Hello colleagues, I need to know how much impedance the vertical and horizontal deflection coils of a 14-inch TV of the daewoo brand have, its chassis is the CN-001G license plate: dtq-14v8ssfg, the impedances measured in my multimeter are the following of which I HAVE DOUBTS: 1) VERTICAL COIL = 15.2 OHMS 2) HORIZONTAL COIL = 9.2 OHMS will they be correct? you compare a TV in good condition with the same characteristics, thank you very much

Good night, and what is the fault that appears on the TV? Actually the measures of this type do not say much. But they are good readings in broad strokes ...

the solution was A TONTERY really what happened is that the 4 wires were altered almost reaching 4 points and were like "sulfated" from excessive heat and this altered their resistance "OF THE CABLE" because the CORRECT impedances were 15 ohms in the vertical and 4 ohms in the horizontal, but in EL SOCALO I average the altered values because of this cable which I DIDN'T SUSPECT I leave it as an anecdote so that if it happens to other colleagues they don't break their heads, in fact the TV was protected by fault of this "anomaly" this is the real solution and thank you all for your

Hello colleague: what, in fact, we measure in yoke with the voltmeter on the ohm scale is its ohmic resistance ... not its impedance ... given that, if there is a short loop this does not accuse the voltmeter. ..but somehow it gives us an idea of its ohmic value .... the measurement obtained from the 15ohm vertical coils ... may be normal ... but the value obtained from the hor coils, 9.2ohm it is not normal ... in tvs TRC hor coils, usually from 14 "to 21" can walk in 2ohm .... check welds on the wires, go to the yoke and check if there is no coil cut ... measure directly at the yoke terminals .... q, fault has in relation to the yoke ... greetings!

dear nicomena is wrong it is COILS there is not measured its resistance "ohmic" is IMPEDANCE but I already solved it, it was simply nonsense the 4 wires were sulfated by excess heat and changed their resistance value, that if THE CABLE, because the vertical and horizontal coils are pure impedances you can ask another colleague or search the internet, greetings and thanks for your comment

Dear colleague: although it is true that q, are coils and q, when measured with an ohmmeter it can give about 2ohm ... but at the working frequency of about 15625kz the ohmic value of that coil is very different ... on the other hand a ohmetro does not detect if there is a short loop in a yoke ... but for a hor stage. or vertical a short loop is a direct short of the stage ... there are no differences ... this is my humble opinion ... greetings!

The impedance measured in the fields or horizontal winding is out of the ordinary, it gives the impression that one of the fields was open What defect does the TV show?

An open coil does not measure resistance.

When measuring from the connection terminals of the YUGO .....
If only one of the fields is opened, if the impedance would increase, since the fields are generally connected in parallel.
In that sense my opinion goes.
The misunderstanding is for lack of argument on my part

My dear moderator
Two coils or 9.2 ohm fields connected in parallel would be approximately 4.5 ohm.
If one of the windings is opened, only the impedance of one of them would be read.
On that assumption, I base my opinion, since generally the impedance in the horizontal section of the yoke is less than 5 ohm.

Don't explain Javier so much, don't give the ball to the negative votes. The more points you have, the more they will chase you. Read quickly before they delete my post.

Javier Chavez effectively the IMPEDANCE was altered and ignore comments from people who do not know about this saying that what is measured in the coils is "resistance" now the solution was A TONTERY really what happened is that the 4 wires were altered almost reaching 4 points and they were "sulphated" from excessive heat and this altered their resistance "OF THE CABLE" because the CORRECT impedances were 15 ohms in the vertical and 4 ohms in the horizontal, but in EL SOCALO I average the values that I said in my post anyway thank you very much

THE REAL SOLUTION = gentlemen the IMPEDANCE was altered, now the solution was A TONTERY really what happened is that the 4 cables were altered almost reaching the 4 points and were as "sulphated" from excessive heat and this altered their resistance "OF THE CABLE "because the CORRECT impedances were 15 ohms in the vertical and 4 ohms in the horizontal, but in EL SOCALO I measured the altered values because of this cable which I DIDN'T SUSPECT I leave it as an anecdote so that if it happens to other colleagues it doesn't break the head, in fact the TV was protected because of this "anomaly" this is the real solution and thanks to all for their contributions the TV is working perfectly for a long time
