In the "misery loves company" category, here is my experience. In March, 2010, I replaced a 40 inch LCD TV with a Toshiba 46XV645U. I have a Scientific American 4250 HDC Cable box and a Sony DVD player connected to an Onkyo TX-SR606 receiver, which I had been using flawlessly for a few years. All connections are HDMI, and all signals go through the Onkyo. Almost immediately after installing it, I began experiencing spontaneous shut-off of the TV. I called Toshiba and set up an in-house service call. Throughout the intervening months, a technician replaced the TV's main board, the power supply, and the wireless remote sensor. Nothing fixed the problem. After Toshiba declared the issue to be something "external" to the TV, and therefore not their responsibility, I began, by process of elimination, trying to determine the culprit. The TV itself would stay on indefinitely if the other components were off. It wasn't the TV independently, so there must be a conflict. My final conclusion: it's definitely the Onkyo. What to do next is the burning question. It's been ten months of frustration. The TV still turns off in the first couple hours of use. I'll post again if I come up with a solution, short of a new receiver. This thread has been enlightening. Thanks!
