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:

- UNPLUG THE TV BEFORE YOU START.
- SOME PARTS CAN STORE A CHARGE THAT CAN SHOCK OR KILL YOU EVEN AFTER THE SET HAS BEEN OFF FOR A WHILE.
- 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!

I have a Panasonic CT-32D31 TV and I've been noticing some shrinking and curvature of the picture from both the right and left sides. Is this something that can be fixed quickly, easily and most...


Your symptom sounds like a damaged 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.

I would recommend that you have a local service center diagnose the set for you and give you an estimate of the repair.
I have seen this type of repair run from $150.00 - $200.00.

The cost of the repair or replacement of the set is completely up to you. I would most likely recommend that a replacement may be in order, as most television sets are becoming cheaper all the time.

I hope this information allows you to resolve this issue.

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?

Thanks,
Dan

This is a problem with the pincushion and convergence circuits. Are you planning on repairing this yourself? If so, I'll look up the circuit designations and parts. If not, expect a parts cost in the $15 range plus the local labor rate.

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.

you have defective horizontal linearity! replace the capacitor at the hot side mostly 160uf 180V or 160uf 160V.
