you need to replace y-sustain board.

SOURCE: Screen Problem

hi....Your tv picture is managed by several boards, the two specific ones are the ysus and the xsus. The Y controlls the horizontal pixelation and the X the verticle, if you are having horizontal problems then its the Ysus thats faulty, on this particular set, the Ysus board has two accompaning buffers that are particularly troublesome. I've had more than one of these sets in the shop recently with the same ailment.Sounds like your buffers are starting to go out. The screen is split horizontally by the two long skinny buffers attatched to the Y main, if the bottom one has one leg in the grave you'll be getting a partially black screen or no picture at all. The colored lines running through the screen are more typical of a failing buffer. Are you interested in taking this set apart and putting a couple hundred into fixing it?  When buffers go they usually take the Y main too. Worse case scenario you're gonna be out about $350 dollars to fix it yourself. Best case, a ribbon is loose on the bottom buffer and with a dismantle you'll be able to connect it again..

thank u rate me!!

The lower "Y Buffer" board is defective. Best repaired by a technician, or contact Phillips support for the part if you think you are able to replace a small circuit board on your own.
