LCD Turns off or screen goes blue

The LCD just turns off and the green light in the power supply turns off. After tapping the supply the screen comes back on. Also the screen goes blue and cycling the mode from VGA-TV COMP will get it back on.

A new supply cost $125 and I would hate for it to be something else.

Help before I order the supply, I know its a gamble.

Re: LCD Turns off or screen goes blue

I had the same problem with mine. I replaced the power supply and the problem was solved. That was about two months ago. Now I have the problem with a very brief blue screen, then going black with the sound still working. From what I have been able to find out it appears now that I have a bad power inverter. I will be replacing that next.

Does anyone have a problem with the screen looking cloudy? When my TV was working, I could see areas that looked like faint black clouds across the screen.

Why did it work before installation, now flashes numerous different colors?

Before installing replacement parts???

I can assume that the t-con board or the video board had terminal connectors or ribbon connectors. What is often overlooked is a misaligned connector or worse, a broken or bent pin. Try examining these connection points. You may have to use a magnifying glass. A defective screen usually goes black or produces broken images and/or color points.
I hope this helps.
