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.

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.

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. Gopakumar Gopalan Google
I don't know what to do with 10 blinking of my Panasonic TH-46PZ85U. I bought It in summer 2008...is it already kaput ? I'm not sure any more to want to make repair my tv set. I wonder how much could it cost ? Bye-bye plazma.
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.
the blinking light code means that you have a fault in the power supply unit, unplug the tv from the power source, check all transistors you will find some of there shorted, just replace them; if you need a help about repairing i'll help you

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.
