Firstly a big high to everyone! I hope this is the correct place to post my cry for help.
Apologies for a long story but it may help in the solution.
I purchased a working SF2 hyper cabinet which had been fantastic for a good few years. One day I cranked it on to find a green screen complete with game sounds.
Electronics are not my strong point so I began my endeavour to try to find someone to fix it. Living in the middle of New Zealand I found my options very slim, until one day a guy that fixes pokie machines said he could fix it!

He installed a new Wei-Ya 1220H Chassis stating it would solve all my problems but alas the same green screen.
He then pulled some wires out and said he would be back to try some other stuff. That was now 6 months ago and he's somewhat disinterested in returning making excuses when I rung.
So I thought bugger it I'll try myself - and researched what goes where.
I think it seems correct, but I no longer have power to the monitor and also it blows the 2amp fuse every time I plug it in (game music does work).
The only connection I was unsure about is the red double wire from the degaussing coil. It does seem to be designed to go where I put it though.
So any ideas I'm happy to try!
