This LCD set is a new venture after many years of CRT and video repair. This set has what seems like a back light problem in that the top 1/3 of the display is normal brightness but the lower 2/3 is very dark. Using a colour bar input the colours on the lower 2/3 are much darker with yellow being almost brown. This morning the power supply quit but fortunately a spare unit had been supplied, but no change to the original fault when fitted. Strangely, after I received the set and confirmed the fault, it disappeared and the set worked OK for about 2 weeks, then the fault returned. Have tried various adjustments and factory resets but got nowhere. Any help would be appreciated. Derek
