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.

About 99% of the boards from shipjimmy are good, unfortunately lI think you have a bad panel and its destroying the tcon board, did you check the fuse on the tcon board?

Hi there, my Samsung TV turns on, but the screen is black and the audio works. I changed the main board and power supply/LED board. I'm thinking the T-con board but I just wanted your opinion.


Maegan,
You have already changed power supply/led board and main board. What is left now is the tcon and scaler board. Please try tcon.This may solve your problem. By the way, there is a systematic way of singling out the faulty board. A little research on this will save you save you time and money. Good luck.

The backlights aren't working on my Samsung UN32ES6500FXZA TV. I performed the flashlight test and can see a picture and the audio works. Can you please let me know what part needs to be replaced?


You have at least one shorted LED in the panel, reason it works with the main disconnected is your removing shutdown circuitry, don't run it this way for any longer than necessary when looking for the faulty lamps..Also be really gentle with the panel and flat cables going to the TCON board, they can be damaged quite easily and if that happens the set is junk..good luck!!

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.
