Hey guys!
Yesterday, I tried to fix a HTC desire which had a broken digitizer. I bought a new digitizer and followed the instructions here :http://forum.xda-developers.com/showthread.php?t=1566313
After I assembled the phone again, I felt the vibration when I turned on the phone, but the screen didn't turn on. The buttons were lightning up as well so I guess everything is fine, but the LCD.
I think I did everything good during the assembly, and I even tried to do it like 4 times, but everything is the same. What can be the problem? Did I screw up the LCD?
Should I try to buy an Amoled for the desire and put it in?
Thank you in advance!
What screen did your desire have before? If it was an Amoled, then you should have bought an Amoled replacement, not a lcd one.

I have 2 droid incredibles. The first has water damage to the motherboard so i purchased a broken one online. after i had switched out the touch digitizer and the lcd(the working one is amoled) and put it on the good motherboard the phone will vibrate once and will not boot. using the cracked screen the phone came with it will boot all the way(i can hear it say droid). I am sure all the connections are good. I'm pretty sure both phones are the amoled model. the one i bought broken is an adr6300vw(original) and the water damaged one i have is an adr6300vw2(also amoled) the only thing i can think of is that the broken lcd phone was flashed back to stock using an ruu and was flashed for the slcd and not the amoled. if thats a possibility. if anyone has any insight or suggestions please help.
thanks in advance.
Had the same problem
I had one each, an incredible with a cracked LCD and an incredible with a cracked digitizer. Took the digitizer off of one, and replaced it, but put the wrong motherboard in. My edumicated guess is that the mother boards are programmed to a specific LCD screen and won't work apart from each other.
Hello everyone,
I know there's a lot of threads about broken screens out there but I could not find a precise answer to my question.
This is what happened. My HTC Desire (with AMOLED) fell on the ground. When I picked it up I noticed a crack. It seemed like it was not on the touchscreen but underneath it. Also, in the first hours the display worked well like always despite the crack. Then, the next morning, I woke up to a surprise. The screen was now loosing it's colors and everything was in a kind of violet range. The next day, the screen was completely black (but I could feel that the touchscreen was still working because of the small vibration during unlocking).
Of course, the "official" screen replacement is too expensive for me and I think I can do it myself. The problem is that I can not find a site that's selling AMOLED screens for HTC Desire, only LCD. So there's my question : is it possible to replace an AMOLED screen with a LCD screen (on the HTC Desire)? Or maybe someone knows a site that's selling AMOLED screens for HTC Desire?
Thank you in advance.
Switching screen for screen won't work. At least you would need to replace the digitizer too, and I'm not sure will it work with your motherboard. Total cost of screen + digitizer would be around $110.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
I know people mentioned different digitizer for different screens. I'm not sure that's true but a different motherboard would be required.

eek:ne friend of mine ask me for help: Her Desire S Screen was broken, so she sent the phone to a repaire shop, however, the boss just ask her to replace not only the LCD but also Digitizer, the boss siad if the Desire S Lcd were broken, the LCD and Digitizer must be replaced togerther.
So, it is really a bad idea, i don't know if we can only replace the LCD? not both of them togerther?

As far as I know replacing both is not required. Recently my desire fell down and had a crack on the screen. Touch drivers were working but the display had gone kaput. I got the display replaced at the authorized HTC service centre in 30min. Its been working flawlessly since then. :victory:

Dear Omcho, thanks for your advice.
Ok, so the phone turns on, LCD screen even flickers on once in a while, it won't stay on though. And everything looks just how I left it. So I'm assuming the mother board is good, the LCD is bad/fried and the digitizer glass is ok. Would that be a safe assumption?
Now, I had two other Incredibles, one with a cracked LCD, one with a cracked digitizer. Swapped out the digitizer and as long as we put the right mother board in that went with the LCD, it worked great. So I'm assuming I can't just go buy an incredible off ebay with a cracked digitizer and swap out LCD screens? And will a "New" LCD replacement screen work? Thanks!

I don't see why another LCD screen wouldn't work, but it's really hard to say with this kind of thing without just trying it, which is what people want to avoid because throwing parts at it costs money. Its not necessarily true that the motherboard on the device is ok. Its certainly possible that it could be fried, but in a way that allows power to still get to the LCD but not control it properly. Another option would be, since you will be taking it apart anyway, inspect the motherboard or other circuitry if you can see it and look for burn marks on the board that would indicate a short circuit. You can't always see them, but it would tell you if it were bad if you can see it.
Hi guys, I just replaced the LCD in my old desire z. In the previous screen, I dropped the phone and from then on the screen wouldn't turn on. So now I've replaced the lcd but it is just the same. The screen doesn't power up. The digitizer seems to be working with the capacitive buttons lighting up. I am assuming that something else seems to have been damaged in the fall. Probably not worth the money and time to figure it out and fix it?

That would be hard to rule out unless someone can test that LCD you are changing with does not have any problem. Another question is that which instructions did you use to change your LCD ? Once I mistakenly stood over my Desire Z which was only few months old then, LCD cracked at that time.
I bought LCD from the following seller on eBay (i checked today and he do not have HTC Desire Z LCD any more)
(Sorry i am not allowed to add URL, if you PM me i can send you details)
In terms of instructions, the only video available in those days was youtube. com/watch?v=Us-28oXfIbg&list=PL604790BEFD39AE09
Now this guy has few other videos on HTC Desire Z.
From the posts of this guy, it appears he now opened up shop for parts and repairs. See if he could help. Nothing wrong with emailing him.

I have pages of htc desire z lcd on ebay.ca...
The problem is probably the flex cable.
Most of the time, lcd screen show signs of weakness : fliker, dead pixels, color lines, shot off after few seconds, etc
