I have 2 lg repair the same trouble vertical horizontal rolling


Vertical or frame rolling indicates adjustment of the frame hold is required or perhaps there is a synchronisation fault.

Breaking of the picture in the horizontal plane is caused by the line hold requiring adjustment though the symptom can be connected with interior or exterior signal problems or perhaps a power supply fault, especially where both the line and frame are affected together.
It is probably a task for an engineer or at least someone with access to the servicing instructions.

Picture is like dull. i ajust the focus in the flyback then comes like fine vertical lines


The trouble is not the focus of the flyback transformer, the one you adjust is the screen try to return the original position. try to check the crt socket it is connected to the picture tube if you see something in the pin that is color green it is corroded try to replace it with the same type of crt socket.

Vertical line at edge of AV1 channel


hi! he might have adjusted the vertical hold and height including the linearity. normally on the board you would see a trimmer resistor with a label v-hold this is to stop the rolling, v- height for the size of the picture. and linearity for the evenness of the picture from top to bottom.

Headlights needs ajusting


on each headlamp assembly, there will be either one or two plastic nuts that you can turn.

If you only have one nut on each, that will adjust the vertical aim of the headlights.

If you have two nuts on each, one will adjust the vertical and the other will adjust the horizontal.

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

TALL PICTURE


Hi,

On most TV units, there would be two (2) adjustments that affects your concern:
  • vertical Linearity (VLin); and
  • Vertical Height (VHt)
However, newer designs no longer have these adjustments since they are automatically done by the circuitry. If for some reason height is incorrect in such a system, then chances are that there is a leaky/defective capacitor in the vertical section.

Hope that this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

The same is true for rear projection. There may be an adjustment for vertical hold in a hole in the back of the cabinet.
