Hi, i had this problem start earlier where my monitor turns on for about two seconds but then just comes up with a black screen. The light stays green and if i turn it on and off the picture comes back for two seconds before going off again. I have tried the monitor on another computer, but i'm getting the same issue.

Does anyone know what could be causing this? I read somewhere it could be the capacitor's on one of the boards, but when i took it apart they looked normal.

Thanks.

EDIT: i should also say i think that i saw the screen flickering earlier this morning, I cant be completely sure though as i wasnt at my desk at the time and only saw it in the corner of my eye.

it's probably a problem with the inverter ( https://en.wikipedia...i/CCFL_inverter) and will need to be either replaced or repaired, i have read that turning down the brightness can be a work around that may stop it happening too.

Thanks i'l take a look. The only inverter i can find ships from China, so i'l probably have a go at repairing it myself if i can. unfortunately the brightness buttons dont seem to respond when it's on, so i cant seem to change that.

What i cant understand though is everyone is saying i should be able to see the picture if i shine a light at it, but i cannot on my monitor.

needs to be a very strong/bright light source and shone at an angle to the screen i believe for best chance to see any image on the panel.
