I've been trying to fix my STTNG for a couple of days now with no success, any help will be appreciated!
While playing (all was 100% functional), I started to get issues with balls not detected. At the same time I smelt what you never like to smell playing with an electronic device... Switched the STTNG off and opened it, F103 was blown and Solenoid 37 was burnt and locked, I replaced F103, S37 and the sleeve.
I restarded it and tried to test stuff, but realized F103 was blown again, I replaced it and started the STTNG again but playfield opened. As soon as powered up again S37 locked itself so I switched the pinball off immediatly to avoid further dammage. Then I looked here and over the web to check what else needed to be tested.
I found out that Driver and Pre-Driver needed to be verified, and saw that Q16 didn't show up good values on the tester, so I replaced it. The pre-driver in Q8 was showing good values. At the same time, while in there, I made the famous additional tie-back from J108-1 to J4-1 (the original one was still in place).
Now when I start the game, I'm till getting this S37 locked and I don't know what to check next!
Thanks in advance!
