Did I permanently damage my IO Board, or is it ok?

Unread post by Zesty »

Background:

On my IO board, I trimmed and re-flowed the leads on the LED headers to better fit the RTC spacer. During the process I accidentally removed the capacitor at C2. I soldered the capacitor back on and put the IO board back on the DE-10, but my MiSTer wouldn't power on. I removed the IO board and the DE-10 booted normally. I was hoping it was just a bad joint so I re-flowed the solder for C2 and now everything appears to be working correctly.

Question:

Is my IO Board and/or DE-10 probably fine, or am I likely to have damaged one or both of them when I tried to power them on? Are there any tests I should run?

Check that the headers aren't shorted, you have power and ground next to each other, and verify that the C2 pads aren't shorted.

I double-checked and there are no shorts. Everything appears to be functioning normally now.

Since it started working again as soon as I re-flowed the solder for the capacitor at C2, it seems like the only issue was a bad joint there.

Is there any reason to assume that the IO board or DE-10 might have been damaged when I attempted to power them up while C2 was disconnected? If not, I'll stop worrying.

(Edit: Over a month later and it's still working fine. So if any damage occurred, it wasn't a fatal blow. :lol: )
