Judy,
Generally it is always OK to leave electronics on. The only typical thing
that shortens the life of semiconductors is heat. When in sleep mode the
lamp and motor ( two of the biggest power consumers and heat generators) are
in standby so nothing much else is an issue.
>From a long term point of view, once electronic components get past what is
known as infant mortality, they last forever or at least for the next three
years when it is time to get the new stuff.
Possibly the one thing that can damage things is static electricity. So
when you zap yourself on some electronic gear, you never know if it has
injured it a little. If it kills it , it is more obvious.
