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 for $124. Part number BN81-01286A A/S T-CON Board.
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 (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.

SOURCE: how hard it is to replace by yourself main board Samsung LN-T4065

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.

SOURCE: Hello, I have a Samsung LN-S4692D.

You cannot test the T-Con bd with a meter. However if you have the luxury of having another same model tv, you can install the bought T-Con bd and see if it is good or bad. Since you said the Menu and channel flashses, then I would replace the Main board.

Samsung tv has vertical lines and washed out appearance why

OMG..why so many bad answers on here all a sudden ...Chances are you have a bad Tcon board or its possible it could be the main as well however tcons fail way more than main boards with your issue, vertical lines means bad tcon, horizontal can mean a bad display...I can count on one hand the times Ive had a bad display with vertical lines and Ive serviced thousands of HD TV's over the years...but what I want you to do 1st is remove the LVDS cable that goes from the main board to the tcon board, clean the contacts and replace it...then do the same to the two flat panel ribbons that go from the tcon board to the panel, its not real common but on occasion they will loose connection and give vertical lines, don't want you to buy a board if cleaning the cable connections will help...just use a little rubbing alcohol to clean them...Good luck, if you need more help feel free to message me back.

Samsung UN46D6400UFXZA Version H302 tv has sound but no picture. Screen lights up initially with some horizontal lines then it just lights up (backlights on) but no picture.

Try removing and replacing the LVDS cable that goes from the main to tcon board along with the flat connectors that go to the panel and see if that helps, if it doesn't chances are you have a bad Tcon board

Replacement tcon board

There is no modification for T'Con boards. If it was a power board, you can do it. You should replace it with the original number.

Samsung flat screen UA22EH5000 tv playing changing station screen blank only light at the back of the screen

Probably the the T con Board is faulty. T con board is the one which drives the pixels. If its faulty then you will not get the picture. the light at the screen shows that its back light is ok. hope you
have sound too. And if you are able to change the channel then is shows that the main board is also ok. But it can on;y confirm by changing the tcon board.
