Samsung LCD TV turns on and off on it's own
Based on the symptoms you described, it sounds like there may be an issue with either the power supply board or the main board of your Samsung LCD TV. The fact that the TV keeps turning on and off repeatedly on its own, and now it won't start up at all, suggests that there may be a problem with one of these components.
When you unplug the cord connecting the power supply board to the main board, and the TV backlights stay on without turning off, it indicates that the power supply board is working properly. However, when connected to the main board, the backlight turns on and off, which suggests that the issue is with the main board.
It's possible that the main board is malfunctioning and not providing the correct signals to the power supply board, which is causing the backlight to turn on and off. Replacing the power supply board with a new one and still experiencing the same issue, confirms that the problem is not with the power supply board.
It's important to diagnose the problem correctly and not just replace parts without properly testing them, as this can lead to wasted time and money. A proper diagnosis can be made by a technician with a scanner that can read the codes and check the signals of the main board and power supply board.
It's also a good idea to check all cables, connectors, and other electronic parts of the TV, as any damaged or loose parts can cause the problem as well.
It's 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. If the TV is out of warranty, it might be more cost-effective to consider purchasing a new TV, as repairing an older model might not be cost-effective.

Samsung TV, un55nu6900fxza, no pict, have backlight, red on button on, it goes into standby mode with samsung moving around on screen. motherboard bn9649639A any thoughtss
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.

Ln52A550p3fxza samsung tv comes on with loud noise and scrambled screen, any help?
LN52A550P3FXZA TV. The T-con board is responsible for the image processing and video output, and a malfunctioning T-con board can cause a loud noise and a scrambled screen.
Other possible causes could be a faulty mainboard or power supply, damaged or loose cable connections, or a malfunctioning panel.
I recommend attempting the following steps before seeking professional help:
- Check all cable connections to make sure they are securely plugged in and not damaged.
- Unplug the TV for at least 30 seconds and then plug it back in.
- Try a different input source to see if the problem is with the source or the TV.
- Perform a factory reset on the TV by going to the menu and selecting Support > Self Diagnosis > Reset.
- If none of the above steps work, it may be necessary to contact a professional repair service or Samsung customer service for further assistance.

Samsung TV DF400BGLV1H is dead. Looks like a short on LED backlight?
Based on the symptoms you described, it sounds like the problem is likely with the LED backlight strips on your Samsung TV model DF400BGLV1H. When you disconnect the LED connector, the standby voltage comes back, and the T-CON board blue LED lights go on and the boot sound. Also, the fact that the power supply board measures 225 volts on pin 1 and 2 of the D+ on the connector when disconnected and toggles off when connected to the LED, suggest a short on the LED side.
It is possible that one or more of the LED backlight strips may have failed, causing a short and preventing the TV from powering on properly. In this case, replacing the LED backlight strips would be the most likely solution to the problem.
Keep in mind that it is always a good idea to double-check all connections and components for proper function and continuity, before replacing any parts.
It's recommended to seek the help of a professional technician or contact Samsung customer service for further assistance, especially if you are not familiar with TVs. Also, make sure you get the right replacement parts and follow the instructions.

Samsung UN40MU6300FXZC tv would not come on, No standby light.
Hi Walter, I can help you with your TV issues. On Samsung TV's it's normal for the backlights to come on if the connector going to the main is disconnected, on most other makes this isn't the case however. This tells two things, the backlights themselves are working and the hot side of the power board is working plus the inverter, it sounds like you have main board issues, and it will need replacing, it's been the EEPROM that fails on this model, and it has the exact symptom you're seeing. Both parts can be purchased at shopjimmy.com, naturally the IC will be cheaper but replacing it involves advanced soldering skills and the equipment to do it so replacing the board may be your best best

If one half of the screen on a Samsung LED TV goes black and then the other side but one side always works, then it most likely means that there is an issue with the LCD panel or internal hardware of the TV. It is recommended to contact Samsung support and schedule a service appointment to have a technician check the TV for any potential repairs that may need to be done.

Samsung tv keeps turning on and off
The fact that the backlight stayed on when you unplugged the cable running from the power supply board to the main board does suggest that the issue is likely with the power supply board. However, it is still possible that the problem could be caused by a malfunctioning main board or another component of the television.
To confirm the cause of the issue, you may want to try swapping out the power supply board with a known good one to see if this resolves the problem. If the issue persists even with a new power supply board, it is possible that the main board or another component of the television is the cause of the problem.
If you are unable to troubleshoot the issue using the steps above, or if you are not comfortable working with electronic components, it is recommended to seek the assistance of a qualified technician to diagnose and repair the television.
