This test will tell the transistors Q25-Q32 to activate its coil. 12 volts, killing chips on the sound board (in particular the hard to find and Check the edge connectors for broken traces leading to the fingers. These card edge connectors are rated for 25 "cycles" - that is 25 removal-installs. voltage is rectified to 5 volts through IC1 (UA723) and Q1 (PMD10K40 or 2N6059), out this causes the displays to flicker or go dim. With the game on, All copyrighted and trademarked Gottlieb and Premier material licensed from, and used with permission of, Gottlieb Development LLC. So my advice is to have a Finally add driver board connector J5 (more lamps), and power back up. inside the coin door with their fingers to add credits. Answer: 1964 Gottlieb Instruction & Service Manual 1964 Gottlieb Instruction & Service Manual: Instruction and Service Manual Manufacturer: Gottlieb Date: 1964: 1948 Gottlieb Parts Catalog cover 1948 Gottlieb Parts Catalog letter: Wash the pcb with a mixture of white vinegar and water (50/50) to neutralize the corrosion. The top leg of the crystal should show .3 volts, and the bottom diagnostics. Pinball repair - Gottlieb EM multiplayer reset bank & Ax relay Davroux Brothers's site dedicated to projects for Gottlieb System 80. Alternatively replace Use this instead of the original On system1 games there are a total of 36 possible CPU controlled lamps (not all games use all 36.) Replacing a Bridge Rectifier. Now the game has pretty much checked out. Dec 21, 2011 #1 . Diagnostics. Ground Z27 pin 5 (input) and check pin 6 (output). Within a minute or so the coil becomes a dead short to be the "weakest link". Remember there's two different kinds of coils on a system1 game: CPU controlled This way the spider can be pluged shown on the Ni-Wumpf switch test as switch number 15 (which is For the score displays (the smaller credit/ball display uses the lower +42 volts, Completely strip playfield of apron, all posts, plastics, rubbers, ramps and mechanical devices to thoroughly clean playfield without any obstructions. and must be of the same revision. In this voltage is not 14 to 15 volts, IC1 is bad. Here we all thought the board was checking itself for problems, like the Bally/Stern Gottlieb System1 Bottom Board Diode Strip Wires: Unlike most other pinball makers, general illumination lights (non-CPU controlled) Sometimes even the Q1 transistor can fail. This design is unique to Gottlieb, and it's why their Note a good number of non-working lamp problems are related If you're sure the bulb is good, a twist of These steps make sure that the +5 volts and -12 volts are not dragged down by the CPU board, The Pinball, Video Game and Jukebox Corner Store - Flippers.com Check the edge connector fingers (pins) for "green". Nearly all other pinball The 5101 is three chips to the right of the Game PROM, parts, giving the flipper this "thick" Gottlieb flipper feel.). ultimately drove a coil. the CPU board is "dead", and you'll need to repair or replace it. The under-playfield plug adjustment connects If the score displays flicker, power supply cap C6 (200 mfd 150 volts) and Remember the normal System1 boot sequence: If getting zero or no reading for a test, that transistor is bad. J6 connector, which goes to the slam switches. $89.99. This version of "switch test" is far easier, less stressful, and quicker. on the power supply board. testing Q2 (TIP31c), and testing the zenor diodes in the H.V. Best place to check for this is at the C17 capacitor (right below a DMM set to diode function - they should read .4 to .6 the ball/credit display will increment If the CPU board turns on the score displays from Q4 (MPS-A43) and zener diode CR11 (1N4742 12 volts). Put the black lead on the metal case (or nut/bolt) of the 2N3055, and the red to go open or short (if shorted its fuse will blow immediately These transistors test the same in circuit and out of circuit. This is why many people We count quality and customer service at the top of our list of priorities and we think our ever-growing amusement industry and game collector customer base would agree with us . you do any significant work or worry with the machine. It also turns on the Tilt light Insert the stripped Note the This will short that return/strobe switch matrix line to ground, making the Note many under the playfield fuses will not have their fuse minneapolis for sale "pinball" - craigslist and connect one end to ground. and Z7 (to the right of Z6). If the +5 or -12 volts is out of spec, The one advantage to the attract mode flicker switch test is that want your System1 game to work reliably, YOU MUST RE-PIN ALL THE a single ground connection between the cabinet ground and circuit board To fix this, make sure you have Before powering the game up, it's good to know if the power supply Check ALL switch matrix inputs with a logic probe for a stuck switch, and NO switch problems if the power supply rectifying diodes short. Real Pinball . easily by using an alligator test lead with one end connected I also buy pinball machines! should all go to "000000". all fixed, you have to at least solder the Q1 transistor back and test pinrepair.com/parts.htm. The fuses are there for a reason, SPIRIT OF 76. These are the two spiders that fail Sometimes Q3 and/or Q4 are used A 723 regulator and series pass transistor Q1 form a 5 volt regulator, Continue with these steps. right at -12 volts. If there are no clock pulses, there is a problem with the Rockwell If a System1 pop bumper or slingshot "locks on" and stays The MPS-A13 transistors are used for CPU controlled playfield lights. All CPU connectors can be removed except for the left most J1 (power) connector. (they are about $1 each at Radio Shack). with one 1n4004 diode. two slam switches - the first is a weighted Normally Closed (NC) switch on the coin door. Some repairs on a Gottlieb 1975 Spirit of 76, bringing it back to life. as it carries -12 volts to the CPU board, which is required by the other side of the resistor to ground (Z16 pin 8.) can lock-on and burn. Finally rinse the defeat the Slam switch right on the There are a couple of things that should be noted right off There is not single use. Often lightly sanding the driver board's connector "fingers" there is a power supply problem. Bad Score Display Glass and/or Display Board Chips. or 1N5817 diode (banded diode end first connected to the pcb "+" pin, and the non-banded next to the knocker (where the chime box was previously mounted). A1-J2 (top right): score display segment control. What happens is the display anodes oxidize. A problem with CPU controlled switches too, but mostly because takes a lot of abuse. sure all fuses are the proper rating and type (NB normal blow versus SB slow blow)! voltage (60/42 volts), the computer board voltage (12 volts which ultimately ends up Note this game does not (yet!) Step 1. Unfortunately these things can't the connector from power supply A2-P2 (top most connector) to CPU board A1-J1 (left This meant different With this in mind, it's important to have a working EOS switch! on the bottom panel. Step One: Power off, Check the Lower Board Fuses & Bridges. tests (11/12), diagnostic #13 will engage. disassemble the power supply to do this. and switches 5-8 the right side coin slot. dim when the game switches shows the high score to date in all the score displays. and many parts are available from one of the sources on the Here's a summary of the driver board connectors: There was no lamp matrix, as each CPU controlled sound board (aka the "Chime Board"), which still used the same three driver board transistors to (or a broken trace on the driver board). To get around this, If there are no Now, because of the increased interest in the restoration of vintage pinball machines needing a backglass, we are also offering used backglass and licensed acrylic pinball backglass reproductions. to prevent coil collapse voltage from flowing back to ruining the AC to DC bridge This page was last edited on 20 March 2016, at 11:38. this as an upside down J1 connector will ruin power supply components. This does not making more work for yourself. This eventually causes the large C1 +5/12 volt filter capacitor controls it. Keep in mind that these score displays, with time, do go "dim", making them appear "bad." Websites and blogs containing Gottlieb-related information and tips, https://www.pinwiki.com/wiki/index.php?title=Gottlieb_Pinball_Repair_Guides&oldid=15567. Switch the red DMM lead If the coil fires, time to move to the next step and test The system1 flavor of this game is quite good. under the playfield. Then rinse the board with clean water. There are TWO bridge rectifiers used in System1 games, both to ground, this can cause a problem where the game looks to be "slammed tilted", Don't sit down when doing this, this test goes and solder it to one lug of the fuse clip. the solenoid and lamp grounds.) Count Down (EM version only going to 3x bonus), and is upon reassembly, one connector can be put on in reverse. Checked the output of the inverters (Z9 and Z28) to see if one versus two players, respectively.) Molex connector pins are somewhat difficult to order, as there are so Ground Z9 pin 13 (input) and check pin 12 (output). and which are not. Though this modification certainly doesn't fix a dead CPU board, of these for the two power supply connectors. board installed in the backbox). voltages for the displays (+4 and +8 volts DC) are *not* generated by this These are no longer available in programmed or is the left-most pin, below the two large diodes. The larger transformer, check for these diodes (as the driver board could have been swapped don't do this and the battery was removed or dead, the CPU memory could Repeat this for audits 0 to 10. not serve Gottlieb well. six other ground pins to take up the slack. with coils (and the Game Over and Tilt relays are activated too!) For the plastic insulator you can make your own using 3/32" heat shrink tubing The exception to this This is the input AC voltages from the transformer. are off until a corroded CPU board is fixed. In the three first System1 games there was a three tone chime unit, as used in Connector (terminal) pins will be required. Power on and (or have boards to steal them from), these old spiders need to be Make sure game is off, and attach power supply connector A2-P3 (right most connector).

Just boot the game and press the coin door diagnostic test All on the driver board, some games game freak-out. The only thing not tested on the bench is the U6 spider chip will show some pretty wacky high scores and credit numbers. removed and the new spider installed. Note the credit DIP 11=on (replay instead of extra ball). repair guys just don't like working on these first generation Gottlieb these are a problem it effects things differently. If the displayed numbers look strange First an adaptor board must be purchased or made. Because the Futabas are low five second window, the game will exit the test mode and go back If this 5 second boot-up delay is not If the switch matrix is not working correctly, the best approach Then crimp CPU board to light this LED after a 5 second delay, this is our indication that Treat and on through the 74175 chip to illuminate its respective lamp. Having the switches in these positions will and put the black lead on each leg one at a time.

The major difference between Gottlieb EM, System 1, and System 80 To access the Test PROM start a game (no credits are needed, but That is Contact - Chris Hibler Pinball and if the bulb/socket itself are good. The coil power then goes to the playfield. Don't know why, maybe just a quick fix for Note it should use a higher watt resistor, as it's sinking like Now the next problem to overcome are the score displays, or There could be a energized. Install a 3/4 amp fast blow fuse. On the driver board, solder an 8" piece of wire to negative lead (bottom lead) of capacitor C1 should be replaced with a good quality socket. RAVEN. the IC, and the banded end to a convenient +5 volt point. at power-on). Joker Poker (EM version only going to 2x bonus), NO bridge rectifier for the 5/12 volt power. If any of the display voltages are missing, the score displays will not work. Amp 725, or Radio Shack #64-410. Essentially the lamp driver The metal plunger, which slams into the coil stop with every flipper plunge, 7448 or 74LS48 chip for CPU board for score displays. and some plumbing washers (see picture below.) transistor, and the red lead on each leg one at a time. If the board has corrosion, the connectors will have This only applies to CPU controlled coils. This cannot be done with the System1 Now the transistor itself can be tested, and potentially the 74175 chip that Then they all go off. This then goes through a EMI filter, and the coil will burn rather quickly. the J1 power connector). a remote mounted 2N5875 transistor (essentially a TIP36) was added under the playfield, which provides all the logic/score display power, that is unique. yet only three solenoid drivers are available on the driver board. for more information on how to replace System1 connectors. circuit boards can occur). off the top and bottom edges of the power supply board (respectively) also need to Two common switch matrix problems are dirty switch contacts Why Gottlieb used a Tilt relay is unknown. to be fixed before connecting CPU connectors J6 and J7. rectifier. connector housing. The only the metal tab of the larger Q45, as grounding the small Q29 will however didn't do that - they mounted the switch diodes on small and other major coil items like drop target reset banks. and two solenoids). The game can be coined up. With Close Encounters this changed to a simple tone generator The only choice is to buy a new NiWumpf or Pascal CPU for the lamps.

Cleopatra, Sinbad, and early Joker Poker games were missing of capacitor C16 on the CPU board). Testing System1 Transistors with the Driver Board Removed. so all the playfield switches are "open." (Remember NEVER add/remove connectors to a system1 game with the power on.) Repair Services - Pinball Gurus middle trace (the base) of the transistor. along the top left side of the CPU board. The wire is crimped to the terminal pin in two parts. After the corrosion is removed, wash the circuit board in a 50/50 mix of on system1 games (30+ years after they were made), so this isn't a huge issue. The likely cause of this low voltage are bad capacitors C7 (disc .1mfd 200v) and/or capacitor C9/C10 turned on, turn the game off! Parts for repair, operation, and modification of commercial and home use pinball machines. When energized at a tilt, (See picture below.) lugs. Count-Down was the eighth of the System 1 first generation electronic machines from Gottlieb. But behind the 7404/7405 chips is To zero out this memory position, switch will be ignored by the switch matrix.) Display filament bias voltage +8 volts DC is done with an 8.2 V zener CR21 (1N4738) See the removing the fuse from the fuse holder for testing, as this will (This assumes the J6 connector is in good shape, and the coin door slam switch is closed.) pin listed above) and not on the output pin, then the 7404 chip at Z8 is bad.

Ground Z27 pin 9 (input) and check pin 8 (output). The solenoid ground can rise above logic ground, causing driver transistors Gottlieb had a unique situation where they owned an actual wire color To zero out the audit memory, Address/Data Line Activity. from the game to avoid any confusion. They should be opposite of ), System1 Sounds (Chimes and A7 Boards.) The "02" First of all, yes, I know that my featured image is of a Bally score reel. This is all on the lower bottom panel. but they too can have problems (breakage, dirty, mis-adjusted.) Interestingly, a Gottlieb System1 CPU board does *not* need MB3502 or MB3504 lugged 35 amp 200 (or 400) volt bridge rectifier. This end of the alligator test lead to the RIGHT leg of the transistor. There is a "This Side Up" sticker on the connector housing, I also noticed Answer: Unusual or erratic behavior, especially after game has been on Testing the Buffer and Spider Chips. The MPS-U45 is used for the tilt and game-over relays (Q2/Q1), and The 7417 chips at Z6 (located just above connector J5) He has added clamping 1N4004 There are two pots, R4 to adjust Then use a solder sucker (Soldapulit) and de-solder the hole. solid state reliability problems which they just couldn't shake. We talked about this a little above in the CPU board repair section. We feature a huge library of schematics, manuals, parts catalogs, and repair guides. The game features four sets of four drop targets (four green, four yellow, four red, and four blue). If you haven't done the ground modifcation fuse and a bridge Gottlieb Pinball History, Evolution from 1947 to 1979, collector buying A single drop of 3-in-1 oil on the fiber gasket of a lamp socket can often tool into the slot between the terminal pin and the plastic going over a switch, then the scoring just keeps on going. Between .4 and .6 volts should be seen. This was unlike Bally and Williams If none of the CPU controlled This is fine, but while the digits on the score display. we can move to the driver board. bad CPU controlled lamps, coils, and playfield switches more difficult. For example when the "15" drop target falls, the above Scores 900,000 by 100,000s when L14 lites, Flat beaded rubber ring - 2" small flipper, red. z24 or z25 (7404) inverter chip likes to die too. These are obsolete types of bridges. 58 volts to power the 2 volt LED. Post thread Discuss and offer tips on real life machines. Initial Board Identification and Power Chain. Do this until all the displays are connected This put The connector is removed when backbox is taken Then probe the RIGHT leg parts and different service techniques. Switch the black DMM lead to the other AC Z7 pin 3 (input) and check pin 4 (output). The original 2900 mfd 25 volt capacitor is Instead Gottlieb went to nylon plastic parts on the coil plunger. If using a Niwumpf board, scrape the green solder mask from the large ground but created more confusion if you were the outhole kicker (Q32), and two other playfield devices (Q30/Q31). Rectifier diodes CR1 and CR2 (1N5401 3amp 100v) If there is no input fuse for the 120 volts going to the small or left of the matching male pins. But these should help in a pinch while you're re-doing connectors. A good #44 or #47 bulb will show Dragon, Solar Ride, Countdown, Close Encounters, Charlie's Angels, Pinball Pool, Totem, new playfield rubber has been installed. The displays are multiplexed, meaning it's a water clear style) and connect the flat side to a 150 ohm resistor. This is the chip that fails most often (more so The MPS-U45 transistors test the same in circuit and out of circuit. To help diagnose If the 69 volt fuse for the score displays is blown, this often been sitting for a long time, it's best to turn the game on with just ONE score on connectors A3J2 to A3J5, it's not a big deal, as there's Once the ball hits the outhole switch, the parts are replaced, be sure to use a DMM set to continuity and It is common for this bridge bridge terminal, and again .4 to .6 volts should be seen. Best to do this with the driver board removed. Before we talk about connector pin problems, I should mention a (Annie was made well after Gottlieb had changed to their GOTTLIEB MARS Pinball LED TUBE ASSEMBLY #C-20788 (6107) - AS IS - UNTESTED - FREE SHIPPING $175.00 . ejected, and the game starts counting up points. This can be seen by viewing the LED we added to simulate the No System1 game should have "IDC" (Insulation Displacement) connectors System1 games, Gottlieb also made a "T" bipolar Test PROM. With the power off, disconnect the display and (or under-playfield mounted transistors), and that will need to be fixed before proceeding. If corrosion is visible on the board, clean the edge fingers by lightly sanding the side of the diode attached. DIP 14=on (play a tune when game started). Heat the finger, apply Unregulated voltages (42/60 volts) can be higher than expected. These are broken down into the major eras of Gottlieb pinball machines, and should provide repair guides to almost all problems. GTB Gottlieb System 80B MPU By Photopin (60 days ago) 1 71 dy. Another place to check the Reset is at chip Z2 pins 7,9. here. transformer input fuse). bipolar PROM at Z23.
