My Samsung LN-S4692D

Turned on the TV 3 weeks ago, has sound but no picture. replace every cable, and it still doesn't work. Theres no menu or anything. Since it was out of warranty just a couple months over a year, we call a repair man and what was the problem. When he replace the mainboard, still didn't work, and he said it's the main board attach to the panel, which cost around 2 grand. is there any way to fix it? because I do not want to pay which cost to buy a new TV. I will never buy a Samsung TV product again.

Re: My Samsung LN-S4692D

I have a Samsung LN-S4692D that the picture is black but has sound. I can see a faint picture if I shine a flashlight at the side of the screen. Does this sound like a T CON problem or a backlight problem? If it is a backlight problem would you replace the back light inverter (Part# 120V46W2B) or would it be a differet part?

Re: My Samsung LN-S4692D

The T-Con board fixes those sets where the backlights are fine. If replacing the T-Con did not fix your set, it is probably the backlight that is bad. Try checking for a faint picture in a dark room.

Before you give samsung directly, they are very consumer oriented and if it is only a couple months out of warranty you might get them to repair it,, 1 800 samsung

Hi, i have a fairly new samsung 46" tv with sound but no picture

Please check in dark room condition if you can see the light come up in the background of the tv LCD. If you can see light it would be a T-Con board or main board problem. I think those tv had some issues with the T-con board.

Sound but no picture

first guess would be the inverter circuit board. If you decide to replace it your self, please be carefull as there is hight voltage on this part. All connections should be done with the tv disconnected from outlet. Search results for LN S4692D

46" LCD Samsung TV Model# LN-S4692D I have no picture

The back light inverter board may have gone out or it is not getting the 24vdc from the power supply module. Start checking for voltage feeding the inverter board.

No picture just sound. turn tv off and on and then the picture comes on.

Check power supply for swollen capacitor and replace them as needed. Are you getting tv menu?

Rainbow color effect appears when Samsung LCD plays Wii or DVD

Hello, I have a question which video inputs are you using for your DVD and Wii connections? The reason I ask is because this sounds like video distortion cuased by noise. If possible can you send a picture of the screen when it has this problem and send which video ports are being used? If it is noise in the video you may have a saw filter problem, or a decoupling issue. In any event I'll know more once you send those pictures and which inputs you are using for your DVD and Wii. Thank you, Shuttle83

I have a 46" Samsung, model #LN-S4092D. Two weeks ago the picture stopped working. There is sound and some light coming through the rear of the television (when the back cover is off). Sears ordered a new...

If your TV has a 46 inch screen then the model must be LNS4692D not 4092D. I recently had the exact same problem with my LNS4692D after 30 months of use. It was indeed the A/S T CON board that caused the problem. I ordered a board from and replaced it myself. The TV is now working as it should. Saved $500 to $600 by doing the work. I documented the repairs, complete with pictures in a MS Word document but I dont think I can post it here. Replacing the board was not too difficult but it should not be attempted by someone with no experience at all in these matters.
