Hello all. I recently purchased the Studio 50USB studio monitors from a seller on Reverb. The package is an unopened package and the speakers were brand new warranty replacements. Initially, when I turned the speakers on, there was a repetetive clicking and the speaker turned on and off with the clicking every second or so. With some work with the power cable, I was able to get the speakers to stay on, however, now there is no sound coming from them at all. I was using the quarter inch input ports as well as the usb ports directly from my computer. Anybody have an idea of what the problem could be? TL;DR - Speakers are new but no sound comes out when powered on.
