Panasonic Shelf Audio System - No Audio - Model SA-AK630

Hello,

I have a Panasonic SA-AK630 Shelf stereo system and the unit puts out barley audible audio. There is only incredibly feint or no audio coming from speakers or headphone jack.

There is a fan that apparently is dead. Not spinning.

I checked media source, Re-started, Checked speaker wire connections, checked for loose main and daughter boards and fried components ( basicalla visual inspection)

But found nothing unusual

Any Ideas on what the issue might be?

thanks!!

if your circuitry does not have "decent" thermal prot. there might be a lot of issues
. . . but there has been and occasion where the digitally controlled volume locks to default level and can be only decreased -- once you do -- the cold reset ("wall" OFF/ON re-defaults)
you should address local yellow pages on this

Greetings RF ! This should prove to be quite helpful in locating the problem. I tried uploading the Service Manual for your unit but received a security error. Here is the link to where you may download it for FREE ! https://elektrotanya.com/panasonic_sa-ak630ee.pdf/download.html If you have the luxury of access to or own an oscilloscope I would recommend looking at audio signal input/output of Power Amp IC5002. Good luck !
