This TV came to me when it turned on normally, but the audio gradually dropped until it disappeared. When I pressed the mute button repeatedly the audio came back on and 5 to 10 minutes later it disappeared again. | In my case it was the external power supply with low capacitance capacitors. Either you change the external power supply or repair it yourself. Good luck! | (D.S.E.Eletronica) | |
