Samsung led tv`s screen blink on some freeview channels
Can anyone shed any light on something i`m baffled by. I recently purchased the Samsung 32 inch UE32D5520 led tv. On some freeview channels running on multiplex c, pick tv (11) and pick tv+1 (44) as an example, the screen blinks black after 30 seconds. After this blink if you press the guide you should see a mini screen of whats on, but it`s just black. If you then turn the guide off, the screen stays black for nearly a minute before showing whats on again. I changed the set twice and still the same. The model in the showroom also did the same. I now have the U32D6530 model which also does the same. Anyone else ever noticed this happen, or have an explanation?
