As a new user of Behringer's X32 Rack digital console at church, I was forced to switch to our old analog mixer last weekend, 45 minutes before service started. The X32 simply wouldn't boot, on the second occasion we were to use it, no less.
The problem was easy to diagnose once I had the cover off -- a resistor in the power supply unit had blown up sometime during the week (picture attached).
Firstly, I need to get my unit up and running again, and I don't know the value of the little ceramic capacitor sitting right beside the bad resistor (it burnt up too). Check out the attached photo -- it's the capacitor circled in red (C4); can anyone tell me what it's rated capacitance is? I want to fix it myself and soldering on a new component is not a problem. I don't have warranty, or patience for shipping.
What might be the reason for the meltdown? I'm not entirely sure what is the purpose of the parts that blew up, but I'm guessing it's an RC circuit for filtering or smoothing the current discharges from the very high-capacity capacitor beside it. The obvious culprit is a power surge, but I think that's unlikely because it was plugged into a surge protector, which in turn was plugged into a battery backup with surge protection. Maybe one of these things is just too old and manipulates the mains in such a way that the mixer doesn't like? This was the first time I had left the unit on all week, so maybe something in our wiring just wore the power supply out over time.
My confidence in the unit just sagged quite a bit considering this happened while it's practically brand new. Maybe this is just a fluke and the resistor was bad?
Looking into similar cases, it appears that the X32 Rack does not have a high failure rate, but most fails do stem from the power supply.
It looks like most of the time these power supplies fail because of the cheap electrolytic capacitors that are used. I've seen plenty of these accounts, but nobody with my exact problem.
