Can anybody tell me why my mag 254 will go to black screen all of a sudden . Seems to be after I have it on the same channel for a while . There is no set time but when it does , I just push the home button and change the channel and when it kicks in go back to the channel I was on and then it works fine . Don't know if there is an non activity time on this unit or not . Same thing when it starts freezing . Just change the channel and then back and usually it is ok . Otherwise I think it is a pretty good unit for the price .
