Question about Samsung LN-T4661F 46 in. LCD HDTV

1 Answer

Lines across screen breaking picture into 4 sections

I get 4 fine lines across the screen when the TV is turned on and only occasionally. It is like the screen is divided into 4 equal parts. The lines are on a horizontal plane and very small, but it really affects the picture. TV is only 15 months old.

    This is exactly what mine does, it usually goes away with in a minute, but if you bump the bottom of the set is will usually clear up. Must be somthing loose on the board and when it heats up it fixes.

    I have the same problem with the same model TV. Below my 4 horizontal lines, a duplicate image is displayed in the background. The problem is a lot worse on the right side of the screen than the left.

Based on reported problems with Samsung LCD tvs, It is probably one of three problems:
Separation of layers of the LCD panel;
A defective LVDS cable connection;
A defective T-Con circuit board.
If light hand pressure on the affected area on the LCD panel changes the problem, its the defective panel. If not, manipulating the LVDS cable will reveal the cable defect. If not, coolant spray applied to the T-Con circuit board should reveal if it is defective by temporarily alleviating the problem. Dont remove the back cover if you dont know how to protect yourself from electrical shock hazards. There can be more than 1000 volts in the backlight inverter area.

It is an indication that you have a problem on the vertical section on the main board. The faulty parts is the electrolytic capacitor which affect the linearity of the screen that's why you encountered that kind of problem.
I've advice you to send it to repair shop or look for a qualified technician to isolate the faulty electrolytic capacitor and do re-soldering for some dry joints on the main board.Once replaced the capacitor your unit will back to normal again.

Black horizontal lines across bottom 1/3 of screen


This is due to vertical section failure. Change the vertical supply rectifier diode and supply filters. Then check zener diode leakage in pumpup circuit section. Also check any electrolytic capacitors leakage in vertical section. If it is old model tv change vertical height, vertical lenearity presets also. I hope given details useful to you.
