Fruit Machine Chat

My dad has just got this machine from my niece, who had it lying around in her garage for a year or two. http://i585.photobucket.com/albums/ss29 ... C02973.jpg

It's not working, not booting up and some status LED's light up sometimes and then the next time they don't.

Currently on powering up:

Power supply unit-all LED's are on.

Security LED out
+12v ok
-12v ok
+5v ok
vidisp LED out
Reset LED out

Sometimes all the LED's will work except for vidisp.

Front door board (Lamps) LED is on.

Could someone give me some advice please. I'm a novice but my brother is the electrician (works on airplane wings for BA) so any info to get this machine to work would be appreciated. Is there a battery on the mpu board?

if u unsure about changing parts give us a shout i work in bristol area most days

Update:

Purchased a replacement mpu board on ebay-arrived next day-installed in machine-working fine

Couldn't see the battery had leaked until I took photo of it and turned the board over, to see it had blackened the underside.
