Audio FX Sound Board 2MB Flash not working

by LoGandi on Thu Aug 06, 2020 5:50 pm

My sound board isn't working now for making a custom horn with remote. It gets power and the green light turns on but none of the triggers are working and my computer isn't reading that it is plugged in. Tried different cables, ports and PCs.

It won't play sound when USB is connected. I don't know if that is when you're seeing the issue.

Not showing up as a USB device is more concerning.

I would start by redoing the header soldering as some of the joints look suspect. It's always good to start off with good soldering. I find that's often the culprit if there is odd (mis)behavior.

Most of the solder joints look ok, but some look iffy. Still, unless there's a short somewhere, it shouldn't impact the USB functionallity.

There's something suspicious in that cluster of components above the bottom right Gnd pin.

Check that out. It a small light colored fleck. I can't tell what it is, but if it's a solder splash it could be a problem. It light just be a reflection from some flux or board coating.

Question: What happens if you ground a trigger pin directly? Red LED? Sound?

Nothing happens. Only the green turns on.

OK, the glint on the board seems to be nothing. Many of your solder joints need redoing. Several at "blobby" and may not be making a good connection.
