Contact Samsung service. We had a problem with a larger tube tv a few years back - it was called a 'flat screen" (it was flat in front but stuck out a mile in the rear).
Anyway, it was just out of warranty. Called a service based in Waldorf. Guy came to the house, tested the tv, pulled the electronics tray and took that back to his shop. When it was fixed, he brought the tray back, installed, checked out and we had a brand new tv for $200 I want to say.
Apologize, can't remember the name, nor can I find a receipt.
But I know Samsung will send out repair people
If not Samsung, check with Best Buy - Geek Squad.
