This is a failure of the vertical deflection circuit. If you can solder, you can fix this yourself. If you wish to attempt the repair, please update this and I'll provide additional details and instructions.

    Look for a small flat IC attached to a heat sink that is marked LA7838. That is the vertical IC. Try resoldering the pins on that IC first. If that does not resolve the problem, replace the IC. There may be capacitors in that circuit that need to be changed as well, but those parts will alter the picture not prevent any vertical sweep. Update this with your progress and we'll address any other problems if and when they occur.

I have a CRT tv and the picture is just a thin band in the centre of the picture tube. The sound is ok


That is called "Frame Collapse" because the picture "Frame" has collapsed into the single horizontal line.
It may be caused by dry joints or output failure of the frame output stage.
A fairly inexpensive repair.

SAmsung has two white lines across screen with no picture


If the 2 white lines are in the centre of the screen it sounds like you have a fault called 'field collapse' . The 'x' or horizontal circuit on the tv deflects the beam across the screen which in your case is ok because the line runs across the screen ok. The 'y' or field circuit on the tv deflects the beam down the screen. Without a circuit diagram for your tv i cannot point to individual components.

Still waiting for a solution from Abrsvcs


I'm sorry. Based upon the lack of response on the original posting, I was not aware you were waiting. The only update there was a TFT rating. I will look up the specific parts tonight and update the original posting with the details and instructions.

it is due to vertical section failure.

  • 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.
