Facing TV Problems? Ask a TV Technician.
Hello, Sorry you're having problems.
The picture flipped over and over could be as much the fault of the DirecTv Box, as it could the TV. That said, further testing is needed to conclude that. What I would need to know is this:
When the picture starts flipped, if you grab the original Vizio remote and press MENU, does the set's own MENU remain stable and solid please?
Also, what promoted DirecTv to conclude that the issue was not with their box?
Please review my reply and post one back to proceed.
