Blinking screen before black screen
I cleaned my screen with mirror cleaner, after few minuts its suddenly goes black. I restarts the computer and its okay, but after login its blinks a few times and goes black. Afterwards i can restart it (I hear the startup sound and fan is spinning) but just black screen. After 30 min it can startup again until login, then its the same again, blinking and goes black. There are no backlight. On external screen it register the screen but its just total darkness.
Any idea what causes the problem?
Is this a good question?
