Blaplunkt Sacramento CD33 - problems

ok so in the mornings i've noticed that the display on my head unit will cut out, like i'll still hear music and everything will work, just no display. so, i'm not sure if its just because its been very very cold out that its been doing that or if its something different. because after my car gets warmed up it works fine and doesnt cut out. so if that is the problem how do i fix it?
