To Twin Fami Turbo owners

[2A03]

I'm in the midst of checking up on my Twin Fami Turbo and I noticed some of the capacitors on the motherboard have leaked, some worse than others. If you have a Twin Fami Turbo I'd suggest checking out the caps and get them replaced ASAP.

EDIT: Just replaced all the caps on my Twin's motherboard, it seems that almost all of them leaked in some way. I'd really like to see if mine was an isolated incident or if this is a widespread issue much like the Game Gear and TurboDuo.

Did not know Turboduos had that problem too. I'll check my Turbo Twin Fami and see.

Twin Fami Turbo? You mean the Twin Famicom with rapid fire on the pads...?

Yes.

Yeah, it's by far the most common problem with those consoles. It's the same thing as the Game Gear and TurboExpress, they were plagued by poorly made surface-mount caps that would fail prematurely and cause potential damage to nearby traces. I didn't notice any damage caused by the leaky caps on my Twin Fami though but it's better to be safe than sorry.

I haven't seen this problem. Could it be noticed on functionality?

Tend to see a fair amount of twin famis with no sound or broken video output, guessing this (leaky caps) is the most likely culprit.

After replacing the caps, my Twin Fami seems to be making this odd ticking noise in the audio. I'll see if I can get a recording of it later and hopefully someone can pinpoint what it might be.

So it worked fine before you replaced them?

[2A03]

Actually I think it started doing this before I replaced the caps, I'm not too sure. Here's a recording: http://www.mediafire.com/?7702umd4g20lz5x

No one has any ideas?

Wrong polarity on a cap, maybe?

If that were the case, I'd have a blown or leaky cap on my hands. I'll have to double check later but I'm very sure I put in all the new caps correctly.

Is it just the turbo?  My regular black twin famicom has quite perfect looking caps.

It seems to be, but I'd still like to know if mine was just an isolated case or if this is becoming a problem for the Turbos. I noticed that my Turbo was manufactured in 1989, so I'm curious if the Titler may have the same issue or not.

I've never had a console or arcade pcb with caps that died.  I read about the batteries on arcade pcbs eventually leaking and causing damage so I removed and / or relocated batteries off of my arcade pcbs.  But I've never heard about caps going crazy.
