Smeared picture in KV-36-HS-20

Hi all,
I am having a similar type of problem. Suddenly the picture in full screen mode and the Left panel (in twin picture mode/PIP) is smeared. The picture on the right panel (in twin picture mode/PIP) is fine. I have tried reset, hard reset, dis-connecting all connections and re-connecting etc. This has not helped resolve the problem.

The picture smear is very easily visible, whenever there is some text in the picture.

Does anybody have any ideas for solving this problem?

Thanks,
Manny
