53" sony projection -picture washed out w/ green horizontal lines


It sounds like your Green CRT ( picture tube ) is shorted. That's the one in the middle. Sony had issues with there tubes in those years. Sorry for the bad news. Even if you could locate the tube, it will be a matter of time before the Red or Blue does the same.

I have a KV27FS210 sony wega trinitron tv. It turns on and has a single horizontal line across the center of the screen then buzzes shows a continuous zigzag line from the top to bottom of the screen with...


The single horizontal line is a problem with the vertical circuit. Look for a small flat id attached to a heatsink that should be marked LA7837 or something similar. Try resoldering the pins of this IC first. If that does not resolve it, replace the IC.

Keep us posted.

Horizontal grey lines on TV


Sound like you have to turn down the G2 (screen)controls. They are turned up too high.
