Samsung Galaxy S4 - Black Screen - Android Q&A, Help & Troubleshooting

Hi,
I've got a galaxy S4, but it has the black screen issue. I've tried doing the static clearing, charging it fully, discharging etc. So eventually I decided to buy a new LCD but that hasn't fixed the issue either. It responds to touch etc, just nothing is appearing.
Any suggestions?
Thanks

Jittery touch screen when not charging

Hi all,
I have a little strange problem...
I've read threads people report they have a problem with the touch screen calibration (gets jittery, activates parts of the screen without touching them, etc.) when they charge their SG2, but when they disconnect it the problem is solved.
Well, I have it all backwards.
When my phone is charging, it acts fine. When I disconnect it, the touch calibration gets all funky.
Any ideas on what to do?
Some specs:
It's a I9100G, and I recently went to a phone lab and changed my screen (got broke). Running CM10.1 latest nightly.
Thanks in advance!

[Q] Green screen after digitizer and screen replacement

I just replaced an oled screen and digitizer for a Samsung Galaxy S3. Everything seemed to go ok except when I turn the phone on the Samsung logo is green. The entire screen also has a green color to it (more than just a tint). Is it possible I just received a faulty screen? Or did I do something wrong? What could be causing this? I am fixing this phone for my friend's wife and would appreciate any help I could get.
possibly a bad connection
I did try the lcd connection again and that didn't change anything. How else can I check the connection?
Could it be anything else?
If not the connection, faulty screen

[Q] Samsung Galaxy Tab 10.1 Touchscreen NW

I have a Samsung Galaxy Tab 10.1 that was brought to me with a broken touchscreen. The screen was responsive even with the cracks. A new OEM screen was ordered and installed. The First screen was unresponsive, believing it may have just been a bad screen I tried a second Brand new OEM screen but the device is still unresponsive to touch. There are no signs of damage to the connector, the board or any other component. LCD is clean and clear with bright display. Device powers on, Volume controls functioning, Battery level full and holding positive charge, at a lost as to what is causing this issue. Anyone have any ideas?
Not sure. I am having the exact same issue with mine. If I find a resolution I will be sure to share it though.

ZTE Grand X In weird screen bugs

Hello, I'm new to this forum, and to Android too.
So my problem is this, i have ZTE Grand X In and i have problem with my screen. I have 2 years warranty for the phone and i already gave phone to the service in T-Mobile. They replaced the LCD screen, they gave my mobile back,but the problem is still there. Sometimes my screen is black but the screen is reacting to touches not a problem, but the screen is black, it is turned on but it's black, and sometimes it turns on, but some glitchy lines, white and colorful lines is showing on screen. I don't know if it's graphic card or motherboard or something. I already tried recovery mode {power,volume up,} {power, volume down} {power,volume up,home button} {power,volume down,home button} and it doesn't work after all. I really don't know what to do.
If you could help me i would be happy.

Screen doing weird

So I opened my s2 to clean the lens of the camera, but after assembling it, the screen began to do weird.
I've tried flashing stock rom through odin (succes) but the screen remains like this (it doesn't freeze).
The screen has weird colors and bordings around the samsung logo.
I've pull off the display thing from the slot, cleaned it up and put it back in, still the same.
Any idea how to fix?
(if I need new screen it will be bye bye s2)
