What is a Fuse?

Your TV fuse is an electrical component designed to protect the unit from power surges. It is an electrical safety device designed around a conductive strip that melts and separates when excessive current passes through it. Ideally, a thin piece of fuse wire is contained within a safety sheath to reduce damage caused by the excessive current going into your TV circuit.

What Causes a Blown TV Fuse?

There are a few things that could go wrong and cause a blown TV fuse. If you recently experienced this and are wondering what went wrong with your blown TV fuse, the following could help.

Overloaded Circuit

It is perhaps the most common cause of a blown TV fuse and is a result of too much power drawn into a circuit. This will happen if too many appliances are plugged in at once. If you are constantly working on how to stream your tv while using lots of other appliances then this is likely to happen.

A Short Circuit

This ideally happens when a current is diverted on a path that it is not supposed to follow. Several things could lead to this, including moisture, insects, or damaged wires.

Circuit Breaker Issues

Circuit breakers are designed to prevent further electrical issues in case of a blown TV fuse. However, if the breaker continuously trips, it could indicate a problem.

Faulty Wiring

If your TV fuse blows, it might be a good idea to check the wiring condition before replacing the fuse. Faulty or loose connections could lead to a blown TV fuse.

How to find out if TV Fuse is Blown?

Depending on the make and model of your TV, use a screwdriver to unscrew the TV fuse cap holder. Then, carefully check the fuse wire. If you can see a visible gap between the wires or a visible metallic or dark smear inside the glass, you have a blown TV fuse.

After locating and determining the fuse condition, check the owner’s manual for fuse type or model and buy a replacement.

Warning

Circuit breakers are designed to prevent further electrical issues in case of a blown TV fuse. However, if the breaker continuously trips, it could indicate a problem.
