?

Ok, I know Prodigy, as a line, is dead anyway, but I would like to get my modest home system back to running condition while I shop for something more current.

So, my PMC3 was running great for a few years. I unplugged it to reorganize a few things. Ever since, it appears to power on, but is almost always unresponsive. The caveat to that statement is a few times it actually worked normally, though not for more than day or two max, after replacing the original power adapter which I suspected was faulty.

Now, the power LED lights up, and that appears to be all. Plugging into the computer port does nothing. My computer doesn't recognize that I've plugged anything in.

I'm aware this is a long shot, but has anyone rescued a unit like this, or maybe any Crestron control processor, from a similar state?
