Without a specific model it is hard to say how to reset it. It will most likely involve holding down the power button (while it's already off) and menu or mute (can't remember exactly).

Try unplugging the set for a few minutes then plugging it back in. But as mentioned, without the specific model number I cannot say for sure. Check the owner's manual.

Try doing a factory reset.

Press and hold the "VOL -" button on the TV itself and the MENU button on the remote, both for 5 seconds. The "Self Check" screen should appear. Now press and hold the POWER button on the front of the TV until the TV powers down. TV will restart and you should be good to go.

I don't have my remote, is there a hard(factory) reset without it? My 50" plamsa Viera is All Red! What happened?

pmccartt, did you try a089300's method?

Your instructions worked for my TV many thanks

Pressing the volume minus button on the TV and menu button on sky remote for 5 seconds worked for me

I have a Panasonic viera TV And has the hdmi blocked. I can not use the cable box neither the ps3. I tried already resetting TV, I disconnected everything And nothing happened. The Message I get is this "DVI Alert... The hdmi is blocked... your hdtv does not support hdcp... use your yprpb conectors.

Helo please..

Did you try The Component(yprpb)which consist of Red, blue, and a green for the video. And a red and white for audio?
What cable are you using for the 2 components you mention, anything else?
