Default Question on audio dropouts with Panasonic Plasma

I have a 6 year old panasonic 42inch plasma viera and recently I have been getting annoying audio dropouts that last about 5 to 10 seconds and then the audio returns. It happens several times in a half hour program.
I have other sets using Comcast that do not have the problem so its not the cable provider. I have checked all set connections and they appear ok.

Any thoughts on what might be responsible and is there a fix short of wasting repair $ on an old set.

It looks like maybe we are having a similar problem. My Panasonic TV is only 3 years old, and for the last year or so we have been getting a 30 second period of garbledsound about 2 hours after we turned it on. Now it seems to happen sooner. It seems to only happen once during an evening of watching TV. Comcast has thoroughly checked it out at least twice. They think it's the TV since they can find nothing wrong with their service. I wonder how long it takes to get an answer here.

No help yet - one responder suggested blowing out the optical ports with a canned duster - but my TV doesn't have optical ports.

So the sound your using is from the TV speakers themselves?Your not running it to a receiver right?
Could just be the speakers themselves ..
Do you have a way of bypassing the TV sound?
Like run an HDMI to a receiver from your cablebox then one to the TV, this could be a way to test it..Plus there is no need for the TV volume to even be used in this set up..

Does this happen with all your devices or just the comcast box.

Have you tried changing HDMI ports ( I'm assuming that's what your using).

Default Question on audio dropouts with Panasonic Plasma

In response to recent posters Show Me Cables and FTM99 - thanks for your suggestions.

I have tried changing the HMDI cable from the Comcast digital HD converter with no improvement. No other TVs in the house are similarly affected and I got a new replacement converter box from Comcast for the Panasonic when I first thought it was the problem. So I am almost certain the problem lies with the audio system in the TV.

I went into the setup for my Panasonic HD TV but could find no way to deactivate the sound system except to select off for the speakers - I don't know it this in fact inactivates the sound system on the TV.
My stereo receiver is old and has only RCA ports for audio input. The converter box has RCA audio outlet port that I can connect to the receiver to confirm that it is the TV audio system and I will give it a try and report back.

Hello again, FTM99. The audio connection from the converter box to the stereo receiver does eliminate the audio dropouts. In fact I tried turning the TV speakers on at the same time and I can tell when those speakers cut out as there is a discernible change in the sound when just the stereo audio system speakers remain on.

That's the good, the bad is that I cannot mute the commercials from my chair as the receiver has no remote control. Can't win them all!

Default audio dropout on audio from hdmi source on th-50px75u

I know this is an old post but i thought I'd take a chance (it's an old TV, after all). I have 4 or 5 second audio dropouts (drops in and out cleanly) on audio from hdmi source on th-50px75u. Happens with my roku stick (2nd gen), fire stick (2nd gen)., or samsung dvd blu ray player. I use HDMI1 input to TV for these.I use HDMI2 for input from my Verizon flos box and I get no audio dropouts. I usually use an hdmi switch to switch between those different sources for input to HDM1 but i pulled out my Roku and connected to straight to HDMI1 and had same dropouts. I have not switched between HDMI and HDMI2 conenctors as they are in back of TV and hard to get to but i will if necessary to test. Any thoughts?
