I have picture at the top and verticle lines at


Your panel needs replaced. Half a picture, top to bottom, provides a quick diagnostic. You panel has a Timing Control (T-Con) board failure. Watch out for part cost, it may be cheaper to replace the TV rather than repair it. I hope this helps.

Vertical lines half way across screen.


Try performing a factory reset of the TV2_bing.gif. Go into the service menu (Press, then release the INPUT button on the remote, then key in 2580). Scroll down to "Other Settings", then go to "EEPROM Init", then press enter, select YES and press enter. This will reset the TV to the factory defaults. If that does not work, send it back for repair. Good luck!

You have vertical output problems.There is distortion at the top because of a faulty vert. output i.c. or a faulty electrolytic capacitor.It's possible there may be a problem at your yoke also.It needs a professional repair.

You have a bad vertical output IC or a bad capacitor(s) in the vertical driver or output circuits. Not a job for the user to do unless you have the proper tools as well as a service manual. Good Luck

Top half of screen black


The vertical circuit is going bad,this is the one in charge of opening the picture up and down,try taping on the side to see if the picture reacts ,if it does your set has a loose conection and the vertical IC will need to be resoldered only but if it does not react the IC will have to be replaced,if you are familiar with tv service this will give you a place to start but if you are not be safe and seek the help of a servicer,please let Us know how it goes.
