Look for the vertical section of the printed circuit board.there is a vertical driver ic and it is maybe bad...... either the soldering,or the ic.
if you bang on the tv and the picture regains deflection,there is a bad solder joint or connection.
there are a few capacitors too 100mf 25 volt 4.7 50v also 22mf at 50v

While watching tv half the screen goes black


Download software from the Phillips web site. Use a usb flashdrive to transfer the download to the TV. This worked well for us and our picture is better than ever.

Screen split with black bar through center, top of picture shows in bottom


It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
