Troubleshooting is a practice of analyzing the causes, checking the defects, testing for errors and providing recommendations to correct it, to make the complete system fully functioning at the desired conditions. The main objective of the whole process is to turn the equipment back into operations – and to check whether there are systemic errors or problems caused by design, production and/or operation. Electronic displays and embedded system are widely used in various industries and sometimes it demands bug fixing. Hence, it becomes necessary to approach right troubleshooting practices.
The entire process of research and bug fixing depends on the ability of troubleshooter to solve the issue economically and effectively. Electric displays troubleshooter process includes different methods to fix the issue depending on the combination of elements, the field of application, and area of improvement. Although, there are some basic guidelines which remain unchanged during every process of troubleshooting. Let’s discuss the seven-step troubleshooting philosophies that are critical to fix errors:
- Identifying the Failure
This step is performed to assess whether the failure exists or not. For instance, electronic displays cannot be operated without the proper supply of electricity at proper wiring schematics and wire and connector specifications so at forehand it seems to be simple troubleshooting. It is wise to check for common problems and failure symptoms before stepping into depth. Make sure to examine the specified performance of equipment to recognize the actual failure.
- Elaborating the Failure
The objective of step 1 is to accumulate information about the issue. At this stage, the details are provided to reduce the problem sensibly. It is better to begin the troubleshooting process with more information on the hand, documentation and its results together with all related technical specifications and committed details for the given device under test (DUT).
- Listing of Possible Defective Functions
It is good to maintain a proper list of faulty functions so that all of them are checked at the end. At this step, note down all the issues with its specific area to lower down defects in the future. Also include customer in such process to get more detailed information and to educate customer for further projects.
- Finding the Area of Faulty Functions
The goal of this step is to identify the exact area of the system that is generating the issue. First, check all inputs, outputs, flows, and pressures related to the areas of possible faulty functions. Evaluating the improvement area saves a lot of time and takes the whole process in the right direction. Doing so includes several kind of testing and analyzing equipment, generates lots of testing results and give finally a full understanding of the errors found.
- Evaluate Each Component in Faulty Functions
At this step, schematic figures are used to ensure nothing goes unnoticed. It is good to examine each component and setup to recognise which element is the reason behind the reflected symptoms. Troubleshooters may remove the component and test it to fix the problem – if possible. Unfortunately some errors are more critical the others: a faulty part can be exchanged – but how about the reason to create such fault? If it is caused by technical design problems or malfunctioning or improper production processes the situation is much more complex – and needs quite a bit of education to all involved levels on the complete food chain creating and producing and also finally using the given device under test (DUT).
- Analysing the Failure
In this step, a troubleshooter may decide the failed component is going to be repaired or replaced. This needs an in-depth knowledge of component failure modes to complete the evaluation of a failed unit. Once the root cause has been identified different options of further action need to be decided to get most efficient efforts for the customer
- Verification of Defects
Once the equipment gets back to operation, look for all the functions that have been causing problems. However, the bug has been fixed and is functioning properly; it must be checked and verified well to prevent future problems – but more and more errors cannot easily be fixed by exchanging some parts or resetting some software, because they are “built in” by improper design, to cheap components, overestimated functionality or simply bad (or no) fit for function
Along with the above-mentioned steps, it is wise to take physical, chemical and mechanical basics of electronic displays into account. When it comes to analyse, find and hopefully fix the bug in electronic systems, consider approaching practiced and worthy electronic displays troubleshooter steps for successful equipment operation in the future.
