It sounds like you may be experiencing issues with the LED lights that you installed in your Samsung 55-inch smart TV. The fact that the dark spot on the screen has moved to the left side and the lights are appearing at the bottom of the screen like Christmas tree lights is not normal behavior and could be caused by a number of factors.
Some potential causes for the issue could include:
Incorrect installation: If the LED lights were not installed correctly, it could cause the issues you are experiencing. Make sure that the lights were installed according to the instructions provided by the manufacturer and the video you watched on YouTube.
Damaged LED lights: The LED lights themselves may be damaged or malfunctioning, causing the issues you are experiencing. Try replacing the LED lights with a new set to see if this fixes the problem.
Other issues with the TV: The issue could also be caused by a problem with the TV itself, such as a malfunctioning display or control board.

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.
