I have a Samsung LNT4069FX/XAA. The backlight and everything turns on but the screen slowing like warms up white, after about 30 minutes of it warming up i turn it off and then back on and it then shows video. I cant find any schematics for the FRC or the Main Board. I tested voltages on the Power Supply and everything checks out via the labeled voltages on the back of the board. Anyone have any ideas?
