Display IC seems to have gone. It will be a replaceable module. Only you have to figure out which one it is. Such thing happen in electronics. Look for any burnt or bulged IC.

Either the convergence or cracked sautering. Just had my tv repaired but now I have a double blur in the upper left corner.

You have the picture in picture on and the second picture is black because there is no input source plugged into the second input.

In your manual, look up the picture in picture functions and how to control them. you should also be able to change that second picture to see the main feed and swap between them.

Good Luck,

No, if the picture of your tv screen is clear when when you watching. the troble of your tv is looseboard, and you replace your CRT socket too.

Needs Hyper board repair = replace bad caps
PCB not available to buy outright........................T.

Possibly Replace Attenna CABLE

I had this problem around the time my TV was 3 years old. I ended up having to get it repaired at a TV repair place, it cost me $375.

Same thing happened with us, the onscreen display button unlocks the tv, goodluck
