Hi, I have a Mitsubishi 1080 Medallion model number WS-65819. I had it connected to my ps3 and was playing music on it with the internal speakers, and it was quite loud, and all of the sudden the sound just cut off. ive checked the SAP and speaker on/off settings, and it isnt on mute. I also checked all of the fuses and theyre fine too, so im stuck with no sound and no idea what to do next. help me out please??
