Now you need to list probable faulty functions.
You need to divide the equipment into functional areas in order to save troubleshooting steps use functional
block diagrams or in short FP PD to show the functional areas of an equipment as well.
The detail functions levels of inputs and outputs parameter for voltage and current.
Making that diagram will save you a lot of time.
Make sure to stay the input and the expected output for each block.
Then start measuring
next.
You need to localize the faulty function.
Now that you have a block diagram with all the required functions you need to start isolating the functional
area that has an indication of malfunction knowledge skill and probe artist equipment should now be
used to isolate the fault functional area after doing this.
Now you have a clear idea what are the areas that have fault or problem and what are the areas that
are functioning properly localizing that trouble of the circuit.
First you need to isolate the circuit within the faulty unit more extensive troubleshooting is now required
within the identified fault unit look for improper voltages and provide waveforms using a of scope obvious
component of our heating all components that are blowing out so use your I use your eyes to smell and
use your hearing.
Use your ability to identify problems from their physical appearance.
If nothing is shown you need to start using your multimeter oscilloscope to solve this thing.
Each component as we explained previously isolate the defective circuit the group
after this union to do failure analysis.
Step 1 and 2 were used to recognize verify and obtain descriptive information.
Step 3 and our process allowed you to make a logical selection of the logical faulty unit step 4 provided
for symbol input output test and localize the faulty functions.
Still 5 localized default to the circuit within the faulty unit.
Step 6 will involve the actual replacement or repair or faulty circuit components.
Now that you have a clear idea what's the circuit that has the problem you can replace any faulty component
inside it or you can replace the whole board depending on the type of this plastic particular equipment.
This is it.
If you follow these four or these six steps you'll be able to make a diagram for your equipment or your
board with inputs and outputs and you'll be able to separate each of these functions into a separated
block diagram.
And finally you'll be able to identify the board that has the problem and replace it or fix it depending
on your skills.
That's it for the failure annexes.
If you follow these steps one by one you should be at the end of Step Six in the process of replacing
or making the device work.
Thanks for watching.
