This can be an issue with the Timing Control circuit board, but that is just an educated guess.

SOURCE: Several dozen thin horizontal white lines across the top of screen, all channels

These beasts are monsters to get into and service without the proper extenstion cables and a service manual. there are no user replaceable parts inside this set. if you know solid state serviceing, you can try and fix it. There is a bad capacitor or capacitors in the vertical sweep circuit and or the vertical output IC is bad also. If you can solder and unsolder go for it. But if you do not or know how the circuit Works Please find a trained tech to assist you with this repair. Good Luck. PS please do not forget to rate this.

The set is under a year old and is under warranty. The LVDS cable inside these sets have a history of coming loose. The problem could be the panel. Either way, the set is the problem and needs to be looked at. This set is worked on in the home and does not need to be taken to a shop, so, you can still use it. Contact Samsung at: 1-800-SAMSUNG Hope this helps.

SOURCE: Black line running horizontally across TV screen

A line on an LCD, either horizontal or vertical usually means the video driver board is defective or the screen is defective, does it show up as black even on a dark screen? That means a line of LCD "shutter"s is not working and there is a problem that cant be fixed by a reboot or channel change. Bummer.

SOURCE: Samsung HLS 5679W LED DLP TV Horizontal white lines jagged across screen.

What you are sseing is a convergence problem within the light engine of the set. This is not repairable in teh field other than replacing the light engine part. Since this unit is less than one year old, it should be covered under warranty. From the looks of it, one of the LCD panels has shifted internally. Call for warranty service and indicate that the light engine has a problem. With luck, the service company will show up with the part in hand. Replacement should not take more than an hour or so.

Have samsung un55c9000zfxa led tv with horizontal lines across screen can it be fixed?


It's either the control board or the display itself.
You'll have to find a TV repair company. They won't be able to tell you for sure until they test it, and they may charge you to test it. The control board should be a cost effective fix, the display won't be.

Unless you're trained in Electronics, don't open up the unit and try to fix it yourself, there are hazardous voltages even when the TV is unplugged!

My led samsung tv has a horizontal line and the upper right corner shows a white vertical lines


Not good. You may have a tab failure. A repair shop may be able to diagnose and repair this, but most likely the lcd panel is broken. The panel is the most expensive part of flat tv's. A new panel will cost more than a used tv.

Can you please change the input device to some other you know, works? If you do not notice any problem there, look for the aerial cable going close to any power line or has interference from some other transmissions of any kind nearby.
