Sound like your Y-Sustain board has one foot in the grave. The Y upper buffer and Y lower buffer boards go when the Y Sus Goes too...

Check its vertical output section circuit for any component damage or loose soldering terminals. Check the solder terminals of the vertical output IC. Resolder all the suspected solder terminals by applying al little more fresh solder, without making any solder bridge short in between adjacent solder terminals.
If this do not help you, replace the vertical output IC. Lose of Vertical Scan is the problem of your TV.

Resolder the vertical IC and replace those capacitors near and next to your vertical IC. If the horizontal line still appears, you may have to replace the IC. Thanks for asking and be caredful!

The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv . 

Vertical hold circuit is failing.

Check capicitor in vertical hold circuit. You should have solid knowledge of electronics repair before attemping repair. TV's can emmit harmful radiation, and produce voltages up to or in excess of 30kV.

Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.

resolder vertical output ic pins

refrigerant, set is in vertical collapse which requires the replacement of the vertical output IC, probably going to need a tech for this one, questions? e-mail me, BMW Rider

• your problem is in the vertical output section as you have already mentioned that compressed down to 3 inch
• if is is some times then you will have to check
• loose contact in electrolytic capacitor in vertical output section
•  it will be dry or some print cut must be there.you solder it.
• it is best thing to replace all electrolytic capacitors in vertical output stage.they are hardly two or three.
• it is a common failure,& not a major problem.
• as per location of the suspect is concern it in the section from where the wires are going to crt neck.
• hope this will help
• good luck
