You have bad capacitor(s) in the vertical circuit.

SOURCE: horizontal lines on picture

Can't advise on entering setup but the lines may be due to the maladjustment of the brightness control on the flyback. There will normally be two adjusters, one for focus the other for brightness.

SOURCE: I have vertical shifted up from bottom and foldover from top down

This is caused by a defective capacitor in the vertical circuit. If you can solder, you should be able to fix this your self. Let me know if you wish to attempt the repair and I will supply additional details and instructions.

SOURCE: Sansui sv29281 has a top foldover. I have replaced a faulty 1uf electrolytic cap in the vertical circuit but still have a problem.

Check and replace all the electrolytic capacitors at the vertical scan output section circuit at one time. Check the all the solder terminals to the vertical scan output IC for loose soldering.

If this were a degaussing issue then I would expect to see red, green, and blue but with distortion. That isn't what you're reporting. As has been suggested already, you likely have a component area (like vertical or horizontal sweep) that is malfunctioning because of a failure. The failure could be system voltage oriented or a component board or combination of both. Here is the bottom line, how much are you willing to spend to fix an older TV? If you aren't willing to spend a few hundred dollars then consider why a repairman would want to work for less? By the time a technician puts the set on his bench, opens it, and does preliminary system check you've got an hour invested. If a system power voltage failure caused other components to fail then the problem along with cost to repair quickly escalates.

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.

Half a screen


The picture on your TV screen is driven from the center to the top and bottom of the screen by the vertical drive circuit. The fact that you can see the entire picture means you have a problem called foldover. This is caused by a failure in the vertical drive circuit where the vertical saw signal is altered by a component failure within the vertical drive circuit. You cannot solve this problem but any good repair shop should be able to correct the problem at a reasonable cost.
