Hi jestine,

Your articles are always very good. Thanks for posting them to the

Good Day,

I just want say that i enjoying reading your website even before the first time i saw it i included on my favorites on my computer and i always open it everytime I surf the net I always try to check if you have any new topic. I can proud to say that your my idol i hope i can be like yours someday. I'm on the process on polishing my skills on my chosen career I been 2 year in this field i found it really great and i understand the feeling you have when you love electronics . I planning to attain my peak skills on my job when i reach 30 I hope I can do that any way I wil just try.

I am biomedical service engineer I handle different medical equipment I'm not experience having major problem servicing some medical equipment except the dialysis machine it seems its easy to troubleshoots a medical equipment bec. they equip with microprocessor telling you whats wrong with them I just replace the board causing the unit malfunction. In my job I cant repair it by parts bec. the manufacturer does not allowed it and the main major reason is to make sure the unit is safe to used by the end user and patient and to ensure precise & proper functionality so our S.O.P is by board level.

I want to satisfy myself that i can able to troubleshoot and repair a equipment by parts i know i cant do that on my job.My plan is to repair a tv or vcr..etc. to practice my self on by parts. Thanks again for your tips how to troubleshoots a certain parts of equipment. Hope you understand i talk to much, I'm so happy . Keep up the good work sir.Thanks you so much...


Hi Jestin

What an excellent person you are. God bless you. I live in Spain and always
wanted to be a free technician for human kindness. But I could not be. Here
I have always seen people throwing monitors, videos, and other electronic
items whom they could not repair, and many times I feel sad for those people
who don t even have luxury to have these things. You and your work, I
appreciate and salute you.



That is very nice site and may God bless you.



Dear Jestine:

Yes, the transformer is dead allright! You were absolutely correct. I have 120 volts entering and nothing on the output at all. (Now that you taught me how to use my meter)

Thank you very, very much for your patience.

Tomorrow, I begin the search to find a new transformer!

Very Best Regards and thanks again,



hi justine

i will take this time to thank you for all your support now i can repair the monitors & tft without any problem. i used to fear monitors coz i didn't know how the circuit works but when i read your notes & repair tip now i understands.

i came to that when you don't understand the circuit you can,t repair any thing.

for the computer mainboard its so easy they usually take out the mosfet which i remove the one which is in the AGP circuit & put it in the memory slot circuit & the mainboard start working there nothing to buy is that people don't how PC power supply works

now irepair the following
power supply , ups
that you very much happy new yr
kenya is fine

Sometimes later............and do you now what now i,m repairing about 3&5 monitors, lcd, laptops screens per dayand i have been learning through your website even i decided to print your picture and put it in my small office and onother in my house do you why the question i have been asking u about VDU,LCDs made me who i,m today, now i,m getting about $250 per week coz of you.i have sign contracts with 4 Tea factories. remember you told me computer mainboard are cheaper than monitors, last week i had 12 compaq s710 with int no display and the problem was just dry joint.

Hi Jestine I have just just receieved your article on SMPS and greatly appreciates it, and you sending stuff like your electronic servicing E-book is great thanks a lot.

Ali Majeed

What actually captivated my response is your philosophical approach and that you could or rather,
have excelled in your interests. It makes me wonder how you could have achieved so much knowledge in your own field and likewise, other diversities. Teaching, developing your own Webpage and Internet marketing; oh wow!..You see, it’s not the status or the amount of income that envy me. It’s the
amount of knowledge and achievements that you guys acquired that made me ponder.  I believe, but how do you (not in any particular order) indulge and manage time, effort, concentration, determination, perseverance and err…I don’t know the correct word or phrase, you tell me...Alas, I’ve two sons whom I hope, could learn a thing or two from you. Not just in terms of academic or technical know how within the courses that I would like to enroll them. More so important are the qualities of endeavours and wisdom in person.



your site is just oustanding !!

thank you again !!

Patrick Montaron

thankyou dear justin,...
thankyou for hoisting up this website and being kind enough to extend informations which otherwise would not have been affordable for me.i am a working biomedical engineer.many doubts that had occured in my career when i refered to other experienced hands ended up in either wrong information or angry remarks as"you do not even know that?" which finally proved that they themselves were doubtful as i am about these queries that rised. only a real  genius and intelligent person can do what you are doing now. i bow before such kind heartedness.it really is making a change in my career .

Hi Very Dear Jestine Yong,
     I am 100% glad that I've met you (though out of physical contact) and I'm glad to know you (though by Internet Sharing behind the Web).  Thanks for your thoughtfulness and concern.  You are a blessing to me personally.  I am actually a fledgling in computing and IT world earnestly trying to learn and become practically sound in areas that interest me.  I've found all your articles very resourceful.  Thanks a great deal.  Please do know you are ministering life to somebody behind your screen - keep sending the stuffs.  Am nurtured and experiencing growth by them. 
     Right now, am trying to learn how to read electronic hardware components, trace circuits, and make a neat drawing of circuit schematics, troubleshoot for problems and effect necessary repairs with little or no assistance before I discovered your site a couple of days ago while groping about in the web for help.  God saw my needs and placed your website in my hands for solutions.   I will always let you know how am doing and going by it all since I've found you a man of true concern and care.  If not for distance (Nigeria-Malaysia) I would have loved to always be with you in your repair shop/office for real life contact, mentoring and practical on hands experience.  Be that as it is, am still glad and confident that you are and will be of good help to me leading me to my dream.  Am really glad to know and meet you on net.
Thanks and Godbless.  I love you as my IT Father and Mentor.  And love to hear from you always.
Yours baby behind the web,


I really enjoyed all your articles and was really suprised
to find someone locally sharing his knowledge on web........
You really have have inspired me especially after visiting
your website.

Thanks and GOD Bless you too!

Love in Christ,

thanks Jestine Yong




Hi Jestine,

I wanted to send you an e-mail expressing my appreciation to you for resurrecting your repair article series. It was and is again one of the best sources of reliable information for techs in the repair field no matter how experienced they happen to be.

Your series was very helpful to me as I was taking my electronics from a classroom environment to the bench. Yourself along with others like Sam Goldwasser, and my personal friend Harry Fogarty are providing a continuing on-line educating resource that myself and others still take advantage of. When I first discovered your articles I was struggling (from inexperience) to make a bench job "pay" for my employer. Now, thanks partially to you, I run my own little repair company.

Thanks a million, and keep on with this Great Job! Very few people are gifted at imparting practical electronic repair knowledge in a usable form.  I think that you should be more recognized by your peers for doing so. Freely "Giving back" so to speak on the internet.

First of all I would like to appreciate you for sharing your long time experience on the internet to let other technicians to improve thier skill of electronics repair .

I am In Ethiopia in the city of Awassa I was working in the Educational media center as maintenance techniccian I have an experience in repairing Transmitters and some studio equipments .In that time I was familier with using service manual of the equipments at the time of servicing . But I came to Awassa in the Capacity Building office ( governementai office ) as vidio conferencing tecnician But most of the time I am idle .So I decide to start my buisness in maintaining electronics equipments like dvd, vcd and TV . That is at this time I made a contact with you I can really say I am lucky I can contact you by email whatever the problem i face during maintenance I will mail to you I hope you will help me .

Hi, Sir!

thank you a bunch for your repair tips. I got a Master's in Electronics.... I took on a job at a local American company as Computer & Electronics repairer, linux mail &web server and Windows 2000 server administrator. I am very good at IT but not at electronics repair.all is theory that I know. I've never used a screwdriver neither opened a monitor case. my concern was to find a tv repair website. after many research attempts for many months to no avail, I finally ran into your precious website. what a relief! now I am confident. no more awe. I am very at ATX power supply repair. it left with testing monitor flyback. I still can't figure out the pinout. thanx for your plenty newsletters.

God bless you!
