[QUOTE="Terryl, post: 1083044, member: 369937"] There may be a third PCB at fault, some HDTV's have what is called a ""T-Con"" board, this board control's the picture timing for control and logic signals for intensity and colors to the LCD screen, this board may be located at the middle bottom of the unit and under a shielded cover. If this board goes bad, so will the picture, it can be replaced if you have the skills to open the set. But be sure to get the right one for your model. Also, how old is this set? If more then 4 or 5 years then there may be a cap problem in the power supply, some electrolytic caps that are used in the power supply can dry out and bulge up over time, these caps then loose their function to filter out AC ripple and other noise in the power supply, this can affect the over all picture.
