Hi there,

I agree with the above. You will need the main board. I have the boards for this tv if you're interested in purchasing them. My vizio took a remote to the screen. Let me know if i can help. Shoot me an email.

SOURCE: I CAN TURN THE POWER ON. THE SCREEN STAYS BLACK.

This TV has 2 main circuit boards (2 LCD backlight controlers): the Power Supply board may have fried the video board on it's way out ...
You can either arange to have the TV replaced under warenty if not have it serviced. In any case best of luck with Vizio support line.

Everyone bought this TV because it was so cheap... now we find out why: Vizio cuts corners on everything from engineering to support!! All brands are not created equal. Sometimes you get what you pay for.

SOURCE: Hi. My 47" Vizio GV47L

The amber light signals that the power source is in protected mode - the source is practically closed down by force and no longer delivers not even the stand-by voltage to minimally power the processor (hence the remote issue). This happens when one of the other boards in the tv is completely shorted.
Just 2 boards are capable of triggering that when they fail: the power source itself (one of its output transformers or rectifiers have failed) or the inverter/ballast boards (2 of them) - the ones that power the tubes that light up the screen.
To find out which you must disconnect the inverter boards and see if the tv starts up - if the tv starts and you can hear sound (and probably see an image if you light up the screen with a flash light) then the inverter board is faulty and you will have to replace it. If it doesn't then the power board is damaged and the inverter might have caused that - further testing on the components on both boards is needed to determine what caused it. A good experience in repairing electronics is required for that or you will replace boards blindly and hoping for the best

VIZIO GALLEVIA modle VIZIO GV47L FHDTV10A


Most plasma TV's have secoundary power boards, witch can be the cause, now I would try if I where you is to unplug it and let it set a hour or two, if that did not work then the tv will need to be looked at locally. The cause can be a bad power board inside the TV witch is a major cause why a Tv would have a power light put no function at all.

Hope this helps if you have any questions as to what parts to buy www.partstore.com is a best resource.
