I have LG 45V model monitor.
Problem was Characters and video both vibrating and sine waves like both sides of screen. I have changed 150 uF / 400V capacitor in SMPS. Vibration problem was solved, but new problem starts that black lines/bars moving from top to bottom. If I adjust Voltage adj. port VR901, Black lines goes but Shhh... Shhh... sound starts.
