Amp protection lights on

[PWRmx24]

My old faithful Rotel RMB-1095 (5 ch 200w) amp has two saftey protection lights on that won't go out. I turned it on and off a couple of times and disconnected the speaker wires but the lights are still on. The other 3 channels work fine. Any ideas what to do next, other than take it in for service?

It needs service. Most likely power transistors have failed. I would not use it with protection lights on. Leave it unplugged. The problem is that there are no service guys left. So if you don’t have the test equipment and experience with servicing complex electronics, your options are likely limited.
