I'd look for a short in the places you have done repair/adjustment (you did, right?)
problem is that a short often blows the U20 and/or U14 chip on your cpu board.
a real pain in the butt.
here's a link to my troubles
good luck

ahh well. i'm no expert on pinballs but pinmike and B_R walked me thru my troubles when my pin was down.
It took me a month to fix it and i had to learn how to use a multimeter and how to read that manual.
i really think that you have to go thru all the switches under the playfield and search for that short.
at the same time get someone to solder sockets on your cpu board for those u20 u14 chips, they could be burned
