So here’s an interesting little “to do”.
When I bought my Big Guns late November 2017, the guy I bought it from had the “Invinceable” light pulled out. He said “the bulb never shuts off and the heat melted the plastic so I just removed it. It doesn’t effect play.” He’s right, it never shut off, but also didn’t effect the play. The melted underside of the invincible logo wasn’t bad enough to really do major damage. Still, I want the game to be “perfect” or at least have all the intended functionality. So I did some poking around in the machine and looked up a few things in the manual. I had it narrowed down to the left underside playfield relay and/or the Q14 transistor on the CPU board.
So tonight, I pulled the board and tested the bank of transistors. Turns out the Q14 was bad. I re-flowed all the connector joints and a few others that looked questionable since I had the board out. I’m going to stop at my local electronics store tomorrow to see if they have the transistor. As a backup, I see Marco sells them for $1.69. It’s the dang shipping that always kills me.
Can someone validate the function of the flasher when working correctly? I believe I’ve seen a video before that this bulb only flashes once you’ve started multiball and loaded the designated cannon which results in the audio “Your are incinceable. Save the Queen!” And I believe the flasher will run faster and faster until the timer runs out and the audio of the scream “She’s mine now!” sounds... or you actually save the Queen. Can someone verify I have this right?
I’ll post an update if this transistor replacement completely restores the bulb function.
