Petit Crouton/Prizm Fried?

[forsytjr]

I recently got a Prizm sound card and got it all wired up. I had a tri-color rebel, hooked up as well as an accent light on a switch. No charging port (yet). Everything was working beautifully - sound and LEDs. I was still working on getting it mounted into the saber, when I accidentally put the battery in backwards (negative to positive) - a single 18650. Before I noticed the mistake, some smoke came out from around where the battery wires mount to the board. I pulled the battery out, but I can no longer get the board to do anything. I did notice that one of the accent light wires had come detached. So it's possible I shorted an accent LED pad, although it's also possible this happened as I frantically jerked out the battery. In any case, the smoke was from around the battery connection. Looking at the board under a magnifying glass, I can't see any evidence of damage, other than some burn marks on the back side of the surface mounted thing next to the spot where the battery connects to the board. That could be from soldering though. I am suspecting the surface mount device next to the battery terminals has gone bad. The numbering on the top of it is "107 16k 323". After a lot of searching I can't find out details on this device though. It looks like it is some sort of diode/power switch. Any ideas what this thing is, and how to test to see if has gone bad. The resistance across the device is only 20 ohms.

Any ideas would be greatly appreciated before I send it back to Plecter labs for repair. It was supposed to be a Christmas present.

Welcome to the Forums.

You can PM Zook, who handles repairs here in the United States. Of course there will be a charge to repair/replace the component(s), that you might have accidentally fried, plus shipping costs.

Thanks, I'll give that a shot. I tried PM'ing, and it said I didn't have permissions for that page. Perhaps that is because I just registered my account here today. Lurking for a while, but first post.

That's probably why. If I run into Zook, I'll let him know to pop into the thread.

Yeah if the voltage is reversed it will blow the main cap and possibly the audio amp. I am out of pocket for a day or two. We can work on getting it repaired after Christmas.

Zook, I still can't pm you for some reason. Let me know when you would be able to help with this.
