Facing TV Problems? Ask a TV Technician.
Hi and welcome,Thank you for the question and your patience. Should you still need assistance for information purposes only... Initially, have you tried another outlet? Or unplugging for an extended period of time? Or temporarily disconnecting and checking all speakers and its wires, plug back in the power cord only, set the volume to the lowest and turn on?
Ifound the prob. Broken board. Thxanyway.
