Samsung LN-S4692D 46 in. LCD HDTV - Answered Questions & Fixed issues

First of all stop trying to turn the tv on because you can damage a second board by repeatedly attempting to power the set up after a power supply failure. I have seen it on this model. Usually what happens to this set is the power supply filter capacitors fail. If you were to look at them you would see they are physically bulging. These capacitors are rated at 2200uf/10volts. They can be changed with a higher voltage capacitor to outlast the original components. If you choose to replace the entire power supply more than likely this will happen again in a few years. Anyone who can solder somewhat can replace these parts and repair the problem. A reasonable repair cost for this repair would be between 95-175 at a repair shop. Good luck, Russmann. You're welcome.

Going to need a make and model number to help

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

1. It is not a two years old TV, but a 9 years old one. 2. The common problem of the symptoms is a defective main power supply, you may check to see that are there anny "Pup-Up" electrolytic capacitor on the power supply, if there is any, replace them, you may fix up the TV

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I had the same problem and I replaced the t-con board. My t.v. is fixed!!!! I just couldn't see spending another 700.00 dollars for a repair shop to fix it. The t-con board is located at the top of the t.v. once you remove the back cover. Be very careful removing the two plugs at the top of the board which was easy once I figured out how the clips worked. there is a black lever like connection which flips up, then grip with your fingers the tab and slide the tape like wires straight out. The bottom plug is very simple. Also to expose the t-con board you will have to remove a heat shield cover. Once removed there is foil looking tape that needs to be peeled back to expose the board. The board is very sensitive to static electricity so if you have a grounding strap that you can strap to your wrist and ground to the frame while performing your repair. Its best to lay the t.v. face down on the kitchen table with a blanket to protect the screen. Good luck!

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.

Fighting it out with the manufacturer can be a major problem in cases such as yours. Take many pictures to document the damage and show the failure. Get a local consumer advocate to assist you - many communities have one in their local newspaper or television stations. Last resort, if you are willing to go the distance and are sure you can prove your point, is to lawyer up and go after them for repair/placement cost.

Please check in dark room condition if you can see the light come up in the background of the tv LCD. If you can see light it would be a T-Con board or main board problem. I think those tv had some issues with the T-con board. Search results for ln s4692d

first guess would be the inverter circuit board. If you decide to replace it your self, please be carefull as there is hight voltage on this part. All connections should be done with the tv disconnected from outlet. Search results for LN S4692D

Unfortunately It Sounds Like You Have One Of Two Things Going On.The First Is a Defective T-Con( Timer Control Board ), Which Is An Easy Fix..The Second Is an Intermittent Display Panel, Which Is A Common & Costly Problem..

Most likely T-Con or panel

you have to replace lcd screen . then it will be ok

Need new smps

Most likely need to replace your smps.

Check the power supply to see if you have any bulged capacitors. If so, then you should be able to just replace the capacitors. If not, replace the power supply.

The power cord? Where did it get cut?
