Better to state what model of box and the firmware you have on it, this info will be required if any help is forthcoming, at the moment it is a bit of generalisation question.
So it is a Eurovox Max V 2008 black, the symptoms seem to suggest a possible hardware fault is developing, C14 cap (Check Link) or a faulty power board, can't be any more definitive than that. (you could first try a reflash with same firmware see if it helps any) http://forums.afterdawn.com/thread_view.cfm/714731 http://forums.afterdawn.com/thread_view.cfm/562687 Best of luck.
Thanks for the help Mal i've turned it off for a day and it seems to have fixed it for the moment another quick question i've ordered a box from one of the ads site sat4u i think it's the newer version that can be used with usb was that a good idea
I presume you are talking about the Starview 4 The Box Super USB, if so you will find a couple of help files in Eamo's FTA Library at the bottom of post. Don't have any knowledge/dealings of that site, if you are getting one of those boxes don't forget to get a USB stick that is what you use to load the firmware and logo which you will also find in Eamo's.
This was happening to a friend of mine The problem turned out to be, he had the vents covered We all need air.
It has to be turned off more now the vents are free but i think u have a point with it over heating never use to turn it off when i turn it off for a while it comes back tnx for the advice
