Re: tv screen has slight hourglass shape

A common fault are some of the electrolytic capacitors failing in the pin cushoning amp section, and probably in part of the scan amplifiers.

To service this will require the proper training and set-up to troubleshoot the set.

Take the set to a service center for an estimate. The cost can be at least an hour or two for the labour, and then the cost of the parts on top.

Hourglass picture. Panasonic CT-35G30T The picture is hour glassing from the sides. Starts to flicker back to normal after 1 to 2 hours. Getting progressively worse. Takes longer time to reach normal...

This is caused by bad solder connections in what's called the pincushion correction circuit. Some of the transistors get quite hot, and over time the solder connections to the TV circuit board become intermittent. When you tap the set, it causes them to make contact again so the picture is normal, but then it goes funny again. Resoldering the connections would take care of this problem. I would suggest calling a professional in to make the repair, which would cost far less than a replacement TV.

Hope this has been helpful, and thanks for using Fixya!

TV comes on but after a while there becomes a hourglass shape on screen. It is drawn in 1/2 inch on the sides. Can this be fixed cheap?

yes. has a pincushion circuit problem. since tv works and then starts to bow, its a bad solder connection. when tv warms up the metal expands and looses connection. when cold, the solder constricts and unit works fine. just solder deflection area. you can probably tap on board and locally find area to solder.

Hour Glass picture on a RCA TV F32632SB

I looked up this model and found the following electolytic capacitors to be the most likely culprits within the pincushion circuit. Check these first. The starred one is the one I have replaced in the past to resolve this.

C4851 10ufd 50V
C4853 10ufd 63V
C4854 2.2ufd 100V
C4855 2.2ufd 50V
* C4862 100ufd 25V

Good luck,

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.
