What is the cause of my 14inch videocon crt tv appears only a single vertical line in the middle


The image on a CRT TV is produced by a beam of electrons which is controlled by a magnetic field to move the beam top to bottom and left to right. A single line suggests that the vertical deflection is working but not the horizontal deflection (left to right). There are a number of components associated with this and requires a competent TV repair engineer to fix. Better to to buy a new 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.

Screen only shows horizontal line


if line is left to right in middle of screen the problem is in the Vertical deflection circuit---could be either a soldering problem with the vertical output ic or a bad part in that circuit. If this has been helpful please give me a vote.

H line problem


I think you are describing 'no vertical deflection.' If all you have on the screen is a single horizontal line, the vertical deflection circuit (or IC) has died. Unless you have service documentation on hand, I can't give a part number to replace but this is typically not an expensive failure and if the set was OK before, it is worth having repaired.

Horizontal Light Only


If you have a straight horizontal line in the middle of the screen the vertical deflection has gone out. Itll need to be repaired, the vertical deflection IC is bad. Hope this helps.

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

Horizontal line in the middle of the television


From your description of the problem, there seems to be a Cold solder in the Vertical Oscillator or Deflection Coil circuits.
If you know Solid State electronics, and are good with a soldering Iron, sure u can do this yourself.
U gotta trace the Vertical section components and locate the cold solder. In most cases it will be a loose connector from the Deflection coil to the main PCB.Also check for the soldering of the Vertical output IC.
