I figured it out myself. R243 was intermittently open. Replaced it, and now we can watch the Super Bowl.

Check the DC filter caps in the power supply first. Check the 24vdc (or 18vdc for this 22" model) to see if it goes away when the screen goes black.
There are main AC fuse, backlight inverter fuses, T-CON fuses.

Do you have backlight? If you do, you have a bad main logic board. Very common with vizio and are hard to find. They are usually out of stock everywhere.

Will a bad power supply board damage a new main board in an led TV?


You can try that without any repercussions except the cost. You need to remember that the LED board has a feedback from the main board that controls the brightness. It would be a good idea to get a schematic and other things before you try this,

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

VX37L Screen Suddenly Went Blank, Now No Image, Sound Only on Cable Input, VIZIO Logo Lights Up


Hello,
turn on the set, grab a bright flash light and dim the lights in the room. Shine the flash light on the screen, if you see a faint picture on the screen, you are dealing with a backlight problem. There are several things that can cause this. One, a bad backlight inverter, two, faulty 24vdc power supply, three, bad main board, or a bad faulty backlamp.
