however I dont think I will need to replace a power button, speaker, or digitizer IF!...that is the case.
Any other ideas on this?

Yes thats the flex cable, it is built into the pcb behind the lcd, so the whole pcb has to be replaced AFAIK. Yes it requires a full tear down to do it, fairly basic to do, my phone is in pieces atm because the lcd needs replacing.
If the flex cable is the problem then none of those parts need replacing, it would be very unlikely in my opinion for all those parts to fail from a drop without it being flex cable related, possible though.
Link to the teardown, some steps in the middle are unneccesary for what you need. http://tjworld.net/blog/htc-desire-z-tear-down

Hey, do you know where I can get a replacement pcb if I decide to take that route man? Seems hard to find that as a single part for sale...
I assume people replace their whole phone if they have a problem like mine :/

You wasted your freaking money on that phone!
250 is a huge waste!
You might as well add a line to your friends for the contract price.

it's not THAT bad...considering a brand new one unlocked DZ goes for 450+ and i knew I could fix parts of the phone so for -200 cheaper...i don't know bro!
I just need to know if a replacement pcb is possible to get, or maybe just the flex cable is damaged in which I wouldn't need to replace something so crucial.
Who knows what to do?
EDIT: 450 where I live...Ontario, CA.

...i dunno...could even be water damage that did the deed to that phone....in which case you could be replacing a pcb...or not....I've seen water-loged phones come back to life before....sad thing is it might cost you a few to fix it properly...
Totally agree 250 was to steep...that guy probably paid 79 on contract for it....

Wow about the whole coming back to life thing you just said...thats exactly what my digitizer just did, so the left side of my lcd is now working including the home button!
Im guessing the touch panel ribbon was loose but it somehow shifted to functionality.
Great...now for the in ear speaker and power button, and 250 wont seem too bad!
Edit: anyone know how I can look for past signs for water damage like a colored change in a sticker or something?

There are 2 water damaged indicator stickers, 1 under battery and, 1 under the back housing, you can see it through the opening where the top tab of the battery door latches.
Edit: Forgot.... 1 on the battery too.

What color would the stickers be? They are both white, does that mean anything?

If they are pink they got wet.

^^ What they said.... Pink or Red

250 is quite a bit for a device with issues, but good news is it isn't water damage by the sounds of it.
I'm an aviation electronic tech, and your symptoms definetly sound like a loose interface ribbon. If I were u id haul it apart and reseat the flex cable you guys are talking about. I would put a 85% chance that's the issue.
good luck, and welcome fellow canuck to xda and dz family
Sent from my HTC Vision using XDA Premium App

Sounds good guys.
However...even if it is probably the flex cable that is causing the remainder of my problems:
1. the in call speaker being super quiet
2. power button not working
Is there any other chance that the speaker and power button areas have loose connections? what should i look for when i open the phone aside from ribbon/flex cable connections?
I need to get the power button fixed because then i can move onto rom modifications and stuff to finally get locations!

[Q] DHD booting, but no display activity. How to repair?

Hi all. In need of a bit of advice here. Hope this is in the right forum.
My beloved DHD has suffered from one too many falls. Despite being protected in an Otterbox Commuter case, he now lies on his deathbed. Even though I was considering an upgrade, I'm thinking I might want to stretch out his life for as long as possible instead. So I've come here to ask for repair advice.
- The phone seems structurally sound from the outside, no damage besides minor aesthetic scratches from before the phone was protected by the Otterbox.
- It appears to boot. Makes the vibration noise etc. Heck the alarm even went off the other morning, at the set time of 0630.
- Screen does not function at all. Lifeless. But not broken in any way externally. Because of this, had to pull the battery to shut the alarm off.
- When plugged in to charge, charging light indicator does not illuminate.
Any ideas?

Cheers, although I'm gonna try a different approach for now.
Any ideas? Can anyone point me in the right direction of some advice?

Sounds like 2 things. Broken lcd and a broken charging port. It wouldn't be worth repairing. You could buy one second hand on ebay for aboot £120.
Sent from my nipple running windows 95 NT.

Thanks for that. Considering trying to sell it broken, for parts. Only thing that concerns me is any sensitive data that may be readily accessed by someone who knows how to get to it.
Is there a way to wipe it?

You could use another dhd with the same firmware and copy the key/button presses and reset it in bootloader mode.

Could also be that the connector for the screen has been dislodged due to being drop to many times you mite try opening it up and see if it is that.

Hi, thanks for the response. So I assume you're referring to this part here?
http://www.parts4repair.com/htc-desire-hd-lcd-screen-fpc-connector/
Seen in this disassembly video from the 3:05 minute mark?
http://www.youtube.com/watch?v=JfatoeWbMRk

bump...

I have a problem similar to yours. But in my case, I'd turned the phone off to go to the cinema and the LCD and touch never turned on again.
In order to erase your data, did you try overwriting a stock rom? (In case it's just the charging LED that is broken)

That sucks! Self detonating phone. Does yours still vibrate and 'turn on'?
Haven't actually managed to clear the data. I'm ordering this part here (http://www.parts4repair.com/htc-desire-hd-lcd-screen-fpc-connector/) and I'm going to attempt to pull it apart and fix it.
If I can get it to work again I'll sell the One V I'm using and go back to the old faithful!

Well this saves me from starting a new thread haha
Anyway i am having the exact same problem as you have.
My dad brought home a Desire HD from work wich was not working so i am trying to fix it.
The phone boots, it vibrates ones and after a minute it makes the boot sound.
But nothing responses and the lights wont turn on.
Also no charging light..
Also it does not charge but usb does connect.
Could this be the FPC connector or the screen?

Hmmm...interesting, exact same issue as mine.
Well, I've ordered the FPC connector replacement part I linked above...going to attempt to play around with it when it arrives and see if I can breathe new life into the phone. So I can tell you how that goes...
Although:
1. Would the charging light and screen problem be connected? Is this feasible? Or does it suggest something else is likely shot?
2. I believe the FPC connector requires a solder to replace. This could be a bit ambitious on my part to attempt to repair...any ideas on what sort of a solder would be suitable?

no clean flux core solder would work best, preferably something very thin (about .015"). A small bottle of noclean flux would also help and you probably will need lead free solder as that is likely what they used on the board to begin with, and lead and leadfree dont typically mix as well.

Thanks for the quick reply...
Something like this?
http://www.oritech.com.au/productDetail.aspx?productID=23244
What sort of iron would be suited? Would any of these suit?
http://www.oritech.com.au/categories.aspx?categoryID=321
Would you say it'd be a difficult process? I've soldered before, but a that was a while ago in high school...
Also the cost of all this equipment will far outweigh the cost of the $3 FPC connector spare!

yes, those should both work fine. ya it is costly for equipment. i have a edsyn iron i use at home and solder i get from work. i would say it can be tricky, i havent seen the connector but im sure its similar to other inline ribbon connectors. remember, short burst soldering, heating it for too long will take the pad off the pcb, and repairing THAT can become very difficult.

The Cause Of Screen Flickering With A "Possible Solution"

Many One X owners, including me, has be having from display/screen issues that are quite annoying. And apparently, none has a definite answer as to what the main cause is. hTC has exchanged all those faulty devices, claiming it's a "hardware" issue...while in fact, it's their stupid back covers...i'll explain as we speak.
First, to know what screen/display problem i'm talking about, please refer to this Video.
Few days ago, i got my hands on a "Dead" One X...but i just refused that fact...because it just works! but no screen....screen is always blank....can touch it, go to dealer and make a phone call even. Sometimes the screen turned, sometimes, and it was like in the video, exactly like it.....so what's the problem?!
yesterday, i'll be honest, i got mad at this phone and held it with a tight grip...my finger happened to press just above something...and the screen turned on! worked great in fact! i was astonished! it just worked....but, oops, i turned off screen, then when wanting to turn it back on...blank...
I kept pushing on the back casing of the phone, trying to find the same place that made the screen turn back on...and viola, same place pressed on, screen back on.
Wanna know what's causing all of this?
Here you go:
Click me!
And those connectors Should be in good contact with this on the back cover
Click me too!
But you know, hTC ****ed this one up, just like it does on most devices with connectors on the back cover...*sigh*...like the sensation for example...
So what to do now?
i tried a bunch of things, and almost broke those connectors with a stupid thick aluminum foil on top of them...
also i tried bending them up, but that doesn't help either, as when the cover pushes them down, their shape will change and well...didn't work.
i also tried putting aluminum foil on the metal connectors on the actual cover...didn't help as well!
it seems only pushing on it from outside does the trick!!
i also tried pushing on the connectors together while the back casing is off, didn't work...as it seems there must be a triple connection...board, connectors, and cover...
I think the only solution would be with a new back casing? but...if hTC f****d it up with this one, wouldn't all back casing suck too?? or is this a manufacturing problem that the connectors are just short and won't connect well?!
here are pictures of how the phone turned on magically after pressing over that connector, and another of how the screen gets messed up when the, well, there's not a good connection...Thank you hTC!
Sample 1 Sample 2
Tomorrow i will buy a new back casing and report if that helped me or not.
I only came to this because i have no warranty...if you have warranty, please consider an exchange!
Oh, and finally, i was able to get into bootloader, first time i saw that screen! always has been blank!...pushing on the connector also did the trick.
Finally!
Soooo...comments?
If anyone has an idea on how to make the back casing come in better contact with those connectors, please let me know.
UPDATE

Hmm, why did you put this into Q&A?

what? in a bad mood and wanna bash me?
where should i put it then? as people with such problem would come ask here, am i right?
EDIT: lol, it's all good now ^^

Well nah, would post it into General , as this was more like a guide. I wasn't bashing.. and not in a bad mood... If anything I bumped your thread up...
Also wanted to say that those contacts and that case seems to be f..cked up in general. As next to those you have the WIFI ones which in another thread, thats in General is shown how to fix...
My first comment was a compliment and you could clearly see I was smiling as I am on my avatar smiling. No reason to get defensive...

thanks ^^

Soldering would fix this!
putting two round solders on the gold plates of the back cover. i will try that tomorrow. but i fear they would squash the connectors on the board? as that's what happened when i used two tiny balls of aluminum foil....one connector got squashed by it and i had to push it back up and play with it to make it look normal again.....hmmmm

waw another fellow citizen
so before we go ahead and go
doooom gloooom htcccc suxxxxxxx
lets first affirm tons of people have no problems with their wifi and their screens
so yes those connectors issues whether screen or wifi are another forum of a manufacturing defect, things might not be perfectly aligned and hence the issue
the flickering issue your thread title suggests finding the source of, isnt related to this, 90% of the corruption we saw out of box on the HOX turned out to be software including the back-light flicker which HTC fixed by readjusting the LCD voltage
moving on to your question a new back cover might very well fix it unless the misalignment is on the board
but im wondering why is this pin related to the screen to begin with? the Sensation didn't have such a pin you could remove the back cover and the screen kept operating, also the disassemble photos that were posted for the HOX showed the board and screen running perfectly without the back cover
as for the stupid copper foil, make sure you don't loose it unless you are planning to make a bomb its added to distribute Tegra3 heat

Before you do that, please check the WIFI thread. There was already one member that described that soldering or adding a wire might be possibly harmful in the long run.
Changing the electricity stuff, how its called, the resistance or something (for the antenna though)

I'm having the same damn issue (check the picture) and thanks to Arabology for the well explanation on the problem. what I did was to send my phone to the service center and they told me it will take 3 working days (today was just the 1st day) for the technician to diagnose the fault and decide whether to replace the device or to repair it.
given that its a well known defect - should I just demand an exchange for a new device just incase if they revert that they repaired my phone? because I am sure the chances for the problem to reoccur is high.
Also just so you know I purchased this phone only about 3 months ago in HTC roadshow launch of OneX in Malaysia. HTC needs to come out with really quality products otherwise they will loose all their customers to samsung & apple (I believe they already lost major % of their loyal customers to their rivals)
oh well hope to get a good news soon. will keep u guys posted.

Update:
well, My One X is just cursed, few days ago it feel off my hand and the screen got cracked. now i'm waiting for my local repair station to get hold of a One X digitizer.
ALSO, HUGE NEWS, seems i was wrong. it's not the connectors. it's the whole part where there is a copper kinda sheath over it...i guess that's where are the cores are plus the Nvidia Tegra chip??! turned out, when i push there, that the screen lights up. at first i thought it's the connector, coz that's the most reasonable right?
what could be wrong under that? well, that place can be taken off, there's a metal housing that can be lifted off....idk, nothing seems wrong there...but seriously, just a slight push lights up the screen! so now i'm using the oldest trick in the book, i put a wrapped paper at the back of the casing, just where it will push over the place i talked about, and now screen is always on....just this small push does the job!! no more flickering!
i repeat, it's not the connector nor the back casing.......only God and hTC knows what's going on...
i did further investigations and tried to relate the "push" to any connections that could be on the board from the other side, but after disassembling the phone, there does't seem to be anything on the other side of the board that needs that certain force to help the screen to light up....idk, this just boggles the mind.
...anyone has any clue?!?
BTW, phone is working great even with the cracked screen, playing Dark Meadow just fine

i say you should demand an exchange. hopefully the device they'll give will be of a different tier of products that doesn't have that silly, unknown problem.
also, i'm pretty well sure that they won't repair your device. as i read many users regarding this issue, all of them got an exchange......seems pretty messed up. and i doubt my paper trick will hold long before this issue comes back

now that i have a paper inside my back casing, i can see that my WIFI connection is not at it's best, because of the extra space it took. so i'll most probably solder all the connectors

there was some guy, who posted a youtube video of when he pushed a certain area of his screen (the front part), it would switch off!
It only did it when pushed in that area, it was literally like a second power button.
Sorry I don't know exactly what it was, just the fact that somebody else had a similar problem!

HTC repaired my phone as the screen was faulty, it had a yellow tint, when i sent it for repair it did have screen flickering, ever since its come back, with a new screen, i rooted it and also put in the NEW ARHD rom, 2.05.2 base or something, it has stopped flickering :fingers-crossed:

Finally found someone with the exact same problem. I haven't been able to use my hox properly for weeks. Think I need to be sending back to HTC
Sent from my X10i using XDA

Finally I've got my OneX replaced with a new unit.:laugh: Hoping this will not have any sort of hardware faulty anymore.
interestingly. while waiting for my turn in the service center, I was just talking to a guy sitting and waiting beside me who came to report a problem with his OneX
and apparently its his 4th time visit to the service center. And all his previous 3 visits ended up with his OneX getting replaced each time....and each time with a different hardware issue (screen flickering / dead pixels / color faulty). Oh man....I thought the OneX was the best quality product from HTC.
and now I'm having a slight regret that I shud have just waited for another 2 more months and bought the SIII instead. God knows what other problems my OneX is going to come up with.

what could be wrong under that? well, that place can be taken off, there's a metal housing that can be lifted off....idk, nothing seems wrong there...but seriously, just a slight push lights up the screen! so now i'm using the oldest trick in the book, i put a wrapped paper at the back of the casing, just where it will push over the place i talked about, and now screen is always on....just this small push does the job!! no more flickering!
i repeat, it's not the connector nor the back casing.......only God and hTC knows what's going on...
i did further investigations and tried to relate the "push" to any connections that could be on the board from the other side, but after disassembling the phone, there does't seem to be anything on the other side of the board that needs that certain force to help the screen to light up....idk, this just boggles the mind.
...anyone has any clue?!?
BTW, phone is working great even with the cracked screen, playing Dark Meadow just fine

Probably what's referred to as a dry joint or some other connection not connecting very well, not uncommon in electronics.
You need to get it repaired or replaced, simple as that. If it is a dry joint under one of the chips that use a ball grid array of solder points, you will never be able to sort that out yourself and it would be scrapped more than likely rather than a repair attempted for such a fault. To repair, it would need to go into a special over to heat it enough to melt the solder under the chip. Exerting pressure will just eventually make things worse as you can end up fracturing more of the soldered connections as there is little give to resist flexing.

[Q] My glide is screwed after wifi download overnight

Hola, noob here with a problem.
My rogers captivate glide was behaving perfectly fine one night when I decided to download some large files over wifi. It was also plugged in for charging and I was using some app (forgot the name) to prevent my screen from turning off so I won't lose my wifi connection. I left it like that and went to sleep. Upon waking up, my phone was hotttt , the screen still on but it has faded into a greenish color with scan lines. It was unresponsive and I had to pull the battery. Ever since then, my phone would last no more than a few minutes before freezing and fading into scan lines. I thought it was a battery issue, so I got new batteries but that didn't help one bit. I even flashed the kernel and still no help. I did resets, recovery, wiped caches, took out sd card and sims, stock builts. Nothing worked. I can't connect the phone to the computer or wall charger either. The screen would instantly freeze and fades out upon plugging in the micro usb cord.
Have anyone had similar problems? Did I fried the soc? I don't think it's a problem with the screen since it was perfectly responsive the few minutes it worked. This noob needs helppp.
I've posted a video on youtube but I couldn't link to it, but if you search "captivate glide problem" you'll see a video showing the freezing problem I have. I'm from the US also, so I don't know if I could get samsung to fix it through warranty since the phone is Canadian.

Well I downloaded Modern Combat 3 and that was like about 1Gb and the screen turn off because I didn't touch it while it downloaded, and wifi kept going so I'm not sure why it didn't stay on for you

Idk about the phone so much , but i am computer technician and it sounds like you overheated it, what we might call "burned it up".
The screen symptoms you have described are a dead giveaway, especially the lines
If this was a laptop, I would be sending it off for a reflow .
Typically, the circuit board gets so hot, the solder on the ships melts enough for a tiny bit of separation. This requires a "reflow ", where specialized equipment is used to repair the solder connections.
First, you should to a factory reset , then try to do a warranty claim. (unless u have insurance from your cellular provider, then u might check with that)
*edit, sorry, I missed the warranty part the first time I read ur post*
The next option would be to check with the guys at www.mylaptopisbroke.com
Email them, ask if they concur with my diagnosis and if they can help.
I have been dealing with them for about two years and always been highly satisfied. (They are in NY, I am in TN. I have sent literally dozens of devices to them)
If none of those 3 options work out for you, start looking for a new phone.
Sorry :-/

Sorry, but I agree with the previous poster, sounds like a hardware issue. Start the warranty process, can't know if it's gonna work til you try it.
Not to try to close the barn door after the horses have bolted, but in case you get into a similar situation with your new phone, there's an easier and safer way. When you're in the WiFi screen hit the menu button and under advanced settings there is the option to keep WiFi on during sleep. Also, as you have found out, be careful with any apps that directly control the hardware.

Had a very similar scenario as the OP described. Went to bed with it plugged in and streaming DI FM in high quality, woke up in the middle of the night by burning myself on the metal back plate. Unplugged it and pulled the battery, when I woke up in the morning after a rather worrisome night sleep I discovered my WIFI would not work unless I was within a foot of the router otherwise it wouldn't get any signal. I assumed the devices internals were damaged and that is what caused the problem, glad to know someone else aside from me has had a similar issue. Best bet would be trying to get a replacement through the warranty unless you have some type of protection plan through your carrier.

I see, thanks guys for the inputs. I had a feeling it's a goner. I can't do the warranty since it's rogers and I'm from the U.S.; bought it off Newegg unlocked without a warranty. So I guess I'm screwed.

Had the same thing happened to me. Had to send it to sammy to get fixed the had to replace the whole board

I've contacted mylaptopisbroke and they told me that phone repairs have been discontinued until midwinter 2013.
Is there anywhere I could buy a new soc??

Try mobiletechvideos.com or phonedoctors.com

I've heard of reflowing oneself by putting it in the oven at 550 degrees for 10 minutes or something. FWIW.
Not sure I'd want to do it myself, not having better information, but perhaps there's something out there some googling will reveal.

I've look at the sites, no captivate glide stuff. Guess captivate glide is not that popular a model. I've read about reflowing, but too chicken to try. I did took took the phone apart but saw that the LED is on the board itself and couldn't be detached; it's housed in some soft rubber feely box. I had a feeling it would melt in the oven.

in the options you can change it to keep wifi on all the time.. i keep mine on all day.

Yeah... I know that now... too late though.. ahah

What have you done with this?
Have you turned it on recently and found it still works?
I have a similar problem and other threads have suggested it's a software problem that might be fixed by installing a new ROM via odin

Has anyone sent their M8 for repair?

Ok, what happened here is my phone went to swim with me crying.
I tried to dry up the phone, but I still can't turn it on. Then, I send my phone via my carrier (Rogers Canada in my case) for repair. Of course, I am pretending to be innocent saying I don't know what happened to my phone, and I just can't turn it on. Then HTC (I suppose it is some outsourced place, but should be licensed under HTC) told me that there are COLLISION on the mother board and somewhere else, which is ridiculous. There is one much more ridiculous thing: the repair is going to cost
$1000
Of course, I am not asking them to repair for me. I just want to share how ridiculous it is, and if you guys can gimme some hints on how I can have it repaired, that will be great.

your phone CANT be repaired. It got wet. end of story.
what you need is a new phone.
I bet he meant corrosion on the main board. Also i personally dont like to read posts where people know they got the phone wet then try to play dumb and pull one over on someone or a company. That shows very little integrity on your part. But i dont want to turn this into a personal attack as the mods dont like it. SO lets hope a mod reads this thread and shuts it down.

If you're lucky the phone might magically just turn on, on any given day. I've seen that happen

I accept your comment, but what I wanna say is $1000 is ridiculous...

I will agree with you there, 1000 bucks to fix a phone is way overboard. Unless theres some conversion were missing. like 400 USD = 1000 what ever lol

It's 1000 CAD, which equals around 930 USD.

This doesn't even sound right. How can the repair cost more than the actual cost of the device. I'd look for another repair option.

Diagnostics, manual assembly, etc. Very little can be reliably salvaged from a water damaged phone. Assume everything but the case needs replacing. It's what's known as a write-off.

I've washed them full cycle several times. Each time when I found my phone i soaked them in alcohol and agitated them for about 20 minutes fully submerged. Then I use a toaster oven and dried them out with gentle heat and by sucking air into the phone about 20 times. All of them worked again. Even an iPhone once. Yes, I said full cycle. I found my phone in the when I was loading the dryer. Have I been lucky? I dunno. Many find this hard to believe, but it's true. I put a charging port in my girlfriends note 2. It came from a water damaged Note 2. It was sitting in parts for 2 months. I figured it was dry because it was sitting in open air. Well I put it in and it worked. A week later she lost data and voice. Long story short, that chargign port wrecked everything in the Note 2. When they opened it up, it has white fungus looking corrosion working halfway up the phone in three spots. It absolutely ruined the Note 2 and an insurance claim had to be made. It can go ether way, saved or junked. Just depends on the conditions.

Wow, I guess you don't learn fast.
Water damaged vs got wet.
If you're quick enough and use the correct method and lucky, you may get the thing working again, but I'd hardly say reliably. HTC or any repair centre are hardly going to want to provide a 3 month warranty on a repair of a phone that's got wet without replacing everything that can be damaged by water.

The sum of the parts is greater then the price of the item.
Thats why we have chop shops. Some cars are worth more when parted out and the pieces are sold individually.
So if each component was being sold to him at retail pricing, add labor and whola, higher price.
