My tv turns on then shuts off within four seconds vizio 1080P model # E420V0


Sounds like the TV may have something wrong internally. You could try unplugging it for a while and trying again. Other than that I would take it to where ever you bought it and see if they know how to fix it.

TV powers up initially, but shuts down within seconds.


These TV's are somewhat sensitive to internal heat. It appears your sensor has triggered an overheat. This doesnt mean you still have the heat issue, it just saying it needs to be replaced or reset, either way it is not something you can do in your home. Taking it to your local authorized shop will ensure proper repairs, about $90 worth.

Shuts off


From the information you have provided failed capacitors in the power supply is likely causing the problem. The safety circuitry shuts the TV set down when it detects a problem. This model of TV has over 2,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. The repair should cost about $250 if carried into a TV repair shop. A small TV repair shop will often charge less than a large repair facility.

TV shuts off within 5 seconds of turning on


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps
