My Openbox S9 after many years of use is just blinking on and off with the red dot. I was thinking of replacing it with a low cost HD-S2 unit but my son thinks I should get a 4K dvb with blind scan, (we don't even have a 4K TV). I was looking and saw Zgemma H7 UHD wondering if anyone has tested it, or some other 4K type that has blind scan? I was just going to buy a Amiko HD.265 and not have to buy a new TV as well. On a side note I'm burning oil for the fist time in years.
