QUestion on intermittant audio dropouts

by fdm2000 / November 16, 2012 11:59 PM PST

have a Panasonic Plasma TV model TH-42PX50U and lately I have experienced annoying audio dropouts that last up to 5 seconds and then the audio returns.

Anyone out there have an idea what's causing this and should I be considering a replacement?

Just thoughts about it.

1. I've lost count how many times a quick burst of air from a can of air on the optical ports cleared this up.

2. There could be settings and firmware but I'm not going to write a thing since it worked before from what I can tell.

Thanks Bob for your response. Please enlighten this dummy - what are the optical ports?

Here's a video about the usual audio optical ports.

Bob, again thanks for the assistance. I was unfamiliar with optical ports and optical cable. My Panasonic plasma set uses an HDMI connection from the Comcast HDTV digital cable box for combined video and audio. I wonder if I could bypass the internal audio system by connecting to the analogue (RCA) audio out to external speakers and see if that would be a cure? Not sure how that would work with the HDMI connection still in use and necessary for video.

Would appreciate your thoughts.

Keep in mind that

Keep in mind that with another box in play you wonder where the issue is. The usual drop out I see is simply dust in those optical ports or some smudge on the cable end. But you don't use that so it does not apply.

We are seeing dropouts at the source at times so poke around the cable box and see if it can be set to stereo since the TV is just that and anything more can cause odd issues that we can avoid.
