It needs trouble shooting but try first minor option if you can open your flat TV then re soldered parts. in this case the problem was in video and color section try to look cold solder parts like IC, resistor and capacitor re soldered all this.then your last option is to check leak or defective parts which may cause color interference in your screen.

We have an older Phillips Magnavox tv. The tv will turn on & we will see the picture for a short time but then the screen turns grey. We still have sound, just no picture. Also, the green power light...


Hello, the grey screen could be due to a missing 220Volt source which feeds the color (RBG cathodes)inside the CRT(picture tube). When this happens the beam current inside the CRT goes high in a matter of second, thus triggering the beam current protection circuit(blinking green light)shutting down the TV. Repairing the secondary voltage source is necessary to get the TV working normal, a good technician should be able to repair it for between 80 to 100 dollars parts included, except a picture tube, which could be also the cause of the problem(K-A shorts).

I have a KP-65WV700 and the screen looks a lil to green


OK, I'm the guy that was having the same problem, but had a blue tint to the screen. I also had blue lines running across the screen, and when I followed the steps below that were posted by another user not only did the lines disappear, but the blue haze vanished as well. My tv looks like it's new again, so you may want to try this:

I have fixed this several times on my KP 65WV700

As Slinteriors posted if it is a thin curved line you need to adjust the screen control, it's sorta like a brightness for each color, and if one color is too high it will produce a thin curved line.

The best way I have found to get to the controls is by removing the lower grey speaker cover front the front of the TV. There are 6 screws if i remember, 3 on each side. Then it snaps off, seems like its going to break but you have to pop it off pretty good.

Once its loose you have to remove a cardboard like cover plate in the center that will give you access to the small controller board.

Now be very careful while experimenting on which knob controls which colors. Turn them very slow, if you turn to fast you will cause your TV to shut down. If this happens, turn the adjustment back to original spot and turn TV back on and take it slow.

Adjust the correct color until the line just goes away. Its easiest to do this with a black screen.

When turned on only gets a straight line of color in middle of screen


You lost your vertical sweep. most likely the vertical output IC or a power supply source is the problem.

White arched lines appearing on dark/black screens.


it sounds like you are seeing the vertical retrace for all three colors together (white). Its possible that all three screen adjustments (red, green, blue) are off, but I suspect a problem with the screen power supply.
there is also a recall on this set
