After some looking I ran across several other people that had the same issues and replaced the main and power supply board but no change. If you leave the tcon cable unplugged to the right side the tv responds normally to the remote and has sound in between the reboots. One person said that they found that if they plugged the tcon cable into the main board after it was on they got a perfect...

Looking forward to learning a lot here. Thanks for letting me join!
