MTR-2000 repeaters are notorious for issues that require a power reset, less
often with the latest version of firmware, but still require reset, there is a
service bulletin on this.

This is a regular issue with many controllers, especially Trident
Raiders several Comm Spec units, and Motorola MTR-2000 repeaters.
I have yet to find any type of relatively complex software driven
uP in controller operation that didn't freeze or fart (lock) up at
some point in time. One would hope the mfgr hopefully included some
type of dead-man or equivalent software-hardware reset timer.
Years ago Comm Spec supplied a small board that reset power
to the controller to eliminate the problem.
For the TP-3200 Tone/DCS Panel... and they were smart/nice enough
to provide the timer daughter-board as a free retrofit.
We installed power reset modules on all our repeaters, every
24 hours,
The Comm Spec supplied timer cycled more frequent.
power is reset to the entire repeater, usually about 3:00 am.
Is/was there any reason to cycle power to other portions of the
repeater hardware?

We have 2 repeaters that are more or less the same. One is
on 2 meters and the other is on 440. They both exhibit the
same problem, they lockup after a while and then need to be
power cycled.
Q: The repeater hardware (radios)? the Zetron Controller? both?
Did/do you test to find out what is locked up (not working)?
They ran for years without issue.
We have the Instruction manual for the Zentron controller, but
nothing on the radios.

You shouldn't need much in the way of manuals to do the basic go,
no-go testing. A received signal should indicate on both the RX
Radio and the Zetron front panels. The Zetron should indicate
valid tone/dcs codes and the Tx activity should be indicated on
both the Zetron and TX Radio front panels.
Step two depends on the answer(s) to the above question.
