SOURCE: Picture gone from TV Model LE46M51B

I suspect that your backlight has gone out. If you shine a light on the screen can you see remnants of the picture that should be displaying? If so, it's definitely the backlight, and most likely the power inverter for the backlight. You can probably find a replacement inverter, but you may need a repair manual to install it. I'd recommend checking the warranty status first and sending it in for repair if you can.

SOURCE: LCD TV SCREEN PROBLEM RED HORIZONTAL LINES OF DOTS ALL OVER SCREEN PLEASE HELP

I unplugged the TV and now the picture is back.I read that the LCD's are vunerable to static build up so unless my daughter is using her TV I unplug it.

I was thinking about getting a large LCD for the family room but I'm not going to until they improve on this technology.

Good luck to everyone!.

Cheers.

Hi,
It seems just channel stored data issue.
Please perform Auto Preset / Auto Channel / Auto Tuning (mentioned menu items) and store all channels again.
Hope problem will resolve.

SOURCE: how hard it is to replace by yourself main board Samsung LN-T4065

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

Samsung LED TV has dark area on top


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Channel displaying on Samsung 32"LCD TV


Most remote controls have a "display" button. Pressing that is what gets that channel number on the screen. Try pressing it again and the display should turn off. On some brands the display may cycle through various combinations (channel number only, channell and time, etc.) before it goes away, so it may take more than one press of the button.
