My phone LCD backlight went out but other than that worked fine. After installing a new screen the phone will not boot past the moto logo.
I can get into recovery and charge only but if I try to boot normally it goes blank after the moto logo not even showing the boot animation.
Reinstalling old LCD allows it to boot but with no backlight is unusable.
Anyone have any ideas?

Assuming you are 100% sure you've hooked everything up correctly, it sounds to me like a faulty/incorrect screen. I've read about this happening to other people (Bionics, though), luckily (so far) I've never had any issue with any screen replacements.
I'll check the connections again. The replacement screen came from a damaged Droid 4 that would not even show the moto logo.
I was lazy and rather than open it all the way and replace only the screen I swopped the whole upper part of the phone slide. I'll try doing it the right way.
Edit: checked all connections and tried again. Still no go.
Where is my torx 3 bit!
Edit 2: tried again. Still works with old screen switching only the screen (and the things that CAN NOT be separated from it) still won't boot. looks like I need a new screen.
Did you buy a broken D4 and try to swap the screen? If so, that unfortunately might be why it was broken in the first place... The plus is that might then be an easy fix too... Then you'd have two!

I did get a broken D4. It had a bad board and would not even show the moto logo.
What's really strange is yesterday it was still not working and today it booted fine but now the touch screen is not working.
I'll keep trying to fix it.
Honestly it sounds to me like the front portion is busted. Perhaps it is just the digitizer that is broken, those tend to be much cheaper than LCDs...
Good luck and let us know how it pans out, it is always good to hear solutions to hardware problems!
Both touch screens/digitizers work with the lcd that has a bad backlight but not the one with the good backlight.
I examined the LCD with the good backlight and found a very small tear in the ribbon. Looks like I found the problem.

Hi, i'v got a problem. I tried change my digitizer and, when im done, now lcd doesn't work, because it is still white...:/ What can i do now? any solutions?
Thanks a lot
Check your connections. Pull apart and re-seat everything to ensure everything is hooked up good.
everything is fine :/ still white screen
Perhaps you zapped or damaged the LCD when you were working on it...
You could try replacing the LCD too -- but at this point I think I would send it to the professionals
HTC repair or someone like PPCTechs
Don't know if the screen set up is still the same. But when I replaced the screen on my Universal the wiring for the touchscreen was stuck down onto the lcd wiring, as they both shared common earths. Maybe worth a check before spending more cash?
i have the same problem, the screen was working fine before i replaced the new digitilizer and now its just white but i can hear the tablet playing so it must be the screen.i checked all the wiring 4 times now! any idear???
:crying:
Slide the phone open and apply some pressure near where the angle of the opening is (back of the LCD below the SIM, where there is a bar). I had the same issue and this fixed it.
My tilt is acting very nasty lately. Over the past few weeks, I noticed that when I turned on the display, occasionally I would get something that looked like the static that you see on TV, but with colors. I would just turn off the screen, and turn it back on to clear it.
Now it's gotten worst! 98% of the time, it intermitantly gives me a blank solid white screen when I turn it on. Occasionally I can just turn to screen off, and on to reset it.
I'm running OEM WM6.1, and I've tried to reinstall the OS, but it didn't help. My phone has taken a beating, and the top corner has had a small crack in it over the past 2 months, but it didn't effect the touch screen, or picture. I also took off the cover to make sure the cables were all snug, and it didn't help.
Any suggestions?
Something got corrupted. If you search WIKI, it's call the 3 color screen stuck .. and you're better off posting at thread below. I hope someone can give you help (if you follow those steps and still no good)
As rule of thumb, do a lot of reading first

On a second thought, it might be the LCD itself broken ..
Oh, believe me.. I'm not one to turn to the forums without doing research myself! All the research I was coming up with seemed to point to a slightly different WSOD though. I think you are right about the screen being broken. I've reinstalled the software, and it acts up even when booting up!
Unfortunately, I'm not impressed with ANYTHING on the market to date! If I'm unable to fix this, I'll just go back to a RAZR until the next gen WM7 phones come out. (With a tilt screen of course!!)
Oh, and even though the screen goes white, it's not stuck, as it fully boots up; I can hear sounds, and even activate the touch screen.
Also, I forgot to mention.. the first problem I started experiencing was that my tilt would go back from landscape mode! It was like the video board was crapping out. I could even see a slight flicker in the display from the refresh rate.
hi i think you may need a new Need a new flex cable ribbon as i had the same problem once
Thanks Tayzaa, I think you could be on to something. I'll open it up and take another look!
Hi!
is this problem solved?
WSOD is bug of Hermes. I would know if kaiser have the same WSOD-bug with D-pad?
Thought this was going to be an easy repair. Obtained a new screen from Repair Universe (Really quick). Followed the video and several take apart guides. Put the phone back together, turned it on, Get the Motorola Logo screen, bottom keys light up and then the screen goes blank, Have to pull the battery to shut it down. SO, I put the old screen back in, turned it on, Motorola Logo again and the then the screen dims to where you can hardly see what's there, but it goes through the boot process. Anybody have any ideas as to what the hell I did to screw it up? Swapped the screens around several times hoping I'd remember something and magic would happen but no such luck!! Thanks, Howie
Replacing the Bionic's LCD is one of the simplest phone repairs I've ever done. It's possible you got a faulty screen, or it's possible that the LCD is not your problem. I've purchased from them a few times but never had a problem...might want to check what their return policy is.
Yeah, plug and play! Should have taken 30 minutes tops? What has me puzzled is the old screen dims right out now so I screwed something up? Sorta hoping this happened to someone else ans they figured it out before I send it in for repair.....

Couple questions I had which may help clarify a few things, and could help in troubleshooting or finding someone who had a similar problem..
Why are you replacing the screen, was the screen dimming before you tried the replacement or only after?
Are you running stock blur or are you rooted/rom'd?
Information like that can go a long way to diagnosing the actual problems.
It's rooted and it's not a stock rom. I bought the phone and the LCD screen was damaged, so I ordered a replacement. I could still use it with the damaged screen but it had several white lines going down it. I rooted the phone and loaded a different rom before I switched screens and it was fine until I switched lcd's.

It's probably a faulty LCD in that case, as long as the old LCD is working as it was. If not then perhaps you damaged the back light circuit.
The old screen doesn't work anymore. Correctly anyway. The old screen is real dim?

I would have to agree with brandogg, could be the back light that is having the problem and that is why the old broken LCD is going dim now.
I'm assuming that the dimness problem occured only after the install of the replacement LCD since you only mentioned the lines as being the original problem.
One thing you could check is if the auto brightness is enabled. I would disable that and set the brightness as high as it will go and see if you still have the dimness issues.
That's when the dimness started on the old screen, after I installed the new one. I'll try to check the brightness after work. Thanks for the idea. I'll post back.

Hello,
I have sent my gnexus off to be repaired this week and recently started to use my old milestone until my other phone is repaired. Phone was working fine, a little slow to my nexus but it was better than nothing. I was checking my emails and stuck my phone in my pocket to cross the street, when I pulled it out again, the screen would light up (glow) but the screen was black, I tried pulling the battery and rebooting but to no avail. I can feel the phone vibrate when I slide my finger across to unlock it and tap icons, but nothing is being displayed. I'm wondering if anybody else has had something like this happen and if it is possible to fix relatively easily?
If you don't get anything on the screen anymore I'm afraid it's a hardware failure.
Maybe the connector cable is broken (partially), I guess...
I guess Eiertschik is right.
In the boot process, does the M logo show up?
Hello,
I know a lot of us are having problems with displays and digitizers and im wondering if anyone else has this problem. Yesterday i replced my screen because it had a dead zone. I booted up the phone and everything worked great until i locked the screen. When i pressed the power button to unlock it there was just a black screen with lots of white lines forming. Without fail the phone will do this. I restart and its fine but when i lock it, it gets screwy. I really need to get this working since i dont even have a backup phone right now. By the way the display is not oem its a knockoff.
Since you change your LCD....it might be a different panel from your original. Check your kernel or flash the kernel again.

Same thing happen to me about a month ago during my G2 screen repair. I bought mine on ebay from a seller that had sold hundreds of them, figured I couldn't go wrong. Unfortunatly I never figuered out why it was failing and just ended up returning it for a refund. The second screen I bought was from etradesupply and it worked perfectly. Hopefully someone has a fix for this weird issue.
I had that exct thing happen to me, well rainbow colored lines. I shattered the screen on a corner drop. I took it to Gopher Mods, they replaced the screen and within a few minutes it happened. They replaced it 2 more times and eventually the last time the screen popped out a little bit since they did not add enough glue/sticky tape inside and the lines dissapeared. They also gave me a full refund, with which I got another G2. So two working phones now lol.
Basically the screen might be pressed in too tightly causing the cable inside to be kinked too much. Its very easy to damage the video cable in this phone mind you.

Try installi mg dorimanx's kernel which detects your panel type of search the thread for a kernel swap flashable. Your new panel may be of a different type causing the white lines.
