How to Check the Power Board on a Vizio TV

By Ron Roberts

Every flat screen TV has a power board where the AC plug fits in. When the power board fails in a Vizio TV, it is unable to transfer the electrical current throughout the TV. This can also be caused by a blown fuse or transformer, and all of these items should be checked first. These tasks are an easier, more economical repair than replacing the power board on a Vizio TV.

Things You'll Need

  • Screwdrivers

Step 1

Place a towel or other soft cloth on a surface to protect the Vizio screen.

Step 2

Lay the Vizio LCD face down on the prepared surface, and remove all the rear screws using a screwdriver.

Step 3

Locate and visually check all the fuses on the Vizio TV. There are likely five fuses.

Step 4

Replace any spent fuses. If the TV picture still does not appear, remove the existing power board with a screwdriver.

Step 5

Remove any wires or cables that connect to the power board, and replace the power board with a new power board. Note the model of your Vizio TV to ensure getting the correct power board replacement.

Tips & Warnings

  • Always check fuses and transformers before centering in on the Vizio power board.
