Re: My LG 32LH20 LCD. Lines through picture, now no picture.

Hi there! With regard this LG 32LH20, with the set off unplug the connector for the control panel, and turn set on using the remote control; if problem still there turn it off;
unplug the IR connector for the remote control; turn set on using the power button on TV. Also check soldering side of power supply for any signs of components legs touching
the metal frame causing erratic symptoms like the ones you're having; if so, use good insulation there to solve this problem.
