My att i747 s3 was water-damaged and I believed the screen was broken. I was able to view the screen if I connected it to a PC and even could control it, despite the screen being black. I noticed it actually had a very dull flicker of what was supposed to be displayed. I replaced the whole screen assembly and the problem persists. Any ideas?
I'm guessing It'd just be best to buy a whole new phone but if there's another option I would love to hear it.

So my screen hasn't been working for awhile (the backlight will light up but there is only black), but the phone still works; I can play music when I press where "play" should be on the lock screen, and etc. I've only recently decided to try and replace it.
I ordered a screen from eBay and it arrived today... here's where it gets interesting. After replacing my old LCD screen with the new one, the screen no longer lights up. I took it apart again and made sure I didn't miss any connections, but everything seems in the right place. Does this mean the problem is not the screen? Or maybe a faulty replacement screen? Any ideas?
Hi,
I dropped my note 2 and the display is blank after that. The motherboard is fine. The phone is booting up and the phone rings when someone calls.
However, even the touch functionality is not working on the blank screen.
So, what do you guys think, just a digitizer replacement will work? or do you think it might need a full LCD assembly replacement. If latter is the case, I might as well dump this phone as its almost End of life.
thanks,
Hi Guys, i am also facing the same problem. The phone was dropped and after an hour the screen started turning blue and within few hours the whole screen went dark blue ( or nearly black). The phone is still switching on and the bottom and side buttons are working but screen is black.
Do i need to replace the screen only or the whole display kit as asked in the first post?
Also i want to take backup of all my contacts,sms, whatsapp messages and other stuff. Is there any way i can do this when there is no display on the screen? Need a solution on urgent basis.
Thanks in advance
Hi all - having issues replacing the LCD/digitizer in my z1c. Initially I had dropped and cracked the glass - and the screen became unresponsive - although the LCD display still worked. I bought a replacement screen and during installation when I first turned it on to test it - there were vertical lines all over it, then after disconnecting and reconnecting it, it did never lit up at all. Hence I sent that screen back as defective. I now have received another replacement screen from a different provider. Similarly, after connecting and attempting to test it, this screen LCD never displays either. However - I can tell the digitizer part works because I can hear the screen beep when I touch it. Is there something I can reset to kick the LCD back into operation? I will say that while troubleshooting initially - I tried a full reset using the sony PC tool - and I went through a SW upgrade along with the full reset - so I bet I am back at the initial language setup menu - on the newest SW version. Can there be something screwed up with that - or with the firmware or something? Thinking its got to be something on the phone side, do to the consistant failure with different replacements.
Any help is appreciated - if I can't get this screen to work I'll prolly just give up on the darn thing and get something new.
thanks!!!

Hi Folks.
I searched the forum for related issues but only found one other user who never got a response. I recently took it upon myself to replace the usb/charging board and mic on my stock sph-l900 note II running 4.4.2. Prior to the repair the display was perfect. Anyhow i replaced the board and when I powered up the phone the display seems to have lost the ability to display black. The Note II launch screen looks brown, so brown i would call it woodgrain. I double checked all connections and messed with every every display setting, none of which solved the problem. The touchscreen still works, the phone runs everything beuatifully, but the display gamma is too high by at least .6 everywhere on the screen.
Is this a matter of dust between the digitizer and screen? IS this even a problem anyone is remotely aware of? I have a cheap replacement glass but that was not an endeavor I wanted to attempt. Any ideas what to attempt short of replacing the screen? Any ideas at all?
Hi,
I have to following problem:
My HTC One M8 has colorful grainy static screen and sometimes the picture turns off, like a cable is loose. I read all the forums and search google all over for a solution, most of them claimed that after a panel replace it will be fine. I switched the whole front panel for a new one, but after assembly i have the same problem. The phone is working, because i can unlock the screen lock, turn off the phone, i get the notifications and everything, but the screen is just static noise. I'm assuming that maybe it is some graphic fault, but not related to the lcd panel or the cables (they are all brand new, and i double checked all of them). Is the logic board responsible for the image? What should i try to replace next the upper motherboard, or the middle logic board?

I've got the exact same thing here.... Searched a lot around without finding anything that has resolved my case. I ordered a replacement screen for a cracked screen on the first phone, but when I tested the LCD before I assembled everything together it was showing just noise like in your picture. I assumed the LCD was bad, so I ordered a new one. But the new one was acting exactly the same.
Yesterday, I was approached by another one who needed help with their M8, and that phone needed to have its volume buttons replaced. So, I reused the parts from the old M8, but when I booted the phone after repair, it showed this same noisy screen as the first M8 I tried to repair. Anyone here that knows these phones and what is going on here? I'm pretty sure I have 3 working LCD's here now, and suspect something strange going on with the mainboard or controller for screen.
Anyone?
