Question about Panasonic TH-46PZ80 46 in. HDTV-Ready Plasma TV

1 Answer

No picture in HDMI

I have a Panasonic TH-42PZ80U that I bought in Sept 2008. All was well until today. I have sound but no picture. If I go to TV mode, not using the HDMI, I have a picture. But if I use HDMI the screen goes black. I can see the DVR/cable info, menus, etc just not the show I want to watch. Is this a problem with the HDMI cable, the cable signal, or the tv?

After reading tips on this site I did a manual reboot of my cable box. Sure enough, that had been the problem. I'm going to keep a watch on it from now on; if it happens again, I'll call for a new DVR/cable box. Thanks for all the info on this site!

a panasonic tv will shut down after a short time with no video input. it sounds like the setup menu in the receiver has defaulted and needs to be setup again to coordinate the audio and video signals. ive seen many yamaha menus default. dont let geeks in your house.
