LEESBURG, FLORIDA -- I bought a TV at store #1241 to use in Florida. I'm in Florida now as of oct 15th and hooked up tv. It work for about 3 mo. and locked up on channel six. Took back to Wal-Mart but warranty 90 day ran out. They gave me phone no. to call, but can never get through. Go to leave message box is aways full. Have been doing this for two weeks now with no success. Also e-mail them with no success, saying will call you back within 48 hrs. So took it to repair shop , they said it would cost 500 dollars to repair. Would like some help to get it fixed or replaced.
