As a public school teacher who now suddenly has extra time on his hands, I've finally jumped in to fixing a few odds and ends on my Creature from the Black Lagoon. The two big (unrelated) issues I'm having right now:
1) The left flipper is not holding. A quick tap of the flipper button and flipper works as usual, but hold the button and flipper flips quickly and stays in the down position. Right flipper performs as usual.
Test results at startup: Check switch 64, check switch 65, F1 R Flipper EOS, F3 L Flipper EOS.
So far I have cleaned the optos on both sides and pulled and checked the fuses on the Fliptronic II board. Fuses were fine, clean optos made no difference (although they were filthy).
What should I look at next? Any way to adjust the EOS on one side? Get a new one?
2) Sadly, my Mike D mod is no longer working. My guess is overheating caused whatever is going on. The monitor is fine - I connected it to another HDMI source and it works. I tried connecting the HDMI out on the Raspberry Pi to another TV and got nothing.
Pulled the flashdrive to check what was on it (never done that before) and it appears to be unformatted. I don't have a micro SD reader, so I haven't checked what's on it yet. What what on the flashdrive originally? Did the micro SD get wiped out? Has anyone else had issues with this mod getting too hot?
There are lights on both the Raspberry Pi board and the custom Mike D board underneath it. After startup, there are lots of different lights that light up on the "fuel gauge" on the side of the Mike D board, so I'm hoping it's not cooked.
Any help troubleshooting would be greatly appreciated!
