The systems arrived and the MCD was the first to be checked. Plugged my MDII into it, power and RF into the MD (via some universal switchable power supply as the original one's missing), power into the MCD (via my old MD1's power supply), turned the MD on and... nothing. If emulators are anything to go by, the MCD's BIOS should've come up, asking for a CD, right? This MCDII's just giving me a black screen, and sometimes the TV's outputting a low humming noise through the speakers. Carefully cleaning the MD-MCD connectors on both machines didn't help. Then, despite not having much of a clue on electronic, I carefully opened the MCD up, hoping for some kind of obvious problem with it, like a loose plug or whatever.
Here's the insides of the MCD, plus close-up's on some suspicious things:
What's with this small brown board wired to the main one (2nd picture)? Is that some kind of fix for a factory-side problem applied after manufacturing the main board or something, is that a mod of some kind? Also, there's the empty plug socket on the 3rd picture - it was like that when I opened the machine up, and there's no loose plug that would fit it either as far as I can see.
After screwing the MCD back together, I tried the 32X. Well, I'm missing the MD-to-32X AV cable, though. But even then, the 32X's "pass-through function" - so that, when a normal MD cart is plugged in, it just lets the MD boot that, I mean - should work, right? It doesn't. Okay, plugged the 32X into my MD1, its RF cable and power supply into it, the universal power supply into the 32X, and then Space Harrier 32X into the, well, 32X. YET again, nothing. Out goes Space Harrier, in goes Sonic 2 - plain old MD game, obviously. Nothing either...
I assume that neither extension is actually turning on... I could see the 32X having this problem, because of that universal power supply - which, omg you're gonna kill me for that, is set to 12V instead of the 10V the systems need because it doesn't support 10 -, but not the MCD, which is using my MD1's official one.
Well, hope someone might've read all this crap and has some kinda idea on what I could do now - besides trashing the MCD and 32X or putting them on eBay as "untested" or something.
(and I'm not sure if there's a better subforum to put this, please move it if there is)
