I've heard good things about CM customer service if the product was recently purchased or still within RMA timeframe. It doesn't hurt to give them a call/email and ask.

Most likely going to be a bad switch or solder joint as that is what it typically is.

Yeah, maybe I will have to see if I can fix. I will contact them but I doubt it. It was purchased a few years ago.

I scratched off green isolation from the connections and just soldered them to original solder point and it works like new. No need for copper wire or to cut off original solder.



Thank you, you are my hero sir, the scraping of the protective plastic was the key to my working key! I tried once before to just solider it together to no avail.
