Pioneer AV Amp suddenly 'lost channels'

[Sway]

Have a fairly basic setup. Pioneer SC-LX58 amp, 5.1 Monitor Audio teeny tiny speakers.

All working fine for the last couple of years, using the auto setup with microphone thingy.

Watching TV the other night, there was a 'pop', and the amp restarted. Since then, no centre or surround channels are working (just front l/r).

Have tried redoing the setup. No joy, no test tones played from the three speakers. Have done factory reset - no change.

Any ideas? Or recommendations for repair in West Sussex (Chichester)?

Thanks!

Sounds like a capacitor has gone pop, will need a repair if you can find someone to do it. Probably easier to just buy a replacement of eBay if you don’t need latest functionality etc, I’ve got two older AV amps in the loft that only got replaced because they didn’t support 4K TV’s and were not worth enough to sell
