white screen after fixed touch screen :(

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.

[Q] Replaced Nexus One screen, now the screen won't turn on

Ok, so I broke the screen on my Nexus One. These things happens. I ordered a replacement screen, and thanks to numerous online guides, I (thought I had) replaced the screen.
Now, I guess that some other parts of the phone might have become damaged, but I doubt it. The phone seems to work. The touch buttons light up. The unlock gesture gives a slight vibrate. So does the volume rocker when I (seems to) reach the top/bottom of the scale.
But the screen itself doesn't show any response. No backlight (should I be able to see that). Nothing. What could I possibly be missing, I've gone over everything three times, but can't see nothing wrong. I've checked all the connectors everywhere. Somehow I get the feeling I'm missing something obvious....

Are you sure you bought an amoled screen replacement and not the slcd screen? That would cause such an issue.

Or maybe he needs an SLCD screen and not amoled..

I was going to ask if your wifi and bluetooth still work but i suppose you cant really test that yet...
I replaced my digitizer last week and now the phone works fine apart from the Wifi, Bluetooth and the charging pins for the dock at the bottom. LAME!

Maybe two Months ago I replace the full Housing on my phone is no easy task but not too difficult either. Check if you didn't ripped any of the flex cables and if the cables are connected properly. I have a long history of replacing housings and my best advice is to do again make sure you have time.

Exactly the same issue. Did you find a solutions?
I too had a broken screen. So, I ordered one from ebay and replaced it.
Now, it screen does not turn on though the icons at the bottom of screen switch-on.
I can here the sound when volume rocker is pressed.
Also, I believe that the touch is also working as I can hear the unlock sound when I swipe my finger across the screen.
Did you find a solution to the problem? Did I make some mistake or the screen is faulty?

Just months after the Nexus One was released, Google announced that the AMOLED Company "Brightstar" fell short of displays and was unable to produce more displays for HTC, so they decided to move to Sony to make the displays, To determine whether a phone has the AMOLED or SLCD display, The internal sticker on the back side of the screen assembly can be examined; part number 60H00443-03P indicates SLCD and part number 60H00287-00P indicates AMOLED, and as i mentioned, the AMOLED screens are gone so finding a replacement for that model would be merely impossible. I was looking around and thought that i may of found a fix to this, see, the HBOOTs on the devices are both the same except the top code of the screen that determines the screen type, if you were to flash the SLCD HBOOT, you might be able to retrieve a working screen, well its probably worth the gamble anyway since you probably are not going to find a replacement in a while.
EDIT: And after moments of posting, i found a AMOLED screen seller that will ship to Europe! http://www.ebay.co.uk/itm/LCD-Scree...K_Replacement_Parts_Tools&hash=item4d06825672

Dude, I dropped my n1 and shattered the screen almost 2 years ago. Bought a replacement screen and tried to replace out on my own. Needless to say, it didn't go so well, my n1 was is a paperweight. Good luck man! I miss my working n1...

LCD Screen replacement

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.

Strange problems

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.

Lcd is displaying only black!! can receive calls and text

Hello fellas,
I replaced my note 5 lcd before 4 days it was working perfect w/out any flaws but it suddenly went black while using it was full charged while it happend. but i can receive calls texts hear sounds. I tried a youtube fix by holding Vol down+Power!! Yes it does reboot the phone but whateva happens lcd is black, even i tried to flash stock rom also its succeed!!
I dont know what the problem is but my lcd was broken before, while in that stage it cannot boot or receive calls there was only a solid blue led.
But in this case i dont know what the problem is and i think you might help me figure out.

I had the exact same problem and unfortunately the phone had to be replaced under warranty so if you don't have a warranty on the phone then immediately contact whoever sold you the screen and get a replacement since that one's broken. It's not going to come back no matter what and it was probably a cheap knock off which is all I keep seeing all over the place but try anyway because they aren't cheap at all!!!

Sounds like when you had the LCD replaced they didnt do the digitizer ( that is the component that converts the signal to pictures for display on the screen) usually when one is damaged they are both replaced at the same time

I think you're a bit confused on what a digitizer is... It's not for converting pictures it's for dealing with the touch part of it I.E it senses where your fingers are on the screen.
