application pdf about trobleshooting

hello...
please introduce a good & application link or content or text about troubleshooting in electronic circuit so that i understand what is the cause of the problem in my circuit through the samples that are in this link or pdf
i don't want the book about testing components or about how can i use the meters
thanks alot

Hi,

You need to log in to read this book, it seems:

http://accessengineeringlibrary.com/browse/troubleshooting-electronic-equipment-includes-repair-and-maintenance-second-edition#c9780070483576ch02

Maybe if you say what your circuit is and the symptoms, and can post a schematic or a device name/photo of the pcb, another member may be able to suggest a more specific course of action.

I'm not very experienced at troubleshooting, I just try to be methodical and logical/analytical about the procedure; assuming you understand how your circuit should work, checking supply voltages, signal voltages, frequencies, etc are performing correctly in a methodical manner is one way of locating a problem, after a visual inspection for any unusual/damaged parts or broken tracks, etc.

A search online using a few different search terms, especially related to your device and the problem, should provide links to websites with tips and tricks or "typical" faults.

this link wasn't useful for me..because i am not a member of this site & i can't become a member..because i am not the student of the universities specified in this site
anyway thank you for your answer
