Hope you can help.

I have 861v8, UHD722, 5200’s front and centre.

I turned on my system but the centre and left speakers stay on standby, so sound only coming out of front right. I have tried switching everything off, then unplugging and reinserting SpeakerLink cables. Alas makes no difference.

Any ideas what’s going on? It was working perfectly until yesterday and nothing happened to upset the system.

Thanks for your advice.
Bernie
