I got a phone call from a client who wanted his television
checked by a technician, it was a referral case from another client I had
repaired his gadget previously.
He directed me to his place within the neighborhood and was
able to trace his place. After sanitizing my hands, I was ushered in and shown
the television.
I asked for brief history and was told they shut it down
previous evening and in the morning the television never wake up.
I applied the power to confirm what they said and indeed
there was no sign of life even the standby light was absent.
With that I took the television to my workshop and after opening it I went straight to check the state of the safety components beginning with the main fuse and to my surprise noted it has a thick jumper wire across it and this lead me to conclude the television had a previous repair.
We can use this analogy in electronics troubleshooting and
repair…that being good at electronics repairs will depend on your foundation in
basic electronics.
This is because electronics equipment is a product of many different components (both passive and active) which work together to build a Television, DVDs, Radios or whichever other electronics equipment you see in the market.
If you are looking for solid foundation in electronics repairs and probably write your own ebook? i highly recommend to you basic electronics course by a friend and renowned electronic repairer from Malaysia Mr Jestine Yong.
When i was learning electronics this was one of the e-book which sharpened my troubleshooting skills and now i have written over six ebook.
I received this DVD player from a client who got my contact via our estate whatup group, I picked the machine from his house and headed to my shop which is around 3Km from where I live.
Upon reaching the shop I applied the power to the DVD and
noted the machine was taking too long to load the disc and after some few
minutes displayed No disc error.
I then opened the DVD player and went straight to the disc
loader section, first let me point out that the customer has hinted to me that
the machine was from another technician who was not able to solve the problem.
Usually items from other technician are difficult to repair
and therefore I was very careful because a tech with limited knowledge in
repair would do more harm to the equipment through guesswork.
So I begin my troubleshooting by doing visual inspection for
any mis-handling and noted a small micro switch which detect the Disc was not
locking and this may explain why the disc kept on rotating because the machine
could not detect the first track.
