Try running the optical TOSLINK cable from the TV to the receiver. If the TV doen't have a digital optical output, then try going into the menu on your cable box and setting the audio output to the digital optical out. Also check your TV menu and make sure NETCOMMAND is diabled. Some of your newer HDTV have Netcommand that allows the TV to control other devices through the HDMI cable.

I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.

HOW I FIXED MINE:Look through the back vents for a white light to make sure the backlight still works. I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine. I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.

Mine did the same thing where the screen would go black for a few seconds and then the picture and sound came back. I would try (1) switch HDMI cables, (2) try a different HDMI input in the back of the receiver, (3) try different input in the back of the TV. None of these seemed to work with mine. I finally ended up running the cable box direct to the TV and only run the audio through the reciever via coax or digital. No more problems. I think the HDMI inputs in the back of the reciever have a problem continuously carrying the signal if it is the leaset bit weak.

If you are trying to connect it in composite mode (the one yellow video cable) it won't work with the PIP turned on which is how it comes from factory. This is crazy as it means that you cannot see anything (menus) on the screen to disable it. I have a walk through guide here to turn it off blind or the other option is to take the STB and connect it to another TV via Component or HDMI and then turn off the PIP.
