My hitachi big screen has red shadows on picture how do i fix it


What you described sounds like a convergence problem. When convergence has failed the colors will commonly look 3D,warped, etc. This tips page here on Fixya has more details.

Sometimes the picture looks caved in and the color isn't as good as it used to be also some times there is a shadow


Your symptoms sounds like a damaged or intermittent convergence IC.

There are two and very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

If your colors line up in the middle of the set and at the top but the picture is concave then you may have a faulty component in the pincushion circuit. When this circuit fails the picture will have an hourglass shape to it with black in the middle on the sides, or you will see square objects as hourglass shapes.

If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon and it should only add the cost of the part to the repair.

You will want to get this symptom fixed before there is a complete failure of the convergence circuit, which may take out other components.

I hope this information allows you to resolve this issue.

Picture shadow on rear projection Sony big screen TV


You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

Problem with my big screen


I have had the same problem with my projection tv for a long time. I finally called a tv repair man and he told me that the converter is out of alignment and that I needed a new converter. It is costing me $360.00 to repair it. Let's hope it works.
