The box may be causing this, many now have adjustments in their menu for centering and height and even width of the image.

It of course can be a problem in the set but that would show even with the box removed.

ALways check for connections. Caps usally get better with heat not worse, but maybe. with out the resources of a service center id say if you suspect a cap change them all i would guess though more likely the IC or a connection becaues you say it is good cold and bad hot

A vertical line means the line is up and down in the middle of the screen. That would indicate that the vertical IC and the surrounding components are working perfectly. A vertical line as described is the result of a lack of horizontal deflection (to move the beam from side to side) Since the high voltage is obviously OK, the problem is most likely a bad solder connection in the horizontal yoke circuit. Examine the bottom of the PC board in the area of the flyback transformer, and yoke connector (has four wires Red, Blue, Green, Yellow).and the pincousion coils, capacitors, etc in between. Flexing the board in that area may cause the problem to come and go. Resulting arcing should also be visible. BE CAREFUL, as hazardous voltages are present in the circuit!

Height of the picture is less than normal? If so, check and replace all the electrolytic capacitors at its vertical sweep output section circuit. Replace all of it at one time. There will be 5 or 6 of them.

Verticle lines appearing near top. Reminiscent of more extensive problem a few years ago that repair man said were related to electronic equipment used nearby such as vacuum cleaner. He fixed it with...


Case 1:
If the horizontal lines are red, green or blue or white, and are slanted about 15 degrees up going left to right, they are "vertical retrace" lines. These are caused by the beam current in the offending gun being left on while the vertical deflection is retracing from the bottom to the top on its way to start drawing the next frame. The usual cause is the CRT screen setting being too high (too bright), but (rarely) it could be something wrong with the vertical blanking circuit. Since it is dependent on vertical position, I would check the power supplies feeding the vertical deflection circuit and the CRT bias voltages, especially if they share the same filter capacitor.

Case 2:
If the lines are true horizontal, and colored similarly to the picture (sometimes alternately white and colored the same as program material), the top of picture is folded over itself because of over-voltage distortion ("clipping") in the vertical drive. In this case, reducing the height of the picture also reduces the fraction of the picture with the lines, and may eliminate it. If you are unable to get a full-height picture without the lines, then you should check the vertical deflection circuit for leaky capacitors (also check the power supply voltage going to it).

Case 3:
Several times I've observed bright white lines with random interruptions at the top of a picture supplied by the local cable company. These often occur on one or a few channels for a time (once or twice I've seen it on all channels), and go away after a while. This is a glitch in the cable service.

Case 4
You have a zone of weird colors at the top of the screen. This is probably caused by magnetization of the shadow mask inside the front of the picture tube that is not being erased when the TV is first turned on. Check to see if somebody left a magnetized object on top of or above the TV (look behind the set also). If you find something remove it, turn off the TV, wait a few minutes, then turn it on again. (Explanation: the TV has an internal demagnetizing coil that operates only when you first turn it on. It uses a self-heating temperature-dependent part to gradually reduce the alternating current going through it to override and "fade out" any stray magnetism in the shadow mask.) If the internal demagnetizing (AKA degaussing) coil isn't strong enough, you'll need that "ghostbuster" gadget again. If you don't find an external magnetic source, the internal coil may have slipped out of place at the top of the picture tube and is too far away from the shadow mask, or something is wrong with the degaussing circuit.

If none of these cases match what you see, try a more detailed description of the lines and I'll give it another shot.

Green vertical line on videocon 42inch plasma tv


Hello Depending how wide the line is their could be two possible causes.
I have two questions for you.
1. How wide is the line.
2. Does it run from top of screen to bottom of screen?
If the line is thin a single strait line then it is possible the PDP has gone Bad (Panel). (Screen). The screen will to be replaced.
If the line is at least 2 or more inches wide then its a buffer board which can be replaced. LG calls this board Hand insert Boards or display driver boards..

Panasonic TV - no picture, but sound is ok


 

 

it is due to vertical section failure.

  • before you start any work reduce brightness to avoid crt burn.
  • please check some loose contact or loose connector.
  • check supply to vertical section
  • check parts in vertical output section
  • check vertical ic.
  • hope this will help.
  • good luck.

My LG tv has suddenly got a problem with the picture. Whilst watching the tv with no problems at all, the picture was suddenly reduced to a thin vertical line down the centre of the screen and an awful smell seemed to come from the tv There is a short ckt in your tv in horl. section. 1 isolate power from horizontal section. 2 check for normal output from power supply. 3 check parts in horl output section a hor.output transistor b diode & cap in h/output trnsformerckt. c check for print. d if all are ok check for eht transformer. e if every thing becomes then reconnect hor output section supply. f put on the set.

Vertical rolling


Does you set have PIP (picture in picture)? If it does then the PIP module has a bunch of capacitors that have gone bad (dried out and leaked) causing you to loose vertical sync. Vertical synchronization is what locks your picture keeping it from rolling. Even if you don't have PIP then still you have a vertical sync problem. The set would have to be checked by a tech to find exactly what's happening. Stargazer
