- 520-5050-02
- 520-5050-00
- 520-5050-03

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.

- 520-5076-00
- 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:
- 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 it is connected to.
4.3 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.
- 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.
4.4 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 | ||||||
4.5 Power Supply Issues
- If you have a low +5v, a 'shotgun' approach would be to replace the bridge rectifier (DB1, CM3501), C2 (100uf 25v), C1 (1000uf 25v) and TR5 (2N6057).
4.6 Display Driver Board
4.6.1 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.
