Question about Sony KP-51HW40 51" Rear Projection Television

Horizontal Lines Hey, I have a approx 4 yr old Sony KP-51HW40. I have blue/greenish horizontal lines which are noticeable during darker sceens. They are present during both when viewing DVDs and cable TV. They are not noticeable durng brigher sceens. They do not distort the picture. Is there anything I can do or do I need a repair service? What could be the cost to fix this problem? Thanks

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.

Sony Projetion TV has horizontal blue lines across the screen

It is hard to tell from your description what is wrong--confirm actual model number for me.

I am going to attach some photos of what CONVERGENCE troubles look like--they may or may not look EXACTLY like your set but if you have something similar I can help you with more information.

Sony KP-51HW40 51 in. Rear Projection Horizontal lines

Don't waste your time - go out and get another TV. Chaulk it up to that we have all been scamed by SONY. They knew about the problem, did not choose to make things right. They have become the Fat Cat with the attitude that no one can hurt them. We need to show them that they are wrong and boycot their products. That is the only recourse we have.

No picture..

hello,,,,,
Picture mute is activated ,it can be vertical amp faulty or one of the c.r.t drive faulty,therefore the mute circuit is active.Increase G2 voltage for the any of the three c.r.t and notice screen .Vertical amp is faultry than you will see horizontal line across the screen and if you see full screen with flyback lines ,means c.r.t drive is having fault.isolate one by one c.r.t drive.
