The only explanation I can think right now is the following:

In[2]:=
$DisplayFunction = Identity;

In[3]:=
Plot[{Sin[x], Sin[2*x], Sin[3*x]}, {x, 0, 2*Pi}]

Out[3]=
Graphics[]

I.e. someone has changed the default setting for $DisplayFunction.

On the contrary,

In[5]:=
$DisplayFunction = Display[$Display, #1] & ;

In[6]:=
Plot[{Sin[x], Sin[2*x], Sin[3*x]}, {x, 0, 2*Pi}]

and the plots are here!

Cheers
Dimitris
