How to solve horizontal lines on a CRT TV monitor and what could be the possible courses for it


Monitor horizontal lines problems usually caused by a defective vertical output/driver ic. A missing supply voltage to the vertical output ic may caused similar faults which is one horizontal line across the display. Dry joints and missing vertical output pulse from vertical oscillator ic also could contribute the same symptom. If you discovered that the protection resistor (usually from 1 to 4.7 ohm) open circuit or burnt, then replacing it won't solve the problem. The resistor burnt or open circuit was due to a short in the vertical output ic. Thus you have to replace the vertical output ic and the burnt resistor together before you switch on the monitor.

Vertical size of screen is bad. very big. please solve this problem.


You have too much vertical scan amplitude this could be due to higher voltage on dc line to vertical amp or broken amplitude control , maybe short circuit capacitor on feed to scan coils, or transductor open circuit windings , could also be open cct in negative feedback loop.

RCA 27 in has white horizontal line going through the middle


this symptons is caused by a breakdown in the vertical deflection circuit. hence, the trouble may be in the vertical oscillator, amplifier or output circuit. in most modern tv the vertical ic is usually composed of these said circuit inside. the ic have many pins, standing on a heat sink and smaller in size. try to check also the capacitors surrounding it. sometimes leaky capacitor may cause this problem. good luck!

My 15 year old Toshiba Televisiononly shows a narrow horizontal band in the middle of the screen. Sound OK.


Hiii fairley,

You aren't specsificly dercribe yor tv set.
For common TV horizontal problem ;i.e : White line accross the horizontal screen, horizontal band,etc..it's can solved by replacing the IC Vertical/Transistor, and olso to replace the cap nearest the IC.

For common TV Vertical Problem :i.e : White line at the center of the screen (top to bottom),Vertical band,etc...It's can cure by Replacing the Horizontal IC/Transistor,and offcurse the cap's.

Tha's what all I know....

Hope can help you to solved the problem.

Thank's

Vertical line across picture tube on my Symphoic model WF2703.


Is it just folded over with a thin line of light thru the middle of screen. It is a vertical collapse. Vertical Ic is loosing connection with the board or failing Already. resolder first then see if it can actually solve it. If not check capacitor or neighboring components within vertical circuit or replace the vertical IC and check if this solves the problem.

If your not inclened in electronics, have it service by a qualified one.

SanyoTV-blk screen w/thin line of light across screen great sound


Your Vertical Amp is probably Blown (bad) , but before you change that check all capacitors around the vertical amp IC and / or resolder resistors and diodes around vertical amplifier.
And NO it is NOT the Picture Tube
Good Luck

HORIZONAL LINES


that is because you have a defective vertical deflection circuit, check all the caps and if that does not solve the problem replace the vertical output ic

good luck

It looks like the vertical amplifier IC401 is defective. If you have soldering/desoldering skills you can change this part yourself. Also you may have to change C471 (.01UF 50V).
Good Luck.
