So I was asked by a friend to look at a machine, it is a 1990 PE, and seems frozen... it has been a long time since I worked on these....
so it has no reaction to turning the key, pressing buttons...
I tried to short the battery to see if that would clear anything. fail...
tested the battery and it is 3.6v
It powers up and seems to show signs of a boot with the screen stuck on " CALL ATTENDANT " I close the door and naada...
coin in time out is also displayed and I tried the door... nothing...
the wires seem fine, nothing seems abused...
it has a " closure restart warning on the lower left.
closing the door seems to do nothing.
Bad Mobo?... it has just sat for years in the corner of a living room
I have press and held the small white Self Test button for at least five seconds and heard nothing...
I have Close and fully latch the door. and nothing... still says it is open
I have Turn the jackpot reset key once. nothing...
but it boots... when it first boots the CALL ATTENDANT is not there then appears meaning the board is doing something
Do I need to get a CLR chip?
