Hi There,
I bought a Spring LG G2 LS980 on ebay with an non-working backlight with cracked screen. At the moment, I thought that the screen was broken beyond the LCD and that replacing the Screen, LCD and Backlight it would work. So I bought a new screen and replaced it like any other G2, but now the phone turns on and sounds tell me the phone is working and responding to my touch, but I can't see anything! The status LED is my only indication if the phone is off, booting, on or charging. Is this a software issue or am I gonna have to replace more chips? Thanks,
Sincerely,
Sohaib
EDIT: So i did some testing around, and it seems like the flex assembly with the power buttons gets super hot when the phone is supposed to be on. When I press on the lower right contact between the screen and the assembly, the backlight flashes for a moment, so it looks like the connector is damaged. It is a hardware issue. Thanks,

Hi,
My HOX touchscreen was broken, the touch and everything was still working. I ordered a replacement lcd display Unit and replaced the complete display and touch. After replacement the screen is completely black but the phone still works. The touch buttons on the bottom still work and i can use the volume buttons. I replaced the lcd display unit very carefully and i am sure nothing is broken etc. So the touch is working but the screen is black. I tried 2 display units and both show me a black screen.
Does anyone know how to solve this problem? Did i forget to do something during the replacement?
Please, i need some help with this issue.
I`ve got the same problem. Have you found a solution?

Yes, it seems that the display units from HOX are not all the same. You have to check with display flex you have and compare it with the one you have new. I tried an other display unit and it worked for me.
Now i have the same problem for my friends HTC One X. Were looking now for the right display unit..

Ive swapped a few screens over on the one x and x+, I find the screens don't show anything until the phone is soft reset by holding down the power and volume up button for around 10 seconds (until the lights flash several times and then the phone vibrates before booting).
I have also found that the motherboards do accept displays manufactured by different companies (sharp, sony, AUO.. etc) the soft reset is a required step. If an identical lcd is used there is no need to reset.
Hope this helps!
HI Guys,
I recently replaced the digitizer on my wfs and everything went well, i have calibrated the screen and the touch is working perfect however the home search etc buttons at the bottom don't work, they light up but do not respond.
What did i do wrong? all wires are connected and as i said they light up!
thanks!

Just a whim here, but maybe it could be that the digitizers buttons don't work. It might be broken out of factory, where did you get it? Maybe you can ask for a replacement as the digitizer is most probably broken.
it was just a cheap one from china, so im sure i can get a replacement if i ask.
I wasn't sure if the buttons are actually part of the touch screen itself or if the need to have contact to something else..
Thanks
Hello,
HTC Desire got applied pressure on screen and it went dark. Nothing cracked. Still could answer calls and power phone down using touchscreen.
Then it was laying in a drawer for about a year.
After I tried to power on again(without SIM card) the lcd kind'a lighted up, vibrated once and after a while buttons lighted up, but there was nothing on screen. Pressing power button just turned button lights on and off.
So, obviously, I thought let's get that screen replaced :good: As it turned out, I ordered Samsung AMOLED screen, but apparently, mine was SONY picture (bad quality, shaky-shaky hands)
New screen doesn't light up when I power on phone, but it still vibrates once and then buttons lights up.
Checked all the connectors, reassembled many times, but it's still the same.
p/n is 99HKZ010-00 which should have amoled, right?
Should I try my luck and order exactly the same screen(SONY) and hope that there isn't any other fault, like faulty board or connections?
The box doesn't say if its amoled or super tft. Just 3.7-inch touch-sensitive screen.
Update:
well I can just delete myself
phone kinda works - I can start it, get pass lockscreen, can hear UI sounds when I press somewhere, in fastboot mode it gets detected..
So, I guess I just have to get right lcd replacement thingy and rock on!

Theres ur answer. If it doesnt say anything then its lcd. If it were amoled it would say 3.7-inch touch-sensitive AMOLED screen.
I hope that amoled display didn't fry or anything

All the connections are correct....and the phone comes on just the display backlight not coming on.
The funny thing is that when am in a well lighted room or i shine a light on it, i can see that the phone is on an i can access my apps.
make sure that all 4 ribbons in the lg motherboard is properly connected, check if some pins are dent or bended. if all seems to be good, the problem is the backlight of your replaced screen
Make sure there is nothing covering the proximity sensor!

where can i find the connection for the backlight?
Hello, did you find a solution.
I have the same issue, it's not the screen because when I change the motherboard, the brightness work.
Thank you.
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?
