    I have a Data East Last Action Hero with three fuses on the power board that I cannot get off the backboard. The fuse holder metal sides have snapped off on both sides, top and bottom. Since I cannot take the board off the metal backboard (I cannot get the screws off in three spots due to the location of the screws and stripping). I am having a hard time soldering the three replacement fuse holders back in place.

    Any suggestions?

    If you are looking to do a hack and get it back up try remote mounting the fuse holders. Just solder a wire to each broken fuse holder end with the other end of the wire going to a fuse holder that you mount remotely.

    In the future, when someone is willing to put in the effort to remove the board from the backbox, they can remove your hack and replace the fuse holders properly.

    And, to continue on the theme of a hack, you can use the inline fuse holders with wire ends instead of dangling an open face fuse holder. Just don't buy the cheap white plastic ones as they are not designed to carry much current and also like to break down due to heat. Just don't use the inline wire type if your fuse is a 20 amp GI fuse.

    I don't want to chance a major board issue by hacking the fuses.

    I would rather figure out a solution to affix new fuse holders to the board. The power board will not come off of the backboard. Otherwise, it's a fairly easy soldering job.

    Soldering vertically into a tight space is a challenge, especially making the solder stick. There's got to be a solution...

    You need to get those screws out and remove the board… That to me is a bigger issue than the fuse holders… If you need to drill the screws then then drill the screws… But not being able to take your boards out of the back box is a big problem...

    ^^ What he said .... when a transistor blows or a header is tarnished, you have to remove the board anyhow....

    Bite the bullet now, and get that board out so this repair job becomes easy aswell

    (when stripped, put a srewdriver behind the head and turn it loose with another giving it some pressure)

    Agree with the 'get board out' camp at all costs.

    Some things you could try:

    Vise grips on screw head, dremel cutter tool to cut slot in screw, cut around circuit board (last resort, and not a great idea), but you need to get the board out. Don't take 'no' for an answer.

    go home depot and get an "easy out" set. bring pics with you. you will have to take the door off to use the "easy out" and a drill. g.l. joe

    Remove the board. Do not attempt to work on this mounted in the backbox.

    I like the easy out set idea. The darn screws that Data East used were shallow and narrow. They also screwed the damn things down very tight too. I will persist with the board removal. Thanks!

    Full forward on the board gently while unscrewing each screw.

    DE fuse clips were of very poor quality.
    It takes a lot of heat to remove them from the board.

    Really does make you wonder - who made those fuse clips?

    Bumping this thread to probe for more info here. What is the secret? I always have trouble with DE fuse clips. The solder side comes nicely but I often pull the vias and traces on the component side. The clips are "hooked" into the solder side of the board and they are too short to straighten. I apply plenty of heat and always add solder.

    arolden the best you can do is to use sharp side cutters to clip as much of the fuse clip off on the solder side as you can.

    You will pull some trace material. There is no way to avoid it.
