Insignia 32" TV Thin line across screen 1-2" from top


This is usually caused by bad capacitors in the vertical circuit. If you have an electronics background you should be able to find the defective ones with an ESR tester .

Tube TV - one thin horizontal line of bright light


Vertical defection failure. Common failure. Pretty easy to repair ($50-75?). However, my general rule of thumb is not to waste any more money on TVs over 10 years old. Too much other stuff in there ready to fail as well.

Sylvania 27 inch stereo flat screen tv


This problem sounds like a short inside the picture tube itself unless a driver transistor failed that drives the red gun in the CRT. You may have to take it to an authorized repair facility if the picture tube is still in warranty.

Thin Horizontal line through tv blank screen.


Replaced vertical IC ( la78041 ??>.. Or La78040 ). Look for born resistor beside IC. Replaced capacitor 100uf 35V too!!! Good luck !!

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!
