Although taking apart your 42-inch VIZIO television is usually a job left to television repair professional, you can attempt to repair the television yourself. However, removing the back panel of your VIZIO television will void the 10-year warranty. Commonly replaceable parts include the LCD inverter, control board, transformer and speaker assembly.
Instructions
1. Unplug your television and lay it screen-side down on a blanket to protect the screen.
2. Remove the screws surrounding the back casing using a Phillips screwdriver. The number of screws varies depending on the model of your television.
3. Pull the base out of the television if installed.
4. Lift the back cover off of the television. If you meet resistance, make sure that all of the screw are removed. Use care around the audio/video connections.
5. Locate the part that needs to be removed. Disconnect the wires connecting the part to the power supply. You may need to remove tape that is securing the wires.
6. Carefully unlock the ribbon cable locks. These locks are delicate and break easily. Gently tub on the connector of the ribbon cable to remove the cable.
7. Unscrew the screws holding the part into place using a Phillips screwdriver and lift the part out of the television casing.
