Question about Westinghouse Televison & Video
After 3 to 5 minutes, it changes color and goes black; then a few minutes later, it happens again.
I am sorry but assuming you have an LCD or Plasma TV this means either A) your display cable (internal) is bad or B) the display is toast. I would try hooking up another display to see if this occurs on that display. If not you need a new display.

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.

remove the back of the tv.disconnect and reconnect the ribbon cables into your buffer pcb.if this does not correct the problem replace the buffer pcb in that location where the screen is going black.you also could have
a defective panel if the buffer pcb does not correct your problem.
