2 things you can test.

Power supply and Ysus

Test the FETS on Ysus for shorts.

Test the FETS QX001 and QX002 on power supply as well as the power caps

hope this helps

unplug the y-sus from psu, see if it still clicks.

if it does, then its psu fault, check all capacitiors for bulges, and as obagama said, check those 2 fets, im sure you can get a repair kit for around 15 uk pounds.
