Jaguar went poof (literally)

[Gamereviewgod]

Moved my Jaguar to a different set-up today. When I plugged it in to test, it sizzled and popped while smoking... and I realized I had the wrong AC adapter. Super stupid mistake that I'm clearly about to pay for in some way. I'm going to be under the hopeful assumption that I could replace the AC port easily and get it back up and running? Maybe? There are no scorch marks. Inside of the board looks great. Everything looks fine.

If that's the case, where do I look for a part like that?

VOLTAGE REG is gone i am not sure as i dont own one anymore i would have helped i am sure a atari jaguar owner could help you.

Thanks for the link. Two questions: One, where is this on the board? I see a handful of chips that look exactly alike. And second, wouldn't it look scorched or show some type of damage considering what happened?

Thanks!

You'd have to crack it open to know where it is (unless someone has a convenient graphic) and it'd likely be near the power plug.

Perhaps it will be scorched, perhaps it won't be. There are no rules for what a blown chip looks like. Replacing this isn't for anyone but advanced soldering types and if you're having trouble locating it I'd strongly urge you to find someone to do it for you. I'd offer but I don't want this to look like a conflict of interest.

Yeah, this is probably beyond my basic capacitor fix soldering skills. I replaced the power jack just for the hell of it and it won't turn on at all. Whatever happened to it has killed it in its current form.

Don't know what the conflict of interest would be, but I'm more than willing to send this out. Gotta assume it's cheaper to repair than the current $80-$100 price they're going for on eBay.

I wouldn't say replacing a SOIC package is advanced types only.....more like intermediate. :p

If you have some good small side cutters and some rework flux, it shouldn't take much longer
to replace than a DIP chip.


Snip the pins at the chip body
Remove the pins from the pads with an iron
Clean the pads with wick
Tack the new chip down at the corners
Cover the pads and pins with rework flux
Drag a tinned hoof tip over the pins or solder point to point with a conical
Remove any bridges with more flux and wick

If you have a hot air station you can zip past the first two steps

Hmm. That's actually not too bad, but it's a small space and I don't have the necessary tips. My soldering supplies are basic.

SOIC is a fairly wide pitch, with enough flux you can probably solder it with almost any tip....just some might be easier than others.
I usually use my general purpose 2mm chisel for SOIC and it works fine.
