Protecting Your TV and Home Theater — A Plain-English Guide
Last verified: September 2026
Your television and its boxes are delicate electronics, and a surge can ride in on the power cord or the cable line. Here's how to guard both, simply and inexpensively. Rather have a hand? My number is (330) 200-8042.
Home-Theater Surge Protection, at a Glance
Your TV, receiver, streaming box, DVR, and game console are all delicate electronics that a power surge can ruin. The part most folks miss is that a surge can ride in two ways — down the power cord and down the cable (coax) line — so good protection guards both. A small battery backup keeps a cable or streaming box from rebooting on a brief blink, and in a severe storm, unplugging the set and its cable line is still the surest step of all. There's a printable 29-page version up top.
Common Questions
1 Why do I need to protect the cable line, not just the power?
Because a surge can travel right down the cable (coax) line and into your TV or cable box, bypassing a power-only protector. Run the cable through a surge protector with coax jacks, or unplug it in a severe storm.
2 What's the difference between a surge protector and a battery backup?
A surge protector stops voltage spikes. A battery backup (a UPS) also carries a device through a brief blink or outage so it doesn't reboot — and most UPS units include surge protection too. For a fussy DVR or streaming box, a small UPS is a nice touch.
3 Does my TV itself need a battery backup?
Usually not. A good surge protector is plenty for the television. A battery backup earns its keep on the boxes that reboot at every little blink — a cable box, a DVR, or a streaming box.
4 Can one surge protector cover my whole entertainment center?
Often yes — a single good protector with enough well-spaced outlets can handle the TV, the sound, and the boxes together. Just never daisy-chain one strip into another to gain more outlets.
5 How do I know when to replace a surge protector?
Watch the indicator light. If the 'protected' light is out while the strip still has power, the protection is used up — replace it even though the TV still turns on. Also replace it after a big surge or nearby strike, and every few years as a matter of course.
6 Is a plain power strip good enough for a TV?
No. A plain power strip only splits one outlet into several — it offers no surge protection at all. Look for the words 'surge protector' and an indicator light; if it doesn't say so, assume it's just a strip.
