Define Your Symptoms
When a phone breaks down, the cause might be a simple as a loose wire or a connector or a complicated as an IC or component failure. Before you start, you must have a good understanding of all the symptoms, it can be much easier to trace a problem to the appropriate component. Take the time to write down as many symptoms as you can. As a technician, you must often write problems and solutions for reference purposes – The Complete Process of Repairing will be guided in this Online Mobile Repairing Course.
Identify and Isolate
Before you try to isolate a problem within a piece of hardware, you must first be sure that the equipment itself is causing the problem. In many cases, this will be fairly obvious, but some situations might not be. A faulty or improperly configured piece of software can cause confusing system errors. When you are sure that it is a system’s hardware failure, you can begin to identify which component fails.
Because phones are designed as a sub-unit, it is almost always easier to replace a sub-unit outright, rather than attempt to repair the sub-unit to its component level. Even if you had the time to isolate the defective component, many parts are not interchangeable. So it is better to replace the defective part than try to repair it.
When a repair is finally complete, the system must be reassembled carefully before testing it. All guards, housing, cables, and shields must be placed before final testing. If symptoms persist, you will have to reevaluate the symptoms and narrow the problem to other parts of the equipment.
When you can verify that the symptoms have stopped during actual operation, the equipment can be returned to service. As a general rule, it is wise to let the system run for at least hours to ensure that the replacement sub-assembly will not fail prematurely.
Do not be discouraged if the equipment still malfunction. Maybe software settings and device drivers may need to be updated. If you are tired simply walk away, clear your hand and start again by defining the current symptoms. Never continue with a repair if you are tired or frustrated, tomorrow is another day. Even the most experienced troubleshooters get overwhelmed from time to time. Step by Step Process of Diagnosing the problem will be guided in this Online Mobile Repairing Course.
