This is one of the common problem with this unit.

Please tell me if the lines appear on all inputs ? DVD, TV, Video 1,etc
Are the lines showing in the TV menu ? (if it is in that area)
Sounds like a problem with the bottom row of buffer boards,
ribbon cable connectors or the panel itself.

This is an internal failure and needs repair / replacement of any of the 5 components / boards viz

1. Ymain - supplies the scan voltage to light the panel.
2. Buffer boards (upward to 5 in a set 3 on the bottom and 2 on the side)- Supply the data and connect the voltage to the correct pixels in the panel
3. Logic board - the brain it takes the video and turns it into the signal required to instuct the buffers which pixels to light to make the picture complete.
4. Power supply - self explaining
5. The X/Z sustain responsible to light the panel in black and clear the picture between each frame

You need to have electronics repair experience to repair this. Kindly take all the precautions as i could only guide you.You would need multimeter and might need to do soldering.

Let me know,so that we could proceed.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Please check around vertical outpu IC for bad solder joints and you can try to replace the electolitic capacitors in vertical output line. Check if vertical plug (which comes from deflexion coils) is well attached in place.
