Disclaimer: my friend gave me them for free! I have the Behringer Truth B2031A powered-monitor. I use it to mix recordings my friends and I make in my home project studio. I don't feel that I overuse or misuse it, but apparently I am. The right monitor stops working after about 5 minutes of use. I shut off the power switch, and then turn it back on and it works again. Any suggestions of what I could be doing to cause this, or how to fix it? Thanks!
