Re: vertical 1 line

Check voltage supply at vertical amp ic ,if present than change vertical amp ic.Some times supply line is dameged by faulty amp ic.therefore you have to rctify supply and replace ic.Check supply line fusible resistors.

My Dell XPS 9530 has a white vertical line on the display

Fixing this old of a TV would be a waste of money as unless you have the testing gear and expertise you would be guessing. Just buy new and be happy. You could also join a book club and give up watching TV altogether. LOL

Screen picture shrinking . Two wide white horizontal lines

Check vertical output circuits. They control the up and down deflection and when not working you get straight line across front of tube.

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.

Picture adjustment

if your vertical section of your mother board has a vertical adjustment trimmer, adjust it to reach your desired vertical size..if doesn\'t have, increase the resistance of the resisitor only connecting from cold ground to the negative of the e.cap and the positive pin of e.cap connecting to the line 1 of the vertical focusing coil. the common value of the resistor you would focuse is 1ohm, try add with .5 or 1 ohm depending with vertical size result.

Vertical line

Your unit have a problem on a vertical output section.
Parts that are going to check are the ff:
1. Fusible resistor lined in 24v supply at the flyback.
2. Vertical output I.C.
3. Vertical Yoke winding (check for open winding).
4. Vertical out at the jungle I.C.

This is not diy, need to look for a qualified technician to isolate the problem.

Thanks for using fixya...

Ps 27123 have sound, tuning etc only small horizontal color band

Hello bdedrick708,

If what you are trying to say is that you have a 1/4 inch horizontal line across your screen, this means that something in your vertical deflection circuit has failed. This could be the vertical oscillator, the vertical output processor, the vertical coupling capacitor, or the vertical section of the yoke transformer.

If what you are talking about is a vertical line from top to bottom then you are possibly talking about a failed horizontal section of the yoke transformer.

Why so little about the horizontal section of the yoke? That is because if the horizontal section fails completely then you would lose high voltage and no line would be present because you would not have raster (screen light).

In any even check the yoke transformer first. Then work back from there.

I hope this helps,

Thank you,

Emerson EWF2702 TV Problem

Hello yyimerr1,

This is a vertical deflection problem, These are the possible causes:

1) bad vertical coupling capacitor
2) bad vertical output IC
3) bad vertical driver IC
4) bad CRT deflection yoke

Troubleshooting needed:
1) using the TVs schematic locate the driver IC the output IC and the CRT yoke transformer.
2) using an oscilloscope look at the vertical driver signal it should be a sawtooth signal from the driver to the yoke (increasing in amplitude for each section, i. e. driver and output).
3) if no sawtooth patter is seen that is your problem, look for the component in the section where signal is entering but nothing is coming out.
4) replace the components

Now let me tell you something, don't continue to play the TV with the line present with brightness applied, this will burn the image of the line into the phosphorous coating of the CRT.

I hope this helps

Thank you,

T.V. has no picture

I noticed a bright horizonal line about 1/4 in.wide centered in the middle running from side to side. Audio is fine. This just all of a sudden happened it was not gradual. it is due to vertical section failure. please minimise bright to protect crt. solution. solution 1 check supply to vertical section. 2 check for ic failure in vertical section 3 check vertical output section parts. Is it fixable or dumpable?? Please HELP!!!! yes it is fixable it is common problem not major one. good luck.

Samsung ck-5339zb TV

only horizontal line it is a vertical section failure. caution keep brightnenn as low as possible till it is rectified & you put on tv before it this just to avoid screen burn. solution 1 check for loose contact or crack print or loose deflection coil connector. 2 check supply to vertical section. 3 check vertical ic. 4 vertical (50)Hz signalto vertical section. good luck

Vertical line running through video channels 1-4

Interchange the video channels 1-4 and 5-7. Now check white vertical line in video port 5-7. Suppose you get problem remove cable television cable from tv during another two port running. These type problem occurs only when RF disturbance from cable television or video ochannel ports cable wire ground problem. I found there is no problem in tv. External source only the problem. I hope above details give you the better solution.
