16x24 LED Matrix

[quote][/quote]I recently purchased a 16x24 LED Matrix and it does not seem to work. I wired it up, soldered the J5 connection, and uploaded the libraries. However, when I try one of the demo's or even some of my own code the LED lights may only blink for a fraction of second. I am noticing that I, unlike a few other posts, do not have a capacitor connected to C1/C2.

Post a photo showing your hardware and connections and we'll take a look. 800x600 images usually work best.

Here are the connections. Could it possibly be that I am missing a capacitor of some sort in the C1 C2 slot?

That doesn't look like one of our LED matrices, and it doesn't seem to use the same IC as the ones we carry.

I can se that it's a Holtek device, but can't see the exact part number. Your best bet will be to get the part number and look for a datasheet. That should have a good description of the control signals and protocol.
