SOURCE: My vizio e420vl turned itself
There are at least two power supplies in any set with remote capabilities; one is on any time the set is plugged into AC and is supplying that indicator and the receiving circuit of the remote, otherwise it wouldn't turn on under normal conditions. The second power supply produces the needed service voltages used when the set is in use. This second supply is a common failure in many sets and it is generally traceable to poor design and the use of low-quality components of a certain type. Vizio may have a repair or exchange program through their service center. I would guess the cost will be between $50-$150 and you might remove the back panel of the set and look for a smaller board with larger-than-average parts on it and is related to the AC cord coming in. It should be fairly easy to remove and replace as these are often outsourced and just plugged into the rest of the set with dissimilar plugs making it simple to install and reinstall.

That problem is usually cause of faulty capacitors on the power supply board..
Just follow this instruction to fix your TV..
1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter
