Hello and thank you for the question.

When you say it's turning on only, does the screen backlight, and do you get the Vizio logo on the screen for a second or two?

If you press MENU, will MENU show on the screen?

no and no

Expert:  Aric replied 10 months ago.
Thank you for the reply.

There was three questions actually, so when you say the TV is "turning on" what indicator do you have the set is on?

Customer: replied 10 months ago.


only the green light at the bottom right

Expert:  Aric replied 10 months ago.
Thank you Brian.


This problem can be caused by one of several things.

Let's try a hard reboot of the TV. Please disconnect the set from power, then press and hold the touch sensitive power button on the TV itself for 10 seconds. Then plug the set back in and press power once.

Let me know what happens.
Customer: replied 10 months ago.


ok where is the touch button?

Expert:  Aric replied 10 months ago.
The power button on the TV Bryan.
Customer: replied 10 months ago.

ok. it wont turn off and when I unplug it the light turns yellow

Expert:  Aric replied 10 months ago.
If you're unplugging the actual TV itself (not the cable box), then light will go out, give it a few seconds.
Customer: replied 10 months ago.


I do and after everything is off I hold the power button for 10 seconds the then I turn it back on and the light turns green with a soft thump through the speakers. The screen is still black. I am not hooked up to the cable right now.

Expert:  Aric replied 10 months ago.
Okay, you don't have to be hooked up to the cable- simply press MENU, Input, or Volume on the TV, or original TV remote and let me know if anything at all shows up on the screen.

nothing not even the no signal words

Expert:  Aric replied 10 months ago.

Thank you for the reply.

 


Unfortunately, the Mainboard, or the Power Supply output to the Mainboard on your set has failed. They work in tandem to allow the set to turn on, the Power Supply provides the voltages to various circuits in the TV, and the Mainboard contains much of the communication required for the Power Supply to turn on. The power supply is the board that the AC cord connects to inside the TV.

 

Often times, one or more capacitors on this board fail, and will give you these symptoms. The Mainboard is the board directly mounted to the rear panel of the set, that routes and processes all of the AV signals to the TV. This is a common mode of failure for these sets. Average cost or this type of repair is around $250-$300 parts and labor.

 

 

There is no reset or series of buttons you can press to fix this problem, and the set will require service.
