How to Troubleshoot Your Television Set

The television is just one of those appliances that come up with innovations every now and then. For the "techies", these are welcome treats. However, for people not very well-versed with electronics, they are just things that baffle the mind. Because of many people's aversion to tweaking high-tech gadgets, a TV glitch is immediately referred to a professional repair technician. This may not always be necessary if one is equipped with some knowledge about the boob tube.

Generally, there are three common malfunctions that can be handled without consulting the experts and without having to dissect the TV set.

How to deal with snow on the screen

A poor signal may cause snow on the TV screen. This may be due to a misaligned antenna that may have veered against the direction of the frequency transmission. The antennas narrow end must be aligned towards the transmissions direction. Before examining the antenna, though, you should inspect the TV cable for any breakage.

If the problem persists, the tuner may be the culprit, in which case professional assistance is required. This is because a small circuit called the "Intermediate Frequency Section" needs to be replaced by a professional. The cost of the repair will not drain your pocket. If the snow on the screen has a matching "sound" of snow, this is definitely an antenna or tuner problem and is likewise inexpensive to repair.

How to deal with the sound of snow but with a clear reception

If you encounter a snow sound but without snow on the TV screen, fine-tuning the set will do the trick. A little turning of the antenna is likewise advised. However, if the reception is very clear but still no sound comes out, it might be a speaker or volume control malfunction. Audio circuits are seldom replaced.

What to do with the vertical rolling of the picture

This is generally rectified by tuning adjustment. At times though, a small, hidden control at the middle part of the back of the set needs a little "fidgeting".

Extreme caution must be undertaken when opening up a TV set because of high voltage risks, which may cause severe shock. This, however, should not discourage you from learning basic electronics so as not to be fooled by unscrupulous repairmen who may take advantage of your ignorance.
