[Q] Display do not turn off - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi,
since yesterday night the display of my Galaxy S does not turn off: when i press the lock button the display turn off and immediatly turn on, even if i wait the automatic block the same thing happen, and once it is locked it goes on: every 5 secons the display turn off for like 0.1 second and then it turn on again...
I was on JVR, this morning i tried to do a wipe, but it did not change anything, then I flashed the JM8 and with that firmware everything works correctly, but then i flashed the JVS and now i have the same problem...
The button seems working fine to me, t does not appear to be blocked.
Do you have any suggestions??
Thanks

[Q] Display wont wake up after sleep

Hi
I tried to upgrade to Froyo, that part went well..
But: After boot the screen is visible until I either press power or phone goes into "sleep"
Then next time I try to wake the phone up (via power or meny buttom) the screen will not turn on, I can see that the phone is awake because the two buttons lit up, and I can swipe the screen to unlock, but screen is still black.
If I reset the phone the screen starts again until next sleep or pressing power button.
One more thing, I cannot set the light level any longer.
If I go back to Eclair the screen works ok again, and light level (both manual and automatic)?!
I have now tried almost every how-to about flashing firmware, but not luck yet.
I tried to search for similar problems, and found similar but no good answer.
What shall I do?
Post in Q& A next time .
How did you upgrade and what firmware you used .

I have tried several, but last time (today) I used following, via Odin, I9000XXJPY from samfirmware.com
And thanks, I will post Questions in Q&A next time, sorry.

I will try it again and see if works this time (if I missed something first)

[Q] Black screen after lock

I've had my Nexus One for some time now, and i'm having a problem with it. Whenever i turn it on (sometimes i have to try more than once because it just stays black) it works ok, but when i lock it and try to unlock it (with the power button) the screen stays black. The action buttons at the bottom of the screen turn on but the screen stays black. I have CM 7.2 and i just flashed it and formatted all the partitions i could think of and it's still doing this.
If i call the phone after locking it, it will ring and the trackball flashes but the screen stays black.
Any help?
When the phone is on everything works fine.
P.S. I've searched the forums and found a few threads but none offer a good answer.
EDIT: If i leave it for like an hour or so i can turn the screen back on with the power button, but only once.
i have the same problem, am using the stock rom .. it happens after ending a phone call the screen stays black and i have to restart the device
waiting for solution !!

Freezes, reboot and other funky things

Sorry for my bad English
Hello friends of the forum, I present my problem. I was given to repair a S3 LTE really is driving me crazy. We'll explain: the owner did filth with ROM to the point to make it unusable. Turns on, but after a while it stops and turns itself off. I tried to flash the stock, wipe system etc .. from recovery and put back the stock, but every time I turn on the phone and get to the Initial Setup (the one that says Samsung GALAXY which allows choosing the language) crashes and off. Also known that the recovery is very very slow (both TWRP that stock that cwm). I managed to flash rom 2 including Cyanogenmod but this crashes. Sometimes the poor cell can not even start that hangs on and off. I tried to replace the battery with one that I already had and the situation does not change. I wanted to try to do an update of the bootloader because I think the problem is the. Further inform you that when it crashes but is charging if I remove the battery on the phone stays on but completely locked and I can not even press the power button for 3 seconds, because it is completely freezed. Another observation I have noticed is that if I leave him in charge when switched off the led solid red, the screen shows no signs of life and if the detachment micro usb LED remains lit sign that is completely blocked even when it is charging (WHILE TURNED OFF!). I hope you can help. I tried everything
Maybe it's power button problem.Check the power On/Off .

Click to expand...
Click to collapse
And those buttons are working normally when you turn on your phone (and the screen is on, too)? Can you go to home with home button or lock the device with power buttton?
Maybe just a hardware issue?
buttons
when i power on phone i can use every button normally until i block it :/
This sounds like really random issue, may be a hardware one. If reflashing stock rom trough odin didn't help, then you probably should give your phone to service
