Re: monitor only stays on for 3 seconds

There is probably a bad capacitor within the monitor that will not allow the picture to "hold" in the on configuration. This will need to be replaced. You can send it back to Phillips, or 17" monitors are pretty cheap these days. I would suggest a Samsung or BenQ. They both carry 3yr warranties.

Re: monitor only stays on for 3 seconds

Replace the CCFL lamps located in the LCD panel.Bad lamps may still light up, but draw excessive current, causing unit to shut down.

It switches on for just a second and then the screen stays blank

yetimonsta, Are you sure that the monitor is BLANK?? Or is it just BLACK? Or is it both BLANK and BLACK? Connect a known good monitor to your pc to prove that your pc is working correctly. What does your L90D+ do when connected to good pc. Have you done the flashlight test to evaluate the state of the "switch-mode-power-supply" when lcd panel goes black /blank??

Monitor goes blank after 3 seconds -Samsung SyncMaster 920NW

Could be a power issue. If it doesn't show anything at all then that may be the case. It may also be the display itself. It would be a costly repair so you might be better off finding a new monitor.

Normally when this type of problem happens, the first suspect would be the inverter board, then the filter capacitors and lastly the mainboard.
A defect in one of the lamps and faulty inverter IC may cause the display to shutdown as well. If the lamp is defective, it will send a feedback and cause it to stop producing output signal thus the display just shut off once you switch in ON.

Well the first and second paragraphs make me say the Inverter/power board must be replaced.

A white display typically means either your display cable (in your monitor) is loose or logic board is dead.

Either one of these things typically mean take it in for an estimate to repair, and if it's too much, buy a new one.
With your luck I think I might switch to big cheap CRT.

Blank Screen..Will not power off

The flash light test only works with lcd monitor as they have back lights. Double check the connections again, also, if you can borrow a monitor try it on your pc, it may be your graphics driver needs to be uninstalled and re-installed, but you will need a monitor to see.
