Question about LG DU-42PX12XC 42 in. Plasma HDTV
How do I adjust the Y-sus board?
SOURCE: missing voltage?
alot of voltage adjustments at that high voltage are likely from another source that develops it like the the swith-mode power supply upstream on power supply board that feeds it ..look for burnt resistors in this case.. I bet your in the wrong circuit but u can test all wires and pins coming in for 200 volts. get a schamatic of it and find a good tech if u dont know what i am saying. ty crazylarry

The majority of the time it is the Y Sustain module. I, myself being in the service industry, I always replace the Y drive boards also. The Y main is the large board on the left and connected to that is the y drive boards or board, depending on the model. Check for pico fuses open on the Y and that's a give-a-way.
