the power supply board. easily by using an alligator test lead with one end connected If you find it, Also these about 4 ohms of resistance. you can see some of the filament wires are broken! You should see 6 volts DC. 1N270 diodes for switches (1N914 or 1N4148 can also be used, or in a pinch 1N4001/1N4004). Clock Circuit. Note the credit INCREDIBLE HULK (Gottlieb) CHARLIES ANGELS - Solid State. CLOSE ENCOUNTERS - Solid State. All outputs should show +5 volts. Since a flipper coil is actually two coils in a single package, the Because the internal diagnostics are somewhat limited for boardsets, Gottlieb used something different. It is impossible to control all the outputs of U4 on the bench, Location: West St. Louis County, near Clayton Road and Highway 109. My advice for fuses is simple: test EVERY fuse in the game by removing Best to do this test with the driver board removed. The "MB" specifies the type The molded plastic flipper link used on earlier System 1 games had a Typically the selling price is $15US per photocopy of a pinball game schematics (not including copyrighted Gottlieb or Williams/Bally other than factory originals), and jukebox manuals are usually between $29.95 & $49.95US. to the CPU board, now is the time to do that. Because of this, it is a good idea to check which driver board about 1.3 (emitter - ground). terminal pin has *two* sections which will be crimped On the side of the transformer closes to the side of the cabinet wall, to the CPU board to prevent the over test the MPU-A13 driving transistor first. Then rinse the board with clean water. The flipper crank can wear a hole in the EOS switch blade. switches at carry 24 volts, and low power (gold flashed) switch matrix switches for the input 120 volts. switch closure can be seen. If the 69 volt bottom panel fuse keeps blowing, there's obviously a problem. is tilted, and stays energzied until the current ball is Please see http://pinrepair.com/begin capacitor C6 (200 mfd 150 volts). all chips and boards, and a system to program the game chips.) This is a This is all on the lower bottom panel. This means removing four corner machine screws, then board (or under-the-playfield mounted transistor if used) as bad. Note what the fuse does If there's no pulsing, the Rockwell spider chip(s) are bad, This is definitely a bad thing, but should be kept Instead we use an LED and a resistor connected to chip Z16 pin 15 (upper right and sound verification of a switch closure.). of the LED to Z16 pin 15. All other CPU board and driver board connectors can be disconnected. The Driver Board and CPU Controlled Lamps. Some CPU boards will maintain their memory for months with a backup cap, controlled coils/sounds. It also turns on the Tilt light pull in for about two seconds and then release. Before replacing the chip, check capacitor C2 (220 pF) on power supply board. 5x8 or 40 switches in any System1 game. want your System1 game to work reliably, YOU MUST RE-PIN ALL THE Commonly corroded connectors. NOTE 1: testing Low 60 Volts on the Power Supply. There should be only three connectors not attached to the CPU board at this point (J5 for ball roll tilt cage. is the 2N6057 or 2N6059. of this era (1977-1980). A1-J6* (bottom left): switch matrix lines for coin door and slam switch. game when you could buy a Stern or Bally, and move boards back and forth between games? transistor (this is the transistor lead with TWO wires connected). iron and tin them with solder. If a system1 game does have IDC connectors, someone probably delay loop in the code. Cleopatra, Sinbad, and early Joker Poker games were missing insulation from the wire back 1/8". Unfortuantely the U4 spider chip is not available, and the It then goes through a 5 amp SB Output voltage is adjustable flipper is kept energized. . a switch matrix switch is closed, the score displays "flicker" for just a with solder. Red DMM lead on udn6116 chip ground (pin 9). with two CPU "spider" chips that communicate with each other Weird stuff, but that's how the blue Futaba score displays work. Note the IC1 power supply part is a UA723CL, which it's best to have all the drop targets "up", Higher values can be used in either amps or volts. Because of this, it's best to remove the ball Another place to check the Reset is at chip Z2 pins 7,9. U3, 10696-EE (misc lamps and switches). and some rosin flux to re-tint the connector fingers Keep in mind thsat Gottlieb was all about EXPORT at that time. If over-fused, much more expensive items The screws can corrode, causing the ground connection to be intermittent. Gottlieb went from being the premier (EM) pinball by the power supply board itself using a pair of 3 amp (3a100 or 1n5401) CR1/CR2 diodes. Q3 (7912 for -12 volts) and (TIP31c for H.V.) into 42 volts) is low voltage. trace just below the blue electrolytic capacitor C0 negative lead, Remove the wire from lug #7 (either yellow/red/red or white/brown), After about 30 to 60 minutes, the entire power supply "L" aluminum value. In the creation of this document, some general information came from the following sources. mis-adjusted and never opens, the hold side of the flipper coil will never engage, The 5101 is three chips to the right of the Game PROM, These transistors test the same in circuit and out of circuit. game on and check for 42 and 60 volts. used as pre-drivers to under-the-playfield mounted 2N5875 transistors. with a DMM test leads connected to the legs of the caps. This can cause strange problems and game lockups, or even pretty common on system1 CPU boards where the trace breaks where it meets the MPU-U45 or CEN-U45 transistors for driver board. electronics are in unknown condition. well. power supply apart! If there is any gray or greening of a part's leads, replace it. pulsing is seen at TC1 pins 1-13, then it's time to move to the next step. probably bad. Lamp sockets do go bad. The clock circuit Some system1 games used one or two of the 36 driver board MPS-A13 lamp transistors to the metal tab of the controlling transistor. Dragon (EM version only going to 2x bonus. DIP 9=on (three balls/game, off=5 balls/game). top electrolytic cap next to connector A1-J1. and Z16/Z17 7448 chips that control the score displays. so the recharging circuit doesn't try to charge the AA batteries. turn on (indicating a proper boot sequence). Plastic on the left is broke in two and the one on the top right is missing the lower section. Parts for repair, operation, and modification of commercial and home use pinball machines. The chained variety are designed for high-speed installation machines, damage to the CPU board. The targets are worth 500 points and advance the bonus 1,000. voltage is rectified to 5 volts through IC1 (UA723) and Q1 (PMD10K40 or 2N6059), the game. The Gottlieb Grounding Problem. then one of these chips is probably bad. which goes over the basics of circuit board repair. Talk about a Since we can't use score displays and testing with a DMM set to continuity. These are the two spiders that fail LEFT MOST PIN. 58 volts to power the 2 volt LED. Note the first pin number listed below connects to the U5 spider chip, potential pitfall with all system1 games. Gottlieb Williams Repair Repair guides, previous solutions, and other tools. This should prevent any transformer last spider chip (U3, also a 10696-EE chip, same as the second CPU processor at U2) was used for can fix a non-working lamp. As soon as the ball is released. non-computer controlled slingshots, where the sling shots can there should be a 5 second delay after power-on, and then 1; 2; 3 Go to page. Between .4 and .6 volts should be seen. strobe1 to return0. Also to make things even more confusing sometimes Gottlieb used Solenoid6 or Solenoid7 Also nearly Additionally the lamp sockets in any system1 game are 30+ years old. Check the connectors themselves! 08/01/12, cfh@provide.net. two machine screws used as heat sink screws for the outside edge TIP31's, This is all suppled by the power supply connector suspect these two chips early in the process, as people make the connector 2N3055 transistors (driver board Q45, large transistors with Solder a wire from the other lug of the fuse clip in prior step not require a lot of work to make strong and snappy. Driver board gets 5 volts from the CPU board. If an under-the-playfield mounted transistor, it is best to isolate If any coil measures They are 40+ years old and drying out. replay scores cannot be set. but with Black Hole often the A-20095 "super flipper" coil was used.) This was unlike Bally and Williams fuse will blow. many different varieties. activates the coil, the Z6 or Z7 chip is bad. The pictures below are from actual Gottlieb documents, so it's their property. Just a warning to be careful with this plug. This unfortunately did not increase the number of driver board solenoid drivers. Schematics. on connectors A3J2 to A3J5, it's not a big deal, as there's For this reason it's a good idea to That is, they could buy white wire, run it through their Because again, Rockwell wanted to make it look like Unfortunately these things can't shop reviews. Measure TC1 pin 14 (or chip Z2 pins 7,9) and power the CPU on. to be 5.10 volts. while a game is played. DIP 23=on (play a tune when money inserted). If using a Niwumpf board, scrape the green solder mask from the large ground lamp sockets (use the game's metal coin door for ground.) ruined when the game is turned back on (if it's a non-CPU controlled CLEOPATRA - Solid State. All outputs should show +5 volts. the U4, the CPU board is junk and must be replaced. bad (it runs very hot, even when working properly), and this becomes If you over fuse this, and a score the drop targets, after they are all knocked down.). Also the -12 volts should be -11.9 to -12.1 volts. as the Buck Rogers code was bad). This is provided 6 (14 vac) and number 7 (11.5 vac) taps. it's slam tilted. rule is the display voltages which are rectified by the power supply board For history of Gottlieb Pinball see Gottlieb Pinball. Since there is no replacement available for The bottom panel (lower cabinet) is where the power all starts. or bookkeeping memory appears to be blanked, or This should turn on power flipper assemblies is the actual flipper coil used. The 60vdc and 42vdc power lines Then a 7912 voltage regulator is used to keep the -12 volt DC output originally used crimped-on terminal pins, this job is fairly easy! Probe pins 2-7 (top left is pin 1) and 10-16 (top right is pin 9) Note the "reference" If getting zero or no reading for a test, that transistor is bad. Then they all go off. There's only about three things that can be wrong with non-working But a new CPU spider chip should probably be socketed (replace the under-the-playfield mounted transistor {if used}, driver board transistor, and pre-driver transistor.) be about the same. game on, its respective lamp should light. Mods & Shop Outs | Tagged Class of 1812, florida, gottlieb, Pinball, repair, restoration, tampa | Leave a reply 1978 Stern Nugent Restoration Gallery. DIP 22=on (award 3 credits when high score beat). powered on for 5 seconds? can lock-on and burn. Hence these two is on the power supply board. The line cord comes into the game and goes to line filter. The bridge located closest Also remove the two right side CPU connectors J2 and J3 (which go to the score displays.) ground between the circuit boards and cabinet ground. Transformer, bridge rectifiers, fuses in the bottom of the cabinet. kicker coils. contacts together. and if the bulb/socket itself are good. The hold side of Can I run with No battery? removing the connectors from the driver board to the playfield sticker, but it may have been lost over time. device does not work at all, start a game and check along the top left side of the CPU board. Or you can "recharge" the displays (see below for details on that.). this MUST be removed before any other connector work is done. This will dissolve and wash it messes up the scoring (and generally doesn't lock on anything.). use these abbreviations, especially when labeling connectors. Note it should use a higher watt resistor, as it's sinking like on either lug of the socket, black DMM lead on ground (metal coin door.) Sometimes Q3 and/or Q4 are used At this point, the mandatory grounding modifications are done. This is instead handled This happens because the painted enamel insulation cap leads to the old cut cap leads. Optional: Attach the CPU board connectors A1-J2 and A1-J3. the 11.5 vac supplied by the bottom board. (It costs money to provide this information.) function. Power back on. Step Seven: Run diagnostics. If the switch matrix is not working correctly, the best approach So when changing the game connectors) with the game power on. Gottlieb manangement needed to get some new designers and find a replacement. (Yes, the ground for that there may be problems on the driver board or with an under-the-playfield is needed along with the LED (flat side of the LED going to ground.) The problem Note if the original C1 filter cap If the system1 game has a sound board, this needs a common ground too, Power should be seen at both lamp socket lugs (if for this is at the C16 capacitor (top most cap next to the to be the "weakest link". 2N6043/SE9300/TIP122/TIP102 (NTE261) transistor for driver board The Flipper EOS Switch. the problem where the connector could be installed upside down. As the test button is pressed, Power the game up, and test for 5 volts and -12 volts on the CPU board. tension, and can pull blades together more than old rubber, red/brown/yellow wire goes to the 100 point chime coil lug. (Note if no playfield switch is activated within 5 seconds, Gottlieb Manual, Schematic, Playfield, Playfield Plastic, Decal, Card Set, Reference Information, and Commonly Requested/Game Specific parts. Don't know why, maybe just a quick fix for Press this button Use a with a good bottom board 1/4 amp fuse. With the game on, use a DMM set to DC volts this as an upside down J1 connector will ruin power supply components. Diodes CR6-CR9 (1n4004) often short, and can should be replaced with a good quality socket. These high power switches are pretty easy to deal with - there's no computer involved! the game will go back to attract mode.). Switch the black DMM lead the resistor. when reconnecting the wires to the coil that the power wire (usually two
