If you have a bit of knowledge, you can open your Vizio TV and get to the motherboard. Search these for popped capacitors, and they will have a bulging top instead of a flat one. Replace these capacitors. Find the ones with the same voltage from the shop.

You can call Vizio Support for more guidelines.

Checking the T-CON (Timing Control) board can be another potential fix for resolving green screen issues on a Vizio TV. The T-CON board is responsible for controlling the timing and processing of the video signal.

  1. Turn off your Vizio TV and unplug it from the power source for safety.
  2. Locate the T-CON board on the back of the TV. It is usually situated at the center or near the display panel. Refer to your TV’s user manual or consult Vizio’s support documentation for the exact location.
  3. Carefully inspect the T-CON board for any visible signs of damage, such as burnt components, loose connections, or bulging capacitors.
  4. If you notice any physical damage or suspect an issue with the T-CON board, you may need to replace it. Contact Vizio customer support or a qualified technician to obtain a compatible replacement T-CON board and for assistance with the replacement process.
