    The best hacks usually take longer to perform than fixing them the correct way, and many times, cost more than fixing them the correct way, too

    The idea of a field repair is to return the next time you collect with the right parts, and fix it right... now, how often that really happened...

    Quoted from jimster102:

    they soldered all the pins together game was full of this kind of stuff

    On a DE PS, CN8 is a GI connector. Output I believe.

    4 pins are supply, and 4 are return. The top 4 are tied together via trace, and the bottom 4 are tied together via trace. They often burn, and that repair you see is actually pretty typical.

    At least they left fuses in circuit instead of just jumpering across the clips!

    Quoted from barakandl:

    Nope!
    The 2n4401 transistor is installed backwards. They went as far as replacing the PIA before zip tying the relay shut.

    I found it on Facebook in about 10 minutes. The clue to me was probably that I've started at a ton of these recently, and the offset solder pad on that transistor was facing the opposite direction as the row below it.

    The Sys 3-7 driver has a few design errors that are annoying. For example, look at a modern PCB. All ICs have pin 1 facing the same direction if they are mounted North - South. And All ICs have pin 1 facing the same direction if they are mounted East-West.

    On a Sys 3-7 driver board, that is NOT the case. Pin 1 is marked on the back of the board, but when the boards are filthy (and most of the ones that come to me ARE), it's not always perfectly clear!

    Quoted from vid1900:

    There are little adhesive dots that you use for circuit board repair when you need to stick down a wire.
    And I think we have all been guilty of using a hot glue gun once in a while. Little dots of hot glue.
    But that board is just crazy.

    These are great...

    That board isn't.
