HELP! Sony STR-DE597 A/V Receiver not outputting any sound!

So I know this receiver is not the newest model, but it has served me well.
I currently have it connected to a Bose surround sound system and connected to my PS3 via toslink.

Unfortunately, the receiver has stopped outputting sound. I have tried changing different inputs (e.g video 2,video 1) but not luck. I have also tried changing it to the AM/FM tuner, but still doesn't output anything.

Also, when im using my PS3 and it is outputting Dolby 5.1 surround sound, the receiver has a blue glow which indicated the 5.1 surround. So I'm assuming the signal is getting to the receiver, but nothing is being outputted.
