I have found through my research that the problem is most likely Back Light Inverter board or the P/S board. The P/S board Circuit Card Assembly or P/S CCA as I call them in my line of work, provides the correct voltages to the Back Light Inverter. The Back Light Inverter CCA then provides the correct brightness and contrast required on the screen. I am almost certain it is either one.

SOURCE: colored vertical lines with sound no picture

im afraid to say that your display has gone the best thing you can do is call the supplyer of the tv if its under warranty or call samsung. the cost of a new display will be 400 - 500 pounds so you may have to buy a new set.

Visual transparent lines at top of picture


You have a vertical output circuit problem. This was common for Philips' sets. Have a repair shop check it out. Should not be too expensive to repair.

P42W46X Zenith Plasma - No Picture - Mostly Yellow on screen


Mine looks like too, but the line running across isn't on my set, picture looks like this, and the sound works fine. I took the tuner board all the way out and turned the set on and it did the same thing, then I unplugged the top wire on the board next to the tuner board and the screen went black. plugged it back in and the screen came back with the scrambled picture. Anyone know why? Bad mainboard maybe? the left of the tuner board?
