A few months ago I was getting green "swirls" where black should be but I could adjust the picture enough for it to work. Last week, without warning, the screen was totally black with red and green stripes (almost a plaid) and a hiss was audible from the back of the TV. Is this something I can fix without taking to a shop- or is it just shot?
There are some components that have gone bad in the board. It could also be due to moisture inside. Please do not continue to use it and refer it to a qualified service technician.

Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

You may need to set up the video card to see the TV so you can display the computer on it.Somewhere in the setting for your video card should be settings for that.

You have a bad LCD control board going bad,Color getting floresent? Or pixely? esp. when you have it on for a bit. Common prop. But finding parts is a prob.
They are no longer in buis. Try Shop Jimmy,or even Ebay. Encompass does not have any. Runs about 40-60.

If there is still about ? 24. Volts coming from the Power Board when it goes dark, it will be the Inverter board that needs replacing. If not, it is the Power Board that needs replacing. The Voltages should be written next to the sockets & plugs on the Power Board.
