LC II Reverse polarity capacitor

Recommended Posts

I accidentally soldered a tantalum capacitor in backwards on C21, I was try to diagnose a faulty power supply and I decided to resolder all the caps on the logic board to check that they weren’t the problem, the power supply was dying but I’m still worried i fried the board, am i okay?

any chance

Yes, there is a chance. I saw someone replace a tantalum cap backwards a few times and blow it each time - did work after they realized it was backwards.

The capacitor itself looks fine and there’s no direct shorts to ground anywhere, I’ll switch it around and see if everything is okay, I still need to get a new power supply, but does anyone know what C21 does?
