How To Guides

If your multimeter stops reading amperes you may have blown a fuse! In most cases, you will still be able to read the resistance, voltage, and other values. Fluke has many different part numbers. If you need to replace a DMM fuse you can use either DMM or DMM-B part numbers.

An overload may occur if there are too many appliances plugged in in a room, sending too much current to the breaker. Power will go out in just that section of the home.Your electrical panel should be labeled. If the fuses in your box are have glass windows, visually inspect them.

Several years ago, Samsung released TV models with underrated/faulty capacitors. Symptoms of failed capacitors are: pink dot/start up problems, slow start up, after start up the picture starts to disappear, flickering of the TV screen, clicking noise, sound/power LED is on but no picture.

If the fuse is blown, remove it. Be sure the power is off and no voltage is present. Fuse pullers make this step easy but if you don’t have one, grab screwdriver or pliers. Gently pry the fuse out by the ends. If the fuse tubing is glass, be careful to not crush the tubing.  

Be sure you know which fuse is blown before buying a replacement. Although it is easy to inspect glass fuses for continuity, most fuses are solid and cannot be inspected visually. We like testing our fuses with either a multimeter or a continuity tester. 

Here are easy-to-follow videos on repairing some of the most common TV issues. Learn how to remove the board, replace a failed capacitor, and choose a capacitor replacement. See how to use a soldering wick and how to suck up melted solder with a soldering pump, close up.

Essentially a short piece of wire designed to self-destruct in the event of an electrical overload. Under healthy circumstances, the current will flow from one side of the fuse to the other. There are many varieties of fuses with different specifications such as amperage, voltage, blow type, size, and material.
