What has a more “harmful” effect on an LED TV?

Question

LEDs

There is a voltage stabilizer for the TV. When there is 200+ V in the network, the stabilizer passes the current in transit. If the voltage drops below 200, the stabilizer windings turn on, and the output loses current for a second. It turns out that the TV turns off for a second when the stabilizer is turned on.
What is "more harmful", such shutdowns or the absence of a stabilizer at all?
PS The voltage can drop up to 140 V (gradually).

Answer 1

Most modern TVs allow operation at voltages from 110V to 240V.
In fact, they can even work from 80V.
For TVs, voltage rises above 240v are dangerous, even for very short periods.
So the main role (task) of the stabilizer is the absence of power surges in the network.

Answer 2

Take a UPS - it does not turn off.
What is more harmful - it depends heavily on the device itself
