I OWN A 55'LED SAMSUNG 7 SERIES MODEL#UN55B7100WFXZA IM HAVING A PROMLEM IM EXPERIENCING POP UP BLACK SCREENS OFTEN ON MY TV IS THIS NORMAL BECAUSE IT IS A LED? IS ONLY A YEAR OLD IS THIS AN ISSUE.

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:

1. 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.
2. 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.
3. 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 troubleshoot the issue, you can try the steps listed above. If you are unable to fix the problem, it is recommended to contact Shop Jimmy or a TV repair technician for further assistance. They will have the necessary tools and expertise to properly diagnose and repair the issue.

what type of tv is it is it led

Inmost of the case,the problem is the LED strips.

To check it, the best way is use a LED tester, if you do not have one, you have to disassembly the LCD panel, unplug the cable between the power supply & the main board, apply the AC power to the TV, you will see the defective strips do not light up.

Are there still capacitor problems with Samsung TVs?

Your electricity may be not stable.

manuly plz pop 5570

You need a 3D source.

You will not have any luck, The Screen only uses RF for control. As far as I know there is no IR receiver on the unit or any RS232!! A nightmare for integrating this product into universal control systems.
