Vizio VL470M won't turn on

Watched tv last night everything was fine. Tried to turn on this morning and could not power up with remote or side panel power button. The Vizio label is lit amber so there is power applied. I have tried unplugging the power cable hoping for a reset with no change in symptoms. I also disconnected the HDMI cable, no change. Any help is greatly appreciated.

    I have the tv connected to a surge protector and al other devices have normal power. I have also verified there is 120V at the end of the cord going to the tv.

See this instruction: God bless you

  1. Check if the power cord has been properly connected to the power outlet.
  2. Check if the main power has been switched on.
    (DVD player's power supply transformer could be burned out)
3. test the power outlet wall see the diagram
4. do not use the r.control use the power button directly from TV.

    test the power switch for faulty or dirty, or loose wire inside. Otherwise you have problem with the power supply see the diagram attached

    The diagram is very small and hard to read. I did find that one of the cats had been chewing on the hdmi and power cable. I ohm'd out the power cable and did not find any shorts, however the hdmi cable looked pretty bad. My thought is that if it was video related I would just loose video and still have the ability to power on the tv, your thoughts? I read on one of the other posts that there is possibly some fuses located inside the tv? Thanks again for your assistance.

For the 46" TV, it sounds like the main board is bad.

For the 50" Vizio: is the LED light on?

My tv [vizio vf550m] won't respond to a remote.


Vizio is famous for having main board issues. If you have replaced the IR board the only two other items it could be is a broken wire from the IR to main or the main board has an issue. Nothing else can stop the remote from working provided the remote is working properly.

Tv wont turn on worked fine last night


If there is no power at all, then the problem is likely the power supply unit.
The PSU must be tested, then eventually replaced.
