Since you already reset your audio settings, check your source. If you still have issues, you will need a new main board aka A Board

I am getting no sound out of my Panasonic Viera TH-50PX80U Plasma TV


Are the speakers' cables connected correctly? (p. 37) Is "Sound Mute" active? (p. 13) Is the volume set to the minimum? Is "Speaker output" set to "Off"? (p. 22) Change "SAP" settings. (p. 16) Check "HDMI 1 in", "HDMI 2 in" or "HDMI 3 in" settings. (p. 22)
Hope this helps, page# refer to your manual.

My surround sound will not work through the TV, only the DVD


If your tv and surround has an optical input/output.Then you can connect with an optical lead.This will then play the sound from whatever you are watching.You normaly select dig1 or input1 on the surround system.

I have a Panasonic 37 inch Plasma Viera 37PX50U The color has suddenly turned to all green and purple. Would like to reset factory color settings.


Hi dennisreno,
You should be able to set the tv back to factory default settings from the menu.
I will see if I can find the user manual and give exact directions.
Let me know if you find the reset.

Set up the Panasonic SC-PT450 and followed all the various instructions. Am using the surround sound in conjunction with a Panasonic TV bought at same time (50" plasma) but can't seem to get sound out...


Are you sure you're using a source material that is surround sound? Most TV broadcasts are still only stereo.

Also with surround programmes, the rear speakers are only used for the surround effect so will only make sound when the sound source is supposed to be behind you.

You should call for warranty service. If the set is very new try to get it exchanged.

There are some very heavy duty power supplies and many high power matrix drivers used in Plasma sets.

The description sounds like the noises are very loud. It is normal with any of these TV sets, if you put your ear right up to the back of the set at the vent holes you will hear some noises. These would be some acoustic harmonics from the power supplies and related circuits.

I am wondering if it is possible that there is something that is becoming less stable. If the set is working very well without any failure, so-far this is a very good sign. Before it gets to be a problem, I would have this checked.

On many models of these sets, they use fans for cooling specific areas. A bad fan can cause noise.

Surround sound link to new panasonic


The surround sound comes out of the audio out on the rear of your set so the ony leads you need are the Audio set. Red/White, get the lenght you'll need. They get put into the L+R of your audio receiver.

it could have over heated you can try to reset it first unplug it for about five minutes and try to turn it on if that dont work the remote might have a set button try holding that down until the red light flashes twice, then turn it on if not then hold the power button down on the set for a good five seconds to see if that resets it. if none of that works you will have to go to panasonic .com for the reset instructions.with the red light blinking the power supply is most likely good you just need to reset i.
