RCA flat panel L42FHD37 When first turned on no sound but picture. Hooked through HDMI1 port from dish network satellite. If after turned on go to HDMI2 then back to HDMI1 the sound magically...


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.

You can try unpluging the power and let the tv reset. Or call for service, it's still under full warranty.
