When I try to turn it on nothing happens. No click, no flash (NOTHING). Tried using remote and the side button and nothing. I bought it on 11/25/11 on black Friday at Walmart. Tech support says it is covered under warranty and did not ask if I still had a receipt. (I can't find it, I think my dog Sheldon ate it) They scheduled a tech to call me to schedule an appointment. Has anyone else had powering problems and do repair men ask to see the receipts?
