Many LED TVs and other electronics have bad capacitors on their power supply boards. You can visually inspect them by opening the TV and looking for capacitors with bulging tops. If tou see any, replace them all in the power board section. Check to see if your TV is still under warranty first though.

A possible fix for this Vizio TV?


Sounds like the flash memory has an error for the basic routine on power-up. This could be a faulty program write, error of the bios chip set or a bad memory capacitor if present. I think the cap is there as you have to power the set off for several days so it bleeds off.
Many electronics have a 'house' program for each TV set for the unit to run from start up. Not sure if there is an easy cure as the EEProm may have to be re-flashed. The start up program may have an error and with out a reset button this may have no solution.
I would suggest when it doea power up correctly, power it down and unplug for several days, then restart it.... do this several times and the re-boot may correct the fault.

You will need to get a diagnosis done on the set. It could be a power supply issue or a main board issue. Your problem is between one of those two boards.

Vizio shuts itself off


There may be some components failing in the power supply or one of the circuit boards that are causing too high a current pull.

I realize that this answer is very vague. Without doing proper diagnostics, it is impossible to guess at something like this.

Out of warranty repairs on these sets can be very expensive. I would suggest that if the set is going to be expensive to service, it would be best to replace it with a known brand name that offers an extended warranty with local service. You will pay more, but you will have dependability and better quality.

Pretty good chance the logic board is defective. all remote and manual command go trough the logic board via a micro prosseor. If that is bad the set gets false commands. If the run number is the same on that model they probably all have the same problem.. Get another brand not made in China.
