Question about Vizio Televison & Video
This is a common problem on this set.First make sure to hit the menu button on the TV's remote and if nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your backlight is not working. You can also check the transformers they are close to were the wires plug into the panel, make sure all transformers read the same amount of resistance if not you have found a bad one. Now you will have to check to see if the power supply is sending 24v to the backlight, if not the power supply is bad. Cost backlights around 150.00 and power supplies around 100.00. Well this should help you friend.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

Thanks for using FixYa. To check what has gone bad you’ll have to open the back of the unit and check the backlight inverter board. The inverter is the power supply source for the backlights. If that’s the issue then it’s always better to replace the inverter board completely just to avoid any future issues. If not then check the power supply board however, it seems to be the inverter board as the sound was still working fine. Please do accept the solution if the issue is resolved or post a comment for further assistance.
