Be careful, all you have done is alter the vs, va and the 5v line, these should be adjusted exactly to what the screen requires, the fact it diminishes the mal discharge is irrelevant.Do you want the service manual.The voltages required are on a label on the screen.

Have seen somewhere,how to measure to set correct voltages,but could not remember measuring points.Boss made me adjust by sight becouse he had someone for it.its now gone but i prefer to try and do things right.So any help for a future one would be great.

Hi

LG did a Mal discharge Jig for some models, but I'm not sure if it applies to this model
