Check the 2 main interconnection cables (24pin and 26pin) rear of PDP and Tuner box. Make sure they are firmly connected. (Loose connection of 24pin will cause no power on symptom.)

Hi to all, My 42" Panasonic plasma have the same problem. It turned itself off and now red light flashes 7 times, than after short pause 7 times again. And so on. Any ideas what is wrong??

I had the same problem. You need to go into SETUP > CHANNEL > SKIP and select NO for every channel with a signal. A few months after we purchased the TV it defaulted to this (software glitch). We had lived with it for months before figuring this out. There is no easy way to reset these that I know of. I literally had to go to each channel and then change "skip" to "no." JM

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.

You need to select setup from the TV menu then switch the Viera link on. I think retuning must have switched it off.
This worked for me
