TV had been working just fine, hooked up to Comcast cable box. Had to move furniture & all was unplugged a few days. TV worked when hooked up again. Turned it off & 1 hr later turned it on & all was OK. After 1 hr TV turned off by itself; we can't get it to power on for days no matter what we do. Power source OK. Plugged into different outlet, no help. Unplugged TV & pushed power button on TV for 30 sec, no help. TV acting like it's dead but we don't think it is.

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

It is the electrolytic capacitors on the power supply board gone bad. It is fairly simple to remove the board. Look at it this way. Even if you break it taking it out, you would have thrown away the vcr anyway. I simply experimented with mine and it payed off. I just replaced mine in the exact same model vcr you have(slv-690hf). The vcr would not power up. I replaced c202, c207, c109, and c208 and it works perfect again. They are the smallest ones. I'm pretty sure it was only one that was bad, but i replaced four of them just to make sure i got the bad one. You cannot tell by looking at them that they are bad. I just searched the internet and read where it's usually the smallest electrolytic capacitors on the power supply board in sony vcrs, that usually go bad. Sure enough, that was the problem. It is fairly simple to take the board out and do it, if you have time, patience, a little bit of know how, and a soldering iron. I used some capacitors from radio shack and some out of an old stereo crossover i had that did'nt work for the replacements. The capacitors from radio shack have a wire coming out of each end instead of both coming out of the same end. I just simply bent one wire over the top to make it work and cut them the same leangth. Be sure you use the same uf and voltage for the replacements.

This sounds like the main power board went bad. If this is still under warranty, contact 1-877-MYVIZIO and they will have it repaired for you. if not, let me know and I will guide you to the right part.
