My original tuner module failed recently. I was hoping for a loose wire in the harness, but after swapping players, sleds and it with a PCAT tuner, I've come to the realization that it is the tuner module.
It typically works for a minute or two before dropping to a extremely low (unlistenable) volume. Antenna signal strength remains fine even after the sound cuts out. Are these the symptoms of a bad RF module, or could it be the op-amp, or something else? In either case are parts still available for a repair?
