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.

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?

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.

Hi guys,
I just have an issue caused by me. When I've opened the phone I've managed to damage one of the components and that cause my vibration motor is not working anymore unfortunately as it is a part of the circuit for it. I'm just about to change it but the problem is I don't know what is the value of that component as I couldn't measure it as it was damaged so much so it wasn't possible to do so.
I would like to ask if is here any1 who can tell me what is the value of that SMD 0402 capacitor ( value in F = farad) - ( see the picture )?
Only problem is if some1 want to check the value it is mean that the capacitor have to be unsolder at 1st to do so. So please, if is here some1 who can do that for me I would really appreciate
Or maybe some1 have the BOM (bill of material) and schemes of HTC One X ? that would help too.
Cheers guys
DAMN! i doubt many people would want to do that mate, bit risky opening it!
Actualy to open the phone is not risky and it is pretty easy.Only thing is to unsolder the cap ad than solder it back that may be tricky and that would need a good SMT experienced person.
I just hope we have some1 like that here (except me lol )

If you get a multimeter and see whether the capacitor is across the power rails if thats the case then more likely it would be a decoupling capacitor that decouples the inductive spikes from the motor when running. I would take a guess that it would be in the order of nanoFarads maybe 100nF.
Even if this component is open circuited that wouldnt stop the motor from working are you sure you haven't put excessive force on the capacitor and it has subsequently levered up the flexible pcb and open circuited a feed i.e. track)from the controller chip that feeds the motor?
For such small work I have a handheld microscope with an inbuilt lcd screen. makes life easier
you need to look more closely in that particular area if theres a minute tear on a corner or 90 degree bend of the flexible mylar pcb
I have checked that under 8x magnifier and I couldn't see any other damage other than that crushed capacitor so I guess it is only that. But to be sure I will check it once again and I look closer on the whole circuit and all the paths
I can't check it at home as I don't have any equip here so I hope I will have some free time at work tomorrow
But thanks fro info, it may help

so I've checked the whole circuit for vibration and I haven't found any other fault than that damaged capacitor.
So it have to caused only by this for sure.
So I hope some1 can help me as HTC get back to me they can only repair in their repair center and they will not provide any details about any parts and they can't sell any parts either.
So as usual no help at all from HTC, grrrr...
Their customer service is one of the worst
So no luck at all with HTC customer service as I expected
1st HTC Reply
Thank you for contacting HTC regarding your
My name is Olga and I am a Technical Support Agent for the HTC Written Team.
I understand you are having problems with the vibration on your device and would like to know how much such component would cost.
I am very sorry this has happened and now you are having issues with your device, I have spoke to my supervisor about your query and can confirm that we do not have any rough prices of any of the components for our devices.
The reason for this is that we do not sell the components and use individual parts from different regions. The only thing we can do is book your handset in for repair with us. Please note that if you perform a repair yourself or use a 3rd party repair centre, your warranty with us would be void and in case the phone would need any future repairs, there will be a cost, even if it is a manufacturing fault.

Thank you for your email.
I am afraid we are not able to view online content, I can not view the links.
In regards to the components, we don't have any information regarding the components on our devices as this is something that is only available at the repair centre. Each device has a part number assigned, this lets the repair centre know which component and type exactly is needed for the repair.
I am sorry we are not able to provide further information regarding this as this is not something available for the public/customers. I have double checked this for you with my supervisor but I am afraid the only thing he advises is to have a look through the Internet for more information.

Have you a feed at the motor? Although if it sees the caps open circuit it may just stop the supply anyway.
That's a resistor isn't it? Not a cap.
I haven't tested the circuit with multimeter in any way but it is a capacitor for sure and not resistor.
SMD resistors have the metal contacts only from top-front-bottom side of the component
SMD capacitors have the metal contacts all way round
There are caps on that circuit, some are black and some grey color .
Only problem is that the caps don't have the value marked on the body as some resistors usually have, but normally bigger than 0402 package, so from 0603 and bigger as on the 0402 and 0201 would be really hard to read anyway

Might be worth getting a meter on it then, while setting it to permanently vibrate somehow.. Sure they're apps for that.
Unless your positive it is that cap, then id just pop it out and take a trip to maplins. I've soldered SM parts on phones before, it's fiddly but its possible. They were 50 quid Nokias mind, not 450 quid htcs. Fine iron, and don't get it to hot.
problem is I couldn't test it as the cap was cracked on half so no way to measure
There is no problem to solder/unsolder for me as I'm experience (work in Electronic manufacture business for some time )

If the SMD package is brown in color then it will be a capacitor. if black with no marking then may be a resistor or an inductor. if it is the latter then that would explain why the motor doesn't vibrate.

Surely you understand that HTC can and will not help customers with voiding the warranty of their phone? They support the devices as they are sold and if you decide to open and break the phone yourself you're basically on your own. Helping out with this issue would be to spend time and money to help a customer who has already agreed that no help will be given. Not to sound harsh, but you can't possibly expect any manufacturer to help out with such an issue?
Your best bet would be to contact a repair centre, not HTC. Regenersis, for example, might be able to tell you what component that is.
They only cost Like 50 p for that capacitor

Hi,
Did you manage to get your phone fixed, please give us an update mate.
well, not yet as I still haven't found what component is it.The HTC won't help as I posted before and I haven't found any1 who could.
But as someone mentioned here before that it may be a resistor instead of capacitor, so I've risk it and I just tried to shorten that pads and vibrator is working.
Problem is I still don't know what component should be there and I'm afraid that if I leave it with just a link between that may damage the whole circuit in time.
So it looks I have to live without vibration or send it for repair what I would have to pay for it.

My thread has been getting a lot of hits and HTC are monitoring it and possibly all my posts (I may be a little paranoid). Which I am grateful for as it is great to know that HTC are doing their best to fix the issue and I encourage them to follow my thread.
I will try forwarding this thread to Urban Strata (HTC Rep) and politely ask him if he can help. I will also try asking at HTC for you, I need to ring them next week on Tuesday anyway, maybe I can persuade them to help you, I did help make HTC aware of the WiFi issue and how many people where affected by it, maybe they can answer this thread to help us. I feel sorry for you mate and if I can do anything I will
Don't get your hopes up though and continue trying to find a solution yourself.
<EDIT> I've sent you a PM
Hi everybody,
(TL;DR at the bottom)
I would like to know what your experiences are with the following scenario:
I dropped my phone in a pond, left it to dry, did the rice thing, waited a whopping two weeks, very lightly scrubbed the reachable electrical contacts with a small tool to clean off dirt (did not cause damage to the connectors).
What I'm seeing now is quite strange:
Everything works, down to the compass, the gyro-stuff (I know, not a gyro but you get my drift), touchscreen, lighting, wifi, bluetooth, gps, the battery, the microSD card, basically everything you'd expect to break is working like a charm... except for the recognition of a SIM card. I can type the special commands in the dialer to obtain the test menu (and in doing so, using logcat, seeing no errors whatsoever while testing it, other than 'no sim card detected'), the phone still reports the same IMEI number, etc. It just says no SIM-card.
I tried to clean it up real nice on the inside (not the in-inside but the visible parts when you remove the antenna cover and battery cover) and saw no visible water damage even though it was completely submerged for well above 3 seconds. There was no visible residue as a typical drying process would normally show. I used a clean cloth and a host of very small tools to make sure I could clean all the small contacts and such. Remember, the SIM-card issue existed before the semi-more-than-thorough cleaning too.
I then proceeded to flash a new ROM, full wipe et al, formatted the sdcard just to be sure, I basically redid it as if someone would ask me to do it for them: in the most clean and surefire way possible. (no forgetting to full wipe, etc). I retested everything but came up with the very same issue. So I'm pretty sure it is hardware-related, I'm just not sure in which way.
Is it possible that I am looking at a physical deformation of some contacts which make the card 'not connected' when inserted? I saw a post in the forums about someone having the same issue, stating it was deemed to be the SIM slot being enlarged which was fixed using a small piece of paper, but I want to know if anybody has any experience with this kind of thing or happened to have come across the same situation.
For those of you with fewer time (aka TL;DR): phone dropped in water, dried it, cleaned it, booted it, all works except sim card detection, is that likely to be hw issue and if so any ideas?
Many thanks in advance for your opinions on this matter,
sstm

Seems to me that on a DHD there is an actual gap in the simcard cover & its the most likely place for water to enter the workings its extremely likely that the sim contacts were shorted & caused hardware damage.

When you say that the SIM contacts were shorted, can you tell me if there would be a solution for that, other than turning it in for repairs?
If the only thing I can do is turn it in for repairs I should change my question:
How much will this cost me? (on average) Am I looking at 50$ or more like 100$ or even more?
Kind regards,
sstm
Without a circuit diagram i would just be guessing which parts would need replacing & repairers will likely immediately turn away fluid damage as a non starter.
I think the phone is most likely not going to be financially viable as I'm fairly sure next stop after the sim holder is the mainboard.
Hi Pat,
Thanks for your reply, unfortunately for me, I believe it is in the line of what I was thinking too
Would it be a good idea to sell it for parts? Or maybe to sell the parts separately?
I never did that, but I'd like to at least get some money for this device, even if it isn't that much
Kind regards,
sstm
Well its a coincidence because i have a mother of 84yrs who has an old Nokia & no computer. She doesn't want a complex phone & likes her old Nokia push button phone but it has no sd memory.
But she asked me about a camera that she could take family pics & video & digitally store them. Something like your phone might be ideal.
A new main board is about $50. You could try replacing it yourself or have a reputable company replace it for you for about an additional $100 dollars maybe. Not sure exactly what someone will charge.

Here's the part you need on eBay.
Check out this item I found on eBay: http://pages.ebay.com/link/?nav=item.view&id=270946674338
It's a very easy repair. I had the same problem your experiencing about 18 months ago. I repaired it myself and my phone is still working fine. Just be careful not to damage the volume flex cable (part of the main board) when you take the back housing off. Also, when you remove the damaged sim/sd tray you have to pull forcefully (but carefully) as it is lightly glued on.
Don't be daunted, it really is an easy repair.
Good luck.

Hey guys! my name is chris, im a Mobile repair tech
I have my own company its 777 Mobile Specialists
So heres the problem i have, a customer has brought me a galaxy s3 t999 with the complaint that its not responding to touch anymore.
Initially i thought it was the Digitzer, and i told her the screen was a pretty expensive piece of hardware, so after some more testing, i put another logic board in with her screen and whaddya know? it works perfect, i tried multiple logic boards, all work with that screen, however hers does not.
Now with that being said, i did notice that there was some corrosion inside, it looks like some water had gotten into the phone, she speaks spanish and i dont so it was very hard to communicate with her in the beginning so i didnt get the actual cause of the damage.
Could you guys tell me possible what area of the board controls touch activeness and response? if need be i have many extra boards and i can take out what ever parts i need if found.
Thank you guys. ive been a member for a while but have just never posted much, but you guys are amazing, ive been using the roms here for quite a while and tutorials are awesome!
Thanks for reading!
It's been about a year since I worked on any GS3 internally, but if I remember correctly, you'll find the connector to the screen + digitizer on the lower left face of the screen off to the side. That should lead to the main board. If you look on ifixit, or even maybe YouTube, they have videos of GS3 disassembly that explains the components as they go along.
Sent from my SGH-T999 using XDA Premium HD app
Well actually i have it apart, and ive taken many apart, what i was basically asking is if anyone knows the actual location of the chip or resistor that controls the actual touch response to the digitizer, or even which pin on the connector is involved so that i can trace it back, because ive examined the board very thorougly and i dont see anything damaged or burned, but you know which these things, you cant tell that way most of the time, so i was going to do some multimeter tests and see what i get if i can locate the damn thing.
Anywho, thanks for your reply, but if anyone knows exactly what im looking for id be very grateful
Does the Teardown help ?
Damn, ive had no luck, the phone was water damaged, the LCD works perfectly fine wi th any other logic board and this logic board does the same exact thing with any other LCD, can anyone help
Anyone have any idea? Q.Q
Hi
Sorry for my english, I'm hungarian, this is the best I can do.
So I bought a cheap (but not too cheap) SM-P905, but I can't get the screen to work properly.
The touch layer, the spen, the backlight works well, I managed to mirror the screen on my pc and everything else seems to be okay.
I got off the back cover, I tried to unplug and reattach every flex cable, even the battery. I tried to look everything under magnifying glass to see what could be the problem.
The lcd flex connector looks like this under my lens.
(Upload it in the next post, not working from the android app)
I tried to clean it with a needle, but it still looks like it is corroded or melted.
Is it possible that replacing this connector will get the screen back to normal? (I found flex connector replacement on the internet)
Or is it possible to repair it with some jumpers or something like this?
Is it melted because of some shorted circuit somewhere else, or because of a bad micro capacitor?
How and where can I locate and resolve this problem (s)? Maybe is it still the lcd that is simply dead and I can't bring it back to life?
I dont want to buy a screen, and a motherboard (neither only one of them )
Thank you for your help!
Okay the forum doesnt let me to insert links or photos, because I'm new here -.-

In my opinion it died!!
I hoped for better opinions
I wanted to know how this thing can die?
It has to be caused by something.
Bad resistor/capacitor? Is it on the motherboard or on the lcd's circuitboard?? Or is it only the corroded flex connector??
I dont want to throw the whole tablet in the trash. Everything else is just operating fine.
If nobody can answer this, where should I write, where people can help with these very small components / resoldering / measuring what gone wrong here?

So today I measured the pins in worst condition. There are 2 pins that I tought can cause the problem and looks corroded. (Number 5 and 9 from the right) Both of them !are not used!. (There is a total of 3 pins that are not used on the connector/cable)
They are not lead through the flex cable, they have no function here.
So the problem comes from somewhere else, but I still don't know why they look like this.
Maybe I will try to seperate the screen from the body and look at it closer and its connectors/smaller circuit boards.

Hmm, that pic does not make me think its a corrosion problem. At best, it can lead to a finicky connection, but there seems to be enough there for proper electrical contact. If this were a headphone jack, for example, I would say apply pressure near the cable to see if the headset works properly, and if it does, then I know its a cable problem. No idea if you can try to apply pressure to the cable and see if the LCD turns on.
If the screen mirrors on the TV successfully, then there are a bunch of Samsung Service Codes you can use to test the LCD. Unfortunately I do not know them for this model, but google should get you the service menu very easily. There is definitely a test in there for the LCD that should give you a better idea what to expect.
If the cable is pretty cheap, I would also just pick up one and try replacing. Nothing to lose! AND if you have access to another identical device, you can try to stick this LCD on that device to see if its the LCD thats the problem or the motherboard.
Lastly, I would want to know if the glass on that LCD has ever been replaced. If they did a glass only replacement, its possible they overheated the LCD ... OR used too much LOCA glue that shorted the connectors.
Many possibilities, so I wouldn't call it a day yet. First, look for the service menu, thats the best place to begin.
I will try the service codes.
Unfortunately I don't have more devices. The easiest way would be to test the identical parts on a working one, but I don't know anyone who would risk his/her tablet for this
The other thing I can do is to get another lcd-glass unit from ebay or from ifixit and try it. If the problem was the lcd, it should work, I'm happy, but if its black, I will have (maybe) 2 working lcd units for sale. Or I have to get a new motherboard (sounds expansive).
I don't think that they replaced the glass on this device, it looks very used and scratchy, so it was working before.
Thank you for taking your time for me and answering my dumb questions!!
Sent from my SM-N9005 using XDA Free mobile app
There are more good news than bad, so I'm very happy.
So 1-2 days ago I started to get off the screen to see if I can seperate the LCD from the receiver. Turned out its not that hard. The only hard thing is to get it off the body in one piece. Lots of heating with a hair drier, and a LOT OF PATIENCE. If you can get it off in one piece you are on your way.
Seperating the glass from the LCD is very easy, did it in 10 minutes, I don't think it needs heating...
So I did it, then I saw some water damage (white things) on the back side of the LCD. There is a small board here too, so I cleaned the white thing off with some alcohol.
Then I put the lcd back and voilá, Its WORKING!!!
The only problem is that I damaged the touch screen glass, so I need to order a new one, but its under 20$ so no problem.
Thank you all for your help, I hope that I finished here
