Question about HP L1955 19" LCD Monitor
Monitor powers on, will blink an actual true display, then goes off and will not give another display unless the monitor cable is unplugged and plugged back in and then it only blinks the display and goes off again.
I can't seem to find any schematics for the power supply - which is my guess.
Check the capacitors on the power supply if any on the secondary side are bulged replace them all with low ESR substitutes. Panasonic FC work well.
Also check the transistors around the inverter output transformers there are two on each side. Check them with the diode function of your DMM if any measure shorted replace both in the pair. You can find these on e-bay.
That is a power board / inverter assembly getting it would be extremely hard not to mention expensive.
