New Panasonic Plasma-color loss when changing station
My new panasonic (equivalent to PZ80U) uses an HDMI input from a digital cable box (with adaptor at box). The picture is excellent(never calibrated). Sometimes when changing a station, the new station will have some pinks and greens but otherwise the picture will be gray. When returning to the prior station, the colors are fully restored, usually. The only method to correct is to turn the set off and turn it back on. Does the TV have a defect? Could the color loss result from a switch from an HD station to a cable, non-digital station? Please advise as the warranty is running. Thanks.

Your problem is in the streaming player. It is not keeping up and when an HDMI loses connection it will not auto find it again. To verify this take the Panasonic out of the loop and see if this fixes it. I love HDMI but it is touchy
Symptom: TV shuts off unless all the input (phono and HDMI) cables are disconnected. The symptom may be intermittent. Cause: There is an abnormal AC voltage entering the TV from one of the input cables or AC outlet. Remedy: Follow the Testing procedure to determine if there is a problem external to the product.
Concept Constant symptom If the TV no longer shuts off when all input cables are disconnected, then one of the input cables is introducing abnormal voltages into the TV. Panasonic Plasma TV sets have 3 wire AC plugs. As a result, abnormal voltages introduced into this TV will cause the TV to shut off for protection. Intermittent symptom If the abnormal input voltage is borderline (marginal), the TV shut off symptom may be intermittent. However the cause may still be detectable with a voltmeter. Protection Proof: Release the protect mode - the TV has to be unplugged to reset this protection circuit.
Threats from the HDMI input: Excessive voltage from an HDMI cable connected product will activate the Plasma TV’s protection circuitry. Placing an isolating / buffering connector (sometimes called a voltage conditioner) between the TV and the HDMI input cable often solves the problem. Testing - Unplug all the HDMI inputs from the TV. Turn on the TV. Plug in the HDMI inputs one at a time. The cable that causes the TV to enter the protection state is connected to the product that has the excessive voltage (and signal). Avoid connecting this product until an isolating connector is found.
As crcelect suggests you can run the TV on RCA. You should also be able to use coax directly from your cable box. If you don't have cable you can use an rf converter to connect coax.
I have exactly the same problem with my Panasonic TH-42PX75U. I've been told that I may need to run a setup on my cable box to fix the problem. If I find a solution I'll provide details in a future post.
The way I solved it was to go into advanced settings and change the audio input connected to the hdmi port to component. I had to run an audio cable from the cable box into the TV but since I did this we haven't had the problem.
Try all of your HDMI inputs, one may be rated at the correct voltage to be able to display the video. The offical part that Panasonic was giving for this was PDPHDMIKIT, its basically a HDMI extender that regulates the voltage. The part is still available online, try partstore.com or andrews-electronics.
Panasonic didn't make it a simple matter to connect a computer to this TV since they didn't include a VGA input connector. You can still do it, but it will require some adapters or changes to your PC.
If you're using a laptop, you have two options. If the laptop offers an s-video output, you can use a suitable cable from there to one of the set's s-video inputs. If there's no s-video output, the other option is to purchase a VGA-to-component breakout cable, available at a number of online vendors (search with Google). This cable has the VGA connector to the computer on one end, and 3 RCA plugs at the other end. You would use this cable into one of the set's component video inputs.
With a desktop PC, you can still use one of those two options. In addition, there may be a DVI video output connector available as well. This is not common on computers with integrated video, but is frequently found on many newer expansion video cards. If your computer has this connector (or you install a new video card with one), you can use a DVI-to-HDMI adapter and connect an HDMI cable to one of the set's HDMI inputs. Many video cards with DVI outputs include one of these adapters already.
So while it's not going to be simple, it's certainly possible to connect your PC to this TV.
Are you using component video cables? If so, check that these aren't loose on either end. Next I'd consider that whatever video cable/input might be bad, and switch cable or cable type... i.e. switch from component to HDMI or vice-versa. Then change up the source (cable box versus DVD player). If you're still seeing blue at this point, the TV internals are the bad.
