    If the MK cart is clean and the Genesis plays other games, then the cart is most likely damaged in some way. I have an Ecco 2: The Tides of Time cart and a Game Genie which do the same thing. TMSS screen and nothing afterwords.

    Thankfully, MK is a super common game.

    No, I do not have another cart I sold them as I never realy used my genesis in the late 90s when I sold them but now I wish I didn't do that.

    Try holding the cartridge backwards/forwards when you turn the unit on to see if that makes it load. If so I'd suspect worn slot pins or a still dirty cartridge. If not, you'll need to source another game to narrow down the problem.

    You'd need a lot more heat than a stuffy upstairs room to kill a console. The cart slot is probably just really dirty. There's been tons of threads on the subject of cleaning. The easiest solution is to use rubbing/isopropyl alcohol and a toothbrush. You may want to flip the console upside down so crap falls out of the slot.

    ASIC rot will do that. Open your console and check.

    Edit: to see full res image click on the thumbnail and then click on the bigger image to see the full resolution image.
    If someone would like a close up of a part of the board just ask and I will do it.
    I really do hope I can get my system to work because when a genesis breaks there is one less in the world.

    Did you try turning the unit on with the cartridge pushed forward or backward? The goal is to rule out loose cartridge contacts.

    Check the strange solder spot to the left of the letters 'CN3'. If that isn't the problem:

    1.) Start up the system with a bare game PCB inserted.

    2.) Check the address and data pins on the ROM for voltages below one volt with a multimeter.

    3.) Report your results.

    By now after countless attemps to get it to work including re-soldering the spot by cn3 I just ended up on buying a "new" (well it was actually used) sega genesis I got a good deal on it anyways.

    Just because you got another Genesis doesn't mean you should give up on this problematic one. And I think I see something between pins 158 and 159 of the Sega 315-5660-02. It looks like the two pins are shorted together. Could you take a better shot of the chip so I can confirm if the pins really are shorted together?

    What hookup were you using? My Model 2 Genesis used to do this a lot and I thought it was dying. Later I got a Composite cable and the problem went away. Here the RF adapter was going bad and was screwing stuff up.
