Philips Brilliance 200w6cs Backlight off Green LED ONN

pay a repair shop to fix it

Sounds like a backlight problem to me. If you input a signal to the HDMI or Composite input and then it goes black have you tried taking a flashlight to the screen to see if the picture is still there but just dark? That would indicate a backlight issue. That model appears to be an LED edge lit backlight, so if the picture is still there after going black your going to have to trace out the backlight circuit and see whats going on. Usually with LED backlighting if it comes on at all then the LED's are good, its just the driver supply thats failing to keep them on. Some TV's have a small separate board that provides the backlight control, but i suspect with this model its on the power supply board and not the motherboard. Have you checked that board? It could be bad caps on the power supply board, check the voltages to the backlighting when it lights up and then when it goes dark. It could just be some failed capacitors on the power supply causing that voltage rail to drop off.

Try connecting wires up.

actually if u repair an aoc monitor alone without getting connected to cpu once u switch on the monitor all led's will lit on ( green light ) it will remain on situation until u connect the vga connector to cpu that's the time led's will lit off and only the power led will remain in green condition.some aoc 5en once u power on power led is in green condition and if not connected to cpu it will be in orange condition.hope u get some idea but i am not sure if it will work with ur monitor. but as long as LEDs lit on i think no problem with ur monitor.

Do you get anything at all on the screen--like white writing at startup?
Even if your video drivers have become corrupt, they are not used until Windows actually starts.
It very well could be the flourescent backlight has gone bad. Can you adjust the brightness/contrast at all to see anything?
If those controls do nothing for you, then you're looking to get a new monitor.
Your monitor does have a sort of power supply for the backlight and that could be bad, but if you're not into taking it apart, then you are far better off buying a new monitor.

"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.

Hi..there,
You've got a busted backlight inverter... Need to replaced a new one...

Hi...there,
Well...your backlight inverter are busted.... need replaced a new one or repaired it.

As in almost all lcd type tv/monitor the backlight will go out and the inverter should be replaced at the same time. Your cost about 50.00 if you do it yourself.

Take care

It seems to be an Inverter related problem in which backlight seems to be shiutting down.Is this monitor 3-4 years old???If so backlight of the panel could be an issue.
