HELP please!!! I have a Yamaha AX-1 with a funny fault. The left front channel doesn't work with ANY digital inputs. It's OK with analog phono inputs. I had a problem like this 8 months ago. I rang Yamaha & explained the fault. The bloke I spoke to was baffled. He told me to ring my local Yamaha agent to let them have a look at it. Naturally, they found no fault as when they plugged a fibre optic cable into it from a DAB unit & it worked. So I thought nothing of it & brought it back home, as it worked, until now. Has anyone had this kind of fault with an AX-1? Any suggestions will be helpful. Cheers, Neil.
