Tip & How-To about Televison & Video
Have you ever taken the back off an electronic piece of equipment only to find that the fuse is blown and you don't have a fuse handy?
Not to mention that a trip to the Radio Shack is miles away and this is usually the only place to get electronic parts to exact specifications.
Otherwise, getting an item like a fuse by mail could take up to a week or more and when you do get it you find that it did not make any difference at all with turning the set on.
To help out in these situations, I use a handy shortcut to the time consuming fuse problem.
Now this may seem a little unscrupulous to some, but I have tested it time and time again with no further damage to the electronic unit.
Most people have broken AC corded items around the house that have not been thrown away yet. I have found that these AC cords that were used to plug them up in the wall socket have tiny strands of copper wire in them.
I have stripped the cover off the AC cord and taken only one strand of the tiny copper wire and tested it to be about 5 to 6 amps which this ampage is usually what most electronic units have as fuses on the AC input.
I wrap the single strand of copper wire around the blown fuse as a test to see if there is a short in the electronic circuit. If it blows the strand then I know there is a problem, but in a lot of cases if the unit comes on, then I know that I have only a blown fuse.
I don't leave the strand permanently, but leave it just long enough to find the proper fuse so the connection will hold properly.
