After five minutes, the Tonelab
What it sounds like is that the thermal overload protection is engaging because there is a component that is overheating. I don't know what the operating voltage is of 12AX7A/ECC83 but I would imagine that would be one of the hottest components in the chassis along with the switching power supply. There is an issue with your pedal however it is tough to say without looking at it. Sorry I couldn't be more help. Good luck!
It's been a long time
I would expect a problem with the power to the display. I believe these had LED displays and they use a reasonable amount of current. I would expect he power source for the display has a bad source of power. If poowered by an adapter, possibly the wrong adapter is being used with insufficient current capability or if powered from teh amp, then maybe the wire that brings the display power down is broken or a connector for that cable has a problem.

The most likely case is that one of the main output transistors (if which there are many) is shorted. When the protect circuit senses DC on the final output, it will not allow the output relay to come on to protect the speakers from raw DC. With the power removed, you can check between each outputs Emitter and Collector and you will probably find close to zero ohms. From that point you need to unsolder each of the pins of the bad channel until you find the shorted device(s) and replace them.

No or very little sound from Fender passport
Depending on the model, there are four around that date, it could be the insert jacks are tarnished reducing the signal flow between the pre amp stage and digital power amplifier. It could be the power amplifier has failed. It could even be customer error in wiring.
This assumes there is the correct level of signal entering the input sockets of course.
