Question about Samsung SyncMaster 204B (Silver, Black) 20.1 inch LCD Monitor
I have a Samsung flatscreen monitor (not sure of model, I am at work). I have had it only a little over a year. Yesterday a problem began. The monitor power stays on, but after viewing screen 2-5 seconds it clicks and goes black. To get a picture I have to turn it off and on again...to be able to view screen for another 2-5 seconds. Any suggestions on what this might be?
Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.
