Vertical lines on an LCD screen are not a good sign. This usually means that your screen is going bad.

I have a good picture then it goes horz. with static and then a good picture and then a horz. lines and static about every sec.


The horizontal line indicates failure of vertical section, checkout the output capacitor of vertical-section connecting to the yoke (vertical) for any loose contact, dry solder, capacitor wear-out.
Need to check the register and filter capacitor that powers the vertical-section.

Vertical line in center


If the line is "vertical" then the vertical circuit sounds OK. The problem would be in the horizontal deflection.

Check yoke connection and solder around horz defl circuit.

If the line is horizontal then I would suspect the vertical IC.

I got white vertical line running down a plasma display panel . they are close together that you cant even see on that side of the tv. on a closer inspection they are blue-green-red-blue-green-.... but...


A vertical line running down a plasma display can be caused by :

faulty buffer module.

Fauly sustain card.

Faulty plasma display.

Try unplugging power cable and see if this helps, if it does not , then you will need to call a technician.

In that case call the support number listed on your owner manual.

If warranty has expired, ask for a warranty extension, if available. this is cheaper than repair cost, and will cover the repair.

Re: ask assistance


caution reduce brightness to protect crt burn. vertical line with sound ok is due to 1 deflection coil connector loose or wire going to horz.coil disconnected. 2 capacitor going to h/winding loose or defective. 3 print break from eht to h/coil.
