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.

Replacing the capacitors would be a good start. Replace all the ones with the same capacitance and voltage rating even if they do not look bulge.
Let me know if you require further assistance.

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.

Picture went out on 2-year-old Samsung TV model UN50EH5000F. I have sound and full backlight but no video.


You have replaced everything that could have gone wrong - except for the video Screen itself. Check the connections (ribbon) to the screen for oxidation - use eraser to clean.

How to test a Samsung t con board BN81-01286A from Samsung LN-S4692D tv


There is no easy way to test the tcon board. Try switching inputs to determine if you can hear sound from a program. If so, then the tcon board probably is your problem. If you can not hear program audio, you may have a problem with the main board or microprocesser.

LG 42LG30-UD No Picture, backlights work, sound works, control keys work. Everything work, but no video. What could it be?


If you can hear the audio, there should be video too; because, without video, the audio will be muted. I assume something wrong with the LVDS cable. Check it. If you wish to get some details; check the site linked here. Pull up older posts.

I have a Proview LCD TV model # PA-32JK1A. When I plug in the TV, the orange standby light comes on like usual. When I turn on the TV (with the remote or the front panel) the blue power light will come...


Hi, I just read what you have posted on my LCD TV troubleshooting guide, it does not sound like bad T-CON board because you do not get the sound, you disconnected the main T-CON connector from the main board and get the glowing screen but you still do not hae sound.
In the LCD TV, you can discoonect the backlights inverter board power cables (cables from power supply to the backlights inverter board), and the T-CON board cables from the the main board to the T-CON, you should still get the sound since there are no feedback singals from the T-CON or from the backlights inverter boards to tell the main board that they are bad or not.
If you are 100% sure that you do not have sound on all the input modes then I would suspect the main board problem.
At least the backlights ineverter is good.
Do you get the 12v at the T-CON board surface mounted fuse?
