Hi guys. First off thanks to Alex's advice,I emailed RCA. I purchased the Walmart 7 inch tab for my birthday and it quit working two days later. I found this board and got the help I needed so maybe this works for you.
I went to their website, sent a message about the tab, and surprisingly enough, they hit me back. They gave me a repair number, and since I had just bought it, I did not need to provide them with a receipt. I was instructed to mail the tab back (costed me 5.00). I did, and about two weeks later, they sent me a new one. No questions asked.
