happened three or 4 times so far. i was getting frustrated over the positions of the diseqc1.2 so went to factory default and started programing it again. this is an az premium plus. i did get the video thanks to the setup info to change pal to ntsc. when i am not using the box i put it into sleep mode. a few times when i boot it up now, li have no video and have to go through the pal to ntsc sequence. i did have a usb flash drive in the unit so removed that this morning. that might have been the problem but i didn't have any firmware on the flash drive. btw, i had to change to the azbox because my openbox s9 was stuck on the 'on' display. powersupply problem again. openbox s9 is so much easier to operate than the azbox. hope the microhd is easier to operate than the azbox. charlie
