SOURCE: LN-T4665F 46 in. LCD- Black Line across screen

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 horizontal thin black line has appeared across screen.


hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

Thin horizontal black line appeared lower half of


Fixed non moving lines usually means you have a problem in the panel display or t-con. If it is in warranty get it to a factory authorized service center. If not you can try to change the t-con and see if this fixes the problem, if not then it will be the panel it's self and will be cost prohibitive to repair.

JVC PD-42DX6BJ plasma 42 inch black horizontal lines over the pic


Here's a link to order the original the JVC upper Y-buffer board and lower Y-buffer board for this model from a major parts distributor if needed:


JVC "PD-42DX6" Replacement Part Upper Y - Buffer Board (LJ41-02760A)

JVC "PD-42DX6" Replacement Part Lower Y - Buffer Board (LJ41-02761A)

Based on the symptoms: It is possible that the Y-buffers are faulty, which may require the replacement of the Y-sus board as well. You may want to get a local technician to diagnose the unit and provide a second opinion.

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.
