Question about Samsung LN-S4092D 40 in. LCD HDTV

1 Answer

Horizontal multicolored lines appearing

I've owned my Samsung LN-S4092D TV just over a year now and it has started exhibiting multicolored horizontal lines that extend across the entire screen and appear at different points on the screen depending on the input signal. Each line is about a pixel wide.

EX: A 720p input has several of these lines bunched together near the bottom of the screen and several other are bunched toward the middle.

A 1080i input has several more lines than a 720p input signal

An SD signal (cable/ antenna/ DVD) has lines bunched together at the top and bottom of the screen.

These lines appear on every input the TV has. Has anyone experienced this type of problem before?
Thanks

Open up the TV and unplug and re-plug the connectors to the circuit boards. This is most often caused by a poor connection of the circuit board connectors.

SOURCE: Blue/black vertical line in the middle of screen

Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck

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

SOURCE: I have a ln-s3238d that i got a couple years ago.

Hi andrew, its not a big problem.. Decent TV. but the pixels are DEAD. that means you have to recover them by fixing the LCD. this would cost you around £40-60 for a 32 inch TV. hope this helps!

My Samsung LN-S4092D LCD TV is exhibiting a strobing/flickering screen occasionally. I've read that cutting the jumper cable will fix this, but I'm not sure which wire is my jumper. Does Anyone...


It could possibly be a HDMI cable that is bad. If it is hooked up that way, I have found that problem before. Not sure about the jumper cable.

Samsung ln-s4092d no red tint


There are a few things that can cause this. Your t-con board, the signal board or the screen itself. The most likelly and cheapest would be the t-con board. This is the board that transfers your picture from the signal board to your screen. You would have to open up your tv and get the part number from the board itself.

Hi! I was watching my TV - Samsung LN-S4092D - and the picture went to black with a few very light horizontal lines for about 30secs. After that it went to complete black. I thought it might just be that...


Hi Bob. The first Board to cause this problen is the Main bd. The next bd to cause this is the T-Con bd which is mounted on the Panel. Since you saw horizontal lines and that you have text on the screen and are missing audio from the tv means that the Main bd has gone bad. Have a trained Samsung tech service your tv. Call 1-8020-Samsung as they can direct you to a Qualified tech in your area.

Colored vertical lines with sound no picture


im afraid to say that your display has gone the best thing you can do is call the supplyer of the tv if its under warranty or call samsung. the cost of a new display will be 400 - 500 pounds so you may have to buy a new set.
