Re: Vizio GV42LHDTV No Digital Channels



Yeah, It's definitely a strange one. I saw your posts before when I first starting researching this problem. Was wishing that you had solved it. I'm going to look further into the power supply, there may be some ripple voltage causing the problem....

I may very well have 2 good boards here....
