Question about Televison & Video
It is common that when you replace the Y-sus you replace the x sus, especially when dealing with LG, LG also recommends when replacing these board to replace the Digital singnal processing board also. also make sure that before you connect power connectors to the sys boards you measure and adjust the VA and VE and VS voltages to the factory spec's voltage chart that are on the label attached to the panel. Not adjusting these voltages to the correct values could blow the boards or if to low could result in unexpected results.Not to say this is your case but, with my experience with working on LG units we always order all four major boards in the unit. I would be looking at replacing digital board or logic in this case seems you have a thermal problem on one of the boards, but since you already replace several of them and have the same results try replacing the board that is actually responsible of producing the picture on the screen , Logic board assembly. Logic and digital may be one and the same board. GOOD LUCK...
