I see with my oscilloscope, that vertical amplifier( I.C. AN5534 ) oscillate and output signal is not normal.When i measure vertical deflection yoke see about 33 ohms . normal value is about12 to16 ohms.So i disconnect the two parts , measure one by one and i see that one off the parts is not good.
So i change the deflection yoke and solve the problem.
Best wishes ! Nick

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.

No vertical output, but vertical ic workng fine,vertical supply ok,


Touch the input pin of the vertical IC, by the blade of the screwdriver, and see whether there is a tendency to change with width of the horizontal line on screen. If so, check and replace the horizontal, video if, vertical oscillator jungle IC. Check the frequency to the input of the vertical scan IC, with a frequency meter. If there is frequency, and still no vertical scan output, check the yoke connection, and make sure that it has no open circuit.

Tv has horizontal line in middle of screen,sanyo ds25390


hi if only a horizontal line across with no video anymore, you have bad either vertical ic or no dc supply b+( vertical ic ) or no output dc coming from the ic. if it is not totally a horizontal white line and you can see a video you must check leak or bulged capacitors at the vertical section near the vertical ic. hope this can help good luck.

All I get is a narrow bright line across the tv


--- = faulty vertical circuit,could be a defect vert IC.
| = Hor circuit defect,could be a cap in the Hor circuit,mostly around 680n / 250V.

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,

Screen only showing single line of video in center.


hi there, is the single line horizontally or vertically? if horizontal line, you do have a vertical section problem, check some parts at vertical section, the vertical ic, the power source of vertical section ie diode & resistors. ty

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 LG tv has suddenly got a problem with the picture. Whilst watching the tv with no problems at all, the picture was suddenly reduced to a thin vertical line down the centre of the screen and an awful smell seemed to come from the tv There is a short ckt in your tv in horl. section. 1 isolate power from horizontal section. 2 check for normal output from power supply. 3 check parts in horl output section a hor.output transistor b diode & cap in h/output trnsformerckt. c check for print. d if all are ok check for eht transformer. e if every thing becomes then reconnect hor output section supply. f put on the set.

The vertical output IC or the vertical circuit is whats at fault. its all solid state and im sorry to tell ya that its not a user replaceable part. This set is probably not worth the repair it would take to get this set working again but please if you like ask a ;ocal repair shop what they thought about this problem.. Good Luck and please dont forget to rate this thread
