My Bose wave has stopped working, it has power and the clock is on but isn’t picking up signal from remote, I’ve checked the remote and it is emitting a signal so I’m assuming it’s the infrared receiver module that needs replacing(common problem apparently). The trouble is I’m having real trouble sourcing one as it has 4 pins and I can only find 3 pin ones. It’s a few years old but it seems a shame to throw it away if it can be sorted for a few quid. Any advice welcome, thanks.
