I went to turn on my Vizio and the scrren was

Do you have back light when turning on the TV? if you do then just replace the main board should resolve the problem. if you do not have back light, you will need to replace the inverter board(s) depending on your model. The inverter board(s) is located on the left side of the TV facing back of TV. you may have two inverter boards depending on your model. the other is located on the right side of the TV. Both mount vertically.

Tech Guy-925 Hi Dave,


I have a Vizio VW37L hdtv20a. My kids use it for there Xbox360 and they leave it on all the time with the blue screen showing for hrs at a time. So when they told me it does work anymore I thought they finally burnt the mainboard or powersupply. I have the same issue with the Vizio going from Amber to White with no picture/sound just black screen and the side control panel to select power and menu does not work also.
My Solution:
1) I tried to hold the power button down while pluging it back in and waiting for the screen to change to blue and it but it when back off and did not turn back on using the power button or remote.
2) I used the remote this time holding down the power button on the remote and plugging in the TV. I held the button down until the Vizio lite went from Amber to White to Amber again. I let the power button go and pressed it again and the TV came on and the side control panel works also. I turned the TV on/off a few times using the remote and side control panel and all seems fine now.

Thanks,
