Thank you for all the offers of help, and anal rape!
When we first got the machine it turned on, started test mode, span the reels the started flashing 23.
We checked all the wires to try and see if anything was missing, played with the tiny coloured switches and tried again. Now it doesnt spin the reels, flashes 69 intermittently and making a noise like a speaker popping around every 15 seconds.
So far it hasn't made any other noise.
Let me know if you have any questions or if I should just take a baseball bat to it
