Hi all,

I have a cops n robbers gold, suddenly it went off whilst being played and came up with the following fault sequence after re- initialising.

WRONG SND ERR 97
UUUUUUUUUUUUUU
SOUND MEM ERR 98
then “CHECKING ROM’’
then finally PSU ERR 56

I have checked the main board and all 4 green lights are showing, checked all the plugs around the board perimeter, finally removed the Power supply unit, removed cover cannot see any evidence of burn out.
Checked all outgoing voltages at the pins and all correct.

Any ideas anyone!

Hi all, just joined the forum and looking for some advice please.
I have got a cops and robbers gold club machine, which ever since I bought it has often played up on starting.
When switched on it says initialising then steps thru the sequence, then at the absolute final point before machine all lights up and good to go, it goes dead and starts over again.
The original owner said the fault was at the battery ( which was just starting to leak, none yet on the board), and whether a coincidence but when cleaned at the negative pin started first time.
Since buying it, I have now connected a new battery with fly leads but if anything the problem has got a bit worse, needs 3plus goes to start before it only took about 2 goes, so could be getting worse.
The key point though is when the machine is warmed up and turned off, it reboots first time no problem.
I am happy to ignore this as long as the fault does not get terminal and not start the machine at all.
Thanks to everyone in advance for any help/advice.
Regards,
Martyn
