Bucks Fizz Barcrest machine says door open

[sjhoughton]

Hi

Can anyone help please

Hi can anyone help please.

I bought an old fruit machine, Bucks Fizz and its been working fine for the past 6 months

ive not used it for 3 or 4 weeks and when i turn it on now it just says door open. The back door is on and it will reset and I can press the start 10p button and then release money but It just wont work after that it goes back to door open if when I have put the back door on or if I hold in the White Switch.

Every time I turn it off and on it goes back to DOOR OPEN

When I press the black button twice It does various tests on the lights and the sound but just cant get it to work

Anyone know what the problem could be please.

thanks
Simon
