I am trying to fix the built in speakers on a Seanix monitor. It worked fine a few months ago, but has stopped for some reason. When headphones are plugged in there is sound, just not from the monitor speakers. We tried plugging in a different monitor (same model) and the sound didn't work with that either.
I don't know if any of this information will help, so I'm posting everything I know.
