monitor powers on. No CCFL lights are on, just the green "on" light. after about 5 seconds, the CCFL tubes flash (still with nothing on the screen) and then the whole thing shuts off. It will keep going through these cycles until the plug is pulled.

What is causing this?

- Actually it was bad caps on the psu board. i replaced those and presto. Inverter boards are usually alright...it's the fact that if a cap is bad - it pushes WAYY too much power to the inverter causing the CCFL tubes to not come on.

-   I've replaced the suspected caps but still got the same blinking power indicator. 12 Voltsdc coming from psu line to video card. I disconnected psu and connected a 3 amp 12 volt dc external supply and the monitor works. -   mertjonjan
