Screen goes dark after approx 2 seconds? - HP Pavilion F1703 17" LCD Monitor

If my memory serves me right 3 is no PMW signal from the main to the PS board, you can test that voltage and see if its around 3 volts

You should try a factory reset, just google the make and model for instructions to do the factory reset, if that doesn't clear the issue you need a new phone.

this is caused by the panel's edge contacts coming loose(delaminating). would have to replace panel(approx. 1500.00 usd.)

Replace cmos battery.

The power supply caps need replace on power supply, or replace power supply.

It has bad lcd inverter and Westinghouse don't sell the parts either.

check your video card... place it again

This sounds like bad inverter board.
Every time LCD goes from Standby to ON state - Inverter Board resets it’s self for approx. ~1 sec, during which time you should see blue screen.
Problem is that board detects problem with voltage/current on one of the seven transformers and shuts down automatically...
As to the costs:
- BestBuy repair service approx.. $600.00
- Buy new Inverter Board & repair LCD your self approx. $200.00
- Another option is to repair Inverter Board, but parts are sometimes hard to get...
Now for the DON"T TRY THIS AT HOME or AT YOUR OWN RISK solution:
-The cheapest method is to bypass protection circuit, by transferring good signal from working transformer (using 10nF/250V capacitor) to detection circuit at the faulty transformer.
Then watch movies on your LCD unlit BAD transformer totally BURNS-OUT.
This will be obvious by dark stripe about 1"-2" tall across your display.
Hopefully the only damage will be to the transformer and not CCFL (light behind your LCD), but when you are faced with a choice of using it for a while longer or throwing your LCD to garbage right now... to me this choice was simple.
Good LUCK.
