Vizio L32 hdtv10a..

My tv won't turn on. The orange light is on - will not turn green and go on. Have tried disconnecting from power, using remote, manually hitting on button.

I ordered and replaced the main board part 3632 0012 0395.... and nothing.. Screen is still black. Do I need to reset anything?

Could it be the inverter? If so which one main or slave

    If the light on the front of the TV supposed to turn blue when the TV is operating normally, the amber light indicates that there is a problem inside the TV circuitry.

    In any case if the back light inverter is the problem, the TV will still show the blue light but no video. The video will be in the screen background very dark and to be able to see it, you might have to shine the light from a flash light near the screen and look at the screen from a 45 degrees angle. If you have a dark video, then is your main back light inverter board is defective.

My VIZIO vx32L/hdtv10a remote only lets me change channels. No volume up/down or power on/off function either


If your audio is being routed through a home theater system then you will not get vol control through the remote for the TV. You will have to use the home theater remote.

Vizio TV 2006 vx32Lhdtv doesnt work.


I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.

HOW I FIXED MINE:Look through the back vents for a white light to make sure the backlight still works. I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine. I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.

Look at the power supply, look for burnt parts, bad capacitors, etc.

Please post back what you find.
I have the same model for my bed room, my power supply blew up beyond repair, had to buy a used one, now the LCD controller board is going bad when it gets hot. Not a very good TV.
