Question about Standard (CRT) Televisions
My Symphonic Model number WF2702 has only a thin white line across the middle of the screen. I am thinking it's something in the verticle hold module?
The vertical hold keeps a normal picture from rolling either up or down. You don't have a normal picture (raster) here.
The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace.
