$4250 incl shipping TM 201603 Chch
Supposed to be in ‘Great Condition’ but unplayable as delivered
- Has crane decorative mod
- Has Deadworld mod & L1AT rom
- Has later style police LED flashers on left/right ramp entrances
- Playfield is excellent condition
- Some plastic ramp repairs but seem ok and not obvious from players position
- Has topper, with a strip of colour changing LEDs reflecting on to it for a pretty good effect
- Left flipper coil has been abused including copious amounts of hot glue
- Left top flipper coil has been abused including copious amounts of hot glue
Issue JD-20160312 multiple problems as delivered
- Crane was not bolted in
- Bolted in and aligned using set screw
- Deadworld loose & misaligned
- Fixed
- Left flipper EOS switch non functional
- found loose common earth wire under playfield and soldered it back on
- Drop targets unable to be raised by coil
- TEMPORARY fix: Locking clip lost so Opto PCB tilted and is getting hit by coil activate drop target lifting plate, just tilted PCB back to parallel
- A few ramps etc loose here and there, tightened as each is found
- Gets stuck with multiple balls in shooter lane
- Filed divots from ball through
- cleaned trough sender & receiver LEDs but still faulty
- resoldered trough Opto sender PCB
- still faulty so replaced sender LEDs & current limiting resistors (Jaycar part ZD1945 works fine), reduced current slightly on feeling slightly more modern (hopefully) LEDs more efficient
- adjusted shooter lane microswitch
- tightened shooter coil & replaced sleeve (Did left side at same time
- tightened trough coil & replaced sleeve
- Trough issues resource: Http://www.pinballrebel.com/game/pins/ij2/shop/Trough.htm
- Both flippers activated = resets
- Replaced BR1/2 (GBPC3504W) C5/11
- Both main flippers way too much shaft end play
Issues as delivered NOT yet resolved:
1 GI strip out. A fuse is loose on power PCB, Wriggling fixed it for now(Resoldered during Issue JD-20180324)Drop targets unable to be raised by coil: need permanent fix(Added missing circlip during Issue JD-20180324)
Other improvements
It had maybe 5% leds, replaced most of remaining GI & Controlled, as well as all flashers
Dirty playfield, gave it a cursory clean, pending a full future strip down
Cleaned those Opto pairs I could easily get to
Issue JD-20180320 Multiple issues – resolved
Observations:
- On power up a solenoid somewhere fires a few times before going quiet
- On game start launches multiple balls
- On game start continuously launches balls
- On game start flippers non responsive but work ok through Solenoid tests
Secondary observations after commencing investigation:
- Opto trough transmitter board doesn’t have LED8 (Power indicator) on
- IJ manual shows as supplied from unregulated +12V
- On Power Driver Board
- Led1 is indicator for +12V regulated supply & is on as expected
- Led7 is off, is +12V unregulated supply:
- F116 visual check and does not appear to be blown
- Nudging related Fuse F116 intermittently activates Led7
Conclusion/Action 1:
- Conclusion: Power Driver Board Fuse F116 bad joints
- Action: Resoldered ALL fuse holders on the Power Driver Board
Issue JD-20180324 Left shooter (Missile launch) weak, leaving balls in left shooter lane – NOT RESOLVED
Observations:
- Assembly is part A-16936
- When playing when ball goes into left shooter lane, shooter appears to be too weak to send ball out
Secondary observations after commencing investigation
- Solenoid test activates this shooter weakly but also left lower flipper strongly
- Left Shooter is: Solenoid 04 Brn-Blk/Vio-Orn
- Left lower flipper is: Flipper 03 Blu-Gry/Gry-Yel
Solution
- Wiggled the coil connections and problem went away so resoldered coil wires
Update 20190802 Still weak at times
Investigation:
- Spring is manky / bent, part no is Solenoid Spring 10-135
- Noticed that the kicker appears almost offline to the ball groove so loosened bracket screens to playfield and realigned slightly
Issue JD-20190802 Top right flipper no return – Resolved
Observations: Top right flipper appears to be sticking up intermittently, half drops sometimes, a ball running over it also can cause it to drop somewhat
Investigation 1:
- Doesn’t really look like coil is staying fully on so will assume is mechanical for now
- Spring is intact
- EOS switch position looks fine
- Removed coil:
- No mushroooming
- Replaced cool sleeve
- Shaft end play is minimal but not tight/binding left for now
Solution Attempt 1:
-
-
- Plunger is mushroomed – ground down for now
- Replaced coil sleeve + spring
- Flipper shaft end play was set very loose – made adjustments
- Checked and adjusted EOS switch (was testing ok)
-
Issue JD-20191025 Top right flipper hard on – interim resolution
Observations: Top right flipper sticking on hard as soon as:
- Start a game
- Enter Tests -> Solenoid Test (and close door to enable door interlock)
Investigation long version:
- Tests -> Flipper tests no issues so not driving transistors etc
- Tests -> Solenoid Test, Flipper turns hard on hard on
- Flippers are activated by 2 stage flipper plunger (Opto assembly)
- Checked and in Tests – Solenoids and flipper plungers are live and activate selected flipper
- In Switch tests, left flipper button I can separately activate lower then upper flipper, but right flipper only activates lower flipper switch
Investigation short version:
- From the above we see that Tests -> Switch Edges shows F6 Upper Right Flipper Opto as locked on, so that is the issue
- Unplugging Right Opto PCB J1 F6 goes off in Tests -> Switch Edges
- Right Opto PCB is A-16384-1
- F6 is Black/Yellow, Opto PCB J1-1 is Black/Yellow so SW1 is F6
- Removed Opto PCB, and resoldered all joints still no go, Opto1 still not functioning
- Opto part:
- is an obsolete Senisys S-1865 (Mexico 9338) NPN Slotted Optical Switch
- Fairchild QVE11233 is listed as a compatible replacement
- Also OPB804
Temporary fix:
- Replaced with a Fairchild H21A1 Opto switch that we had on hand
- BUT: opto height is incorrect so even after raising the opto in the PCB it activates a little too soon:
- Assuming QVE11233 is a physically compatible part specifically the Opto CL:
- QVE11233 Datasheet: Opto CL is 9.9mm up (from PCB) (Height = 11.68mm, CL = 1.78mm from top)
- H21A1 Datasheet: Opto CL is 7.32 to 9.15mm up (Height = 10.7-11mm, CL = 1.85-3.38mm from top)
Future: Buy drop in replacement:
- OPB804 Datasheet: Opto CL = 9.89mm up (H = 11.68, CL = 1.79 from top)
- UPDATE: Suggestions are that the original is a Schmitt trigger device: Forum
Todo (non playfield)
Power Driver Board: Resolder/repair fuse holders for GI circuit(Resoldered during Issue JD-20180320)- Power Driver Board: Replace all BRs & associated large caps (5V done during Issue JD-20160312)
- Power Driver Board: J120 is a bit munted, needs replacing one day, has trace jumpers on the underside as well so trace damage
Todo (playfield) interim to full strip
- Replace left flipper coil (FL-11629 Blue 50V)
- Replace top left flipper coil (FL-11629 Blue 50V)
- Remove enough to get to remaining Incandecesents that are under the playfield
- clean what can be cleaned during the above
- replace captive balls with something interesting
- Its a dark machine, needs much light added
