Yamaha A-S801 no output

Two minor points: The 801 transformer does get (slightly) warm ,so the amp is working; I am not using the stock power cord but an Anticables Level 3 power cord.  This should not matter but if it caused some kind of thermal shutdown then the 801 power light would blink but it is a steady glow.

Shot (s) in the dark -

1) any chance the mute button has been engaged either on the remote or the unit itself?

Thanks for the thought but turning up the volume defeats the mute function on the remote.  Tried that early on; no joy.

Do the 801s have jumpers in place between the high and low frequency connectors?

It seems the CD output is not getting to the receiver. Try using the stock (or another pair of) RCA cables. Sometimes these expensive connectors fall short just enough not to make contact. Also give another look at where the RCA’s are plugged into to confirm it’s CD (analog in) and not PCM... and the input selector agrees.

A long shot may be an an intput relay has failed. If the CD player has a digital out try testing it with the PCM input to the receiver.

Thanks.  Swapping out the RCA cables was next on my list!  I appreciate it.

Two Suggestions:

1)  Ensure the INPUT selector on the A-S801 is set to the correct input (e.g., “CD”).

2)  Verify the SPEAKERS selector on the A-S801 is set to “A” or “A+B” (not “Off”).

Thanks to everyone for their suggestions.  I changed the CD input from 'CD' on the back of the amp to Line 1 on the amp.  Switched the input selector on the amp from CD to Line 1 and Voila: music.  Have no idea why this worked but it did.
