Pinball: The Getaway II

2014?

Not looked at until 20180221

  • Right slingshot: broken link, replaced
  • Top flipper sticking replaced coil sleeve & spring
  • Right pop bumper not firing, adjusted leaf switch
  • Main fuse blowing: replaced inrush limitor, spike arrestor, EMI filter (Had to use Jaycar part), note it was the EMI filter that was blowing the fuse!

Gone to GH NZ$2500 as a gift

Pinball: STTNG Star Trek The Next Generation

Bought 2016 sometime


Observations:

  • The cleanest best condition machine I’ve ever seen, immaculate under the glass
  • ColorDMD display
  • Power driver board is a Rottendog replacement (full size, all through hole), laid out like original except BR’s are separate diodes.   It seems pretty nice.

Reminder re ball locations on startup:

  • STTNG is a six ball game, BUT on startup it relocates the 6 balls so that:
    • 1 sitting in Left VUK
    • 1 sitting in Left Gun VUK
    • 1 sitting in Right Gun VUK
    • 3 in through
  • There a 2 switches each in both Left & Right Gun VUK’s
  • There are 4 switches in Left VUK

Issue STTNG-20180120: F112 Fuse blown

A guest was playing and said balls had disappeared. They had.

Looked at Power Driver Board, has separate unlit 50V indicator LED as well as nice test points.  The 50V circuit is out.

From WPC Schematics manual

  • J102 supplies BR3 via F112
    Output of BR3 (50V DC) splits to pass through:

    • F101, F102 then flipper circuits via J109, J110
    • F103 (Continuous), F104 (Lo power pulse), F105 (High power pulse) then to solenoids via J106, J107, J108

Checked fuses:

  • F112 is blown, no others. It had a 5A fuse.  manual says 7A but some people do seem to put 5A in instead as thats what they have.  I won’t simply assume its under fused until I check for shorts

Trouble shooting step 1:

  • Reseated J102
  • Disconnected J106, J107 (J108 is NC on this machine)
  • Replaced F112 with 5A fuse
  • Powered up machine

Result:

  • 50V DC led is on
  • Did all Flipper tests no problems

Trouble shooting step 2:

  • Reconnected J106. Hmm I can’t see J106 in the solenoids table
  • Power up machine

Result:

  • fuse still good
  • Ran all solenoid tests.  No solenoids fired.  Still not sure what J106 is feeding

Trouble shooting step 3:

  • Reconnected J107
  • Power up machine
  • Machine plays ok

I will assume is underfused and takes a particular combination to blow F112 at 5A

Update (20180203) Machine is playing ok with regards to this issue)


Issue STTNG-20180203: Left VUK firing but not ball not sucessfully kicking out (Weak VUK)

Observations:

  • This is a very busy VUK, in near constant use, so is a high wear assembly
  • The coil mounting bracket has a missing stud (Part = A-16858).  A fair indication that has been worked on previously
  • The plunger is sticking slightly when retracted fully (by the spring)
    • The coil sleeve on this coil extends longer than those on the Left & Right Gun VUK coils.  I suggest the coil sleeve has been replaced previously with a sleeve that extends far enough out the top of the coil that the slight mushrooming of the coil plunger is binding on the sleeve

Fix:

  • Replaced the coil sleeve with one that extends less out the top of the coil (Part = 03-7067)
  • Trimmed (bevelled) the edge of the VUK plastic top extension (Part = Armature Assembly A-13270)
  • On assembly replaced missing coil bracket stud with bolt/lock nut

Issue STTNG-20180303: Getting Air balls off stand ups either side of Beta Quadrant Ramp

  • New backing foam into these standups, also the Time Rift standups as a precaution

Issue STTNG-20190210 Broken Plastics

  • 31-1803-10-SP Ferengi set left side
  • 31-1803-32 cracked, not so necessary to replace

Pinball: Williams WPC Boards

Power Driver Board

WPC-S and Earlier Driver Board:

    • BR1 to C6 & C7 (15,000 mfd @ 25v) to F114: +18 volts used for lamp driver columns. Then the 18 volts goes through voltage regulator Q2 (LM7812) and F115, and is converted to 12 volts (regulated) for the switch matrix.
    • BR2 to C5 (15,000 mfd @ 25v) to F113: +5 volts. The bridge and cap that fail the most.
    • BR3 to C8 (100 mfd @ 100v) to F112: +50 volts, used for solenoids.
    • BR4 to C11 (15,000 mfd @ 25v) to F111: +20 volts, used for flash lamps.
    • BR5 to C30 (15,000 mfd @ 25v) to F116: +12 volts unregulated for playfield devices, dot matrix display, and the coin door.
    • BR1 (on Fliptronics II board) to C2 (100 mfd @ 100v) to F901-F904: +50 volts used for the flippers. Located on the Fliptronics II board.

Pinball: Twilight Zone

Purchased Nov 2017

Initial observations

  • Playfield in great condition
  • Cab in good condition
  • Some GI out

Issue: TZ-20180119

Resetting sometimes when both flippers pressed

  • Replaced all Rectifiers & large capacitors

Power Driver PCB Observations

  • On removal notice GI socket (cable side) has been replaced and shows signs of heat damage
  • Q64 and upstream Q75 have had rework, but only 1 lead of Q64 is soldered to the board on the PCB underside (Q75/Q64 = Solenoid 05 Right Ramp Diverter
  • BR1 / BR2 heatsink retaining screws: 1 was very loose, the other was barely done up

Issue: TZ20180204 Some GI Strings out

  • Playfield Left WhtBrn/Brn
  • Clock + Insert WhtYel/Yel – 4 x leds on clock face are good, will have top see what ‘Insert’ is
  • Insert Main WhtGrn/Grn

Pinball Replacing gates

Piano Wire 

This is very stiff and durable steel wire. Excellent for forming replacements for ball gates, spinners, and linkages. It is bendable with pliers but will stay as formed. Stands up well to ball impact. Comes in two sizes, the thin is .047″ and the thick is .063″

  • Leftmost lane has a one way gate, is broken
    • Complete gate is A15661 usually sold out
    • 12-7045 is wireform only
