The A1 has an internal self diagnostic program which you can go through to find the fault. You can access the diagnostic program by simultaneously pushing some buttons on the front panel. The Yamaha service manual for the A1 tells how to do it and what the diagnostic codes mean. You can get a copy of the service manual on the web from several suppliers for a small fee.

Volume control


If you are trying to adjust the volume of TV audio input using the TV VOLUME control it can't be done as Yamaha explains in the instructions for your receiver. A workaround is to use the master volume control but then selection of any other source such as a CD player will blast you out of your socks.

Can you help me connect my Yamaha hi-fi system? I want to connect my Yamaha ampliier DSP A1 to my Yamaha equalizer 630 but I don't how to.


Your EQ will be connected to the amp via one of the Tape loops. Connect rec out from the EQ to play in on the A1 Tape input,and rec out from the A1 to play in on the EQ. Then select Tape Monitor on the A1 to hear sound with the EQ settings applied. It won't affect the surround channels,only the main ones. You can also connect the EQ across the pre out and main in sockets for the front channel on the A1

Av amplifier


The display problem is because the solderings on the back of the display are broken. To fix it you have to open the amp and redo the solderings (there are about 50 or 60 of them). There is a Youtube video that shows how to do it. I have fixed this on my DSP-A1.
I also have the problem with the motorized volume control. I have tried cleaning it, and it works for a few days, then it's stuck again. I guess I will have to replace it to have it fixed permanently. The part number is VZ621400, a new one costs about 40$.
