Question about LG RH177 DVD Recorder/HDD Recorder
Problem is either the lens or the potentiometer regulating the laser beam. You can try cleaning the lens with a cleaner disk, or you can access the lens directly by disassembling the unit.Here general directions on how to clean the lens: When you get no disk error.
If that does not work, then the problem is usually the laser regulation. In this units there is no potentiometer that can be tweaked. Regulation is done through an IC. In that case repair is done replacing the whole optical drive.
