its the sort of thing you need to have some practice before you try to repair a valuable board
I found scrap PC boards are good to practice on
the last board I worked on was this XMT-2360 speed control board
the 14 pin IC , a transistor and a few diodes had been damaged by a short circuit to the speed control potentiometer
I guess the main issue is finding the new AA6 transistors

PS
have you checked the relay is OK
does it work when its connected directly to the 24V DC supply ?Last edited by john swift; 13-08-2019 at 10:14 PM. Reason: add PS
