Vertical scan output failure. Check and replace damaged components at its vertical scan output section circuit. Check for any loose solder terminals at this section circuit. Contact any service technician. http://electronicshelponline.blogspot.com/

SOURCE: Picture on RCA TV shrinks to a horizontal line

Hello,
Sounds to me you have a cold solder joint ( loose solder connection ) on the printer circuit board around or on the vertical chip or on one of the vertical capacitors. You may also have a bad vertical chip or a bad vertical capacitor, but I doubt it since it did come and go. I'de get a soldering iron and some solder and touch up the connections. I will remind you that you need to always excersise saftey by making sure, before removing the back, unplug the TV from the wall, and use care not to come in contact with the large red wire going to the back of the picture tube as the picture tube can be turned off and still store lots of voltage ( up to 35,000 volts). Always stay safe and when soldering, use care not to run solder across places that will make a short.
Good Luck and I hope this helps

SOURCE: 6 horizontal lines

I would look for a Vertical circuit failure. Most likely is the vertical output IC and or open resistor off the hv transformer. Definitely look for any loose solder connections around the Vertical output IC.
Hope this helps,

SOURCE: tv screen is black except for 1 horizontal line of color

The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

Hi, I have a Tedelex EC29187 Television it have only a horizontal line in the middle of the screen, I opened it and looked for physical damage around the vertical defflection IC, but it show nothing so...


Ur tv it is taken aparts wright now?Yes.Plug in ur tv to see the problems and take the hard end handle of the screw driver and taps around the vertical deflection ic for cold soldering joints,will require resoldering the ic,if the vertical hold flickers or bounced back to normal.No bounce back vertical hold check all the sorrouding capacitors transistors resistors for dead components parts to be replaced,if all the sorrouding parts are good,than that vertical deflection ic it self it is dead and require replacing.

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck
