    Vizio M65-C1 intermittent half screen outage

    I have a Vizio M65-C1 that intermittently loses the video on half of the screen (see pic). When first turned on, the TV works fine, but after a while the right half of the screen becomes a flickering, jumbled mess of lines. After a bit the TV usually restarts and works fine for a bit longer. I'm wondering whether anyone can tell me if the problem is the Main Board or the T-Con (?). A clue is that the main board heat sink becomes very, very hot. The two large ICs on the T-Con get pretty warm, but not alarmingly so. Thanks.

    This is a a signature main board issue. Common failure for these main boards. We see this with the P502ui-B1 P552ui-B2 P652ui-B2 often as well.
