Another Dead Boom - any ideas ....

My trusty Boom has died - in a slightly different way to some of the others on here so grateful for any ideas....

After being off for a few days while we moved house, I plugged it back in and it went straight to the Setup Networking Screen - slightly oddly - it normally sits on the Logitech logo for a couple of seconds, but this went straight to Step 1 of 5 Setup with just a blink of the logo. Then, it just sits there - won't respond to any button presses at all on the main unit - even power off etc.. Do the reset buttons (1, +) work on the main unit, or only on the remote - since moving, I of course can't find the bleeding remote. If it's only the remote, does anyone have the remote codes that I could program into something else to try and send them. Anyone else seen similar behaviour.

I've tried a different power supply with no luck, so it's not a low power situation.

Thanks
