Game: Star Wars Episode I - Williams Pinball 2000

This is my first pin so very much a newb. I have had this pin now for a few months and the entire time I have had a fuse that is blown and when I put in a new one it immediately blows again. From what I have read this most likely means there is a short somewhere. The fuse in question is F112 (T5A 250V) which handles Lamp Matrix B.

First question is if it is a short in the lamp matrix, is there an easy way to trace the short to the correct lamp?

Second question is how to decipher between a short on the board and one in the wiring?

Anyone else have this issue (or similar) with a Pinball 2000 game and willing to shed some light on things to check?

Best start to check diode D33-D36 for a short with a multimeter

OK so I have a short in all 4 of those diodes. Thanks for the help! Now if anyone knows a good repair shop near San Jose, CA or a shop to send in my board for repair.

ChrisHibler or Borygard both do excellent board work.
