Thank you, Jam!
One more question please: When I first turn on the TV each day that red light stays on and nothing happens. When I try a second time the TV then goes on (and the red light goes off).
I've tried this with 3 remotes (2 Samsungs, and one from the cable company).
I've tried Resetting to Factory Deafults to no effect.
I'm concerned that after Warranty things might get worse.
