Power Surges and Your Television

08 May Power Surges and Your Television

We all know the reason that it’s wise to put a surge protector on your home entertainment system. But what most do not know is that there are many different types of electrical instances that can reek havoc on your expensive gadgets.


We’ve heard about the surge, which is a 2+ second jump in voltage, but there are also spikes, sags, and outages which can all affect your television set. A spike is an instant and fast jump in voltage but can throw hundreds of volts at your gadgets. When you hear of power supplies and motherboards being outright fried, it’s due to a spike. A sag is similar to a surge but it’s a sudden decrease in voltage.

Sometimes there is little one can do, especially if your house gets directly struck by lightening. Lucky for us, those odds are pretty rare. There are a few types of surge protection that exist which allow consumers investing hard earned money protection from smaller surges. The simple 30-50 dollar surge protector is often better than nothing, but we it may be wise to research more aggressive surge protection before betting your devices on it.

There are many other solutions, some are expensive, while some are inexpensive, but come with some risk.  Metal-Oxide Varistors (MOV) provide an inexpensive but become short term solution with long term risks. A MOV is effective at setting the voltage not to go over certain values but can burn out fairly quickly. Line conditioners, uninterruptable power supplies (UPS), and whole home surge protection are probably better investments worth looking into because they can last for several months. The main drawback with those options tend to be cost.

Keep in mind too that sometimes a television that has been hit by a surge can be repaired. That’s where we come in.
