Question about Vizio E421VA 42 in. LCD TV
After about 3 hrs of operation, volume goes us, 30 sec later, picture freezes, 10 sec later the tv reboots, is it a power supply problem?
Sounds like a surge to me. Why not give Vizo call to see if anyone else is reporting the same problems. It's a fantastic tv.

You my have a bad capacitor. I had a similar problem with my 42 in Phillips. I did some research and found that a lot of electronic devices made only a few years ago were having all sorts of problems because of capacitors. They fail after 2-4 years due to a lack of preservative. If its still under warranty no big deal. If you are not, you might look into getting a new Power Supply Board.
If you are willing to open your TV up and take a look at the capacitors on the PSB(the board that the power cord comes into) you may find your problem. Blown capacitors look bulged or leak. sometimes they show no sign of a problem but if there are any visible signs you know for sure.
They are replaceable but it takes a few soldering skills.

If you can get into the setup program, try doing a factory reset to get back to the default setup settings. This may cause you to lose apps that you have added to the set, however, but that's better than having to buy a whole new set. You also may want to see if there are any updates for the set from Visio if you don't have it set up to download and install them automatically already.
