First of, apologies for not posting in the right section.
I have recently acquired a MAG 254. It works great and its fullyt update with latest firmware.
It works well most of the time but after a few hours ( 2 or 3 hours ), i get a black screen ( black pic and no sound ) and it doesnt matter how many times i change channels.
The only option is to hard reboot which is not very user friendly.
Has this problem been seen before ?
