TL;DR

Stern Tech School tutorial on using Diagnostics lamp tests for pinball maintenance.

Summary

Stern Pinball educational content demonstrating how to access and use the Diagnostics menu lamp tests for troubleshooting and maintenance. Kyle covers four lamp test types: single LED test (individual lamp/RGB control), all LED test (illuminates all lamps), GI test (general illumination circuits), and flasher test (bright effect lamps). The video emphasizes using service switches and manual lamp charts for systematic diagnostics.

Key Claims

Service switches are required to access the Diagnostics menu and lamp tests
high confidence · Kyle demonstrates accessing diagnostic menu via service switches and coin door interlock
Pinball machines have addressable lamps controlled via node boards with specific connector assignments
high confidence · Explanation of single LED test showing lamp numbering (228, 229, 230, etc.) mapped to node board connectors
General illumination (GI) circuits typically control three or more bulbs wired in unison
high confidence · GI test description: 'Most general illumination circuits will have three or more bulbs attached to one circuit, and they will flash in unison'
Flasher LEDs are addressed separately and do not appear in the all lamp test
high confidence · Kyle states: 'As a note, flashers will not appear in the all lamp test. They are addressed separately. They must be called up in the flasher test.'
Feature lamps are controlled lamps that indicate shooting targets or game status; GI lamps light underneath plastics and are generally always on
high confidence · Kyle distinguishes: 'feature lamps, which are things under the playfield or are controlled to tell you where to shoot' vs 'general illumination, which are the lights that light underneath plastics and are generally always on'

Notable Quotes

“Using the single LED test, we can have the pinball game light any addressable lamp on the playfield, as well as individual RGB—red, green, or blue—LEDs.”
Kyle, Stern Pinball @ ~2:00 — Core explanation of single LED test capability for granular diagnostic control
“In your manual, there is a chart of lamps. These are all of the addressable lamps that your pinball game controls.”
Kyle, Stern Pinball @ ~2:45 — Directs users to manual documentation for lamp identification and troubleshooting reference
“Flashers will not appear in the all lamp test. They are addressed separately. They must be called up in the flasher test.”
Kyle, Stern Pinball @ ~8:15 — Critical technical distinction that clarifies why flashers require separate test selection

hi I'm Kyle with Stern Pinball and in this video we're going to go over the different lamp tests you can go through in the Diagnostics menu on your pinball game to access the lamp test we'll need to use our service switches so we'll start by opening the coin door and next pull the interlock switch out to the service position to restore power to the Playfield using the service switches we'll enter the diagnostic menu selecting it with the black button from here we can scroll over to the lamp menu we're presented with a few different lamp tests here single LED test all LED test GI or general illumination test and flasher test let's start with the single LED test using the single LED test we can have the pinball game light any addressable lamp on the Playfield as well as individual RGB red green or blue LEDs to select which lamp we want to test we can use the red buttons on the service switches to scroll through lamps shown on the LCD screen in your manual there is a chart of lamps these are all of the addressable lamps that your pinball game controls for example lamp 228 is our mystery light on this billboard here the rest of this information pertains to which node board board drives it which connector it comes from hitting the red button plus one time will switch to lamp 229 which will change to the scream lamp on the billboard here the next lamp 230 231

Etc the next test in the lamp test menu is the test all LED test selecting this test will illuminate all controlled lamps on your pinball game the next test is our GI test or general illumination test in a pinball game you'll have two different kinds of lamps the feature lamps which are things under the Playfield or are controlled to tell you where to shoot or telling you something is going on and general illumination which are the lights that light underneath Plastics and are generally always on in this test the game will pulse each different General illumination circuit most General illumination circuits will have three or more bulbs attached to one circuit and they will Flash in unison on the screen we'll get some information about which connector on the Node board they are driven off of uh some wire colors and their number which will also correlate to the lamp chart in your manual the final lamp test we have is the Flasher test the Flasher LEDs are the ones that are bright and come in light shows to show you you've done something good to select the Flasher test highlight lighted on the LCD and use the black button to enter the test in this test we can scroll through each lamp that is considered a flash lamp as a note flashers will not appear in the all lamp test uh they are addressed separately uh they must be called up in the Flasher test this was another video from Stern tech school
