Does anyone know any common issue with these Samsung LED Smart TVs?
I checked the power board and it seems ok. TV power cycles every few seconds. With bottom HDMI port plugged in, I can see the content for few seconds. Without anything plugged in, just black screen.
Samsung splash screen comes on then Samsung smart tv (4 square logos), after that goes to black screen if nothing plugged in third HDMI port.
I inspected the main board and it seems fine too. Back lights are working.
Anyone had similar problems? Were you able to fix it without replacing anything?
