Hello! Thank you so much for posting about this. I completely understand your concerns with the TV having a black screen after 20 or 30 seconds. I'll be more than delighted to assist you with this issue. If able, press the menu button on the remote. If the menu does not appear, the TV may be having.
If you haven't already, you want to 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. Navigate to Settings, and then select Support. Select Device Care, select Self Diagnosis, and then select Signal Information. Select HDMI Cable Test, and then select Start Test.
If the test says the cable is bad, replace the cable
If this does not help I recommend letting a service technician have a look. As we would like to gather additional information and look at this from a case-by-case basis, please provide the full model code and serial number of the device as well as your best contact phone number, name, and email.
