Hello all, this is my first post, so please be gentle smile

Firstly, this is what i have, Yamaha RX-A2010 amp, 2x QS8's, 1x VP150 and 2x Dalis as the mains, EP 500 V2 and a small cheap sub.

I had made a few small adjustments to the controls and inadvertently switched one of them to Load. I read in the manual that this would cause the sub to switch to the Amber color and not the green, hence not work.
Even after switching it out of Load it still remained in Amber, I did manage to get it to turn green again by connecting the second sub (el cheapo) to the output jack on the back of the EP500.

I thought all was ok, but shortly after that it switched to red.

This is what I have tried so far...
Changed power points, changed cable from Sub to receiver, connected cables to the High level and then to the front left and right outputs on the receiver. I have also checked all fuses and tried connecting the old sub to the output jack as I did before.

The light has however changed to amber and not red like it was, but I still can't get it to work.

I am guessing it is a problem with the subs amp and I need a new one?

Is there anything else I can try or is it dead?
