Good day, all. Been lurking for a week, trying to figure out what may be wrong with a friends P2370 monitor, but I thought I'd finally ask for assistance. 
It was working fine, until one day last week he turned on his computer and the monitor powered up, but no screen appears - neither a test screen (when no DVI cable is plugged in), nor a screen from my laptop (the Samsung does get detected fine by Win7, and I can clone/extend my desktop to it, but nothing ever appears). The flashlight test doesn't show any picture at all, so it's not just a problem with the backlight (although based on other statements made here that may or may not work all the time)...
I'm not seeing any issues with caps (ie. bursting/leaking), and the fuse (F301, a 5A Littelfuse if their datasheets are correct) shows okay (a continuity test comes up ok, multimeter set to 200 Ohm comes up with 0, not infinity) from what I can tell.
What else do I need to check? This monitor has it's transformer external to the monitor on the power brick, so at least it cleans up the guts of the monitor a bit...
I can tell that 12V is coming across to the inverter section, so it is getting power - I guess I can check if the CCFL's are broken/dead, but that requires ripping apart the monitor even further, eep!
I will put up some pictures tomorrow, if that's okay.
Thanks!
