The question that has been raised at home is whether it is better to turn off 
(Standby) the TV when you leave the room for a short period. The one opinion 
that I have found on the Internet is that leaving it on only costs an small 
amount of electricity.  Happy with that.

But is there a cost in terms of stressing the components and reducing the 
lifetime for modern TVs?  We have a Samsung and a Toshiba LCD TV.  And does any 
answer relate to computer screens?

No, won't affect the lifetime of the TV either way, but will shorten the life 
of the switch on the mains socket, which has a finite number of cycles. Same 
with a computer screen - they're the same thing really bar the TV receiver.

If you want to consider secondary factors:

Leaving it on in the winter converts a tiny amount of electrical energy into a 
tiny amount of useful heat. In a damp room, better to leave it on.
