Hi all I'm new to all this technology and don't really know much about this box and its workings so please bare with me, I have had this box a while now over three yrs and in the poo set few wks it's been turning it's self off every now and again, but lately if I try to record something or try to look at the menu it just turns off, when I turned it on this morning it turned off every time I used remote, any ideas will be appreciated, regards mal.
