Question about Panasonic TH-42PD50U 42 in. Plasma EDTV
When turn on tv the red indicator light goes on and then flashes - no picture
I just had this same problem and Panasonic says that it shuts down due to incompatibilities with a PC signal and HDMI 1 and 2. HDMI 3 is designed to work with a PC. If you unplug your HDMI and turn the TV off and then back on, it'll work. You can then plug your HDMI back in.
Or, you can just use HDMI 3 and the problem shouldn't happen again.

I just bought a Panasonic TH-42PZ800U and had the same problem. 10
blinks and the TV would not start. Then after some trial and error I
solved the problem!
Here is my (apparent) observation and solution:
I had only one input into the TV, which was my HTPC connected via a DVI-to-HDMI cable plugged into the Panny's HDMI 1 slot. *IF* the HTPC was already on, then the Panny would have the blink of death. *BUT* if the HTPC was off, the Panny booted fine (assuming I cleared the blink of death first by powering off the HTPC, unplugging the TV, and replugging the TV back in with the HTPC still off).
My solution was to move the HDMI cable from slot 1 to slot 3. After making this one change, everything worked as it should. No more 10 blinks of death. I could even leave the HTPC on and turn on the TV last, and it still worked. Tried this 10 times, worked 10 times.
I don't know if this will solve other people's problems, but I hope it at least provides some clues. I wonder if this is a fundamental circuit design flaw on the part of Panasonic, rather than a "bad batch of parts" problem.
