SOLUTION: Vizio VO420E HDMI Input Not Working
31 Aug
If you have the 42″ Vizio HDTV and the HDMI ports are returning a “No signal” blue screen, use the procedure below:
- Turn off all devices connected to the HDMI ports.
- Turn off TV and unplug from the power outlet
- Press and hold down the Power button on the side of the TV for 30 seconds, then release.
- Together, press and hold down the Volume Down and Input buttons for 15 seconds, then release.
- Power all equipment.
- Plug the TV to the power outlet and power ON.
Hopefully, it works for you because it worked for me. Otherwise, call Vizio and deal with Tech Support.
