Its actually a VR3080. I have had this receiver for 6-7 years. It started behaving strangely some time ago. It started taking a while to 'warm' up. I would switch it on and leave it for 5-10 minutes and then the audio would come through. Now it doesn't even do that. Seems like some component in there died. I have it opened. Any ideas?

Thanks
