Distorted soubnd on LG Smart TV 42LW5500-ZE
Good morning
I own a LG 42LW5500-ZE Smart TV about ten years old. It worked OK until about two weeks ago, when the sound quality started to degrade and has worsened from day to day. It sounds as a mix of saturation, crossover distortion, box resonation and loudspeaker cone broken. I will open the set this weekend, but before I would like to know if anybody has any experience with this. The sound make me remember class AB discrete amplifiers, when the bias was not properly adjusted and the transition of one leg to the other was not smooth, but the TV amplifier looks a class D one (NTP-7400L). TIA -- Saludos Miguel Giménez |
