I hate giving someone bad news but this model set has a lot of main board issues, there have been many revisions to the original board trying to rectify the issues., you need to match your set to the date code or serial number to get the correct board, the bad news is the main boards can be hard to find and quite costly. A new board should correct the issues you're seeing, we have seen this model with main issues a number of times times in our shop

Going by what you've described, I'd say you have a bad panel and the set isn't fixable however try this before junking the TV, remove the flat ribbon cables, clean then replace them, if that doesn't fix it you can replace the tcon board however I don't think this will help, sorry I don't have better news for you.

If you have replaced the main board and power supply board and are still getting a uniform blue screen on your Samsung LED TV, it could indicate one of the following issues:

1. T-Con Board: The T-Con board, or Timing Control Board, is responsible for managing the flow of video data from the main board to the LCD panel. If the T-Con board is damaged or not functioning properly, it can result in a blue screen.
2. Backlight Inverter: The backlight inverter is responsible for powering the backlight of the TV. If the backlight inverter is not working properly, it can result in a uniform blue screen.
3. LCD Panel: The LCD panel could be damaged or have developed a problem, causing the uniform blue screen.
4. Signal Cable: The cable connecting the main board to the T-Con board or the LCD panel could be damaged, causing a lack of signal and a blue screen.

It's best to consult with a professional repair technician or the manufacturer for further diagnosis and repair. They will be able to determine the exact cause of the issue and recommend the best course of action.

There is a good chance you have a bad panel, put the original boards back in the set, unhook the ribbon cables going to the panel boards from the main or tcon, I didn't pull service info so don't know if this set has a tcon board, in either case, remote the ribbon cables going to the panel boards , if the set comes on with backlights, naturally no picture, the panel is bad

If you've already tried resetting the TV to factory settings and replacing the Power Supply/LED Driver board, the next step would be to check the power cord itself. Here are a few steps you can take to troubleshoot the power cord:

1. Make sure the power cord is securely plugged in: Check that the power cord is plugged in firmly to both the TV and the wall outlet.
2. Check the power outlet: Plug another device into the same outlet to make sure it's not a problem with the outlet itself.
3. Check the power cord for damage: Inspect the power cord for any visible damage, such as frayed or broken wires. If you see any damage, replace the power cord.
4. Check the voltage output: Use a multimeter to check the voltage output of the power cord. The voltage output should match the voltage listed on the TV's specifications.

If the power cord appears to be damaged or not functioning properly, you can try replacing it with a new one. If none of these steps resolve the issue, it may be a problem with the TV's internal components and you should consider contacting Samsung support or a qualified technician for further assistance.

What's the model of your samsung TV? This sounds like a possible panel issue but model will help

Based on the symptoms you described, it sounds like there may be an issue with the main board (motherboard) of your Samsung TV. The fact that you have backlight and the red power button is on, but there is no picture and the TV goes into standby mode with the Samsung logo moving around on the screen, suggests that the main board may be malfunctioning. The specific part number for the main board (motherboard) in your TV model is BN9649639A. You can try to locate and purchase this part online or through a Samsung parts supplier and replace it yourself, but it is important to note that this can be a complex and difficult repair. If you are not comfortable with electronic repairs, it would be best to contact a professional technician or Samsung's customer service for assistance. It's also possible that there is a problem with the T-Con Board. The T-Con board works in conjunction with the main board to control the display of the TV. If the main board is working correctly, and you still have no picture, then it's likely that the T-Con board is defective, and it will need to be replaced. It's also a good idea to check all cables, connectors and check for any loose or damaged parts in the TV, as that could be causing the problem as well. In any case, it is recommended to check the TV's warranty status and the manufacturer's instructions to ensure that the repair or replacement will not void the warranty.

This is either a board issue or bad LED backlights, you can trouble shoot the backlights by unhooking the connector going to the main from power board plug the set in and backilghts will stay on if they're working ok, if you find they're good then I'd lean towards a bad main board, there are several ways to test the main but it would involve using a multi-meter. We've seen a lot of main board issues on this model TV.

Sometimes there is up and down centering but normally it mean that your Aspect Ratio is wrong in Settings. You aren't showing the full picture.

If your TV is still under warranty, you may be able to have it repaired or replaced

One possibility for the sporadic signal loss you're experiencing is the video board. However, this issue could also be caused by a loose cable connection, a tuner issue with the television, or software issues. The intermittent signal loss could have been caused by a loose cable or a damaged connection after the backlights were replaced. I would advise checking each and every cable connection to ensure that they are securely fastened in place and that no damage has occurred prior to replacing the video board. You could also try performing a software reset on the television to see if that helps. The video board may need to be replaced if these steps do not resolve the issue. It's best to talk to an experienced TV repairman about the problem and the best course of action. They will have the experience and tools necessary to correctly identify the issue and suggest the most cost-effective solution.

The issue with your Samsung Solar Remote not syncing with the TV even though the Bluetooth icon is appearing on the TV could be caused by a few different things. Here are some troubleshooting steps you can try to resolve the issue:

1. Check the battery: Make sure that the battery of the remote is charged and inserted correctly.
2. Move the remote closer to the TV: The remote should be within 30 feet of the TV to ensure a strong Bluetooth connection.
3. Turn the TV off and on again: This can help to reset the Bluetooth connection between the remote and the TV.
4. Remove the pairing information: If you have paired the remote with another device before, it may have saved the pairing information and is interfering with the new pairing. Try removing the pairing information from the remote and the TV and then pair them again.
5. Reset the remote: You can reset the remote by removing the battery, then pressing and holding the power button for 10 seconds, and then releasing it. Reinsert the battery and try to sync the remote again.

There could be a few different issues that could be causing the screen to not turn on. It's possible that the power supply board is the culprit, but it could also be a problem with the main board, the Y-sustain board, or the Z-sustain board. Here are a few steps you can take to try and diagnose the issue:

1. Check the connections: Make sure all of the cables connecting the TV to any external devices are securely plugged in. It's also worth checking the power cord and making sure it's properly connected to both the TV and the wall outlet.
2. Look for any visual signs of damage: Check the power supply board, the main board, and the Y-sustain and Z-sustain boards for any signs of physical damage, such as burnt or swollen components.
3. Try a power cycle: Unplug the TV from the power outlet and wait at least 30 seconds before plugging it back in and attempting to turn it on.
4. Test the power supply board: If you have access to a multimeter, you can test the power supply board to see if it's outputting the correct voltages. If you're not comfortable doing this yourself, it's best to bring the TV to a professional for repair.
5. Seek professional repair: If you're not comfortable attempting any repairs yourself, it's best to bring the TV to a professional for diagnosis and repair. They'll be able to troubleshoot the issue and determine the best course of action.

Overall, it's difficult to say for certain what the issue is without further diagnosis. If none of the above steps work, I would recommend seeking professional repair.

Hi Randy, unhook the connector going from the power to main board, plug the TV in and you should see backlights if they're working, this is a nice feature Samsung sets have. If no backlights replace the LED strips, if you get backlights there will be more to troubleshoot to find the issue, however I don't think you will see light

Most likely but look at the part numbers on each board to see if they're the same.
