Disconnected Ribbon

I was playing with my phone today, and all of a sudden the screen stopped working. I opened the keyboard and it lit up, and everything was good, but the screen was black. Rebooted, no good. I looked on the back of the phone, and right there was a disconnected ribbon. I have no idea how this ribbon got disconnected, but with my limited knowledge, I believe this ribbon is what connects the phone to the screen. I know the phone is working, I did a blind backup of my ROM, and when I booted normally for a few minutes, I felt a vibration from a text message. Is there anyway I can fix this? I already scheduled to go into the repair store tomorrow, but I kinda wanna do it now if anybody knows how I can fix it.
Also, I think it'd be smart to restore my phone back to stock, just in case they need to send it in for it to be replaced? I mean, I wouldn't want to find out they have to replace it, and then have to come home, restock it, and then go back on a different day just to wait 2-3 days for it to be replaced, or is it an in store job? (If so, can anybody direct me to a download link to a stock.tar? All of the links in the Thread with them all aren't working.)

Flashing to stock is always advisable when taking your phone in for repair - have you searched the forums for this problem already?
In my last repair issue...the screen was smashed and then four months later, the ribbon went bad, so they just junked my phone and gave me a new one since the screen was cracked. I actually hard bricked my phone instead of flashing to stock and wiped all data before that.

I recently got my ribbon cable issue fixed, it ripped because of a card sliding between the screen and keyboard. Originally they only replaced the top half of the phone for 35$ but the part they put on didn't work correctly. The speaker didn't work at all, so they ordered me a refurb it took a day and I didn't have to pay again. I hope they can fix your phone thoug.

Here's what happened. I took it into the store, and they told me that it was a hardware malfunction, and that they could not fix it. They told me had I purchased insurance, they would've fixed it, but it's not covered by my manufacturer's warranty. So now I'm stuck with no phone. I'm taking it into a 3rd party repair store to see if they can fix it, but until then, I'll probably have to order a new screen -__-.
EDIT: If I but a new Main Flex Cable, would I be able to replace it myself? Or would I need to replace the entire screen?
ALSO: If I take the phone apart and try to tighten the Main Flex Cable with some tape or something onto it, would that be possible?

wtf just happened to my phone's usb port?

just washed it off with a little soap and water and it went haywire. red LED came up. no water entered the port. moved connector around and LED went off. went to plug in and physically wouldn't connect to the charger. played around with it more and now it appears the connector is entirely damaged/not present. wtf? how can I get this replaced?

should have been more specific. i put a little bit of soap and water on the screen and the case, not on the sides or top/bottom of the phone.

Water/Soap (water in general) on a phone = bad period. wtf would you do that seriously??
As for getting it replaced walk into a store and just tell them it will no longer connect. but don't tell them what you did seriously. and never do that again.

indeed... strange that I cannot even physically insert the cable. anyway, got in touch with Sprint's chat line and the guy noted my account to walk in tomorrow and get a replacement. gotta love the service.

I don't have insurance. The phone is covered by a one-year warranty. The port failed to connect to a USB cable. see where I'm coming from?

Then you're out of luck. Someone walking into the store and saying "Care sent me here for a replacement" is an automatic defensive stance. We hate when customers say that.

If you haven't just gotten very lucky from sprint about replacement..two things one and it's weird but works..drop phone in dry rice overnight..it absorbs any water from phone..then make sure that moisture tags aren't on the phone by battery connector..no expert by any means but this website and it's members have saved my hide many many times with tips and tricks..hope this helps.

don't see how I'm out of luck. the failure of the USB port is directly attributable to a defect by the manufacturer. Sprint exchanges these devices and sends the defective units to Samsung(with a receipt, which I don't have, but the guy I spoke with said he could either have one for me in three days or note the account appropriately). everyone wins.

Clean phone...

No, you put a little bit of water on your screen and it created a short somewhere that effected the charging port. Let me guess ... you conveniently failed to tell the customer care Rep that you were cleaning the screen with water when the charging port stopped working.
Defect by the manufacturer? Seriously? Does anyone take personal responsibility for anything anymore?

Sorry. I had to fight through a little laughter. Obviously water is a big no no..... But, a few years ago I accidentally washed an old ipod left on my pants pocket. Took out of washer, put in a bowl of rice and covered with saran wrap. 2 days later was like new. Somehow the rice absorbs water even out of the tiniest places. Give it a shot, not much else to lose as of now right.
NV, just saw you sent it out.

I do hate to break it to you, but that isn't how it works. No customer service number, not even retention, has the authority to demand a technician give the customer a replacement device. The technician will inspect your device, probably trash the shoddy e-ticket created by care (although in violation of M&P to do so), and create a new one based on their decision. Can almost promise that you will be required to submit an Asurion claim

If nothing else, its good to learn/confirm from this thread that Sprint will tell you one thing, and completely do another once you deal with someone else, I have had this multiple times. So annoying ...

I'm sorry, but we don't honor manufacturer warranties. Unless you have TEP or even just ESRP, it will still cost $35. Provided, of course, that they don't find any liquid.

[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.

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?

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.

[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 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.

Screen replacement?

Hey guys,
So I actually upgraded from my G2 about a year ago because of a hardware issue with the phone. I basically developed problems with the screen and it turned out the problem was the power ribbon between the keyboard and screen. Luckily, I was able to salvage my data from the phone before I basically (and unintentionally) killed the screen by poking the power ribbon to try to fix the screen issue. So for the past year, it's kinda just sat in my desk and I just feel really bad about letting a perfectly good phone go to waste if I have the chance to fix it. Only problem is that is that I don't want to drop tons of money on an expensive screen replacement so I was wondering if someone could point me in the right direction with buying a replacement.
I don't want the cheapest option. I just want the best option (and preferably some instructions too!) for a screen and/or ribbon replacement and I'll gauge whether I want to restore my phone or not.
Thank you and kudos for those who are still using the phone! I miss it so much.

Can't really say how much it will cost where you live, but I find LCDs for about 20 and and flex cables around 30 where I live. Usually eBay is a good place to pick these up, being the flex sounds for sure bad I would start with buying that.
Instructions can be found with quick Google or YouTube searches
