Hello, It sounds like the deflection circuit is faulty. Usually,but not always caused by a problem with the switch mode power supply. It could be as simple as a capacitor or zener diode. Either way unless you are a technician I would get one to help you. Shouldnt cost any more than around $100-$180. As far as the pix goes,that sounds like the lamp they use to project images,around $400 fitted. Hope that helps.

I Have Sound . But I have no picture.

We know now that the TV is not the problem as you can play a DVD with sound and vision - this means it is likely the configuration - the DVD is likely on component so if possible (and if you have an HD set top box) then you could try interchanging the leads. You could also have a faulty HDMI cable so if possible change it with another one. If your TV is not HDMI or Component and you are using RED / Yellow / White then make sure they are configured correctly as it is possible you may have sound on one chanel and accidently put the composite video in the wrong hole.
