Repairs at AVS
At Audio Vision Services we expect repaired equipment to work for a lot longer than just our warranty period covers. This requires a vast knowledge of the repair and servicing of electronics, which is gained through many years of experience. Our work begins with explaining the process of the job, how we supply ‘you’ the customer with a quote for the costs of the repair after initial diagnosis, while recording a full description of the fault. We take in a thorough history of any previous symptoms, which often ensures the job is done fully to everyone’s satisfaction and nothing is missed.
Prevention is better than cure. A Service and Overhaul is highly recommended on quality electronics. Apart from repairing the immediate fault, we look for potential problems and investigate areas where other faults are known to occur. After servicing, the unit is usually run under arduous conditions in a "soak test" situation. For example, amplifiers may be given a "stress" test. The amplifier is run at various power levels, sometimes in excess of 15 hours. Many parameters are monitored including cross-over distortion levels, noise figures, D.C. component on the output, quiescent current, symmetry of clipping and power output levels into various loads. This test is extremely thorough and if an amplifier passes it, then one can be confident that the critical power amplifier section is in order.
Intermittent faults can be the most difficult to diagnose and repair. For example, an amplifier may give out a pop or crackle once every few hours, perhaps for just a few seconds. We may choose to replace certain components likely to cause the fault, and then run the amplifier on a digital oscilloscope for several hours. This digital oscilloscope stores and displays all noise from the amplifier for the entire time it is connected.
When you collect your repair, we will explain exactly the work that was required and we will let you know about any preventative measures you might take to avoid the fault recurring. We will also advise you on how to reconnect the equipment.
How Long Do Repairs Take? Generally, most gear is repaired at AVS is within a week. We retain a huge stock of parts from many manufacturers, as well as parts sent by courier to us daily. We rarely have any backlog as we work into the early hours if necessary. Of course, sometimes parts availability can cause delays. Commonly this is because parts have to come from overseas, or the parts are not stocked down South. We will do our best to give you an estimate of time when the parts for your repair are expected. Unlike repairs done by manufacturers, we have access to many sources of spare parts so our turnaround time is far better.
We repair just about all brands of Consumer and Professional Electronics. AVS is the preferred Warranty Service Agents for Bose, Denon, Loewe, Pioneer, Marantz, Wharfedale, Harmon/Kardon, Schaub Lorenz, Rotel and Metz.
