You can replace it with an aftermarket battery. That takes opening the case and a bunch of fiddling around inside .. If you are good with tools and have a lot of patience then go for it .. look at ifixit.com or iphone4parts.com for the stuff needed .. Otherwise .. Get an external battery case like a mophie or find a local iphone repair place and pay them to do it for you..

Yes your player has gone into a wrong region make sure that if your tv is pal it must be pal NTSC will also make it go black and white check tv input and DVD player settings

First plug a other thing in the plug on the wall if it comes on then you know it's the tv power is a problem it could be that the power supply's has popped also there should be a button on the side of the tv some ware press it in or on make sure there

Go to digihome support to get the Manuel

be sure to check all your input/output connections & cables

3am is the freeview box update time it will do this every day at 3am the loud click you hear you should not hear it but it may be the update switch that turns the tv out of standby for the freeview to be updated its a different switch that turn this on and may be sticking.

is this happened either watching a tv channel or even watching dvd movies?. and then does the display only white screen or a totally black screen?.

If it's a burned DVD or a CD, it might just be incompatible. Not every disc will work in the kind of older drives Digihome uses.

sounds like time for a new unit
