Yes, you too can be the proud owner of a home-entertainment system and it doesn’t have to cost you a small fortune. If you have ever wondered how your mates get to have sound booming from seemingly every corner of the house when merely watching TV, we have the answer (naturally!). All you need to do is connect your TV to your video machine to your Hi-fi (these don’t have to be top of the range) after having acquired a couple of cables to make all the connecting possible.
You WILL NEED
(This will vary depending on what it is that you are connecting to what.) Read the rest of this entry »
Downlighters are ceiling fittings of tubular shape alloy containing reflector bulbs or spotlights to produce pools of light on the table and floor against a dark ceiling background. They can be mounted as close- ceiling fittings but there are also versions for sinking flush with the ceiling and some are semi-recessed. The flush version, and to a lesser extent the semi-recessed version require a deep void above the ceiling.
These fittings are also mounted flush with the ceiling but instead of producing pools of light on the horizontal plane, produce them on walls as part of a lighting scheme. Colour lamps and coloured walls produce the required effect. Read the rest of this entry »
Whether cheap and simple or astronomically expensive, all decks are averse to dirt and debris which is statically attracted to the vinyl record. It then damages the stylus resulting in the all-too-familiar click, pop and jumping of the track.
Sound is stored on a vinyl record on a continuous groove starting at the outer edge and finishing at the centre of the disc. The groove has microscopic ridges proportional in size to the sound wave that created them. When the record rotates, the stylus is deflected by these ridges as it runs in the groove. These minute deflections are then amplified. Two requirements must be met for the stylus to track correctly. The first is that the groove of the record is free from all blemishes and foreign matter to which the stylus would react. The other is that the arm holding the stylus must apply just enough weight to hold the point within the groove (usually 1-2 grams) but not so much as to create excessive wearing of the groove.

There are no faults with CD players that are within the capabilities of the D-I-Y repairer. Do not attempt adjustment or servicing to any internal components; leave it to a trained service engineer. However, looking after your equipment properly minimizes the possibility of faults occurring.
The first consideration is the positioning and environment of the player. Do not place a CD unit in strong sunlight, near heat or in damp or humid conditions. The CD system requires very close tolerances to be maintained for accurate disc reading and sound reproduction. Read the rest of this entry »
Store tapes vertically to help prevent their stretching or loops forming and always put them in their cases tape face in. Do not store them near magnetic sources, such as loudspeakers or motors. As the signal is recorded on the tape in a magnetic format by the video, other sources of magnetism can distort or blank it. Do not store tapes in direct sunlight or where temperatures may be too high or too low. When hiring tapes from video clubs, check thatthe tape and cassette are in good condition. Do not touch the tape because grease from fingers will damage both tape and video head, but inspect the entry points for dust or flaking of the oxide (fine brownish powder or flakes).

Most households have at least one item of video and audio equipment: television, video, sound system, CD player and so on. As a rule, it is not wise for the amateur to attempt to repair such high tech equipment, as this requires expert knowledge, expensive equipment and detailed service manuals. The intricate nature of internal mechanical and electronic components and the high voltages make it inadvisable to remove panels or outer covers. It is more sensible to leave this to the skills of the trained specialist. Read the rest of this entry »
The brush roll is supported on bearings at each end so the barrel rotates freely. Types of bearings, barrels and brushes differ from model to model as well as between manufacturers. Some manufacturers supply individual parts for the brush roll, such as brush strips, bearings and barrel; others supply only complete assemblies. The brush roll on some models may have removable brush strips, whereas others may be a solid brush roll of wood or plastic with fixed brushes. A small selection is shown here to highlight the differences. Read the rest of this entry »
The upright style of vacuum cleaner is perhaps the best for large areas of carpet. It is especially good at removing dirt embedded within the pile and pet hairs from the surface, even on sculptured carpets. A drawback with the basic upright cleaner is its difficulty with cleaning stairs. The problem has been overcome with the modern combination of upright and cylinder cleaner. This type may be the best option if you have large areas of fitted carpet and staircases. The motor within the upright cleaner creates the airflow (suction) and drives a rotating brush roll, often called an agitator barrel. Read the rest of this entry »
Cord rewinds are now found on all types of cleaners, from simple hand-operated versions to the fully automatic rewind at the touch of a button. Many auto cord rewind systems use open coil springs and great care should be exercised if a stripdown of these systems is called for. Protection for the eyes is recommended. Goggles afford adequate protection from the spring itself or any item that it may throw out in the event of its slipping from position.
Operation of the cord rewind relies on tensioning of the rewind spring as the cord is pulled out for use. A small brake pad prevents the immediate return of the spring and cord drum to its original position. Read the rest of this entry »
