It may be a faulty component on the power supply board. Check the electrolytic capacitors on the power supply to see if any have domed/bulging tops.

This is usually down to a safety feature cutting out the Television from harming itself. Or quite possibly a fault that make it turn itself off - it may well be thinking it's receiving the command to turn itself off. Either way, it's impossible to find out without opening it up. A professional repair is the only way, check up on your warranty. You may want to plug it into a different power source, just on the off-chance that it may solve your problem - but don't get your hopes up.

SOURCE: no video, shuts off then back on

I checked Toshiba's website and found the manual for the set. The self restarting was indicitive of a lamp failure. The red light was solid while the green light blinked. It would then restart 8 times before both lights would then begin blinking.

this could be one of two problem. first, check if you have back light. If you do then the problem is with the M/B. Second, if you don't have back light then the inverter is bad and needs to be replace.

Vizio tv repair picture blurs and darkens for five seconds and then goes normal for five seconds and continues this cycle. i changed the tcon board and no change.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

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.

No Power


It appears that the power supply is starting to fail. It is also possible that there is another board in the set that is over-loading the supply.

The nature of the fault indicates the strong possibility that there are some parts that have become thermo sensitive. This is not a reset problem going by your description. Unplugging the set, is allowing the boards to cool down, and therefore they will work for a while until the thermo sensitive parts heat up again.
