Question about Panasonic VIERA TH-42PX80B 42 in. Plasma TV

Open Question

My Panasonic Plasma Tv - the HDMI outputs have stopped working - if I choose Sky box, or xbox, I only get a black screen - normal TV and input from PC fine....

I have a Panasonic TH-42PX80B plasma tv - as of about 2 weeks ago, the HDMI ports/output has stopped working - when switch to either of the HDMI's, it's as though the TV doesn't know about the device...screen goes black and never seems to 'detect' either the Sky box, or the xbox360. Normal TV is fine and connecting the PC (via VGA input) is fine. I have run the self-check test, and it would appear to be fine. Can anyone help?

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.

It sounds like you did some good testing by taking your xbox to a friend's home and trying it with his TV and HDMI input. You can try a reset on your Panasonic TV and see if that restores the HDMI input functions. Note this will erase your programmed TV channels so you'd need to re-enter those.

  1. Unplug the TV for at least 15 minutes
  2. Plug it back in and you'll be prompted to go through the initial setup just like when the TV was new.
If after that you still have no HDMI function on any of the inputs, that would indicate the set needs some service by a technician.

Good luck.

How do I connect my sky to tv


Without specifics on your TV or SKY box I can only offer general information. The SKY digital satellite receiver will have a number of outputs for connection to your TV. There will be a co-axial output similar to a TV aerial connection which is for older TVs and most flat screen TVs won't be able to tune into this RF output. There will be a large black rectangular connector which is a SCART connector and this can usually be connected to most flat screen TVs with a suitable SCART lead. There should also be a small connector called a HDMI output which is now the most common way of connecting to flat screen TVs, requiring a HDMI lead. Depending on which method you use to connect to the TV, you then use the TV remote control to select the input you used, which could be listed as SCART, AV1, AV2, HDMI1, HDMI2 etc.

How to connect soundbar to a TV with a skybox


Connect the soundbar either to the TV's optical output. Or use an Optical to stereo phono/RCA converter box and then a pair of stereo phono cables (red & white) to the soundbar.

If it's a very basic soundbar with just a headphone jack input then you can go from the TV's headphone output instead.

As for the Sky box, just leave it connected via either an AV lead or better still a HDMI cable direct to the TV. The TV will send sound out to the soundbar.

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.

PANASONIC HOMETHEATER SYSTEM TO PLASMA TV


Some where on the back, bottom or sides of your plasma tv you will find input jacks for the audio and video. You must know what type of inputs you want to use.
Most have have 4 types

HDMI (audio and video signal combined)
Component (red, blue, green RCA jacks for video only)
Composite (yellow RCA jack for video only)
S-video ( larger round black jack with video only)

The Panasonic should have all of those also. I am certain it has HDMI and Component.

Connect the HDMI cable into the output HDMI jack from the Panasonic into the HDMI input jack on the TV.

Then using your remote for the TV make sure you select the HDMI input for viewing.

If you use any of the other video outputs on the Panasonic just connect it to the same type of input jack on the TV. Once again check the owners manual for more detailed instruction if you need them.

You must always be sure to have the proper input selected on the TV to be able to view it.

You can also respond back with more questions if you have any.
I am happy to help.

Screen flickers on / off when run through receiver


No solution, but I have the same problem with my Panasonic plamsa TH-50PE700U with a Yamaha RX-V2700 receiver. I don't think the cables are a problem. If I turn the TV on and off about 20 times the system stabilizes until I turn it off.
