Question about Samsung Televison & Video
How to fix horizontal lines across top of samsung 46" led tv, model UN46D6900WF.
This can be an issue with the Timing Control circuit board, but that is just an educated guess.

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.

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.

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.

after changing the lamp, I still had the same problem as you. I contacted sony and they offered me a brand new 40 inch bravia flat screen tv replacement...at no cost! If I chose a 46" or 55" there would be a charge between $325
