Need Help With Korean A-One AM-0629 Chassis
« on: March 18, 2019, 12:20:22 am »
I am fixing this chassis for a friend and am having trouble. I have deduced that the problem is most likely the voltage regulator however I have no idea which part or parts comprise the voltage regulator.

The chassis is the type that was used as a replacement chassis for 1980’s video arcade games. Unfortunately, no documentation seems to exist for this chassis. The closest schematic I have located can be found Here.

A larger image of the chassis can be found Here.



Any help would be greatly appreciated!  :)

I did a cap kit on the chassis. No change.   :(

If anyone else has any suggestions they would be greatly appreciated!  :)
