Model DS20425
Chassis 20425-05

Picked this up curbside the other day.

Picture quality is excellent.
Audio has intermittent static, fades, then go out completely at times and come back on, popping noises through the speakers & sound seems to jump from one speaker to the other at times.

Volume control has no effect on the issue. Not heat related, same issue cold or warm.

Particular issues with this model or areas to focus my attention on are appreciated.

sounds like a bad audio amp or the power to the audio amp is bad. I suppose the tuner could be drifting. (if you're using the tuner)

The only good way I have found to troubleshoot audio is to O-scope the IN vs OUT.
