My Mortal Kombat 2 cabinet is working great except after about ten minutes the audio goes out completely. If I leave the cabinet off for a bit it seems to fix itself, but then after about ten minutes the audio goes out again. Sometimes when I turn on the cabinet the audio will sound muted for a bit before going out. I've also heard strange, high pitched noises, coming from the speakers kinda like feedback or something. I'm assuming either I need new speakers or there's something wrong with the power supply but not totally sure. Any insight to this issue would be greatly appreciated.
