Hi,
I have for repair a LG 42PC1DA with a picture (see attached) that is "washed out" and when you change channels it is very slow to refresh, the picture does slowly fill out but the left hand side of the screen is the last to refresh.
I have checked the panel voltages and they seem ok, I have also reloaded the firmware and the fault remains.
I think I need to change the X and Y sustain boards , unless anyone has had the fault and knows different.
I apologise for the quality of the photo but it is very difficult to get a decent image of the fault.
