sponge14,

You may be in the window to register your television online, and get an additional 3 months coverage for doing so.

My guess is that one of the internal PCB boards is malfunctioning (the panel itself is likely okay). But that's just a shot in the dark as far as "guessing" goes.

Warranty issues are handled on a case-by-case basis through 800-SAMSUNG.

Keep me posted.
