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

1 Answer

Sony KP-51hw40 picture messed up but sound ok

I have a Sony 51" tv that there are lines going through it like when the vertical and horizontal needed to be adjusted on the old picture tube tvs, but when I pull up the menu it is fine but the feed is still like that. Does not matter what feed I use whether it be reg tv or video 1, 2, 3, 4, 5, or 6. Tried adjusting the lamps but did no good so reset them back to where they were. Any ideas?

Screen shakes / jumps vertically on my Sony KP-51HW40


The jitter is called a vertical sync problem. The problem is on the "A" board. It can be replaced or rebuilt but will be quite expensive to service.

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.

RED AND GREEN LINES HORIZONTALLY ACROSS TV


This sounds like you may have bad picture tubes. Most likely the green and red tubes. You would have to have them replaced and realigned. I would call a Sony ASC and get an estimate to verify this. An onsite service call could verify if this is what's causing your problem.

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.
