Only Horizontal line

When the TV is not warm, there is only an horizontal line on the screen. It's like all the screen is compressed into one line. The rest is dark. When the TV gets warmer and you hit it on the right side, screen strech and everything is OK.

If you can hit it, it is probabl;y just bad solder joints on the vertilcal output IC (yes thats right vertical, because it stretches,or in your case compresses the picture vertically). kind of hard to point you to it if you've never been in a tv but it will be a little chip standing up mounted onto a piece of metal (heat sinc). There will be a few though the IC will likely have 1 row of pins maybe 7-10. And probably have a part number on it that begins with "LA" like maybe LA7838. You can tap around the different heat syncs with a NON-METALIC with the TV on until you find the one that is sensitive that should help you identify the vertical IC. Any way unplu flip the PCB over and resolder that IC. That should take care of it.

SAMSUNG - UE40F6670 LED TV - I have thin black horizontal lines appearing in upper half of screen. They get lighter as the TV warms up but don't go away.

IMPORTANT: Horizontal lines on the screen are virtually NEVER caused by a bad T-con board. Horizontal lines indicate a defective LCD panel (screen). Check ribbon connectors coming from screen and the T-con board first but likely the Panel.

Black screen with bright horizontal line through center

Your vertical IC may need resolder. You may have a bad capacitor or two that created an extra warm IC and create bad grounds. So resolder and check those caps near and around your vertical IC. If you continue to see this horizontal line you may have to replace the vertical IC. And you may as well check all grounds as well. Good Luck and be careful!

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,

Toshiba TV CX2789K Horizontal Line

Failure in the vertical deflection amplifier section. This is usualy from failed components, and sometimes cold solder connections. Most of the time, I found bad capacitors, and sometimes the output IC or transistors (depending on the model type) that have failed.

Take the set to a service center for an estimate. You may find it more feasible to buy a new set depending on the parts that failed and the time involved to do the work.
