Re: Vizio GV42LHDTV No Digital Channels

Hi all, I'm new at this forum and this is my first post.
I got a GV47L for repair with a power supply issue. After repairing this I detected the same "digital" problem. The demodulator is definitely not the reason. IF out shows changing patterns during scan. Solution is to load up new firmware. Does someone know how to do it?

Thx
