Hint for audio OK,No video problem

Most of the time in TV servicing TV s come with audio OK,No video problem.
My kind suggestion is before going into trouble shooting video and H-out section, slightly increase screen control of LOT. Due to vertical failure some time it will be h-line. Due to less screen that H-line will be invisible.
If it is H line trouble shoot vertical section else as usual.

L G T. V a strange problem(exclusive in e-care blog)


There was an LG TV came for repair. The problem was the TV gets switched on initially runs for
10-15 mins then suddenly comes to stand by position.
Initially as usual I thought it was a dry dry solder. I thoroughly checked for dry solder. but the soldering on the board was also almost OK. I touched up all the crucial soldering points for safer side. Then I swished on TV , after 10 mins it came to stand by position.
Then I checked out with my senior who have a 25 years of electronic exp. He told in LG tv this type of problem occured before to him also . The cure is nothing but replacing LDT(line driver transformer).
Then I did the same. I replaced LDT .
TV is working fine now.
In e-care service centre we repair 4-5 TVs average a day. other than that many nos of other electronic devices. Sharing all the experience gives a happiness.But time doesn't permit.
Any way next time when u come across same problem with LG tv. Just replace LDT. and say thanks to my seniour frnd.
Regards

About waste e-books

I have seen many websites selling e-books related to electronic troubleshooting.
Even to test the contents I have purchased 2 e-books also. Then I got shocked compared to
the hype given to the e-book the contents of the e-book was nothing.
So please think before purchasing such kind of e-books.
When there is huge information is available on almost all the topics why to waste money on that.
And also I want to tel you another thing one good multi-meter itself is enough to trouble shoot all the problems of electronic devices according to my 8 years of experience.
so don't get tempted to buy waste e-books and self designed tools.
Even I have recieved threatening e-mails when I declared to publish free e-book.
They thought I may disturb their business.
Any way I am free of many busy schedule now....
You can expect more postings in this blog...
Thanks and regards

Profession of electronics repair

Chapter -1

Profession of electronics repair

By- M G Raghavendra Kumar


Disclaimer : No copy right, free to edit,circuilate.

Hi every one,

This is the first chapter I am sending you people. I had an idea of comprising all the details of electronic repair document in to one whole book, but of late I joined by a senior friend who gave me a different enlightenment of electronics and related business. So, I decided to go step by step. My first chapter will teach you how establish a service centre, also how to establish yourself as a good technician in your locale. It is very important to learn how to manage all the work pressure given by the trouble-shooting process and also customer handling.

If you learn only repair you cannot be a successful technician. You should also be a good business man to establish and popularize your business. I hope all the best for your future endeavor as well as learning process.

You take any business it consists two parts

1) Process part

2) Business part

In the process part we always have the actual work to the customer and in the second part we will have the business. Person who lacks one cannot run any successful business. So, it becomes crucial to any person to get expertise the in the process as well as business.

In the field of electronics in the process part we have component testing, troubleshooting, and repairing aspects, in the business part we have customer handling, establishment process, money making as well as advertisement part.

In this first chapter I am going to describe you how to establish the business and handle the customer as well as building your business network.

I am going deeply and consistently. Don’t be hurry in the process of learning.

I just wanted to share some field experience. The main intention of this chapteris to learn and teach. The profession of this electronics is always a challenging one. There is a pressure from customer side. They are very much addicted to the entertainment devices like TV s and Music systems. They always expect speedy service from your side. They also want the device to be repaired perfectly. They also expect you to repair the device if it gets a problem again with in a short period of time without any payment.

This is one side of the challenge. Another side is the technical one. You need to service them correctly after trouble shooting. But my sincere advice is if you are really capable of doing that you can earn a lot. People don't mind paying any amount of bill if they are satisfied once. Also I advice technicians to learn how to service washing machine and freezers, They are easy to repair and can bring good money also.

And about income, don't run a charity business. Be strict about the financial issues. Also try having good customer links. Once if u find they are good people try give the best.

They will refer you to other people.

Also distribute hand bills and News paper ads in local market to get more customers. Have visiting cards always with you. Whenever you meet new ppl give your card.

The repair career of any electronics is very good if you have a craze for it. Try to be professional always. Always have good relation with other technicians. Always inform the customer about the total bill through telephone if it needs to be of more cost.

The knowledge is your strength.

If you have any queries regarding customer handling please feel free to ask me.

The general tips I want to share with you people are as follows.

1) Don’t attempt any kind of service when you are in hurry and restless.

2) Don’t work under pressure.

3) Please make sure that, you have kept all the necessary tools nearby you before starting the service work.

4) If you have circuit diagram and the IC details of the circuit with you, please refer first before staring any service.

5) After opening the system, carefully at least for five minutes search thoroughly for any dry joints, loose connections, burnt components, bulged capacitors.

6) Also keep in mind that, most sensitive components in any electronic circuit are the semiconductor components like Transistors, ICs, Diodes and if used fuse and fusible resistor.

7) Most of the time the loose contact inside the selector switch (if used) will be the main faulty component in the circuit. Above method can be used to correct the selector switch.

8) Don’t hesitate to ask any senior about the doubts you are having.

9) Whenever a senior starts working on the circuit board, keenly observe him what he does, how he trouble shoots. Also learn the techniques which you found use full.

10) In order to get the good results always put good quality components.

Above are some key points in order to ease the work.

From next week I will be sending you all the e- book’s content section by section. Until then please be prepared with the knowledge of electronic components checking.
