I was having same problem, and think I got lucky and found fix.
Try unplugging the TV and waiting 30 seconds, then plug back in.
You will likely get blue screen with "No Signal".
Go to Menu, then scroll down to "Setup". Select "Factory Reset" then hit "Yes."
This did it for me. Wish you all luck.

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.

The CS800 designs have not changed mucch in the last 20+ years. There is a resistor inside that can fail that can cause this symptom. If you have not worked on these before, I'd suggest that you have this serviced. As it stands the parts cost should be in the $20 range. If the outputs have finally failed, the parts cost will go up significantly. WIthout taking measurements inside the unit, I can't say specifically what is wrong.
Hope this helps,

SOURCE: Left Channel does not work
Sort of sounds like there's a PC in the mix.
Can you swap the left and right speakers to isolate the speaker from the source as the problem?
Have you tried switching the various plugs around to isolate if anything comes out to the Left Channel, ever or if any other speaker plugged in as the Left works at all? Turn the volume down and bring it up slowly at first because if you send Subwoofer programming to a speaker not designed for it you may damage it.
If nothing works when plugged in as the Left speaker, maybe the sound card is the problem. Resubmit a question with the source or the PC as the problem
