Parts for M200 MPU board
Sarver Systems:
I've also got no feature lights. All of the general lighting works though.
All of the solenoids fire during the test, but not during play mode. Not even the ball kicker to start the game.
I'll check the fuse, anyways.

that is :gui: is working..
if they work in :in test mode: but when u exit and go to game mode
look at the light on the micro..if it is soild on the mpu is locked up..
do u have the balley test manual handy ?
it will tell u what the blinks mean
also them things are noted for :bad: board connectors..both on the mpu and the driver board...hudge hint here
shut it down..turn it back on and listen for a click..>realy<..on driver board
this controls the flippers
it should click..if not refer to the manual and find the wiring route from the mpu to the driver-board,also on the power-supply there is a over-all fuse,that supplys this voltage,if it is blown ?,then u have a down stream problem >driver,coil<..
u stated u swaped u7/u8...no these chips are not the same ,there #'s may be
but back in the day there 1 time programble :pia's:= one time programble i/o chip
u need also to chk for the jumper on the board that make up the .cfg of the mirco
it did very between machines..ie jumper 1 could hook to jumper 3 on kings of steel
where jumper #1 could hook to jumper 2 on kiss
u must watch for this

I meant to say I swapped U8 for the chip rioght beside it...U13 I think it is?
It didn't make any difference though.
Anyways, I am very leary of the light board as well. It is pretty corroded, and I'll end up replacing parts on it as well I'm sure.
I for a manual off pinwiki that shows every continuity test for the U8 socket, and I fail on 2 of them, so I'll have to dig a little deeper on that too.
I'm at work right now, so I can't post any more details than that until I am at home with the board in front of me.
