Question about Flat Panel Televisions
TV runs fine for 5-10 minutes then picture freezes but sound continues. The remote stops working as well. When I turn the TV off and then back on the TV works again for another 5-10 minutes before freezing again. I am using a DTV antenna.
i've just some digging around and found that you can access a service menu and perform a reset which sorted the issue for me.
Access the service menu by pressing, in order, whilst the tv is in stand-by mode:
when the tv comes back on you will have a service menu; select option 12 (reset) the tv will then switch off.
this will reset your TV back to factory defaults.
turn tv back on and you should be prompted to go through the plug and play setup again - go through everything and then all should start working OK (it did for me)

Hello, This seems more like an interface problem then a board issue. Which interface are you using Component Video, HDMI or , RF(F Connector)? If you are using the RF (F Connector) there might be a problem in the tuner including the RF and IF sections on the circuit board. If you are using HDMI there might be a problem in the HDMI Integrated Circuit If you are using componente video the there might be a problem in the video circuits connected to the RCA jacks of the Component video input. If I were you I would have the take the TV back to the shop and have these items checked out, because board swapping is not the proper thing to do. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

The main board for this unit seems to be defective. The part number for this model is: 3320-0032-0150. Encompass has it new for $180.00+shipping. It will be a good idea to veryfy that this is the right part number, cause I have seen vizios with the same model number to have diferent main boards. Good luck.
