Hi everyone-
Before I dump this Panasonic SA-XR25 I thought I hit you up for suggestions.
It’s at least 10 years old and has served me well. I decided to hook it up after having it sit for a few years. 3 fronts and subwoofer crackle like crazy. If I play around (on/off, switch audio mode), it sometimes will stop and perform fine. But I’m going through all that.
Here are some pictures of the inside. I did notice something which what I’m pointing at. Also noticed the fan no longer runs.
Dump it?

It looks like the power amplifier board is grounded via its mounting screws. I would loosen and retighten those just in case. Same might be true for the input board (?) on top of it.
BTW, I spot an AK4114 SPDIF receiver complete with two crystals for both 44.1 and 48 kHz multiples - they were not skimping on this one!

If you don’t mind, take a look at the second picture. Towards the right there is a grey plate with ‘A1135’ (or something close to that). Right above it, in between the two round thingies (no idea what they are 😕) you’ll see some brown stuff that almost looks like it leaked from somewhere. Is that a concern or part of the build?
Thanks again!

You may find this interesting ... Bad Glue
Apparently there was a run of mounting paste, used in the soldering process, that starts out tan or yellowish colour but ages down to a hard brown glue that actually turns conductive and can cause all kinds of havoc in a circuit.
Whenever I've seen it, I always take a tiny screwdriver and gently scrape it off the boards.
Aside from that... a really good cleaning of your controls and switches, blow the dust out, maybe check the drive voltage on that fan and then see what you've got and decide from there.
