    Genesis Sega Genesis 3 clone not working

    Hello guys!, can you help me to get this console working?, is a sega clone (i suppose) with a tectoy 580g chip inside.

    When i plug the power supply nothing happen, no power, no led, no tv image, nothing.

    I took various pictures of the motherboard parts, so you can check it out.

    Thanks in advance!

    Could be a faulty power connector or the solder joints for the power connector have become bad over time. You could try desoldering the power connector then reattach it with new solder or simply replace the power connector altogether.

    I don't know if I've ever seen a Genesis 3 clone before, that's pretty cool.

    Oooh, I like the sight of that TecToy-580G. Terrific GOAC.

    As for your problem, it could be caused by one of these:

    -Bad barrel plug on the DC input (or broken solder on said plug)
    -Bad power switch (not all that common)
    -Blown voltage regulator (if there even is one, I can't tell from your pictures but judging by what appears to be a heatsink on the power board, it's possible there's a 7805 under that)
    -A short between 5V and Ground (the previously-mentioned heatsink would get very hot very fast if that's the case)

    Thank you Ace for the advice!, iŽm not so good with the multimeter or the soldering iron, but iŽll make an effort to fix the console.

    Any more tips are welcome!

    Cheers!
