    Hey guys, just as the title states.

    Have a Sega CDX here with no-power issues. Upon opening the console, it appears that someone else was in here before me, and I instantly found a blown sot-23 on the power PCB.

    Can anyone help me identify what this little guy is so I can order a replacement? The only pictures I can find on google are fuzzy, but it appears to have the code w7 on some of them, which points to a zener diode. Can anyone confirm?

    It's a w7 package which seems to lookup as a 3.6v zener diode.

    I'm probably going to reverse engineer the board once I get a working one from a friend.

    I'll post what I figure out.
