Hello, I have a problem with my P3600: when I turn it on it remains on a black screen and does'nt go on, only the leds are flashing but the screen remains black. Sometimes (very often) it turn on completely but it's very very slow, I can't neither turn it on normally nor in bootloader mode. Do you have any suggestion? Thank you very much
Sounds like the flex cable may be loose. Do a search here, there are guides on how to disassemble Your phone and fix this issue.

Hi all,
I had a touchscreen issue (sometimes not working) in my HD2 so I ordered a new fabric screen+lcd assemby. I replaced it very carefully but now when I plug new lcd it is not working. Phone is working, buttons, vibration, hear the sound when turning on but there is only backlight on display and just shows black screen. I am sure that display is ok because I tried to put old one (wich was still working before replacement) and it has same issue (backlight works but display is black). Can you give me some ideas what is wrong ????
damaged lcd ribbon connector on mainboard or ribbon not being inserted fully or latched securely
Ty booting to bootloader ...
Help
The flex cable is not attached correctly or the main board is broken and before you close your phone try it. If you can't do this give someone your phone and he will recover for you.

Yes I have read this before but I think that white screen problem is not sloved in this thread. But maybe I could be wrong.
hi everyone, after some white stripes show up from nothin while i was using the gps and the weather was a bit hot and that maybe damaged my screen. So i changed the wole screen. Some white stripes shows up on screen when i put the back cover on. For example if i turn of and put the back cover and turn the phone the stripes will appear. But if i remove the back cover and turn on the phone it wont show up. And sometimes when i turn on the phone with the back cover the screen gets grey aand i cant see so i have to turn off and turn on again.
I think maybe the flex cable might be broken.
I tried dissembly the phone twice but the problem still here. I tried going back to stock rom(JB, KK and LOLLIPOP) but nothing help
if any1 know what is problem plz tell me adn sorry bad english
Edit:
The problem Was the flex cable that was broken
Hey there, I'm having some serious trouble with my S4 i9505, I recently did a LCD and digitizer replacement, and the connectors are connected, but the phone boots up with a green screen (pic included) the blue led notification light turns on, and the boot up music plays, then the home row button backlights turn on, and it also makes notification sounds, so it's alive... but nothing visually so to speak. I've tried almost every troubleshoot suggestion under the sun; but to no avail. Anyone else out there who has experienced this and could give some insight as to a solution? Much appreciated, thanks.

If the connectors are connected then the screen is probably dead.

I doubt it, since the screen does flicker when I press the power button rapidly a few rings, and the LCD and digitizer are brand new, replacement parts I had ordered, so not sure what the underlying issue is... going to take it into a repair shop it seems.
Hi, i know it's an old issues and few solutions are posted out there, but none worked for me.
symptoms: phone turns on with sound, vibration and top led, menu and back buttons all lit, but screen black, it even responds to touch from the sound it gives.
although, i noticed a way to bring the screen alive for sure is to plug usb cable to to charger then turn it on and screen comes alive.
i don't think it's hardware problem, or flex cable disconnected, because when it turns on it works flawlessly, and as many know dismantling the s5 to check is a real pain.
and if it's a software glitch, is the MM update that's coming out will fix it?
anyone with real knowledge of this issue and ow to fix it, please help!!!
flash stock using odin maybe? idk
Bought a screen on ebay, took it to a friend that replaced it soo bad that he even cracked it.
Other than that the screen is ok.
But there is a problem when I block the screen pressing the power button, after pressing it again to resume what I was doing it won't turn on.
I mean, it turns on but with stripes and lines black and white.
Initially is all black, then it turn slowly white. the touch digitizer is working but the lcd has serious problems.
Turning completely off the phone reset this.
Someone can help me find out what it can possibly be?
Some wrong contacts?
Thanks so much
Did you fix it?
My D802 after two years of display replacement, started to perform laggy and I can't unlock the screen once it is locked. I can see a low white light in the background but the display dont turn on.
