Problem with TV HAIER 21

The problem is that this 21-inch Haier TV was on and for now the screen was closed and left a narrow bright line in the center of the screen from top to bottom. I would like someone to help me identify the problem, I think it is horizontal. Regards....

Hi. The fault is horizontal. Review welds on that circuit well. Coils, resistors and diodes. Everything. If the components are not fashionable one by one. if you have any doubt, remove it and measure it. Check print that is not cut check welds in the yoke collection sheet.

What chassis is it?
Always in your question provide that information, so you will have better advice.

This is the number that appears on the label 400H46B60558

In the chassis look for the number. Or take a picture of the numberings you have.
Another thing you can do is see what regulator it has in source, micro, jungle, vertical, audio IC. And capable with that data is chassis.

Friend uploaded two photos of the plate, indeed when reviewing there was a damaged resistance, which is very difficult to interpret the color code to know how much it is, that is why I attached a photo of it in addition to another marking the position where it was If you could help me identify it I would appreciate it, the other is that a coil very close to this resistance when measuring continuity does not give any value, I don't know if it will be normal. It is also marked in one of the images. regards

Hi. It's half weird that coil is cut. Maybe it is desoldered right where one of the 2 pins is attached to the copper wire that are the coil terminals. You must remove it and see well.
On the plate it tells you the location of that R (resistance), which I think is of a low ohmic value. The diagram is fundamental.

Maybe it's the R 441 that goes parallel with that coil.
1k value 1/2 w. I repeat this diagram is necessary.

ok I'll see later if I find the diagram, because right now I don't have the chassis type here, I took a picture but I don't have it here, anyway thank you very much ...

Look carefully for the chassis N * on the board. On both sides. Here you will find a diagram that I don't know if it's the same but it can help you a lot.
