**My friend Maleko came over and set my machine straight. Seems like it was a short in a bad #44 bulb loc. 151 causing all the issues. Installed fresh bulbs and so far so good! the flasher bulbs also went bad at the same time by chance. Node board is still ok. Thanks Maleko !**

Hey guys, hoping someone can help me out here. I play this machine about 3-4 hours per day and really need it to get back on track for my sanity.

The machine is IMDN pro. I was trying to eliminate some GI flickering on the bottom half of the machine and I notice when I applied pressure to the flickering #44 bulb, the flickering went away so I assumed it wasn't seated properly. I continued to push (and twist) the bulb to re-seat it and probably. I heard a light electrical "pop". Everything was working fine and the GI flicker went away (GI light #151 on Figure 3.4.1. playfield light location per ref map in the manual). After about 30 min of play, the field went dead mid game, the playfield lights started going crazy and the slings started acting possessed
and slinging air non stop! I restarted the machine and everything was working 100% fine for hours of play. As of now, the machine plays fine for some time then finally dies/goes dark mid game for a second or two then comes back to life without issue. This does not happen frequently, only after extended play.

-After about an 1/2 hour or so of play, the #151 GI lights on both sides of the playfield begin flickering and eventually go out over the next few min. gameplay is 100% fine during that time. The same GI lights stay off for anywhere from 15 min to 30 min until the entire game goes dead for a split second (just long enough to drain) then comes back to life. (the time delay makes me think there is some sort of overheating under the playfield?)
-Every time the machine exhibits the "let's play dead for a second" behavior it is triggered by a flipper press.
-When I opened the underside of the playfield to examine the damage, I noticed a bit of a burnt smell and the left flipper coil was burning hot. This coil is located directly above the GI bulb that "popped" referenced earlier.
-The machine is located in an air conditioned environment.
-There are no fault codes/technician warnings in the diagnostic menu of the machine.

Anyone else experience anything like this? Is it safe to keep playing? If it sounds like a basic overheating issue, is it as easy as installing a cabinet fan or do we need surgery? Let me know what you guys think. Thanks!!!

Did you pull the bulb out to see if the contacts are broke? I've had several sterns from the factory with broken contacts on the LED bulbs. Caused the same flickering as your describing.

The 151 LEDs and the left flipper are both controlled by the node 8 board--as is a bunch of other stuff mostly on the lower playfield. Node 8 controls both lower flippers and both slings. A lot of stuff might behave unexpectedly if that board had an 'event'. The boards are black so it is harder to see burned parts but I would look there for evidence of the source of the burning smell.

Node 8 board is under the playfield next to the left flipper. It is a long-ish rectangular board with a bunch of connectors. You can't miss it.
