Contacted Vizio, reported that there was a loud crack and flash accross the middle of the screen thent the screen went black. Vizio person told me it was most likely the power supply.

It is very easy to replace the power supply.

- Remove the stand
- Remove the speaker
- Remove the back cover.
- Remove 4 wires connector on the psu.
- Remove the 6 screws on the power supply and replace it with a new one.

Hope it will help.

I have a Vizio model E320Vl TV. after working for about two hours it shuts off. You can unplug it and wait about 10 minutes and it turns back on but will shut off again after awhile.


Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
