  • 520-5075-00

Used on the large 192x64 dot matrix displays on games Maverick through Batman Forever.

3.4 Sound Board

  • 520-5002-0x series
    • 520-5002-00
    • 520-5002-02
    • 520-5002-03

    • 520-5050-00
    • 520-5050-03
  • 520-5077-00

This board is similar to the 520-5050-0x series. It was redesigned to allow up to four 27040 EPROMs for voices and sound effects. It has a different pre-amplifier design than the 5050 series, but uses the same MB3730A power amplifiers.

  • 520-5126-02

This board is very similar to the 520-5077-00 design. The power amplifier section was redesigned. It is reported that it is interchangeable with the 520-5077-00.

    • 520-5033-03
  • 520-5070-00
  • 520-5076-00
  • 520-5080-00

4 Problems and Fixes

4.1 Fuse Clips

Data East used fuse clips on circuit boards as opposed to fuse holders. These clips are prone to cracking and causing intermittent connections. These clips cannot be repaired and should be replaced when cracked. The clips do have a correct orientation, when installing them make sure the "tabs" on the portion that grasps the fuse is oriented outwards.

Fuse clips are located on the Power supply, Playfield Power Board, and Solid State Flipper Board.

4.2 Power Driver Issues

Quickly test the TIP102/TIP122 transistors (Q8-Q13, Q23-Q30, Q39-Q46, Q72-Q79) on the MPU:

  • Turn the game OFF
  • Set your DMM to Ohms/Continuity buzz
  • Attach the black lead to one of the metal grounding straps (crocodile clips are helpful here), there should be one in the backbox you can use
  • Touch the red lead to the metal tabs of the TIP122/TIP102's
  • Any that read 0 Ohms (ie are shorted) are bad and will need replacing.

You may also need to replace the predriver transistor (2n4401) that the bad transistor is connected to. It is also wise to check the wiring and the coil before powering back on, otherwise you may blow the transistor you just replaced.

See How to test a coil

4.3 PPB Board Issues

Common issues include:

  • Burnt GI connector
  • Dead TIP36C

4.4 Flipper board Issues

The TY-FFASI board located in the bottom of cabinet is prone to a few failures. It's a fairly simple circuit so fixing it is normally quite easy. It supplies 50v to the flipper for 40ms then switches to a holding voltage of 8v, so it doesn't burn the coil out. You should see a red LED flash when the flipper buttons are pressed.

To test the flipper board:

  • Remove the board from the cabinet (it's much easier to work on)
  • Check all the fuses on the board, 4 in total (2 power, 2 hold)
  • Check all transistors using a DMM
  • Check tracks for continuity and corrosion
  • Replace board back into cabinet and power on game
  • Enter Diagnostics (so power is sent to the flippers)
  • Check voltage at coil lugs (Should be ~50v DMM set to DC, black lead on GND, red led on banded side)
  • Press flipper button and check hold voltage (should be 8v)
  • Check power/hold voltage on flipper board (black lead on GND, DMM set to DC, red probe on CN2-6&7 8v hold, CN2-8&9 power)

If you have no power voltage on CN2-8 and CN2-9, check the PPB board J7-1 and J7-5.

If you have no hold voltage on CN2-6 of the flipper board, check the Power Supply board CN1-10 and CN1-11. If you have no hold voltage on the coil lugs, check the hold fuses on the TY-FFASI board.

From Jurassic Park onwards, an EOS switch was added back into the design. If the hold voltage is broken and the EOS is badly adjusted, you may experience 'machine gun flippers'.

4.5 MPU Issues

Data East CPU Board LED Flash Sequence

Much like the Williams System 11 CPU, the Data East CPU performs a basic diagnostics procedure and produces a series of LED flashes to indicate potential boot issues. The CPU automatically tests the PIAs, RAM and EPROMs at each boot.

With all tests passed, the LEDs illuminate in the following sequence at power-on:

  • The PIA and +5V LEDs illuminate immediately
  • Approximately 1/2-second later the PIA led is turned off and the Blanking LED illuminates
  • +5V and Blanking LEDs are illuminated until the game is turned off.
  • If a failure is detected on major board components, the PIA LED will display a flash code:
PIA LED Flash Sequence
PIA LED Suspect Component
Stays On One of the 6821 PIAs
Flashes 1 Time 6064 RAM at location D5
Flashes 2 Times EPROM at location B5
Flashes 3 Times EPROM at location C5

4.6 Power Supply Issues

If you have a low +5v, you'll experience game resets, especially when pressing the flippers during multiball. A 'shotgun' repair would be to replace the bridge rectifier (DB1, CM3501), C2 (100uf 25v), C1 (1000uf 25v) and TR5 (2N6057) on the power supply board.

4.6.1 PSU 520-5047-01

4.6.2 High Voltage (HV) at the DMD display

4.6.2.1 No +68v is found at the DMD display

Warning Be extremely careful not to touch anything when working on live High Voltage (HV) circuits.

Assuming it's not the transfomer, connectors or fuses then you should be able to measure a +DC High Voltage (HV) at the banded side of D5 with respect to GND.

If no voltage there, suspect fuses and then test D5 on the diode setting and replace D5 with a 1n4004 diode. Also test, and replace D7 with a 1n4004 diode at the same time for good measure as it's a penny part and probably stressed. Same procedure although it rectifies the a -DC HV.

Measurements are with respect to ground. You should now have a HV +DC reading at the banded side of D5. Test for +68v output. You should also have a HV -DC reading at the non-banded side of D7. Test for -100v and -98v DC output.

Do not be concerned if measured voltages are not exact without a DMD connected, they will read lower under load. It can also be that the DMD display itself is faulty and taking down the PSU.

Capacitors C10 / C11 are important, if you can't test then replace them. Especially if it looks to bulge at ends, old capacitors dry out and then fail. C10 and C11 are both 100uF @ 200v. You should be able to use 150uF at a higher voltage for these, so 150uF @250v is fine.

Observe the polarity of the capacitors you remove and mark with a Sharpie if not already indicated on PCB mask. This is very important for Electrolytic capacitors which have a polarity!

D5 / C10 are for the +68v HV DC to the DMD Display. D7 / C11 are for the -98v and -110v HV DC to the DMD Display.

The circuit for +68 voltage is comprised of components under CN5 / CN6 of the Power Board (PSU).

Check values of the above resistors. Any out of spec. (or showing open) will need to be replaced first. Test DMD again. Then replace the 1N4760 68v and 1N5228 3.9v zener diodes and test DMD again. Then work through the transistors, replacing TR1 then TR3 test the DMD.

4.6.2.2 No -100v is found at the DMD display

Follow a similar procedure to the one above. The plus and minus HV circuits are nearly 'mirror images'.

A missing -98v DC output only while reading -100v points to D11 (1n4742 12v zener diode) or R14 (4K @ 10W ceramic resistor) as faulty. Test resistor value R14 and replace if open or out of spec. Then replace D11 observing banded side for polarity.

† The MJE15031 is a heavy duty version of the MJE350 (TR4)

Check values of the above resistors. Any out of spec. (or showing open) will need to be replaced first. Test DMD again. Then replace the 1N5379B 110v and 1N5228 3.9v zener diodes and test DMD again. Then work through the transistors, replacing TR2 then TR4, test the DMD. Get the -100v output working first, then go after the -93v circuit.

4.7 Display Driver Board

HV for the DMD displays is on the PSU board.

4.7.1 Two 27020 EPROMs vs. single 27040 EPROM

Some games such as Lethal Weapon 3 and Star Wars sometimes used two 27020 EPROMs at locations U12 and U14. If one ROM is used, R11 should be open (nothing installed). If two ROMs are used, R11 should be jumpered.

5 Game Specific Problems and Fixes

5.1 Lethal Weapon 3

The right flipper button spring can bend out and touch the legs of the shooter coil, causing all manner of strange behaviour.
