I have a vocopro karaoke stereo system with amplifier all in one. It a machine where I can hook speakers, dvd player, and cd player up to it. And it has input where I can put in microphones for Karaoke. But I'm having audio problem with it. Video is okay, but the audio stops / cut off after it's been turned on for 10-12 minutes. And then when I press the power button to turn it off and then on again, it would work for 10-12 minutes again and then the audio would stop. Please help me with this problem. I tried unplugging it and resetting it, and reconnecting all the cords, but it didn't work. Thank you.
