I have a Panasonic Surround sound system and it's not receiving my remote control signal. It has been boxed up for a long time.I have checked the remote on a phone camera and it's blinking fine. Any idea on how to maybe sync it or get it working again.
The remote would not normally need to be synced or activated on a surround system.
Since it is putting out IR there might be a problem with the surround sound system not the remote. The IR receiver would not usually be affected by dust but if it exposed then cleaning it can't hurt. If it is enclosed behind the front panel it would be hard for dust to get in there.
