Have changed all boards except the T-Con board. No change
My problem began the same way, then the tv turned off everytime I tried to turn it on. First I opened the tv, made a list of all the electrolithyc caps values and temps in the power board and gone to the store and bought all except the bigger one (like USD 8) changed all the caps and then the tv didnt turn off again but image was all white.
Then searching in youtube found about the t-con board issues but the entire card was too expensive to dump so searched how to repair the t-con and found I can change the main chip so bought 2 in ebay from china took like one month but was just USD 8, so carefully cut all the old chip legs, retired the chip, used a soldering iron to retire the old legs, cleaned, put bits of new solder in the tracks, placed the new chip and began to paste leg by leg, tested continuity and checked for solder bridges between legs, assembled, turned on the tv and half screen has strips bot the left side was ok so rechecked flex cables between t-con and lcd and found bent tracks, carefully repositiones, assembled and now my mom has a brand new samsung 32in LCD to watch CSI and stuff... Sooo F_ck u Samsung LOL
Hope you can repair yours, every problem is a world so may not work for you but for USD 8 in chips, patience and some pulse soldering i think it worth the try.

No it is the little board underneath the metal container at the top middle of the panel..the very top.

SOURCE: sound no picture, which component is tcon board? where all audio/video/cable/hdmi plug in to?
I have LNS4692D. Returned from vacation, turned tv on - no picture. Tried turning tv off for 4 hours- nothing. Symptoms are: tv is on - no picture , just sound; menu doesn't show, volume bar doesn't show;E.Saving is working - the backlight is changing from lighter to darker.
Found this website and ordered T-con, otherwise known as the LCD panel driver board, p/n# Bn8101286a ( thanks premtech) from partstore.com for $124. Part number BN81-01286A A/S T-CON Board.
Installation:
1.Remove plastic cover. There is an arrow for each screw that needs to be removed. Make sure to unscrew pins next to VGA port. I've spent some time trying to figure out what else is holding the plastic panel until I found this pins.
2. Remove big metal shield in the middle of tv that is covering main components. This shield is being held by small black screws all around it.
At this point you will see cover of T-CON. Here is the picture
http://www.avsforum.com/avs-vb/attachment.php?attachmentid=118863&d=1220531321 (thanks ldac9). Do not attempt to remove that cover yet. Proceed with a next step
3.Remove metal panel that holds main components. Locate big chrome screws that have arrows pointing to them and unscrew them. Remove 2 more screws on the bottom of the panel that holds it together with a box for cables. At this point the main panel will be lose
4. Carefully start lifting the panel. You will see that there are connectors going from components on the panel to components on the lower panel and T-CON. Carefully unplug these components and raise the main panel.
5. Remove 4 screws that holds T-CON cover. Pull the cover so that T-CON is completely exposed. The cover is connected by thin alluminum , don't hesitate to pull it , but don't rip it out.
6. Once T-CON is exposed you will see 2 red ribbons. I've spent some time to figure out how unplug those from old T-CON board. Here is the suggestion. Don't try to pull it out. All you need to do is to lift small plastic lever that is part of a connector. Then ribbon can be slided out. If not sure what to do, see how this is done on the new T-CON. It has a principle of buckle on airplain safety belts.
7. Remove old T-CON and install new you.
8. Follow reverse order.
I've never fixed TV before , but this was totally successful project.

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.

Hello rdblum, Dave here! I can tell you that you most likely have a bad T-con board also known as a Timing control board! P/N:3240WTC4LV0.5 (((( Please make sure this is the same part # you have on your T-con board before you buy a replacement board!)))) If you replace this board it will most likely fix your TV buddy!
Just to give you heads up! There is a 10% or less chance that the LCD PANEL it's self is bad! I my self have only come across this type of problem where the panel is bad once in the past two years! I have also done this repair at least 14 times in the last two years on an LN-S4051DX & LN-S4041DX!
Please feel free to call or message me if you have any other questions! All others are also welcome to call or message me if you need help with you LCD or PLASMA type TV!
Thank you! :-)
