Buying caps can take hours when you have to go through datasheets to make sure the size is right, so I think that's a pretty fair price.

If I can save a couple dollars doing something that'll take me hours, I will.
Anyway $5 isn't bad either, I just thought it said $15 for some reason.

Anyway, that's not a capacitor, it's an inductor. Pretty sure that's epoxy, as Rolf suggested, so it's fine.

I'm all for supporting the scene and all, but his kit's pretty expensive.
Mixing your own set of caps is way cheaper if you just look around.
Tayda Electronics is especially great, if you're fine with 1-2 week shipping time.

EDIT: I do not know in my wildest dreams why I read $15, but hey.

Also the pot itself doesn't make a crackly noise but the speaker does when you move the pot to adjust the volume.
@alley beach: yah it's kind of a miracle in itself that most of the gameboys left still work almost perfectly or do after a little tlc.
@apeshit: Yes that sounds great! If I can't figure it out today ill pm you the details about shipping it to you. Thank you so much for being patient and helping me with this issue.

That's just glue. It's always looked like that. Can't say I know what the problem is with the sound because I don't have the unit in front of me, but usually the problem is the soldering job. The more recent set of pictures doesn't look that bad though, so it's hard to say.

If you're getting a crunching sound out of the pot when you move it, it's dirty inside.

Never heard back from you about this - did the one I installed for you work properly with your gear?

PM sent.

If you can't figure it out, one of us can take a look at it and get it up and running for you, if you're keen on shipping the motherboard to us.

Got my inbox worked out, turns out it was just full. So feel free to PM me if you prefer. smile

The prosound isn't going to give full volume.  You have to have it ran to a powered audio source.  Static during volume adjustment can be caused by a damaged or loose volume pot caused by too much heat during soldering but it doesn't look like you soldered to the pot so that shouldn't be the problem.

Well even through a powered audio source the prosound doesn't work or makes whining noises.

I was starting to think my PM box was broken as I haven't received any PMs in months. I guess this confirms it.

Does your new board have the clock mod? If that leaking component was from the mod, it would've been from that and not the pro sound.

Is there any shorts at the solder points? It's hard to tell because it seems to be glued.

Yah my board does have a clock mod and I don't think the prosound directly caused the power board problem. But now that the new powerboard seems to be working fine the only problem left is with the audio.Here are some pictures of the solder points (without glue) by the pot if that helps:

Well the first time I installed the PCB the component did that but now on the new board that component doesn't seem to get hot or cause any problems. I do get sound out of the normal jack but when you try to adjust the volume it starts making static noises and you do start losing noise out of different sides. Also the prosound jack just gives me partial amounts of sound or none at all.

The prosound isn't going to give full volume.  You have to have it ran to a powered audio source.  Static during volume adjustment can be caused by a damaged or loose volume pot caused by too much heat during soldering but it doesn't look like you soldered to the pot so that shouldn't be the problem.
