I have a problem with an old Technics SU-G75 Amplifier when I go to turn it on it'll make a click noise, but it doesn't report anything on the display as it wont turn on, and also there is no sound output when hooking speakers up with it. I have also uploaded the manual but haven't checked everything but need some help in trouble shooting the issue?

I have taken it apart to see if any connections were fried and to my eyes none of them seem burnt or anything. It has worked fine in the past, never had any real issues with it, always ran great.

I changed the fuse and it didn't work. everything works fine hooked up to the other components but the amp - no lights - no nothing. however, everything else is operating fine.

Any input helps, thanks in advance.
