    I lucked out, found out the LCD is still under warranty. Charged $25 for "S&H". Glad I do'nt have to crack it open. Thx for the help.

    I had the same problem with noise coming from speakers. Finally the monitor would not stay on. I goes on for a second and goes blank.

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!

Hyundaip90wu screen flicker


Unfortunately, unless you are an electronics expert, getting this fixed may cost you more than getting a new monitor. If it is under warranty, contact where you bought it. One thing you could do is try this monitor on a different machine, but I think it would still flicker.

Lcd screen is flickering on and off very fast


Disconnect the lcd from the computer. Turn on the LCD and see if it still flickers fast. If it doesn't then go ahead reconnect the lcd back to the computer. If its still flickering, then go ahead and hook it up to another laptop or desktop. If it doesn't flicker on another computer then that means there is a problems with the video card on the original computer.
If it still flickers then that means the lcd is bad and would need to be replaced.

If you bought it new in this last August, don't put up with it but get it fixed under the warranty. That is what warranties are for.
