You can easily fix this audio problem by downloading a software upgrade for your HDTV. And you don't have to be a rocket scientist or a brain surgeon either ;)
If you need to find the software upgrade:
Go to RCA.com and click on Support, from there you will click technical support. In technical support, click on the link called Software Download. Scroll to the bottom of the page where you will find 2 links. The first link will tell you how to download the software to a Mini Cruzer USB drive (you need at least 15MB of space) and the second link is the software download itself.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

It's likely not a backlight, but a mainboard. If you are feeling frisky, take the back off and get the model number off the mainboard and check eBay.

This may work for you. My Vizio went black except for the blue channel rectangle in upper right corner; I couldn't change the channels or power off. I called Vizio, was told I needed a hard reset, and this fixed my problem: I unplugged the TV; held down the on button for one minute, then plugged it back in. It works fine now.
