Hi
the plasma tv brand and model are: LG 42PX3RV
the problem with this tv is that there is sound but no image at all, but after removing the cover and taking measurement for the y-sus board and found not the model to be faulty i managed the change the Vy and Vsc voltage values i noticed that the panel start to produce image but really cannot adjust the picture in order to be fine, i followed the instructions about voltage adjustement on pdp but finlly i think there still a problem either in the pdp or the Y-sus board has some bad components that prevent the picture from being good,,

i'm not sure about the source of the problem so please don't hesitate to help 

Y-sus board model 42v7
