Fisher ca 9025 amplifier. Stereo is about 12 to 13 years old and always worked great. then one day

Question

Stereo is about 12 to 13 years old and always worked great. then one day went to turn it on by the remote and nothing happend. i checked all the wires and everything was hooked up properly turned off main power and unplugged to try to reset the amp the only light that was on was the red standby light nothing happend. so i took it apart and found one fuse it looked like it was intact but at the end of the cap it had a slight bubble i didn't no if that could cause the problem of not turning on or what this may be this system kicks and has clear music id hate to throw it out or spend a lot of cash to fix it what do you think the problem could bemine is in standby. If I hold the tuner button for anout 10 sec when I release button a relay clicks and unit powers up for about 8 sec then relay clicks off and back to stand mode and this happens with all components unhooked from amp
