Orange light stays on. like in stand by mode, all fuses good. nothing on the boards looks bad, just wont power up
I would double check the capacitors on the power supply board. Make sure you don't have any that are bulged at the tops. Secondly, when you try and turn it on, does the orange light flash at all??

possibly is the main board.

Does LCD screen backlight come on? If so proceed....
USE:CAUTION WHEN DOING THIS....
Try this if repairing yourself...find power supply, small board with no cover over it...check voltages on output pins/plug/connectors (white plugs) three in a row...
1 Plug has 24Volt supply..1 has 12Volt supply and 1 has 5Volt supply when read to ground (screw that holds board in) if you have these voltages it's a safe bet it's the main control board...I just replaced mine and it fixed a problem like yours.

Does the remote have one power button for on/off .... or, does it have separate buttons ?
SOURCE: my vizio vw42l no picture,no sound , the power
Yes, changing the main board should correct the problem.
SOURCE: My componet/av only shows black and white on my vizio vp422
The 37" Vizio I just bought has a very confusing feature where the same input can be used as either the Y channel of the component or the full video channel for composite. If you plug a component source into the TV and then select the composite input ("AV" on the remote), you will see a black and white version of the full component signal (makes sense as the Y channel is just the luminance component). As sad as it is, I was stumped by this for a while until I happened to hit "COMP" and got full color. FWIW, the manual warns about this, but it really doesn't emphasize the point. I wonder how many returns they get because of this.
