I've just replaced my HTC One M8 digitizer assembley and the phone will not boot up and just displays a rainbow array of pixels covering the screen.
Does anyone know what might cause this. Before I replaced the screen I replaced the SIM card assembly and tested before I reassembled the phone. In the process of re-assembly I tore the ribbon that was attached to the screen, hence the need for a new digitizer assembly. I've checked over and over to see if there's a loose cable or damaged part but to no avail.
Can anyone give some advice?
Regards, Mark

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.
I have hardware version 0003, the display works fine just the top glass got cracked, can someone point me in the right direction for a new digitizer assembly? I found one on amazon new for 24$ but have no idea if it will work for my phone.0002 vs 0003 I read have different ribbon cables.
Sent from my EVO.
When this happened to me, I couldn't tell that the LCD had also cracked. I bought the digitizer only, and when I took apart the phone, I realized that I didn't have the parts I needed to fix it.
I can tell you that the correct P/N for the Novatel screen is 2V6A, but I am not sure of the P/N for the Epson screen. Check which screen you have by adjusting the brightness.
If when you adjust the brightness it switches with a fade effect, then you have a Novatel screen and you need the 2V6S ribbon. However, if it switches quickly and suddenly from one brightness setting to the next without a fade effect, then you have an Epson panel and you need the other ribbon cable.
So, I know it's been posted a lot in other places but I couldn't find like, a definitive answer as to if there are different digitziers? Am I just confused?
I would like to try and just replace the digitizer and glass over top of the LCD, my LCD works fine, the cracks are really thin and only a few going across diagonally. It fell from maybe 2 feet off my lap onto a parking lot surface.
I understand there is two LCD pannel types like you said, but are there two digitizer types/sizes?! for that ribbon cable.
I'm completely comfortable with taking it apart, I'm just worried I'll get the wrong part and find out the screen is also cracked and have to end up not using it for days until new stuff ships.... bleh
I've found digitizer+glass on amazon for 24-30$.
How do I adhere it to the LCD though, says doesn't include anything to do that.
EDIT: Found this gem: http://www.durapowerglobal.com/HTC-EVO-4G-Digitizer-Adhesive-_p_1166.html
Adhesive wont be a problem I just need to know about the glass/digitizer
EDIT2:
OKAY, if you want to ignore all i've said so far here is my real question of what I need to know.
http://www.durapowerglobal.com/HTC-...iginal-With-Installation-Adhesive_p_1103.html
Is there only ONE digitizer/glass piece on any given HTC EVO 4G? Or is there two different types like the LCD?
Hi i have cracked screen in my NEW (!) desire .
There is only a small hairline crack visible in the glass underneath the outer cover of the phone (i assume it's the screen - as seen on the famous tj's tear-down photostory ). The outer glass is completely intact (how the F#$% did that happen?).
When the phone is on the screen is all green, yellow - like a leaked lcd.
So here goes my question: how do i check/know if the digitizer is fine? Or will i only know it after i replace the AMOLED screen?
No expert here, but as far as I know digitizer has to do with the touchscreen, so I guess that if your touchscreen works(font mean the display) the digitizer works too...

Heh,
that is exactly the problem that i don't know if it works. Phone boots normaly, but i can't see anything on the display so i can't see if the digitizer works the straight-forward way.
I think the only way to check that would be to connect the phone to the computer somehow and see some "telemetry" - i was hoping for a suggestion in this area
You can try to use adb logcat boot up your phone and try to push various buttons (blindly ) if logcat shows interactions, digitizer should be fine.
i tried to connect to logcat but it's impossible if the "usb debugging" feature is disable in the phone.
Nevertheless i replaced the display and the phone works perfectly now
(note to self: do not boulder with your desire in your pocket )
how to check that only glass has broken not digitizer? please answer me. i am going to buy phone which is working fine and has only cracked screen which is visible, looks like only glass broken handset, how to know if digitizer is damaged or not ?
Broke the LCD under the touch screen. Can't even reset the phone because I can't see the screen. The outer touch screen is fine. I took her apart and want to replace the whole casing, lcd, and screen. It's just easier than separating the screen and removing the lcd. I removed the motherboard. My worry is where the IMEI is stored. Is it stored on the removable motherboard or contained in the screen/frame unit?
I just replaced the front half of my phone due to a cracked screen a few weeks ago. This is a very simple operation that requires nothing more than a screwdriver, a fingernail or small blade, and a little patience. Once you replace it, your phone operates just as it did before. All flash and parameters are contained within the main board, not the LCD/Digitizer assembly.
lg g3 screen q's... lines on screen and seperate issue "bubble" between lcd and glass
Please see picture... 2 different phones I bought used, as-is
The phone that has vertical lines in the screen is funny. I know the most likely response will be: replace the lcd/digitizer assembly and it will be fixed, but I just want to make sure I cover all the bases before going there. I pulled it apart and reseated the connectors, which didn't change anything...
**the interesting thing is that when it first boots up (first second or 2), the lg / life is good logo displays normally with no vertical lines...then the lines show up as in the picture. The digitizer (touch) works normally on this phone
anything else I can check with the lcd or ribbon cables?
copy and paste picture I can't post it due to being a new user, if anyone would be kind enough to repost it in a reply that would be great!

On the other phone (which touch and lcd work fine on) it looks to me like perhaps the digitizer was replaced and is too close to the lcd in the center (touching) or maybe water damage or something like that but not sure...
any advice on how to carefully try to repair this?
Both phones were purchased used as=-is with no history so no warranty or anything like that obviously.
Any input very greatly appreciated
