Try all repairs and troubleshooting at your own risk.
In this video we will show how to replace the Samsung LED strips that we have listed on the screen. Be sure to match the important information on our product page, when replacing LED strips to be sure the replacement strips are compatible with the originals.
When replacing LED strips, you will have to remove the panel.
Removing the panel can be very difficult. If your TV panel is damaged during the replacement process, you will have to get a replacement TV.
We will start by removing both pieces of the back cover off the TV.
Remove the cover over the T-con board.
Use tape to hold the speakers in place.
Disconnect the key controller and secure it to the chassis with some tape.
Flip the TV over and using a five in one tool or a putty knife or something similar disconnect the bezel from the chassis.
Disconnect the buffer boards from the t-con.
Release the buffer boards from the tabs that secure it. be very careful as this board is very fragile.
Using painters tape or something similar, tape the buffer board to the panel.
Removing the panel is very important. But you must be sure the panel does not flex or bend. If the panel cracks or breaks, you will need to replace your entire TV.
We recommend using a suction cup to lift and remove the panel, but you could also use some thin sheets of plastic or something similar to lift it away.
Using a five in one tool, or putty knife or something similar, pry the panel frame from the chassis.
Separate and lift away the layers of diffusion. You can tape them in the corner to keep them together and in order.
There are some clips that hold the reflector sheet to the panel. They can be released on the board side of the chassis and then pulled out from the panel side. Be sure to look underneath the boards if you cannot locate all of the clips.
Remove the reflector sheet from the chassis. The reflector sheet may be sticky on the backside that is attached to the chassis. Be very careful when removing the sheet, so you do not tear it.
There is a little bit of tape holding these original strips to the chassis. Remove the strips of tape and disconnect the LED strips from the cable, before removing them.
Install the replacement LED strips. To help hold the replacement strips in place, we are using some double sided tape.
Align the strips into position and then connect them to the wire.
Align the reflector sheet on the chassis and reinstall the clips.
Install the layers of diffusion.
Reinstall the frame.
Lift the panel back into position and be sure the corners align correctly.
Release the buffer board and lock it back into position.
Reconnect the buffer boards to the t-con.
Reinstall the bezel and be sure it is properly aligned.
Reinstall the keypad controller.
Reinstall the t-con board cover.
Reinstall both of the back covers.
PLEASE NOTE: The models shown may use various different sets of LED Strips. Please match the original strips in your TV to those in the photo before ordering. 29074A or 29075A can usually be found printed on the small barcode stickers on the strips.

LCD & LED TV Repair - No Picture No Image & Blank Black Screen Flashlight Test - Fix LCD & LED TVs
LED & LCD TV How to Diagnose Symptom of No Image on the Screen
CLICK HERE to BUY TV REPAIR PARTS:
Tutorial for Samsung TV No Image on Screen
Tutorial for Vizio TV No Image on Screen
Tutorial for Sony TV No Image on Screen
This flashlight test will show how to identify if you have any video appearing on the screen and whether or not you have backlights. Within this test, we will show how to determine if the problem is a bad t-con board, bad main board or bad backlight inverters for LCD TVs or LED driver for LED TVs.
Most LCD TVs are made up of a main board, a t-con board, power supply board and backlight inverters. Some TVs have one backlight inverter, some TVs have two backlight inverters and some have the backlight inverter built into the power supply board.
Most LED TVs will have a t-con board, a power supply board, a main board and an LED Driver board. Some LED TVs will have the LED driver board built into the power supply board.
If you have no picture on your screen, the first thing we will want to look at is to see if we have backlights or not. You can do this in a few different ways. The first is by looking through the back of your TV and seeing if you can see white lights shinning through holes on the panel.
You can do this a few different ways. The first is by looking through the vent holes on the back cover of your TV and seeing if you can see white lights shinning through the holes on the panel. Be sure to turn off all the lights in the room. As you can see on the screen, we can see the backlight is on through the top vent on the TV.
If it is too difficult to notice if your backlights are on or not, with the back cover still on, you will need to remove the back cover of your TV and look for the light shining through the panel.
Here is what the chassis looks like with the back cover removed and the backlights working. Once you have determined if you have backlights or not, you can then move on to the next steps.
If your backlights are working, but you have no image on the screen, that means the problem is either the t-con board or the main board. Next, you will want to see if you can hear audio. If you cannot hear audio, try and remember if you had audio immediately after the TV image went away on the screen the original time. Or you can also cycle through the inputs to see if you can hear any audio on any of the inputs. For example you could connect your cable box to your TV and try to find the input for that cable box knowing that it would be sending audio to the TV.
If you do have audio and you do have backlights, I recommend starting by replacing the t-con board as that will be the fix, the majority of the time. If you definitely have no audio and you do have backlights, then the problem could either be the t-con board or the main board. You will need to replace each board individually to see which one fixes the problem.
If you do not have backlights, you will want to turn all of the lights off in the room and get a flashlight. Apply power to your TV and press the menu button on your remote to pull up the menu on the screen. You will not be able to see the menu until you shine a flashlight on the screen.
You may need to twist the flashlight and try different angles to be able to see the menu. As you can see on our screen, the menu shows up and you can even read the AV1 on the screen.
This shows that the TV has no backlights, but the image is showing up on the screen, thus our inverter and LED driver is bad and our T-con and main board are good.
You can see on our screen that I can turn the menu on and off and the image appears and then disappears. At this point you will want to replace the inverter or LED driver or the power supply if it has the inverter or LED driver on it.
So as a brief overview, if your TV does have backlights and has audio, I recommend replacing the t-con board first. If your TV does have backlights but does not have audio, then it is either a bad t-con board or main board, and each board will need to be replaced individually to see which one fixes the problem. If you don't have backlights, but you see an image on the screen with the flashlight, that means that your main board and t-con board are good and that you will need to replace the backlight inverter or backlight inverters on your LCD TV and the LED Driver on your LED TV.

Samsung LCD TV Repair - How to Remove & Install Backlight Inverter/Power Supply Board (LIPS) Board
How to properly remove the LIPS board for BN44-00264A, BN44-00264B, & BN44-00264C
CLICK HERE for Replacement Parts:
In this video we will show how to properly remove this board from the panel for replacement or repair. This board is a combination of both the backlight inverter and the power supply and can be referred to as a LIPS board.
It is very important to be careful when removing this board from the panel. You will want to be sure that you do not remove or damage this black strip on the panel which connects directly to the lamps underneath.
I will begin by disconnecting this cable from the LIPS board. Next, using a screwdriver I will remove all of the screws that secure the board to the panel. Be sure to save the screws as you will use them again when re-attaching the board.
After I have removed the screws, I will pull the board free from the panel. The board is secured in place by tabs that are inserted into the black strip. In order to safely remove the board, I will put my hands on both sides of the board and slowly and gently begin pulling back while rocking the board back and forth until I have pulled it free.
Be sure to not use too much pressure and always be sure all of the tabs have been removed from the black strip before lifting up on the board.
Now, I am ready to re-install my repaired or replacement board back into the TV. Again, I will put my hands on either side of the board and line up the tabs. Then, I will slowly and gently begin applying pressure while pushing the board back into place in the black strip.
Next, I will reinstall all of my screws to secure my board to the panel. After the screws are installed, I will re-attach the cable and put the back cover on the TV.

Samsung LCD TV Repair - TV Won't Turn On - How to Replace Power Supply & Main Board
Samsung TV Repair How to troubleshoot standby problem
Click Here for LCD TV REPAIR PARTS:
Click Here to Buy an ESD Wristband!
This video is designed to be a guide for testing and troubleshooting your TV repair. Please note that other complications may exist that aren't addressed in this guide. While we always strive to provide accurate and detailed information, we can't guarantee that it will fix your TV's issues.
So in this video today we are going to be looking at a Samsung LCD and how to diagnose if you have a bad main or a bad power supply. This particular power supply is the BN44-00197A and this is a high voltage power supply. So it has these two high voltage leads that go out to the inverters and it has a couple of connections that go to the main board. If your power supply looks different, we are going to take a look at how to check those power supplys too, but it will be a little bit different from this one.
So this video is for if you have no standby, or if you have standby and the TV will not power on and also if you have no backlights. It kind of covers a lot with this one. So in order to find out where the problem lies, we are going to go ahead and disconnect the main board by undoing the two cables from the power supply. We are then going to use some jumpers to force the power supply and the backlights to turn on and then we will know that if the backlights come on and the voltages are all present that the power supply is good.
Now in this case, I have just got some jumper wire and you can also use resistors, sometimes it is a little bit safer to put a resistor in there, but straight wire will work too.
You can see here we have got a little diagram showing the pinouts for the connector. You can see that pin 1 is going to be the power on off and down to pin 3 is our 5 volt standby and those are the two pins that we have to jumper. On these connectors, because they are double row pins they mark pin 1 that little triangle right there and on these it goes pin 1, pin 2, 3, 4, and it goes back and forth. So we know that pin 1 is going to the first pin and pin 3 is going to be the next pin over from it.
Go ahead and follow that brown wire down and that's going to be on this side and we can take our jumper wire and put it into the first hole and the one right next to it, pins 1 and 3. The nice thing is that if you have the insulated wire, you don't really care if it falls over and where it lands because it won't short out. If you have bare wire, be careful that it does not touch the metal chassis, because otherwise it could short out which could be bad.
On the second connector you see its got the 5 volt detect line and inverter on off, that's pins 1 and 5. Then its going to be the 2 outside pins. Jumper it like so and then again we have insulated cable so we don't care about where it lands. Now we can go ahead and plug in power and see what happens. So if your backlights are working correctly, you are going to see the white lights shining through the holes in the back of the TV. This light should turn on pretty much immediately, there shouldn't be any real delay. As soon as you apply power, you should see this white light shining through. If you see that, that means your backlights are good. With those jumpers in, it should stay on permanently. If you had problems with your backlights failing after a few minutes you could put the jumpers in and run it and then see if the light stays on. If it does, then you know that the power and backlight inverters are good and that you actually have a main board issue.
This is also a good chance to take your meter and just check that the other voltages on the power supply are correct and present. So I have got it set to DC and we will just use the chassis for a ground, usually I just find an empty screw hole and drop the negative probe in there. Now we can go through and we can probe the connections. This is standby, which we know we have, there's the terminal voltage and we can go down here and check for our voltages. So we have got a 12.4 volts which is close enough. It should be 13, but half a volt is pretty normal. You can just go through and compare and make sure that they are all present and correct. If they are all good, then you know for sure you have got a main board issue and you can go ahead and replace the main.

Samsung TV With No Image & Blank Screen & Has Backlights - Samsung LCD TV Troubleshooting Help
Basic tutorial showing how to troubleshoot Samsung LCD with Blank Screen & Has Backlights
Here we have a thirty two inch Samsung LCD TV. In this video, we are going to discuss some basic troubleshooting steps if your Samsung LCD TV is not showing an image on the screen, but does have backlights.
In most Samsung LCD TVs, we have four boards. We have the main board, the power supply board, the backlight inverter. The backlight inverter can sometimes be covered by a plastic or metal shield. We also have the T-con board, the T-con board can also sometimes be covered by a shield. Click the link in the video for more information on the basic functions of these boards.
If you have no image on the screen of your Samsung LCD TV, you will want to first, run the flashlight test to see if your TV has backlights and an image on the screen, when pointing the flashlight at the screen. Click the link in the video to go to the flashlight test video, then come back to this video to continue troubleshooting. After running the flashlight test, you have now been able to determine if your TV has backlights or not and if your TV has an image on the screen while using a flashlight.
If your TV does have backlights, but no image on the screen, continue watching this video for troubleshooting help.
The first thing you will want to do is check the t-con board and the main board, and give them a visual inspection looking for any burnt or damaged components.
Here are some examples of what a puffy capacitor or burnt or damaged component will look like. If you have any damaged components that look this way, you should replace the board. If there is not a replacement board available, you can also try replacing the individual components or purchasing a repair kit. Removing and installing new components requires the ability to be able to solder.
When looking for damaged components or burn marks, you can also look at the bottom side of the board. You would simply, just need to disconnect all of the cables and then remove the screws that hold the board to the panel.
Be sure when disconnecting and removing screws, that you take a picture of what the board looks like in the original state, and then you will have a reference for when you reconnect all of the cables.
If you do not find any damaged or burnt components, then you can also check the LVDS cable to be sure that it is seated properly and that there is no damage visible on it.
Here is an example of what an LVDS cable looks like. If you do see visible damage to the LVDS cable, you can search your TV model number on our website to try and find a replacement.
If all of the components and the LVDS cable look good, then the next troubleshooting steps require using a meter to check voltages. If you are not able to check voltages, then the problem could either be with the main board, the t-con board or the TV panel. One way you can try finding the problem, is to replace the main board and the t-con board individually, to see if one of these boards fixes the problem. This would require you to purchase both boards and then see which one fixes the problem or purchase them individually and see which one fixes the problem.
If you are going to purchase multiple boards and replace them individually, before purchasing be sure to understand the return policy of the company you are purchasing from, as there may be restocking fees or parts that are not returnable.

How To Fix Samsung LCD TV - Samsung TV Repair (Blank Screen)
This video will take the Honest out of Samsung. This is a how to video showing you how to fix a Samsung LN-4692D LCD HDTV. This video demonstrates how to remove back panel of display, remove faulty t-conn card and replace with a new t-conn card.
This High Definition Television went black less than 2 years after purchase ($3,500). Samsung would not back their product and so it hung on our as decoration for nearly 2 years.
At the time a repair was generally quoted at between $600 - $1000. Naturally I wasn't going to do that. So 2 years later and tens of thousands of pissed off customers later, a fix has been found in the form of a $100 T-Conn card (BN81-01286A).
Please take the time to watch this How-To on repairing your Television!
Get the most from your broken LED TV | make your light box
If you are a conservator-restorer who have unused broken LED TV panal, this video is for you.
It is a bad moment If your screen is cracked, there is no way to repair the existing TV screen, you would have to replace the TV panel. In addition, these TV panels can also sometimes be very expensive and can cost up to 80% of the price you paid for the TV originally.
However, the good news is, you could repurpose broken led TV and make it useful to be used in paper conservation 😉
