All the electronic equipments revolve around the electrons..
Basically every gadget is made up of tiny transistors, FET etc.. Each of these devices have their own cut-in voltage above which only they will be able to operate... This energy level is the energy at which electrons start to work, ofcourse this energy is released as heat...
The same example holds good for all exothermic chemical reactions as well

Digital devices really don't have any need to warm up, but most are processor based and they do have to load their base software before being ready to interface with the user. Analog devices, like audio amps, do have a tendency to sound better after warming up because the effects of temperature changes have settled out once devices reach their operating temperature.

When you wake up in the morning do you roll out of bed and immediately go for a jog? It takes a few minutes to get yourself together and be able to communicate with the rest of your body.
Same mentality for electrical instruments.

they have to be warm up first because the engin of the electronic instruments once they are in cold mode,it is difficult for them to operate and used by the users....once they have warm up,the engin can operate smoothly.......

To allow for heat expansion, things are designed to work at operating temperatures. Some resistors change resistance because of thermal changes.

Just wait until the vacuum tubes feel nice and toasty OWW!
