used flow charts.

The rest is omitted.
If you want to find out possible causes (faulty part), see the column under "Cause."
In the case of the above table, the power plug may be disconnected, the covers may not be
closed firmly, the main power may be absent, and so forth.
If you want to find out the checks or action to take, make checks according to the steps under
"Checks" and perform the work under "Action."
Answer the question under each check to make Yes or No, and take the appropriate action.
Otherwise, go to the next step, and make the check under it.
