Should these lights come on when activated or are they overload lights like on the Mackie mixer. No light comes on when selecting the solo button. Any help would be appreciated

You have likely lost one, probably the +15 volt power supply... This is possibly a shorted component or a short on the circuit board causing this. It takes some skills at troubleshooting to find this. Sometimes using a thermal imaging camera will show hot spot... other times you have to search with a millivoltmeter. The rude solo light is driven by an op amp that uses both polarities of 15 volts and to turn it on it pulls negative... Hence I suspect the +15 is missing.

FIlter capacitors in the positive supply are likely failing. These will be the larger metal cans- one may be bulging. Either way, one of them is shorting out after a certain voltage potential is achieved and causing your problem.
Replace the caps in both the positive and negative power supply sections and this should alleviate the issue. Match the working voltage rating, or even one step up in working voltage. yours are likely rated 25 volts, so a step to 35 volts would not pose an issue.
