hello, I have several mag 322 all with the latest firmware (2.20.07r2), some of them have a date of manufacture in 2017 and others in 2018 but all boxes have the same issue : horizontal black lines may appear on some channels. It's clearly random (not always the same channel, not after a fixed period of time). Changing the faulty channel and going back on it solves the problem. This problem is less present on 2018 MAG boxes... Boxes that do have a ventilation grid! So is it a problem of overheating? I'm facing this issue with external portals and different IPTV providers. I talked to several other MAG 322 owners about that and they also have this black lines thing...Could you help?
