Help with Black Screen on LG L7 - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

Hello!
I'm having trouble with my LG L7 (p700).
Some weeks ago I installed a rom, and after that it stopped working.
For now on, when i press the power button the screen lights up but stays black. And when it's charging displays a battery icon with the charge percentage.
I tried a lot of times using KDZ to flash a stock rom but it doesn't finish the flashing, or sometimes my pc crashes with a BSOD after some time with the KDZ program opened.
Also, using any combination of buttons doesn't do anything besides the light up black screen or turns off the phone, i can't acess cwm recovery, or even emergency mode, it's always a black screen.
Please someone help me, i really need to use the phone.

[Q] Help. have bricked my expo.

I was wondering if anyone here knows of a way to unbrick an Expo.
Just got phone today and was flashing the lastest dragonstorm rom onto it when My computer crashed and I recieved a blue screen. Now when I push the power button the green light and the backlight turn on but the scren stays blank. Have tried re-flashing with both the LG update rom and the dragonstorm one but the only effect is occasionaly the 'Emergancy download' message comes on and stays on until I pull battery out.
Have you tried flashing with a different computer? was your computer running vista?
No. My computer is Windows 7. Have tried flashing on a laptop running Xp but the dragonstorm rom comes up with a message saying can not read whats on phone. Have also tried with the base rom and update rom but both go right through and say update complete but the phone is still the same.
My phone is "bricked", it won't load into the orange windows logo screen anymore, just LG logo and turn lcd off, that's it. Help
Try, Power on + space key, then you should see "emergency download".
And then try reflash phone.
up help then....

[Q] G2 Black LockScreen and Hangs

After flashing Stock JB KDZ using FlashTool, my G2 became useless, when I boot my phone, LG logo shows up but LG Animation Logo doesn't show but there is LG sound and blue/green LED lights are flashing. In download mode, it doesn't show the usual "Firmware Update" screen, but it only shows stuck LG Logo, however I can see that my PC detects my G2 in download mode. In my homescreen, whenever I operate my phone and open some apps, the screen just randomly freezes but I can hear touch sounds when I touch the touchscreen panel. So what I always did is to lock the phone using either Power Button or Double tap to make it functionable again but whenever I will unlock my phone, a black screen comes out, and I have to lock and unlock the phone several times before I get the luck to see the lock screen and unlock the phone. I already flashed my phone several times to Stock JB using FlashTool, but still the problem exists. I also tried hard resetting my phone but the problems is still there. Do you guys have any ideas about my situation? Is it a hardware problem now? or it's just a software problem? Thanks. Hope you guys can help me. I will very much appreciate your help. :good:

S4 black screen everywhere

So this happened when I installed latest version of LOS14.1.
Basically happened to me 3 times, the screen won't turn on after I lock my phone, reboot doesn't help and there is no logo on boot. Black screen in recovery and download mode. I managed to enter download mode and installed stock firmware but the phone screen is still black.
When it first happened I managed to 'repair' the screen by pressing power button for some time. Second time it happened I got lucky again and screen turned on so I did factory reset. This time I can't do anything, I flashed the stock firmware and the screen is still black with blue LED on. I'm out of options and have no idea what to do, I am going to open my phone tomorrow to check if some cables loosened up.
