Question about Samsung LN-S4692D 46 in. LCD HDTV

1 Answer

Lns4692d no picture

I have a samsung LCD lns4692d, and the picture no longer comes up on the screen, i can go through multiple sources get sound but no picture. Usually when you change sources there will be a source name on the screen which does not show up anymore. The LCD is backlight, and you can see when you change channels or sources it flashes, but never a picture. Based on other comments I have taken the back panel of the lcd tv, everyone else who had this issues states this to be a issue with tcon (timing controll board) /lcd controller board. Is this the same board where the audio video sources, antennae and cable plug into?

Samsung 46 inch lcd no picture only sound


Could be backlight or the Invertor. While the sound is operating shine a flashlight into the screen and see if you can see the picture or not then let me know and I will assist you. But I will also need the model number of the set.

My samsung LCD LNS4692D has picture for 2 to 5 seconds only after turning it goes out. audio remains on. picture quality is good. is it the T-con?


0ne of 3 has failed:
(in order of probability):

1. Backlight inverter
2. Power Supply
3. Backlight

More specifically on #1 and #2 - capacitors either bulging, leaking, or exploded.

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.

Thanks!

Samsung le40a lcd - picture quality


Hi - I have some suggestions. The following factors effect picture quality:
1. Source (because LCD TVs have much higher picture quality than traditional CRT "Tube" TVs, the worse your source material, the worse it looks on a LCD TV).
DVD and Sky/Digital TV should look excellent on this TV when connected with a good quality Scart lead (nothing too expensive, but a Oxygen Free Copper Gold lead may help) directly into one of the TV's Scart inputs (avoid using "switching" boxes for multiple equipment).
Also, bear in mind that this is a HUGE screen (40 inches I think) and will REALLY show up bad source material.
The best advice I can give is, if you have HD-ready equipment use HDMI connections for everything (ideally with an HD-uplscaling DVD player which will "improve" the quality of standard DVDs on the TV - I recommend models by Philips) and check that you are in "Movie" or "Cinema" mode on the TV.
Make sure that all of your equipment, like your Sky digibox, is set to 16:9 mode (not 4:3) aswell to preserve the true widescreen aspect ratio.
Hope that helps!

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 partstore.com 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.

LNS4692D - TCON Board (seems there is a systemic issue)


You have to be very careful with the flat ribbon cables and be sure not to have an electro static discharge to the board while handling it but it is not that difficult of a repair. It is the board that is located at the top center of the back of the lcd panel. Depending on your problem, eg. line in picture, no picture with backlight.... it unfortunately only fixes about half of the units. The other half need lcd panels which are very expensive. hope this helps.
