Starhub box after long time no use subscribed channels don’t work (22-03-18)

Sometimes u just leave ur starhub box there and you forgot about it for a long time. You bring it out plug it to tv and the channels you subscribed to don’t work. It works on the other boxes but doesn’t work on this. I called 1633. Then the support told me to switch off the box they had to reset something. Then I powered on again. Didn’t work. He told me go to 513 diva channel and press the blue subscribe button. After that there was loading and there was sound already but no display only the loading screen. The support told me to restart and after that it was working
