For example, you can have the monitor and hard disk power down automatically when not in use. For example, when the CPU chip is running it can get quite hot, and when you turn the machine off it cools back down. The expansion and contraction from the heat probably has some effect on the solder joints holding the chip in place, and on the micro-fine details on the chip itself. I don't know a single person who leaves the TV on 24 hours a day. TVs contain many of the same components that computers do.
TVs certainly have no problems being cycled on and off.
