Re: Dead. External power supply is good 12V but monitor...
My 12 power supply was only 500ma, not the 4a needed. Got the monitor to power up but now the screen goes dark after 2 sec. Looks like a bad backlight issue. I'll replace the inverter board.
thanks
jmmancini, It is only a guess, but possibly the CCFL "inverter" supply inside monitor has failed. Could also be fuse inside monitor on printed circuit board. You or tech will need to inspect inside unit for circuit causing this fault. The inverter board could also have a shorted device on it which will blow a fuse or send black brick into shutdown mode. 12fixlouie
