I have a Big Screen Hitachi (Ultrascan HD) model number: 43FDX01B. The TV is only about 5 years old. The problem is the picture on one side of the screen there is a rainbow of colors (red, yellow, and black) the other side of the TV is fine and shows a real good picture. Can you tell me what is wrong woth it and if it can be fixed? Thank You.
It sounds like you have bad convergence IC's my friend. These are two large convergence amp IC's that are soldered on to the convergence printed circuit board. If you have the ability to solder and unsolder, and know how to work on printed circuit board, and also know how the circuit works, you should be able to repair this TV set. But you will need to know the safety facts and have the proper documentaion as well as the proper tools. If you do not, play it safe and call out a trained tech to assist you in this repair. Good Luck, and let us know how this repair turns out.
