Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

I have the same problem, mostly when the monitor is cold. I found a work-around tho. You bring up the menu, scroll through the options and select "memory". hit that it it does a memory reset, take about 3 seconds. After that, my monitor works perfectly. One time the power button stopped working and I had to unplug to turn the monitor off but it didn't do this for the last two days. Best of luck.
