Screen going black and flashing Samsung QLED

We have a Samsung QLED 75" Smart 4k Model QN75Q7FAMF which we purchased in December 2017.

We recently began to have problems with the screen suddenly going black while we are watching TV. The screen will flash Samsung QLED. Sometimes it will go off for a few seconds and sometimes it could be serveral hours. We rebout the cable system and sometimes that works and sometimes it does not. 

Geek Squad has been out to fix it several times but has been unable to fix it. We have had our cable checked multiple times and that is not the problem. It appears to be an issue with the TV.  I have heard that these Samsumg TV's have this issues due to the processor that goes between the TV and the cable box. Has anyone had the same experience? Any advice?

When your TV has a black screen even when it's on, it's quite possible it could actually be your external device and not your TV. If your TV is connected using a One Connect Box, there are a couple of extra steps to troubleshoot.

 

  1. Tv without the one connect box has no picture

·Press the Home (Menu) button on the remote.

  • If the menu appears, the TV is powered on but is either not on the correct source or not receiving a signal.
  • If the menu does not appear, the TV may be having power issues. 

Confirm the TV is set to the same source as the external device.

  • For instance, if your cable box is connected to HDMI 1, set the TV source to HDMI 1.
  • If the TV is set to the correct source, but there is still no image, unplug and reconnect the AV connections one cable at a time, from both ends of each cable. If there's any damage to the cable, it will need to be replaced.

Test the HDMI cable.

  • To perform the test, make sure the TV's source is still on the HDMI setting for the cable you want to test, and then navigate to Settings > Support > Self Diagnosis > Signal Information > HDMI Cable Test > Start Test.

Test different external devices.

  • The final thing to rule out is the external device you're using. Try connecting a different device, or using a different source port. If you were unable to test the cable in the previous step, then try swapping the cable, too.
  • If the TV can display a picture in any other setup, then you've ruled the TV out as the cause of the issue. Keep trying various setups until you identify the device or cable that is not working, and troubleshoot or replace it.

If there is still no picture, use the following link to find a list of service centers near that can do the in/out of warranty repair. http://www.samsung.com/us/support/service/location
