Hi there, I'm new to the forum.
I'd like to ask You people a favor. My compal Em599 monitor went off lately and all I know it doesn't turn on, instead its blinking. I was looking all over the internet for some info about the power light error codes for it but with no luck. So I went looking for a service manual but also there are nothing to find about it. I opened the monitor hoping to find broken capacitors but the power PCB looks like new. Nothing suspicious, no sign of burnt electronics, nothing in it. Don't even know the voltages to check without the service manual. I can provide the picture of the power PCB if You like. The power light on it behaves like that:
After powering it the light is orange, then green, blinks few times orange\green then stays in both orange and green for about 3s, goes off and the sequence starts over. Screen stays black for all the time. No reaction after connecting to PC. PC is fine for 100%, checked with different display. Normalny it should turn on, show "no signal" and go to the suspend mode. I need service manual or error codes description at least. Please can someone help me out with it? Thanks in advance.

Reminds me of:

Shouldn't hurt to try (he says).

Either that or possible a 'looks good, but still is bad' electrolytic capacitor. Board numbers might help.
