I am repairing a Samsung TV, Mod. 2028M9A, Chassis kS9A. The problem is that: the horizontal (OH), original output is T = 2001HI, is burned. I put the Transistor (T) C4458. With this T he opens (oscillates), but heats up out of the ordinary, along with the IC of the Vertical output, in addition the colors are very pale with distortion in the corners of the screen. I wonder: Is this overheating at both outputs next to the color and distortions at the corners of the screen, is it caused by the Horizontal Output Transistor? TO H )
