Stopped working

Family has owned the Sony STR-11L since new.

Stopped working last week.

Over the last couple of years when powering off the speakers would pop even if the volume was set to zero. Volume would crackle sometimes when turning the deal. Everything else worked fine.

Will turn on, no sound. Meters do not fluctuate so could be a more fundamental issue.

Can anyone please help out with fixing the our Sony STR-11L?



Sony STR-11L

I also have a Sony STR-11L and had a lot of noise and crackle when powering on and when
turning the deal.
There was a lot of dust inside why I cleaned it with compressed air,
especially the air capacitor. The crackle and noise disappeared.

Best regards,

It is dusty but even after clearing away the dust still no sound.

The lights come on.

Looking inside all the components look good. No burst capacitors.

Maybe the volume and balance control needs replacing.
