Question about Computers & Internet
When I turn my monitor on, it will stay on for a moment, and then go black. I can turn my screen off, it will come back on, and then go black again HELP Our starlogic 20 inch widescreen monitor screen keeps shutting off. It comes on for about 5 seconds, then goes black. In order to even shut the computer down, you have to turn it on manually, try to click shutdown, the monitor shuts off, turn on manually again to click shutdown, etc. It is unuseable!
This is probably a back light problem. Take a bright flashlight and while the monitor is on, point it at the LCD and try different angles, etc. If you can see an image, it is the back light, probably the back light voltage converter unit in the lcd. It could also be the back light bulbs.
If you don't see an image with the flash light, then it could be the main logic board.

Alternate power supply that doesn't have the switching adapter in between causes blackout, I went and found the original power supply and monitor is back up and running.
