Question about Projection Televisions

1 Answer

I have only the top line of a multi-screen picture (4 small boxes, all the same), below which are some colourful flashing very small boxes, and the rest of the screen is blank except for a big black box. I, or my cats may have caused the problem, but could you tell me if the whole TV has gone? It is only 2 years old. I am a technical klutz and do not know what I am doing.

First turn off the closed caption (CC on remote) then make sure the picture in picture is not activated. turn it off.( PIP button on remote). If that don't help un plug the tv and then plug it back in after a few minutes.

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

You have a completely different problem. The screen voltage for the blue picture tube is slightly too high on your set. This will put fine lines in the background of the picture, called retrace lines. This is very common and easy to correct. Remove the front speaker cover and the access panel behind it. Look inside and you will see a black box with six controls, each control having a little white glue on it. This is the Focus/Screen block. Three controls are labeled Focus and three are labeled Screen. The screen control in the center is for green but I am not sure if the screen control on the left or right is for blue for your model. With the TV on, set it to VIDEO 1 but do not connect anything to the VIDEO 1 jacks. This will produce a pure dark picture, showing any faint lines in the background. Choose one of the screen controls and increase (turn clockwise) it slightly. If the blue lines do not get brighter it means you are turning the red screen control, so put it back where it was and choose the other screen control. When you find the blue screen control, decrease (turn counter-clockwise) it until just when the blue lines are gone. If you want you can check that the red and green screen controls are set to just below the point where their faint lines are visible. When done, replace the panels and your picture will be back to perfect.

MikeNJ1964 was exactly right! I have a Sony KP-65WV600 that had horizontal green lines that showed when the picture was darker. I had to remove 3 screws on the right and left side of the tv holding in the speakers...carefully pop out the middle panel from the clips holding it in....remove 4 screws from the cardboard in the middle and remove the cardboard. I then saw the six screws. The adjustment screws were the three below. I turned the middle screw until the lines dissapeared. I tried the left screw and blue lines appeared which I then adjusted away.
THANKS a bunch. SAVED me money!!!

Horizontal Lines


sounds like you are seeing retrace lines. you will have to adjuste the screen control. (it would be like a master brightness.) you will have to removed the front bottom plastic from the tv, look for 2 to 4 screws. then gently remove the front. sometimes the also add velcro to help hold it in place. now you need to remove the small plastic or wooden panel/door. in the upper right side you will see a small box with 6 controls.i do nor remember if the top 3 controls are for screen or focus, use a flashlight it is marked on the box which is which. adjusted the screen control to the left slightly to decrease the color you need. the green is the center control. like you said it is more noticable on dark screens, so try & adjust it in a dark romm with a drak seen. good luck.
