I just got a williams sorcerer pinball and when i turn it on it flashes lights on the backboard and flashes oo oo continously...it also makes a clattering sound where you install the quarters...i then have to push on the reset switch on the main board over and over until it finally goes to service mode and this time it stops flashing and the clattering noise goes away...it displays 40 00 and when i move it up to 40 50 to try to reset it it goes back to blinking and clattering and displays 00 00 over and over...the reset stays the same when i push it it does not give me any number at all...can someone help me with this problem...thanks jaime
