My Samsung smart tv has sound, but no picture. The screen is black. When I turn it on, the power button on tv blinks red a few times and then stops. It is plugged into a DirecTV box. Do I need to change out the HMDI?
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.
·Press the Home (Menu) button on the remote.
Confirm the TV is set to the same source as the external device.
Test the HDMI cable.
Test different external devices.
