The 68B09EP places a data bit pattern on the data bus. So many shorts - from the GI; lamp matrix; flashers; or solenoid wiring can destroy the driver. The MPU can also (and needs to be) jumpered for different ROM sizes. Pins 3 and 4 are ground for the magnet board under the playfield. Use your DMM to test the bridge rectifier and to "buzz" between the solder joints at the cap and the appropriate legs of BR5. The pages were printed on white-colored paper. Normally lit. If the display image has a "plasma" affect or a "cloudy" look, it's a good idea to test the input voltage to the DMD Controller board, as depicted in the animated image at left. Be aware that an additional fault may still be present on the playfield. If your game's audio is just a bit scratchy, and these caps have not been removed, you may be able to improve audio quality by removing them. Clip the black lead of your DMM to game ground, or tuck it under the backbox ground braid. When you enter the “Creative Mode”, you unleash unlimited resources and in the “Survival Mode” you will put your craftsman skill to the test as you fend for your life. Use your imagination to shape the world, well, the LEGO world! Fatigued connections between the ASIC on the MPU and it's chip socket. All RAM ICs need to be replaced at the same time for this configuration to work. This can be easily corrected by removing the lamp board from the game and reflowing the solder on the pads. A 2N5401 transistor can handle a comparatively small amount of current. If it's an iC capacitor it is likely OK. Another place to examine for fractured solder joints is on the solder side of the board, where the LM323K (WPC-95: LM317) 5VDC regulator is placed. We are looking for an "open" or a "short". This version of the parts catalog included 4 pinball titles and 2 shuffle alley titles. Q2 is in a TO-220 package (like a TIP-102) and has a small heat sink attached. A dremel tool with grinding stone works great for this. to rule out a defective coupling capacitor. Follow these steps to determine if the switch matrix problem is on the CPU or somewhere in the game wiring. Remember, you are working one-handed, so this becomes a necessity. Switch Edges Test presents an 8 by 8 switch matrix grid with one or two switch columns outside of the matrix. If this happens in WH2O, Big Foot will not turn his head during game test at boot up. Flash lamps don't create the same reverse voltage spike and hence, don't require a clamping diode. Possible failure points are: If the volume suddenly jumps to full volume and control of the volume via the coin door buttons does not work, check C18, a 47µF 35v axial electrolytic capacitor. This failure is caused by a poor connection between the ASIC on the MPU board and it's socket. The cause of this failure is not the display or the dot controller. Unplug all connectors with red or yellow wires leading to them. These opto-isolators communicate flipper switch closures for pre-FlipTronics games. The smaller wire must have a solid connection back to the driver board. A video demonstrating this technique on a Data East MPU can be viewed here. This was a supplementary parts catalog that updated pages and added titles to the previous version of the red parts catalog. AC voltage is rectified by D15-D18 and smoothed by C10. you probably will find at least one that is loose - this can contribute to reset issues. Anything over 1VAC indicates a failed/failing filter capacitor at C5 which should be replaced. The WPC-95 A/V Board was introduced, along with the WPC-95 system, with Congo and was used through the end of the WPC game system run (Cactus Canyon). ROM Size Generally, the problem is going to be a blown transistor, or rarely, a failed 74ALS576 latch. The output side of U15 can't be tested effectively since that is the processor/ASIC data bus and should be constantly and irregularly changing states. Electrolytic capacitors do not last forever. The ASIC must be oriented correctly when installed. Simply clip the caps from the board. Placing the black lead on each of the AC legs in turn should yield a reading between .5 and .7 volts. The FlipTronics board rectifies the AC power via an onboard bridge rectifier. This LED is toggled from pin 35 of the ASIC (DLED signal). Reflowing the solder at these joints is prudent. Finally, the diode legs must not be connected to any of the other wires or terminals of the switch, or the switch will funk up the switch matrix. The designer switched to a remote battery holder, located on a daughter board that clips to posts on the lower half of the board. The output of U1 forms signals T0 thru T4, which enable the TRIAC circuitry. Shown on the right is another shot of the damage caused by a leaky cap at C2. Note also that DCS and WPC-95 A/V boards may reset independent of the MPU. In “Breath of the Wild”, our hero, Link, awakes after being asleep for over 100 years, just in time to fight the evil Calamity Ganon, a godlike creature, who pretends to destroy Hyrule and then the entire world. A difference of .1VDC is enough to warrant examination of the connectors between J114 (WPC-95: J105) on the Power/Driver board and J210 on the CPU board. Presumably, Williams did this to provide flexibility in voltage levels used to drive a special solenoid. The voltage is used to power the flash lamps. 10 - U10-U12 RAM error. Service Credits/Escape (referred to as "escape" here). This was caused by the blown trace. A/V RAM are, in fact, U9-U11. The WPC-95 system implementation moved the cabinet flipper button and EOS switch sensing from the FlipTronics II board to the MPU board. It shares the port with the Fliptronics board and the display board. The output of the 2N5401 turns on a TIP-102 transistor. D20 will also indicate basic issues with the MPU by blinking as such... Two blinks - problem with the game RAM (or accessing the RAM, i.e. This LED should light when power is applied, then after about 1 second, go off and stay off. When a flash lamp drive is used, a diode must be added to the circuitry, as was done with the Terminator 2 single drop target for example, as the power/driver board doesn't include this diode. The connector on the upper left carries the signals for the photo-transistors. While diodes seldom fail, sometimes the pounding environment that flipper diodes must live within causes solder joints to fail. If you still measure high, then the pin isn't being grounded correctly. Compare results to a known good amp of the same type. For its time, this was an extremely fast device (40MHz), and is capable of providing all of the sound processing needed in a WPC pinball machine. D7-D10 replaced BR2. To do this, the CPU uses a zero crossing signal on the driver board keyed from the AC that feeds the 5V circuit, diodes D3 and D38, and the LM339 at U6. Mad Amusements offers a stainless steel version of a trough sleeve insert. The (not) Q signal of each 74LS74 enables one of eight TIP-102 Darlington transistors (Q83 thru Q90) that provide the actual path to ground (through a .22 ohm 1 watt resistor) for the 18V lamp matrix power. Either the power circuit fuse has blown or there is a discontinuity in the power wiring from the driver board to the coil. NVRAMs in the standard DIP package are becoming hard to find but several pinball parts vendors sell a nice 6264 replacement NVRAM based on these parts. There is no real need to desolder them. Next ensure that all speaker connections are solid. You are Bayek, protector of Egypt, whose personal story will lead to the creation of the Assassin’s Brotherhood. The FL-20867 flipper coil is thought to be between an FL-11722 and an FL-11630 in strength. The signals pass through the board from component side to solder side at U9. This loosening can cause mysterious behavior and resets. Subsequent games until the WPC-95 board set debuted used the FlipTronics II board. Both devices are 74LS175. If the coil pulls in, then the path to ground has been proven and the failure is likely the TIP-102 itself. The test lamp should flash to indicate that the column driver is working. That dust is conductive and may cause odd coinage issues. Use an oscilloscope to probe pins 9 and 12. Before you begin any work on the DMD controller board, perform the above test with the DMD display power disconnected. Worse, the heat in the connector will turn the grease to gunk. Failure of the associated .22 ohm 1 watt resistor in the path between 18VDC lamp matrix power and ground (R150 for example). Dow Corning #4 grease can't help them. J903 Pins 1 and 2 supply 50v for the magnet board under the playfield. Corrosion on the MPU that might have compromised the enable signals, as seen in the picture at right. If measuring shows 0 VDC, either the batteries are dead, or D2 has failed (see above). Im Buch gefundenDer „Klassiker" der Bildverarbeitung liefert eine fundierte und anwendungsgerechte Einführung in die wichtigsten Methoden und in ausgewählte Verfahren. The pre-DCS sound board uses 1uf tantalum caps in the amp circuit. That is, the 4N25 that should report a left flipper closure actually reports a right flipper closure, and vice-versa. Audio Amplifier This can result in too much AC "ripple" feeding the amp as well as DC output to the speakers, which they do not like. Also, you can play most of your Wii games as well. The picture gallery below provides an example of correct wiring for different types of switches. If not, socket and replace the ULN2803. The image at left shows two amps from the same WPC-95 AV board that were blown when the non-ground speaker wire broke free and touched the speaker housing. The owner's game manual is a handy resource to have for general game operation, game settings & diagnostics, switch & lamp matrices, fuse lists, circuit boards and parts, playfield assemblies, some basic schematics, and wiring diagrams. Depress the switch. When the triac is turned on, the GI lamps glow. This LED isn't very useful as it will flicker as power consumption by the game fluctuates. When this capacitor is no longer smoothing the rectified AC well enough to produce a clean 5VDC, the voltage may drop below the threshold enforced by the watchdog circuit on the MPU (an MC34064 at U10). WPC-089 Power/Driver Board GI Buzz Diagrams provided by Sascha Voskuil. For WPC power/driver boards, the lamp matrix TIP-107 transistors can also be checked using this method if the black probe is touched to the 18V test point on the right edge of the board. :-). Re-examine J205 and the surrounding area of the board for alkaline damage. Repeat the test for the pins 2 through 9 on J133. When the switch closes, it shorts the 12V to ground and the comparison at the LM339 then indicates to U15 that the switch is closed. Before you go too far diagnosing the hardware, if your WPC game will not dim the general illumination, make sure that Standard Adjustment #25, "Allow Dim Illum. The ultimate motor racing experience has return to shape the future of motorsports in gaming. If after repairing the lamp board divots, reflowing the header connectors, the lamp socket is still completely intact, (the contacts do break off of the socket sometimes), and the bulb is good, suspect that the diode associated with the particular lamp may be bad. Note: The EZ-SBC PSU5 has one side affect that may be annoying. The auxiliary 8-driver board sits in the top right of the backbox in a handful of WPC machines. Insert one probe of your DMM (either one) into the rear of the female connector position with the same wire color as noted earlier. The colored wire connections for this era of WPC game are yel-wht connected to pin 1, yellow connected to pins 2-6, yel-wht connected to pins 7,8, 10, 11, & 12. Measure DC voltage at TP2 (WPC-95: TP101) on the Power/Driver board. Most of the time, the drive transistor on the driver board has shorted internally and is acting as if it's been turned on. The additionally columns are for dedicated switches. In the picture at left, a shorted TIP-36c was replaced. The multi-award-winning Skyrim Special Edition put you inside the fantasy with life-like detail. BR4 recitifies AC power for the flash lamps. This is an indication that this connector should be repinned. The data bus is extended to the power/driver board via the interboard ribbon cable. The WPC system, like many pinball machines, uses a switch matrix to read the switches. When closed, the game immediately stops, and the display fills with diagonal lines, as pictured at left. Don't buy them unless the supplier calls that out as the brass version looks the same but is only rated at 5A. Later units used a 12 pin connector on the power source metal box located inside the cabinet floor on the right just inside the coin door. Should the through-hole of the bridge leads be cracked or otherwise damaged, use the "solder stitch" technique noted above or install jumper wires between the DC outputs of the bridge and the terminals of C5. In the picture at left, the coil that actuates the "Bridge Diverter" on the game Twilight Zone, is touching the coil bracket on one side. You should see the signal transition to low. Most of the time, F114/F115 will be found to be just fine. Also, if during game play, points are scored when the switch closes, clearly the switch is being made. Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu. All images provided by Chuck Sanderson, CP Pinball. If other products are used, investigate carefully to ensure they are a proper dielectric grease suitable for high temperature applications. It is located just to the right and just above the driver board in the backbox. This can be corrected easily by simply reflowing the solder at the joint. Forum Themen Beiträge Letzter Beitrag; Guten Tag lieber Besucher! If at "normal" volume levels and the heat sink is so hot that you can not grip it, failing tantalum caps should be suspected. If not, there is a discontinuity in the wire between the direct switch and J205. After replacement of bridge rectifiers is made, it's not a bad idea to mark the replacement date. It is located at the bottom edge of the board near connector J122. This board was used only on "The Shadow" to provide lamp matrix diode isolation for the 4 "Ring Grain of Wheat" lamps. Nintendo 3DS games work on the Nintendo 3DS XL, Nintendo 3DS, 2DS XL, and 2DS. Typically, circuitry on an "opto switch board" interprets the lack of 12VDC using an LM339 comparator, and indicates that the switch is open. But if the game is resetting, it is probably best to replace C31. This power is used for all coils in the game. Nintendo 3DS and Nintendo Switch are this brand’s leading consoles and here is information about their latest game releases. Excellent repair information for this board can be found here and a possible replacement for the overloaded non-polarized capacitors here. The ground braid in the head is a good place to pickup ground at this point. Isolate the problem to the MPU or to the game wiring/diodes/switches. Please note when testing these boards, the right flipper board has to be plugged in for the left board to function. The Switch Matrix - assorted switch problems. There are three known variants of the WPC-89 driver board: A-12697-1, A-12697-3, and A-12697-4. New weapons, new abilities and the never-ending dose of deadly enemies return to chase our heroine once more. The signal should measure high (or about 12VDC with your DMM). Outgassing displays look very much like a display that is being overdriven by too much voltage. This is possible on WhiteWater, Dr. Who and Bram Stokers Dracula at least, and may also be possible on other games. If the socket works, the original socket may have been the problem. The serial port is rarely populated. This calculation represents the nominal voltage delivered by a single AA battery, times 3 (batteries), less a typical .6 VDC drop across diode D2. AC rectification and smoothing for 70VDC solenoid voltage, AC rectification and smoothing for 20VDC flasher voltage, AC rectification and smoothing for 18VDC lamp matrix voltage, AC rectification and smoothing for unregulated 12V supply, AC rectification and smoothing for 5VDC flasher voltage, Power control for pre-FlipTronics flippers (not on all boards), Sense optos for pre-FlipTronics flippers (not on all boards), Power control for 5 6.3VAC GI channels using four-sector triacs, Rectifier and fused power supply for +/-16VDC amplifier power [check - WPC was 35V? There is a time and place to use this type of product, mostly as a preventative measure on newly replaced contact surfaces. Indicates presence of regulated 12VDC. Note that sometimes C2 is installed on this board and sometimes it is not. Repair in the area is tricky.
