May be a bad power supply, which is a common problem with these units.I have a GV42L 42" manufactured in march 2007. It works perfect except the screen has a fracture on it. The warranty is voided because we damaged the screen. I can sell this to somone who has a good screen but needs boards or speakers, etc. Or I will buy your tv that has a good screen but damaged boards in it.

The main board has failed. Replace the main board will fix the problem.
By the way, where did you buy the TV? If you have bought it from Costco then try to give them a call to see if it still under warranty.
Hope this will help.

there are several possibilities. first if the unit comes on and the "VIZIO" light turns white, but no picture or sound, then the main control board is most likely the issue. could be the LCD control board(s) depending on model one or two. and ultimately could be the power supply on the upper side....if the "VIZIO" light does NOT turn white, the whole power supply unit is out. after that, would have to scope the circuits to find out. Seems that the control board is the most common and tends to happen on many different sizes. new board will be around $350.00. Might get lucky and find a used one, but it MUST be EXACT part or it wont work right. if you dont find one or want to sell yours for parts, id be interested in the screen. can reach me at email@example.com. thanks, keith
