Thin line across screen

I used to be able to tap the TV on the side and the picture would show full again, but now, I think it's dead. Sound and remote works.

Sounds like cold solder joints in the vertical circuit and also check around the yoke plug.

Hi there My Sansui TV screen started showing thin white horizontal lines across the top of the screen. All of a sudden the screen starts condensing the picture into fine lines across the middle of the...


It is an indication that you have a problem on the vertical section on the main board. The faulty parts is the electrolytic capacitor which affect the linearity of the screen that's why you encountered that kind of problem.
I've advice you to send it to repair shop or look for a qualified technician to isolate the faulty electrolytic capacitor and do re-soldering for some dry joints on the main board.Once replaced the capacitor your unit will back to normal again.

No picture Thin line across middle of screen


Hi,

Most problems indicated by your description involved the Vertical IC. With your post "tap...pop back up" signifies a loose connection or to be more specific a cold solder. I suspect that no part(s) need top be replaced but would however require re-application of heat with the use of a soldering iron.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Toshiba 36AF43 36" just has white line in the center


vertical output IC has loose solder joints.if you continue to let it operate this way it will etch a burn line across the face of the tube so discontinue use.

Tv not working


this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!

Blue tint and lines on screen.


Those lines sound like "retrace lines" and several things can cause them. The most common are shorts inside the picture tube and shorted semiconductors in the video driver circuits. They can also be seen if the blue screen voltage is too high or if someone has tampered with the screen voltage control.
