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.

Panasonic TH-46PZ85U Plasma TV All 3 HDMI was working fine with cable box, PS3, XBOX360. I used to connect my pc to the tv with a dvi-hdmi cable, but recently unplugged it. So I tried to plug in the same...


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.

Color distortion when playing DVDs


If the player has other outputs try connecting the player to the tv using one of them, ie: use the A/V output instead of HDMI from the player. If the problem goes away there is something wrong with the input on the tv.

HDMI inputs are not working


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.

Audio drop outs when using HDMI connection on new Viera


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.

Sony Viao HDMI to Panasonic Plasma TV HDMI Input handshake


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.

I have only the cable and hdmi hook into my panasonic 42 plasma and i dont get anything that is hdmi is there other cables i need?


Using your input key on the remote should switch you to the other modes. If you cannot access any HDMI or other input labels, go to your menu, and into the Input Labeling menu (under settings) and make sure you have all the inputs you require enabled. Its possible you (or an out of the box error) put these other inputs offline, which is why you aren't able to access your media from HDMI. If all inputs are enabled, and labeled, double check all the HDMI inputs on the unit. Plug what you are using with HDMI into each port, having the power on and sending information to the television. In some rare cases, I've seen that it doesn't allow access to the HDMI without it providing some source information.


Hope that helps.

How to conect a pc to a panasonic plasma th50px75u?


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.

Blue screen


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.
