Fruit Machine Chat

hi everyone, sorry to jump in like this but needed some help with my fruit machine,
it not lighting quite a few bulbs up and they all seem to lead back to the same wire from a circuit board. i wondered if anyone could identify the board so i could stand a chance to try and find a replacement ?
its from an astra pharos gold machine
thank you in advance

Its an integrated IO3 board

thanks mate, would they be easy to come across ? or are they fixable ?

Are you sure it is the mpu, it could be a broken common wire that links them all,If it is on the mpu,check which transistor / diode / resistor it goes to and check with a multimeter for an open circuit
