Desire camera module replacement due to hw issue

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.

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.

If you decide to sell off the motherboard, let me know. My One X has a dead motherboard.

[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

Hi mate did you managed to get this sorted I am having the exact trouble same issue with a company call Elite Phones and Computers.
They are saying that the IC shorted out and the only repair would have to be a replacement board.

had the same ..from now ill always send it to htc if something is broken again it costs the same i found out

any chance to find schematics of the pcb?

Hi guys, i have an issue...my phone dropped in water...everything is working fine (i swapped components with another phone) but not the charging part...battery is good...
disassembled the phone, in the pcb under the metallic plate there is a burned component...i have a friend that can replace it but i need the schematics of the motherboard to choose the right component (voltage, power ...)...i can't find online a schematic of the motherboard, can you guys help me ?
the problem is that phone won't charge, it gets power (with tester i can see it) but phone olny turns on for a second and then shutdown...i think the component is a power regulator or something like that
ps. sorry for bad english

Since you dropped it into water it's big chance that much more parts are screewed. I suggest you to disassemble phone and look to motherboard an electric parts are they rusty, rust will be white color if there is a lot of that than you shouldn't fix that part because a lot of stuff is broken or will break soon. You can try placing phone in supersonic bathtub but that won't help for long time in most cases. If your friend can replace part than he should know how to find that part if he have knoweledge in that area.

don't worry, the other parts work good...i swapped all parts (lcd, speaker, touch and more) with another motherboard and everything working fine...after i dropped in the water i cleaned the phone without turning on from everything...the only damaged part is that chip (burned) under the metallic plate...the rest is clean as new and working...if i can identify that chip (o what the hell is it) a friend of mine can replace it

Well, I doubt you will find scheme anywhere online. What you can do is to post picture of that part which is broken/burned and post picture to some forum for electronics maybe someone will recognize it.

Hey, is this (https://goo.gl/qMGcmV) what you're looking for?

i don't have the phone right now, i asked my friend for a picture but still no answer

thank you but no...i'm looking for the schematics of the motherboard...i'm putting a picture of the damaged component

What can happen ?

Note 5 pro got splashed by water and without knowing it, I charged it.
It got fried.
I went to service centre.
They replaced the bottom board which contains the charging port.
Now my phone is working.
But all my sensors got fried, it not working.
Since, all sensors come with mother board,
I can't replace sensors. I should replace the motherboard for resolving.
Can my motherboard withstand for long time ?
Do the fried sensors can damage the motherboard in future ?
