Desire camera module replacement due to hw issue - Desire General

Hello guys,
I thought i might share with u my pain. The camera on my desire is not working, it shows only black screen whenever i launch it. Downgrading to 2.1 stock didnt help. Didnt work either in the ota 2.2 rooted rom. By matter of exlusion the only thing left is hw issue. Therefore, as i have no warranty, in a desperate attempt to fix it i bought a camera module on ebay. I am not sure that the problem is in the module exactly, but anyway there is no way to isolate it perfectly. So i saw an official htc video for disassembling (looks quite scary ). My question is - does anyone have experience with replacing parts? Any suggestions are highly appreciated.

just done it today with mine had same problem black screen on camera , only advice is to take your time and be gentle as its pretty straight forward.

I have to regretfully annoumce that after replacing the camera i still have the same black screen in both android froyo and gb custom roms. However when i was replacing it, i saw quite a lot of oxidized metal on the pins inside the camera slot. Tried to clean them but definitely did not do a good job. I am the second owner of the phone so i have no idea if it was water damaged.... But its definitely very strange to find it there.. so probably there is lack of good contact. Any idea about a safe way to clean the pins?

ok, just a short update and conclusion:
after some googling I decided I will try to clean the pins up with rubber and a needle. First scratch with the rubber, after that with the needle (to remove the oxidized surface). However as the pins are very very very fragile :-D (and the fact that they were heavily oxidized definitely helped), 6 of them just fall even by the softest touch by rubber/needle (believe me, after the first one fell I became even more careful). So, after that I spent approximately 5 hours replacing the broken pins with wire from an old audiocable that I had around.
To my "surprise", when I turned the phone on the camera still showed the same old black screen. At this point I gave up and declared that I will not have camera on my desire
So, anyone interested in buying a brand new camera module for desire? :-D

HTC Desire camera module
Hi there sorry to bring back a old post but searched high and low and this seemed the best place to ask how does the Camera module fit to the board is it cable or are the pins u mentioned soldered onto the board any help with this would be much appreciated before i go in and rip this handset apart to try replace the camera module Thanks in advance for any help offered

I had this problem after I had the screen replaced, which I cracked. The technician damaged the flex cable while he was working on it. Luckily he admitted his error when he checked it and replaced it. So maybe it is the flex cable.

Can't help with they one. Sorry mate.

LCD color problem: Weird Teal/Blue-ish

Hey Everyone,
My LCD screen seems to not be displaying colors as well as it should, almost as if it isn't displaying all the colors that it is in fact capable of...
I had some prior problems with my phone, including a non-functional power button, a digitizer with some unresponsive blind spots along the left and right side of the screen, and a very faint/low volume through the in-call speaker.
I had been planning to go inside my phone using the teardown/repair guide, and actually ended up stripping my phone down to the LCD panel.
The good news is I have fixed all the problems that I had set out to fix while doing the teardown.
HOWEVER, my screen is now a weird teal/blue color. For example, when I equip the standard HTC skin (the one with the nice colorful bubble background) Instead of the notification bar/button being a solid steel gray, they seem to have striping pattern with some dull colors of gray but with this teal coloration.
I was wondering if it is more likely something to do with the pcb/lcd getting slightly damaged when I did the teardown, or is it possible it is something to do with a setting on my phone? (the boot screen did load up once, when I was doing the teardown and checking if my phone still worked, I chose reboot as the option)
HELP!
Well more then likely it is the conectors I've seen it to many times when people dicide to take apart phones id say take it all apart and make sure your cabbles are plugged in nice and and firm report back and tell me. Also make sure you havnt nicked anythng on the pcb boards (traces or anything) no nicked cords ect

Same thing happening with mine, it's a week old and I've never taken it apart.
Only thing i can think of that happened that makes sense is a damaged pcb flex cable, thats it.but the weird thing is i fixed everything else. Its annoying cause videos look wack and taking photos is also messed. Ill probably go back into my phone and see what i can do, ive opened it like 8 times so wont be too hard.

Just wonderening if anyone found a solution to this problem as I am experiencing the same thing. I have never taken my phone apart. I have my own post called display color problems. Please help! This is absolutely obnoxious!
I sent mine back to Bell for repair. Took 2 weeks, don't know what they did but it works great now.
Was that an expensive repair? Wish I knew what the problem was so I could try to fix it myself.

Is your phone not under warranty? If it's because you rooted it, you can relock the phone with gfree and restore the BellMobility RUU...
Yeah I guess I could but I really can't go two weeks with no phone. That's the main problem.

Figured I'd give this thread a bump. Really just hoping that someone out there has some experience with this problem. I've searched the net high and low to no avail. I don't want to waste money on unnecessary parts if I just need one. Presently, I plan on replacing my LCD. If anyone has any other suggestions, I'd love to hear them...
Sent from my HTC Vision using XDA App
This happened to me before i first opened up my phone. I wouldn't replace the LCD because i cracked mine, and had to replace it and it still does it. Just try and get a replacement phone from your carrier or the store from which you bought it while they fix it. Easiest option.

[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?

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] htc one x problems after screen repair

hi, have searched and searched on the forum but no real answer to my problem.
i dropped my htc one x and the glass cracked, so i sent it away to a supposed reputable firm (i didnt realise htc repaired phones aswell otherwise i would have sent it there)
anyway the lcd display and brightness worked perfectly, the company have replaced the screen and now the backlight no longer works and flickers when touched or cpu is being used.
they have said it is the display IC, and coil etc,
they say that this was caused by the phone being dropped, and not by them and they have charged me (they take payment before sending phone back), they initially took the phone back, and 3 weeks later they have decided to wash there hands of it, have put the phone back together shodily tell me i have to put up with the phone as it is, and refuse me a refund.
they acknowledge that the ic was fine before they took it apart, but blame it on the nature of the phone design as to why it now doesn't work.
i would post link to another forum explainingg the possible issue (has no explanation of cause though) and pics of the phone has been returned to me, but i can't because im a noob
Basicly the question is,
Who is at fault?
And how could the ic get shorted out,
The backlight flickering is likely to be poor installation of the new screen.
Again this is an old example I'm referring to here. I used to replace the screens on the Nokia n95 quite regularly.
You get the screen assembly and the ribbon cable which attached to the motherboard.
If the ribbon cable was not seated 100% perfectly I would get the exact same symptoms you are describing.
No backlight. Pressing down on the screen would either get it to flicker or come on for a while.
It shows a poor connection. I took the screen back out and repositioned the cable back in. Reassembled and then it was fine after

Phantom digitizer problem.

Well after owning my HTC One X for a year I noticed that I'm having a problem with the digitizer (touchscreen). On the lower quadrant of the screen there is a rectangular (invisible spot) where the digitizer doesn't work properly. Sometimes causes the screen/keyboard/unlock all by itself. Aka the Phantom digitizer. When the digitizer is acting up I can't activate any part of the touchscreen in that area either.
Although this problem doesn't happen all the time. Just periodically through the day and some days more than others.
I think it's because of a dirty power supply to the digitizer that causes this problem. You may have seen other threads of people plugging in there phone and not being able to use the touch screen. This is also due to a dirty power supply.
Example: when I plug my phone into the wall at work (which I know is a dirty power supply) it creates the exact same problem.
Could the voltages/battery/power supply cause these problems with the digitizer?
I'm looking to fix this without spending money on a new screen.
Edit 1
Possible causes:
Battery Connection issues
death grip (I have wi-fi issues) - testing now
Voltage issues - unlikely the problem now
dirty power supply
more if i can actually get some help
This is also similar to the One S button problem
Edit 2
Currently flashing 100% stock rom.

I know that's caused by a dirty power source. Sometimes old buildings outlets and crappy wall chargers cause this. My problem is even on battery. I think I either have a bad connection on the ribbon connection for the digitizer or a defective digitizer overall.

Yes it was the digitizer and I figured out the problem as well! The polycarbonate unibody is very flexable and over time when you stick your phone in your pocket, sit on it by accident, hold it too tightly etc. etc... Th polycarbonate and the gorilla glass flexes that could cause damaging the digitizer. Another problem is that it gets worse over time so some type of connection loss.
A new digitizer fixed the problem and it still works to this day. My friend bought it from me after I did the repair myself and put a new polycarbonate body on it. Decided to go with the black color this time. If your going to do the repair yourself try and remove the old digitizer from the LCD BEFORE your buy your parts. This is because you are likely to damage the LCD like I did so I bought the LCD and digitizer together making the installation much easier.
My new polycarbonate body is much more stiff too so hopefully the problem doesn't happen again and no more scratches on the device. Sold it for $450 and only paid $100 for the parts on ebay.

Thanks a lot Tw1tchy.
Indeed, this should be some sort of a connection problem because in some positions my phone has a higher chance of reaction than at others.
What is also curious is that this stuff started happening to me after latest ROM update (I'm on stock). I recall that the phone became really hot during the update and suspect that some sort of glue melting happened but I am no engineer so I'm going to a repair center tomorrow. Hopefully they can figure out what is causing the connection loss; if a replacement is needed I will probably have to pay $200 for everything
Sigh. This phone brought me so much unhappiness with HTC I already made a decision that this was my last HTC phone, next one is going to be new Nexus. Used to really like the company when I was using the Incredible S..

So I took it to a repair center. What is curious, they said it is not a digitizer problem at all. They say it's a factory fault and willingly made the issue appear by pressing some certain part of screen.
Now I don't know what to do - sell it and buy something new or do the repair (the cost is approximately the same).

Black screen, only backlight works. Everything else is ok.

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!!

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
