Hi everyone Thanks for having me on the forum 
I have a Bell Fruit DoND with a Scorpion 4 MPU. It was working fine but has just stopped. The bored has 4 green LED's and the red one is flashing with and without the game card fitted. From what i can remember it is a Stadium PSU.
I removed the battery about a year ago as it was leaking and caused a little bit of damage. Im not sure if the battery has to be installed for the machine to work.
The machines casing isn't in the best of conditions and some buttons are missing so if its anything serious i'll strip it down for parts and buy a different one.
Any help would be much appreciated..
Thanks in advance
