xerox colorqube 8570 power up ?

[chopper247]

Hi All, new member here... i know this is a quite common fault but if anyone has any more ideas...

basically my printer wont Boot up... there is mains power into the supply electronic module, it on occasion has booted and has been fine.. prints, all was well..
but after shutting it down it now refuses to start...
it is plugged into the same socket as it was when it worked ok ( i know they can be temperamental / sensitive to other equipment )..
this has happened 3 times now.. and it makes no sense...
at the moment it just refuses to start..

any thoughts other than buying a new one would be appreciated...
thanks in advance
