In order to resolve any issue, it is necessary to duly investigate the root cause of the problem. Troubleshooting is a detailed process that includes several steps in order to effectively provide the solution.
Gather the information – for any high cost repair, it is essential to know as much details as possible so that there may be adequate information on all relevant matters. The process includes gathering all the information about the equipments and know all about its workings. As the issues are addressed including technical resources and equipment operations, It is easier to understand the malfunction.
Understand the malfunction - Understanding the malfunction means that you understand how or what the process is and what portion of the process is operating incorrectly. This includes questions like, how the process is supposed to work? What isn’t functioning as it should? What would cause the results to malfunction?
Identify which parameters need to be evaluated - Identifying which parameters need to be evaluated requires a clear understanding of the discrepancy and which signals affect the suspected component. Which input signals control the component? What is the expected output from the suspect circuit? Is there a timing delay, sequence, or set point that can be verified?
Identify the source of the problem
Correct/repair the component - Identifying the source of the problem requires the technician to isolate components and evaluate circuit parameters, to isolate the circuit by group when dealing with a complicated circuit (half-step approach), and to identify the malfunctioning component using the recorded data. Armed with data, we can determine what needs to be done with the suspect component. Many times after the first round of troubleshooting, the first three steps may need to be repeated; however, now you have additional data to work with.
Verify the repair - Correct or repair the component identified as damaged based on the recorded data. Perform the required repairs to the circuit. Completing this can range from simple adjustments to a complete component replacement.
Perform root cause analysis - Verify the repair after completion. Ensure the equipment is operating as designed. Perform another round of testing to verify the equipment is in fact running correctly and that no other discrepancies exist.
