Horizontal line shows problem in Vertical Deflection area of TV, please check Vertical Output IC and its voltage supply. You didn't mention model and brand name so I gave you general information for that problem.

My Sony KP-65WS500 is flashing blue screen and horozontal lines and now has a black box about 1ft x 1ft box in screen. It will do this for about five to 30 seconds and then cuts off. I can see the picture...


hi,

Remove the front cover or the back. You need to look for the color gun it will look like a small box with 3 screws. Slightly turn the screws to adjust the color in your case in and out blue and arching lines.. Now the box sounds like a picture in picture function.. Would have to see it. Now it it cuts off power after 5-30 seconds after doing this you could have a bad capacitor on the power supply board which is sending the set into fault protection. A Bad cap with be poped at the top (X) -Top view of a cap should be flat. NOt rasied or poped.

Best Regards and Semper Fi

This is a vertical-deflection problem. Try to adjust the vertical (height and linearity and hold) controls, which should be screwdriver potentiometer controls on the back of the set.

If this does not work, a defective component in the vertical-deflection circuit will need to be repaired.

I hope this helped you. :)
