Question about Panasonic Viera TH-50PZ80U Plasma TV
When my panasonic viera turns on, the channel information in the upper left hand corner keeps flashing and there is no picture. I think it could be a problem with overheating.
I had this exact same issue just yesterday. Channel info would flash
intermittently. While set was in this mode, could not enter menu,
change channels, etc. from remote or front panel controls. Similar to tjh492, I thought it might be an
overheating issue. But unplugging the Viera and waiting for set to cool
made no difference.
I then remembered that this issue popped up the instance I surfed to a particular channel (FWIW, 26-3 "Me Too" on Comcast here in Aurora, Illinois, USA). I had a hunch that there might be an issue with the signal on the channel that prevented the Viera from properly syncing, so I decided to unplug the antenna cable. Once I did that, the channel info displayed steady. I was then able to change channels (of course screen was blank as antenna cable was unplugged) and enter the Viera menu. I immediately went to channel set-up and manually removed channel 26-3 from the channel list. After reconnecting cable, Viera was back to normal. Since I'm not a big fan of "Me Too", problem solved :)
Not sure why a digital channel sync issue would effectively make the Viera remote and front panel controls inoperable. Pure speculation, but it could be that the Viera microprocessor was overloaded trying to sync to channel and this prevented any interrupts from remote or front panel controls.
