Phone won't boot with new screen

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.

Problem with my Wildfire display [help please]

I have dropped my Wildfire on the floor and after i picked it up i had a spot on the screen(you can see it in the pics attached).I want to order the parts necesary from ebay because i saw they have good prices.
Please help me because i need to know..what part do i have to change to get that spot away from the screen?(the digitizer,the display?)
Thanks!
PS: the touchsreen works perfectly

really no one knows?

asking again..please help

I had exactly the same problem. That mark you see on the screen is due to dead pixels. I dropped mine too and I had a spot just like yours. Here is how I solved the problem.
1. Go to ebay and buy an LCD screen for wildfire. I got mine for less than $50. You just need the LCD not the touchscreen digitizer. I think you can get it cheaper.
2 Replace the LCD. I could not find a dissassembly guide for wildfire, but you can follow the Desire guide. They are pretty much the same. I am talking about the steps. Obviously, they different phones.
Since your touchscreen works, it is easier to replace the LCD.
Now my wildfire works fine with a working LCD.
Good luck

If the touchscreen is working without any problems then it is just the LCD Screen you need, It is a separate part from the touchscreen.
Where i used to work, the sales team used to rip people off by telling them that the touchscreen and LCD screen came together, but most of the time they don't and can be fitted separately, sometimes however they are together and need to be bought together. I have been inside one of my own wildfires to fit a new touchscreen it didn't go very well but it works......... minus the LED lights and i can tell you the LCD screen can be purchased and fitted separately.

Dude of course it is up to you wheyher you wait or not,
But i am telling you, i had the exactly same issue... My phone fell to the floor and i had the spot on the pictures you posted. It is because of the dead/stuck pixels on your lcd. My touchscreen worked fine too. Just replace the lcd and you are in bussiness.
And I agree with the poster above.

thanks allot guys
i saw some wildfire lcds at 15$ on eby so i think ill order one right away

dead pixels arent good but what about my dead "lines" ? it looks like the HTC is censuring everything i want to read

OMG!!! Look at this thread - screen replacement ;)

Hi, I'm wanting to replace my HOXs screen.
There are yellow spots on the screen, does this mean I need to replace the lcd panel as well or if I just replace the glass/digitizer will this fix the yellow spots?
Also, I managed to fix a galaxy ace screen (glass/digitizer) by separating the digitizer from the lcd panel and the lcd panel is fine. I know it has been said it's not really possible to separate the two with the HOX but if I have managed to do it for the ace, do you think it's possible for the HOX??
Any thoughts would be appreciated

You don't really need to replace the screen if you have orange spots ,just put the screen on full brightness over night and your problems will be solved , if you want to replace the screen ,replace the whole thing as you said I have seen only one video out of 60 that the guy was successful in ceperating digitiser from LCD ,good luck

They will disapear after some time. I had the spots too.

Thanks for the replies.
Sorry I forgot to mention that the screen is cracked too. But my main concern was separating the lcd from the digitizer. I did do it for the ace and it was pretty easy buy if you think I would be better off to replace the panel and digitizer, then I'll do that.

The things is, the ace and the hox are very different devices. Just because you've managed to seperate digitizer and screen on the ace doesn't mean you could do that on the hox too. Just compare the space between LCD and digitizer of both devices and you'll see what I mean.

You wont manage to seperate the screen from the digitizer trust me, i tryed it and the glue is too strong + the lcd is too fragile.

Replaced screen but still not working.

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

[Q] LCD replacement, help

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.
