Fow to Tell if your TV Fuse is Blown?

Look at this image, this is a blown fuse of a TV:

However, there are two main ways to tell if your TV fuse is blown: visually inspecting it and using a multimeter.

Visual inspection

  • Unplug your TV from the power outlet.
  • Locate the fuse box. The fuse box is usually located on the back of the TV, near the power cord input on the power supply board.
  • Remove the fuse. The fuse will be a small glass or ceramic cylinder with metal caps on each end. You can usually remove it by pulling it out with your fingers.
  • Now carefully look for signs that the fuse is blown.

A blown fuse will have a broken filament inside the glass or ceramic cylinder. The filament may also be melted or discolored.

Using a multimeter

  1. Set the multimeter to continuity mode. This mode will tell you if there is a complete circuit between the two probes of the multimeter.
  2. Touch the probes of the multimeter to the metal caps on each end of the fuse. If the fuse is blown, the multimeter will not beep or show a reading.

If the fuse is good, the multimeter will beep or show a reading.

I hope this helps!
