We got the same TV with the same problem. Was told that we had the wall mounts to tight, so we took it off the wall mount and put it on a stand to see if that works, and it didn't. At first we had to wait an hour before we got a full screen, then it never came back. so what did we have to loss! We gave it a good hit on the top back of the TV and the picture came in. We can turn it off now and it works again when you turn it on. Lets see now long this works now. Hope it helps. Never buy a Sanyo again!
