My brain nearly melted as I was using my cellphone to look at the schematic Rich sent me.
There are four fuses in the left channels: 401 and 402 on the front and 501 and 502 on the surround. If any of those blow in any combination, then *both* left channel LEDs (D004 and D005) will come on. Don't ask me why Rotel didn't just use a single LED and call it "left channel protection" or protection chips for each channel (which admittedly would have complicated the design).
Those fuses I referred to above are likely buried as Rich mentioned before.
There could be other circumstances that lead to the LEDs being on besides blown fuses. For example, an internal fault in the protection chip.
Chess, when you plugged it back in, did you cycle the power switch?
