Yes, checked that. Curiously enough it doesn't seem to matter whether it's
in test mode or not, I still have the player one button lit.

Is it a bulb or LED inside the player one/two buttons? If a bulb then maybe
the player two bulb has blown, so that's why that particular one isn't lit?

There's no audible response when I press any buttons.

Not sure where I'd look for one to be honest - I'm in the UK.

Anyone here in the UK with one fancy a trip to Bristol? ;)

I've completely disconnected it now so no power is getting to it.

Incidentally, there is a noticeable low hum coming from the PSU. Is that
normal?

Thanks for your help,
Phil
