This is called "pincushion distortion" and there is correction circuitry in the set to take care of it. Obviously it isn't working. Sometimes this is due to parts failure, but it often happens because of bad solder connections to some of the parts. I don't have a service manual for this model so I can't give specific part numbers or locations. But if you have patience and some electronic soldering skills you can try repairing it. Flip up the circuit board so you can see the bottom (the solder side) and start in the area where a connector plugs onto the board that goes to the coil of wire on the neck of the picture tube (the "deflection yoke" it's called). Work around that area and look for solder connections that are visibly cracked or very grainy looking. Good solder joints look smooth and shiny. The bad connections (if that's the cause) will probably be found to transistors, 3-leg parts that may be mounted on metal heat sinks. In fact, make anything in the area mounted on a heat sink the first parts to check. Because the get hot, they are the first ones to develop bad connections. Heat up and resolder any connections that look doubtful. A strong light and a magnifying glass may help.

Some warnings:

- With the back off the set, some TV's are unstable. Be careful of the set tipping. You may want to lay it face down on a padded surface before you start working.

Solder connections that go bad are a major cause of problems in TV's, so this might get you going. Just work carefully. If it doesn't take care of the trouble, the problem is part failure and that would require test equipment and the service manual to locate.

Good luck!

That's good you have time and patience.
You should have service manual and electronics knowledge to recognize and test / check parts in tv.
Problem is in Pin Out area of tv and you can have new parts from Panasonic Parts.
You can buy service manual from Service Manual net
Good Luck.

Sst4324 hourglass picture.

Problem could be either input filter in main power supply (picture will have a wave moving top to bottom) or in the Pincushion circuit---on rare occasions it can also be the deflection Yoke which is the large assembly on the neck of the picture tube.

Picture has hourglass look and has split screen picture hourglass comes and goes but split screen is continual

If hour glass on conventional set it is either pincussion circuit or power supply---by split screen if you mean folded over top to bottom in the middle that is in the same areas.

Picture is squished in from the sides. Sides are curved inward like a fat hourglass. Vertical setting seems okay. Is there a horizontal adjustment somewhere? or is the issue more complex

Unfortunately from your description this a complex issue and cannot be adjusted out. The cause is a shorted winding in the horizontal section of the yoke, or the high voltage capacitor has decreased in value causing the hourglass effect, depending on the problem will dicktate cost to repair, I suggest an estimate before a decision is made, and if the set is more than five to ten years old consideration should be given in a replacement.

Have you ever had this problem?

Sorry Ginko, but a convergence problem would have the curves down from the top and up from the bottom. The hourglass shape is a pincushion problem. This can be as simple as a bad capacitor in the pincushion circuit.

Could you please confirm the model number so I can look up the probable part?

Vertical hold

If the picture is in an hourglass shape this has nothing to do with vertical hold. Besides, on all these sets, the hold and parameters are all uPC controled through a firmware routine that is burned in to an EPROM.

It is obvious that there is a failed component somewhere because of the hour glass shape. The area of failure is most likely in the pin amp section. If the hourglass is from the sides, it would be horizontal pin. If it is top and bottom, the fault is in the vertical pin section.

A common cause is from a capacitor that has failed in the mentioned area. Sometimes it can be an IC or other type of component in the pin amp area, but not as often as failed capacitors.

You can take the set in to service the fault. I don't think you can fix this yourself unless you are trained in TV service and have the experience and setup to troubleshoot for the bad parts, and do this type of service.

Hourglass Picture

Pulling in from the sides usually results from poor regulation or width problems related to the horizontal circiut. These are not usually repaireable by a non technician.
