Verticle hold transistor?

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?

    Ok, My theory as well, I have a bad transistor somewhere in the verticle control. I am 100% with you-- verticle output transistor. How can I tell which transistor is bad?

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.

Good Luck!

it might be due to static on the notebook
turn off the notebook and then remove the battery from the notebook press and hold the power button on the notebook for 4-5 sec and then put the battery back and then turn on and check
if the line is still there check it in the safe mode or in BIOS if its still there then replace the screen

Horizontal line across screen


HELLO
This is called "Field Collapse". Line collapse is different (a single vertical line) in the centre of the screen.
But field collapse is usually a fault in the field circuit (possibly a field output IC has gone short circuit) or electrolytic capacitors have dried out. The same can happen in a CRT TV - looks as if LCD panels are the same way! I think you will have to take this to a service centre.
GOOD LUCK! (:-)

Thin horizonal line in middle on dark screen


The several thin white lines at the top of the screen is the warning that the vertical output IC is not getting the boost voltage it needs to run correctly. The IC cannot operate for long like that and shorts out inside, which is when the vertical collapses altogether and you get the thin white line through the center of the screen. The good news for your son is that he had nothing to do with that, and it has nothing to do with the cable F connector. The set needs to be serviced by an experienced tech who will restore the boost supply and replace the vertical output IC, and when I do that I charge $75 but techs in your area will vary, so be sure to ask around.
