Sound like a power problem to me, hopefully a fuse.

If it went up then that a good sign.

My engines not been run for getting on for two years, that about to change.

There are a pair of relays that operate the trim pump from the trim buttons.

I'd suggest you get your multimeter out and start with checking there is power to and from them etc.

You could always swap the relays over, if you move the issue to not going up but will trim down you've proved one of the relays is faulty - quick fix.............

If the motors running for up then that indicates something relatively simple as the same motor just reverses for down.
I'd start by checking the switch is feeding 12v to the down signal relay when its pressed if it is then I'd start checking the connections to the relay blocks take the connections off and clean them and the earths & refit. Likely culprits are- switch, electrical connections, relay or broken wire
In roughly that order of likelyhood
Relays are usualy on the powerhead inside the cowl
Get someone to click the up switch and listen for where the click comes from
