Refer to game manual for component location. C27 (12,000 microfarad 16 volt) should be replaced regardless.īlack Knight speech board electrolytic capacitor list It is recommended that all electrolytic capacitors on the sound boardset be replaced. Factory settings with speech is switch one (on bottom) set to Off, and switch two set to On.īlack Knight sound board electrolytic capacitor listĬ12/C30/C36 1 ų 63 Volt C26 1000ų 25 VoltĬ15 500ų 15 Volt** C29 10ų 25 Volt-Low Leak It consists of switch one and switch two. Located at top left corner of sound board by the diagnostic switch is DIP switch bank one (DS1). The speech board should be fully populated with four ROMs. The sound ROM for BK should be a White Label Sound ROM 5. It is located directly underneath R30, and ties one leg of that resistor to ground) W14 Installed (This is a foil trace jumper that is always present. Can someone confirm on their BK sound board? Confirmed W12 NOT INSTALLED*** W12 Not Installed ***Edited 12/26/15 this is 'PB7 Status Control, with W13 never used.

W1 Not Installed (with Speech Board if no speech board present, install W1) Black Knight should have the following configuration (please refer to game manual for other models): The jumpers could be a piece of wire or a Zero-Ohm resistor, which is normally gray or tan with a single black stripe around the center. This is accomplished with hardwired jumpers installed at locations around the board. Sound boards must be configured for the model machine they are being used in. Inspect the two lugs on the speaker itself and resolder as needed. Gently tug on each of the three wires and resolder as needed. Now inspect the remote volume potentiometer (pot) lugs. Lift the playfield and rest it against the backbox (you may want to secure the field so it can’t fall). Use caution not to mangle trough switches. Reach in the door, on the right (a few inches inside of the lockdown release lever), and work the ball release solenoid by hand to eject the three balls into the trough. Open the door, release and remove the lockdown bar and slide the playfield glass out. OK, so our cursory look in the backbox didn’t turn anything up.

If your meter is handy, check the two fuses on the sound board. Check all socketed chips for bent legs and straighten or replace as needed. All chips on the sound boardset are oriented with pin 1 (divot in corner of chip) pointing downward. There should be no open chip sockets on the sound board or speech board for BK (other games may have open sockets on speech board). J1 at top right is the AC input for the sound board operational voltages (Gray wires).

Next is J4, the remote volume connector (the shield should be on left).

Top left is J3, the select lines from the driver board (J9). A larger, square sound board (with four connectors along the top and a plug on the left) and a smaller, rectangular speech board connected to the sound board via 40 pin ribbon cable to the above-mentioned plug.Ĭheck the orientation of the connectors on the sound board. The Sound/Speech boardset will be located at top right inside the backbox. Also locate the adjustment knob on the Speech board and set it to the center position. (It is assumed that the game functions properly other than no sound).īefore you even pick up a screwdriver, adjust the remote volume inside the lower cabinet on left side to center position. My Black Knight will not make any sound during game play or sound diagnostic. This document may be practically useless. If your board works somewhat, the fix may be mixed in with the procedures and you will have to pinpoint the failure with deductive reasoning. It is further assumed that there is NO sound AT ALL to begin with. If you are reading this document, it is assumed that your BK sound board is not working. However, some signals may or may not be used for your model. These procedures may also be used for other WMS games like Firepower. The following information was written specifically for a Williams Black Knight (’80) pinball machine. Fingers crossed! Oh, and if you find any corrections let me know and I'll edit them in. I have posted this before within other threads, but in a blatant attempt to get in the compendium again it is posted here in it's own thread.
