Based upon your post, I assume a saleman said certain voltage
variations harm TVs - typically without even knowing what voltages
are. The surge protector will eliminate those voltage variations?
There is no way around the answer without numbers. Look on a plug-in
protector box for its let-through voltage number. For example, a 120
volt protector rated at 330 volts means all those voltage variations
between 90 and 150 volts are completely ignored. Those completely
ignored variations occur often. A protector sees no voltage
(eliminates no voltage variation) until voltage exceed 330 volts.
When does that happen? Maybe once every seven years.

Knowing numbers will glaze over eyes, then a salesman can make
claims confident that those numbers will not arrive. Sorry. Here they
are. No way to answer your question without those numbers. To obtain
a concise answer, grasp those numbers.

Meanwhile, a TV power supply makes voltage variations irrelevant. If
a TV is missing required functions, then a plug-in solution (that
ignores everything below 330 volts) will fix it? Of course not.
Let's assume voltage drops so low that incandescant bulbs are only 40%
bright. Still, a TV must work just fine. Why? That is what a power
supply did even more than 30 years ago.

If those voltage variation affects life expectancy, then necessary
functions inside a TVs power supply are missing. Blame the salesman.

Meanwhile, earthed protection devices such as a 'whole house'
protector or a building wide UPS make thousand volt variations
irrelevant. That rare and larger variation may overwhelm protection
already inside a TV's power supply. But again, an effective protector
must make a short and dedicated earthing connection.

As others noted, life expectancy can be shortened if components are
too warm. 'Too' without numbers says little. TVs must work just fine
even in a 90 degree F room. Some brands may fail faster at what should
be normally acceptable room tempertures. How much heat will remove 5
to 10 years from a TV? Maybe room temperatures of 150 degree F or
higher.
