‘In-Built Stabilizer’ in smart TVs misunderstood, experts urge external protection

The widely used marketing phrase “in-built stabilizer” in televisions is often misunderstood by consumers and does not provide the same protection as a dedicated voltage stabilizer, according to industry experts. Modern televisions are fitted with an SMPS (Switch Mode Power Supply), a component designed to convert AC power into the DC power required for internal circuitry. Experts clarify that the SMPS does not regulate external voltage fluctuations in the way a stabilizer does, despite the common perception created by the “in-built stabilizer” label.

Voltage instability remains a concern across several parts of India. Semi-urban and rural regions frequently experience fluctuation cycles, while urban households often face load imbalances when multiple high-consumption appliances run simultaneously. Under such conditions, televisions may continue functioning, creating the impression that they are protected. However, sustained voltage deviation can increase SMPS operating temperatures, leading to gradual component degradation and reducing the lifespan of the television.

Power restoration after outages can also generate microsecond voltage spikes that reach extremely high levels. According to test reports shared by consumer appliance brand V-Guard Industries, sustained voltage stress significantly raises SMPS temperatures, affecting long-term reliability. If the SMPS fails, sensitive electronics may be directly exposed to high AC input, potentially resulting in costly repairs. In Kolkata, larger and more advanced smart televisions are increasingly popular among urban buyers. However, experts warn that as screen sizes and prices rise, the financial risk associated with electrical damage also increases. V-Guard Industries has advised consumers not to confuse operational tolerance with operational safety, emphasizing that external voltage protection can help ensure long-term performance and reliability of premium televisions.
