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

I recently bought a 46 in samsung LN-T4665F and have been playing blu-ray movies on it. A thin little black line will flicker horizontally across the screen from the bottom up. It shows up in particular with the screen is blue. I have tried it with different cables (Monstor and RadioShack) and bluray movies. I even exchanged out my bluray player which is also a samsung. It still happens!! It is very annoying to see this thin horizontal black line flicker up my screen...Any ideas?

Re: 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.

It sounds like your LCD panel TFT (Thin Film Transistors, each panel has millions of the transistor) driving circuits are failing, it will get worst with more lines appearing. New panel will be needed.

I have a surface crack in my panasonic 60 in lcd tv. Model #pt60lc14. Where can I find a replacement?

Im afraid to tell you there really isn't a replacement for a cracked screen. LCD's don't have thin film over them like old projector big screens.

Unplug for 30 seconds from it's power source and then try it again. If that doesn't work, call Samsung for further troubleshooting and have your model number and serial number handy. Please be prepared to tell them how long the line is.
