Flip the inverter upside down and hook the lamps up in reverse order. Does the dim part switch sides? Does the part that was formerly dim appear to light up properly?
N Channel FDD6690A seems a satisfactory replacement for the P2804BDG. The hard part is finding a good replacement for the P-Channel P5504EDG. Too far out of spec and the inverter will shut down. Parts that do run can run hotter than the originals.

Niko-Sem parts are easy to get in China.
There is no dim part, all the lamps lights up together. Test it one by one, also lights up. Anyway i tried your suggestion and all lamps lights up like before. I'm wondering why the monitor goes to standby after 'no signal' shows up in screen. Other folks have the green light all the time, just the backlights shutting off By the way, sorry for hijacking your thread.

Every monitor I have does that. It is a power saving feature. At least it is if there is really no signal - if it does that when there is video going into it then there is a problem.

Can you get into the menu before it shuts off? Some monitors will stay lit if you press the menu button right after it is powered on, even with no video signal. Others (for instance some Viewsonics) will not go into the menu if there is no video signal and will blank anyway.
