Do you think your new LED TV doesn’t require an external stabilizer? Think Again!
Nowadays, consumers are being sold a myth that TV comes with an “In-built stabilizer” that is sufficient to protect the TV from unwanted voltage fluctuations and surges. However, nothing could be further from the truth.
Let’s Break Some Myths
TV has an "In-Built Stabilizer"
What the TV Brands/Dealers refer (wrongly) to as an "In-Built Stabilizer" is SMPS (switch mode power supply).
And SMPS Is Not A Stabilizer: Unlike a stabilizer, SMPS doesn't stabilize AC voltage. SMPS just converts high input AC voltages (100-290 V) into low DC voltage (12/24V) which is then supplied to sensitive TV components.
TV doesn’t need an external stabilizer for protection against voltage fluctuations
Thus, TV SMPS (the so-called “In-Built Stabilizer”) is itself at risk under varying input voltage conditions, and its failure leaves other sensitive and expensive components of the TV fully exposed to high AC input voltages.
The truth is, the so-called "In-built Stabilizer", can’t offer foolproof security to TV’s sensitive components from voltage fluctuations / spikes as a V-Guard Stabilizer does.
We have validated the same with tests* that clearly exposed the weakness of TV's SMPS.
Low Voltage Test
When TV SMPS gets exposed to continuous low AC voltage (i.e., 130 V instead of regular 220 V), then its temperature rises from a normal of 40-60 °C to 70-90 °C leading to thermal stress. Continuous operation with this amount of thermal stress may lead to SMPS failure. (This thermal stress may cause wear, tear and general component degradation, which may not be noticeable until failure).

Thermal rise @ 130V (low voltage) – 72 °C
TV SMPS Heat Map
Thermal rise @ 220V (normal voltage) – 42 °C
High Voltage Test
When TV SMPS is exposed to continuous high AC voltage (i.e. 270V instead of regular 220 V), then its temperature rises from a normal of 40-60 °C to 70-90°C leading to thermal stress. Continuous operation with this thermal stress may lead to SMPS failure. (This thermal stress may cause wear, tear and general component degradation which may not be noticeable until failure)

*Based on V-Guard's internal tests conducted at its R&D centre
And that’s not all:
TV SMPS may not be able to guard against voltage spike
Voltage Surge is a common phenomenon, especially when the power returns. It could also result from bad wiring, lightning strikes, generators, unfiltered electrical appliances etc. Since SMPS are of different makes (brand) there is no guarantee whether it has the feature of surge protection or not, while V-Guard Stabilizers always come with surge protection. Look what happens to TV SMPS when voltage spikes.
