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.

SOURCE: 32" vizio won't turn on
Hello; I am John at J D Electronics in Poland, Maine. I have now repaired 81 of this same model in my shop or PCB mail in's. The set may be dead always or work intermittently. There are 2 versions of this piece of junk, but I have only seen this one. They all have 2 to 7 capacitors that fail on the power supply board that are just above that red chopper transformer. The are labeled C233 and C234 and others. These first 2 are 3300 ufd at 10 volts and 105 C temp rating. You can buy these for about $1 each from Digi-Key Electronics plus $12 shipping. There are some cautions worth mentioning. Make sure the set has been unplugged for a day or more before starting the disassembling. It is VERY important to keep the set face down on a soft surface when doing ANY work on the set. This crappy designed set has a glass faceplate that will fall down if you don't have it face down when all the back screws are removed and it is very hard to put it back into position if it falls. The bottom plastic speaker strip has a million screws to remove both from the bottom edge. Then take out all the screws for the metal back and unplug the speakers. The connector wires to the speakers will not just pull off without you pressing on a side release pin for each of the 4 wire- Stupid design again!. If you are not able to solder or test these caps , you can send the board to me with $46.00 to replace and/or test up to 7 caps this includes USPS Parcel Post return shipping. I accept only cash or USA postal MO. There is NO Warranty on this repair. It is a better than 80% chance this will fix your set. You must call me first at 207 998 5687 EST 9-5 only. Good Luck! John
