i posted in the tech section but since this is a LOTR post i was curious if anyone has had this issue:

An odd one. Lord of the rings, did work fine. Turned game on, started to play, left flipper died. Fuse next to flipper blew. Replaced fuse, upon power up flipper sticks up and blows instantly. All wires to coil and eos as fine, not broke off..same with flipper cab switch. Pulled driver board, left flipper driver transistor was blown (Q15). Replaced driver transistor and fuse. Power game up, flipper sticks up, blows fuse instantly. Pulled driver board, it blew the new transistor. So now, replace transistor again and replace fuse and added a new flipper coil for giggles. Power game on, instantly blows fuse and fries new transistor again. What else?

PS: i tried the driver pcb in another game and it works fine after i replace the transistor for the left flipper.
it only blows the transistor and fuse when its installed in LOTR. I've owned this LOTR for 15 years. Nothing has been messed with.
can the mpu make something odd like this happen?
