The board says "indigo canada 600130 Rev.0"

I believe they're 1µF 100v capacitors.
This is a very good excuse to upgrade your subwoofer. Can your budget handle the price of an upgrade?
You're welcome to "TRY" and desolder, with the "INTENT" of replacing the resistors. That is if you're able to figure out the fried color code. And even then, after all the repair effort, you may find you made things "A WHOLE LOT WORSE."
(I suck at desoldering)
It all depends on if you're feeling "Dirty Harry" lucky or Saturday night lucky.
Well?........Are you feeling lucky?
And if not, use this as an excuse to add a Rythmik, LV12R (or better) to your credit card.
(fyi, that's how we ended up with a 60" flat screen. The Olympics were going start on Sunday and Saturday morning, when the wife turned the television on, oh darn, the television took a dump.)
The color rings on the resistors that give resistor value. Granted, the black when the resistor blew, ruined the value rings, which will make it difficult to read the code to replace the with the correct value resistor. Maybe the removed resistor will wipe clean. And yes, I'm not an electronic type so it's a fair assessment to say, I suck at electronics.
Magnifying the image, in the blackened shadows, I see it's not a resistor. I can't tell what part is fried. Either which way, to whom ever tries to repair the board.......good-luck with that. One can always choose to replace the amplifier.
Bless those willing to desolder a board so they can replace a blown thermal resistor and sainthood status for those who succeed.
Now, about those fried little critters directly below the resistors. As to desoldering and replacing anything, I'm going stick with ordering up a replacement Amp as that's my skill level.
Jsnrkd. What about the other components? C413, C414! What happend with them?
landed on this thread because I have the same problem too, after also 7 years of good usage.
In my case, this is the transforming coil which is burned out; the big yellow stuff having a sticker reading HI-POT OK [not it's not :)]. It is burned out on the low voltage part, namely on the opposite side of the plug. That may not be obvious at first, but if you look carefully yoy may seen some melted parts and the glue color is brownish instead of yellowish. There is also a small vertical plate supporting various resistors and a transistor that seems to have suffered from the coil's heat. Dunno if it is dead.
If someone know where to find that coil, a little post here would be helpful.
but just fixed mine for 10$. The transformer had nothing, was just melted from outside but was still functioning. One mosfet was shorted.
Got some help from there too:
As you can see, the pb is not the electronic parts failing but some bloody well designed yellow glue becoming conductive after a few years (that's called planned obsolescence indeed).
Remove the glue, change the burnt parts, no reason to fail for a long time....
