Of course, there are risks to doing anything. A risk to never unplugging 
anything is lightning damage.

In the past, full power cycling got a bad rap for several reasons.

1. Remote controls do not work.
2. The unit fully cools off. This makes the off to on temperature swing 
larger.
3. Large temperature swings have been associated with cold solder joints 
releasing and good solder joints becoming cracked. Most everything these days 
is put together with solder, so this risk still remains.

HOWEVER, it is my opinion that the quality of automated soldering has vastly 
improved over the last 25 years when these 'old wives tales' originated. I 
don't think it's anywhere near the problem that it used to be, both based on 
what I read and what I have experienced, so I'd say that the risk of damage 
from completely removing power during down time for a great majority of all 
appliances no longer carries much risk. YMMV of course.
