Re: green lines on my Sony projection

Those are called retrace lines and they are the result of the blanking pulse not having the desired effect. This could denote a problem in the Horizontal section of the TV. In this case the green gun is not being turned off as it goes back to the left side of the screen.

Limes across screen when first turned on, by turning off and on sometimes fixes it, what could cause that problem?

If the lines are colored or even look 3d it is a convergence problem--if other lines it will depend on what they look like and what the model number is.

Come on then line horizal across screen then turs off

Horizontal line (up and down) is know as horizontal collapse. This is usually located around highvoltage section of the circuit. Because this circuit depends on certian frequencies and voltage protection circuitry will shut the set down. This will need a trained tv technician to fix this and can be expensive depending on the parts needed.

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.

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.
