My Spoilt Solenoid..

Hi bros..
Been a while since i last post..
Committed to NS ah.. But recently i found out a problem. It seems that my UP Brand solenoid is not working.. i dismantle it to check whether the triggering device is working or not, unfortunately it was faulty. Bought it 2 yrs ago.
My question is whether there is any way for me to fix it or get is working again? Now i had to detatch the trigger and turn it like a manual regulator.. sigh..

Any advices on where to get it fix?

Thanks,
Fazdli
