You have a convergence problem. Most likely the convergence IC's will need to be replaced.

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.

Hourglass Shape


If there is a hour glass shape to the image but convergence is normal, there are 2 possibilities. You either have a pincushion correction problem or if the hour glass seems to be moving, it will be an open filter capacitor in the power supply.

Unless you are electronically inclined troubleshooting this issue will require a factory trained service technician. You can expect to spend $300-$400 to fix this.

Hourglass Shape


Yes check for fluid leakage and see if the crt's are leaking fluid down on board. if so you have to change some caps any that got wet. If not wet at all then something that was fix maybe has a solder bridge on it look carefully and see if anything out of place
