Dell flat panel monitor

I have a dell 19" The monitor when I turn it on looks like its about to turn on (although the screen doesn't show a picture) and then the green power light keeps going from green to no color and green and no color almost like its flickering I know its not the video card because I tried it without hooking it up to the computer. I also have another 19" which works fine and I used the same power supply/cables. Is it stuck in safe mode or can I take the monitor appart and tweak something. Let me know. Anyhow who can truely help really knows there stuff.

It's a problem in the power supply section inside the monitor. It needs component-level electronic troubleshoting.

Does the fault appear on the laptop screen aswell? It appears by your description that the fault is only on the external monitor. If the screen comes on for a moment and then goes blank as described, then this appears to be an invertor fault. It is very common among laptop and tft screens and requires the invertor inside the panel to be replaced / repaired. Simply plug the screen into another computer to confirm.

Pavilion f1903 silver goes blank seconds after turning on.


The monitor you have has bad components on the circuit boards inside.
This is a classic problem with all LCD monitors.
I rebuild them on a daily basis so I recognize the symptoms.
I would suggest finding someone who can do component level repair on the circuit boards inside.
I also suggest not trying to repair yourself as there are many breakable components to them as well as components inside that do not like static electricity discharges.

Your power/inverter board is in need of an overhaul.
The capacitors are failing and possibly a transistor.
If the screen showed any redness or pink whebn it was working, Then there is a slight chance that one or more of the 4 lightbulbs in the screen was going bad and finally went.
If you take it apart and send me a picture, I may be able to tell by looking at it.

Bank Monitor problems


Unplug the cable from your PC, if the monitor shows a test image, the monitor is fine and the problem is with your graphic card. If you dont see nothing on-screen after unpluging the cable from the PC, then the monitor in damaged. Send it to repair.
