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.

SOURCE: My Vizio remote doesn't work...
I know that on the Logitech Harmony Remotes, sometimes the infrared LED emitters go bad. Perhaps that is what is happening to your Vizio remote. If everything was working just fine but now none of the buttons work, it is probably your issue. You can test to see if the LED(s) are working by using a digital camera (or cell phone camera). Here is link that describes how to test to see if your IR emitters are working. Although you have a different model, you may be able to pick up a few tips from this article. Good luck!

SOURCE: VIZIO GV42LHDTV Got TV after
If the TV does not start with the new audio board, and if it does start with the old one, then the audio board that you recently purchased is defective.
About the board : 0500-0507-0230; that is the power board (PSU). If you could see the Vizio logo, that means that TV started, and that the power board was OK without need for testing. When the power board is defective, either the TV does not give any sign of life, or the TV goes in standby mode from start and does not wake up. In that case the led stays blinking to warn you that there is an incorrect voltage from PSU.
If the TV is freezing with Vizio logo, that means that at most the faulty part is the main board.
Also, you say that there is no backlight. No backlight means that the screen is completely dark. If there is no backlight you won't be able to see the logo or any other picture.If there is no backlight, then the problem is usually the inverter.
Here a brief article summarizing how to test PSU and inverter: How to test an LCD TV.
Here all parts for this model:GV42LHDTV.
