Viera TH-46PZ85U. gray box where picture should be

My TV was working fine today until I tried to watch cable after playing a video game. All this entails is unplugging the av cables for the console (completely separate ports than the cable connection), and change inputs on the tv. I did this, got sound and the guide and menus but in place of the picture there's a gray box.
I've tried changing inputs, plugging and unplugging connections... I have no idea what's wrong. I assume it has to be  TV setting since the cable info (guide, channel bar, menus) all show up.

    it's normal. i guess i shouldn't really call it a box it's just like in place of the picture, in between the black bars that change with aspect.

    What happens if you switch back to your game? Does the gray box still appear, or is everything normal?

If it was a setting on the television, then the cable info would also be affected. Try a reset on your cable box, as the cable info is generated within the box from the data stream, whereas the picture is streamed from the provider.

If the reset doesn't work, it's time to call the cable company - it's not a fault with your telly.

I have a Panasonic th-46pz85u. It's been working fine, but now all the hdmi ports have quit working, but the component inputs work fine.


Contact the authorized service center for Panasonic. Please do not make any experiments. The fault is simple now; do not make it irreparable. Surely you can't repair this fault.

There are 6" wide gray bars on each side ot the TV


The grey bars signal that the source image is originally in 4:3 format - if you are using a box of some kind get in its menu and change the format from there to 16:9. The black bars appear when a 16:9 image is sent to a 4:3 format in Letterbox mode - leave it like that or the Pan and Scan mode will chop the sides.

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.
