    Default 2003 Sammy Machine - Reel lighting issue

    Hey everyone. I scored another Hokuto No Ken machine in my area. 10 of the lights were out so I purchased some replacements and realized that some of the bulbs that were not lit were actually not blown.

    Problem: The left reel does not supply power to the top and bottom bulbs. The center reel does not provide power to the bottom bulbs.

    If I take any of the faulty reels and connect them to the right most reel, ALL the lights are lit up. The problem is not the lights or the board the lights are fixed to. The problem at least has to do with the power board that the reel assembly connects to. I looked it over and do not see any obvious faults with wiring or board level problems. Here are some photos:

    Circled in red are the power connectors for the bulbs. Once again, the right most side provides full power to the bulbs. I removed this board and examined it. It appears healthy.

    ^ Circled in red is where the power board for the reel bulbs connects to.

    I hope someone has ran into this in the past. Any help is appreciated! If all else fails I am going to try to jump the pads on the board that the bulbs are seated on. It will look weird during lighting animation but at least they will be lit up.
    I am looking for a Hokuto No Ken (Fist of the North Star) Pachinko/Pachislo. If you have one for sale and are in the USA please let me know!

    None of the pins have been pushed in to far and not making contact?

    No, ive tried re-seating the cables many times. Wigglig and shaking all the connectors on the machine as well. Simply moving the reel to the right most bank lights them up instantly.

    I'm going to take a multimeter to it over the weekend and verify that the connection at least makes it to the video driver (board that controls the LCD). If the problem is in there I might be in trouble.

    I would start at the light pins with a VOM to verify whether, or not power is present at them, then wok your way either up, or down the circuit(s) in question. I don't know if the board has any SMD fuses, but if it does, those might be worth taking a look at (assuming no power at the pins).
