  If there's no picture or video on your Samsung LED TV, check the cable connections by removing and reconnecting all cables connected to the TV and any external devices. Ensure the video outputs of your external devices (like Cable/Sat Box, DVD, Blu-ray players) match the TV's input connections. Verify that all connected devices are powered on and that you've selected the correct input source. You may also want to reboot the connected device by unplugging it and then reconnecting its power cable.

  If your Samsung LED TV won’t turn on, ensure the AC power cord is securely plugged into both the wall outlet and the TV. Verify that the wall outlet is functioning correctly. Try pressing the power button (usually labeled 'P') on the TV itself to rule out a remote control issue. If the TV then turns on, the problem may be with the remote control.

  If your Samsung LED TV turns off unexpectedly, check the Sleep Timer setting and disable it if it's enabled. Also, check if the 'No Signal Power Off' or 'Auto Power Off' features are enabled in the Eco Solution settings and disable them if necessary. 'No Signal Power Off' turns off the TV if no signal is received for a period, and 'Auto Power Off' turns off the TV after four hours of no user input.

  ericagreenSep 1, 2025
  If the color on your Samsung LED TV screen isn't correct, first run a Self Diagnosis Picture Test. If the problem appears during the test, it's likely a TV issue. If not, confirm that the TV's video input jacks are correctly connected to the external device output jacks and that all connections are secure. If possible, test your external video devices by connecting them to another TV.
