Question about Vizio Televison & Video

Open Question

My 70 inch LED Vizio TV (E701i-A3E) turns on but no picture and no sound. It seems to have a backlight. After a minute or so it turns off completely by itself. What board should I replace?

    This TV uses a sharp LED panel, it is a common problem with this model. If you still have the purchase receipt, please contact Vizio, they will ship you a new TV (They extended the warranty due to a class action lawsuit).

Does LCD screen backlight come on? If so proceed....
USE:CAUTION WHEN DOING THIS....
Try this if repairing yourself...find power supply, small board with no cover over it...check voltages on output pins/plug/connectors (white plugs) three in a row...
1 Plug has 24Volt supply..1 has 12Volt supply and 1 has 5Volt supply when read to ground (screw that holds board in) if you have these voltages it's a safe bet it's the main control board...I just replaced mine and it fixed a problem like yours.

Do you have backlight? If you do, you have a bad main logic board. Very common with vizio and are hard to find. They are usually out of stock everywhere.

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.

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.

Replaced all 3 boards in ViZio E701i. Backlite comes on & set immediately shuts off.


I would claim the 180 day warranty on the parts you got. Chances are one of them are defective. It's rare that the display or backlighting shorts out and causes shut down of the system.

By the way, you put this in the Wall Mount category not TV's,
