Sorry for being unclear fruitman69
The Big board stuck on the back inside is MPU5 Looks like a big Chip board .And you can unclip the centre part.
And Looking at the reels from above,just under the reels it says MPU4.doesnt look easy to get to.
What is a PSU?
Can you tell me in your opinion what i need to get, the best place to get it.
Thank any more info will get it you no problem.
Thanks
steve
