Is it possible to use the trigger out from the Fosi Audio ZD3 to two pieces of ZA3 amplifiers?

Yes, use a dual 3.5mm male splitter cable to trigger the ZA3 to switch on synchronously.

How to set up a system using two ZA3 units in mono mode?

- Connect the RCA (XLR) cables to the right-channel RCA (XLR) input ports of the two ZA3 units, and link the speaker wires to the right-channel binding posts.

ZA3 recommendations for replacing op-amps in mono mode?

If you're using RCA mode, please replace only the right op-amp. For XLR mode, swap the right and XLR channel op-amps.

No front light on ZA3 though there is light on the ac adapter.

Long press the volume button for 2 seconds to power it on.

The power on LED light on my ZA3 is dead.

Check if the LED is misaligned with the front panel hole, especially if the op-amp was recently changed. Misalignment could cause the LED not to be visible through the case.
