As a beginner,i’m having a hard time thinking whats the voltage value of zener diode mostly if i donnot have a diagram.

Check all semicondutors first. Keep up the good work.

Very good explanation, mr jestine, you always helping our worldt from being flood with electronics junk. There are few possibilities why the supply voltage was too low:. The smd diode does not have any code printed on it.

Liviu July 9, at 3: Thanks for sharing about the dirty power lines. HI Anand, I wish i have the extra time. Without the zener diode code and schematic and if the zener diode is shorted then there will be a hard time to finding out the siode.


If there is a ready made boost circuit then it will be easy to modify it.

Toni Kassab July 9, at 2: Iam very glad to read above article. Want to know how best regards mists lcd repair information Likes 0 Dislikes 0. Different power supplies using different type of power ic, power fet and etc. I would love to sit in and learn in one of your workshops.

Testing the power supply output connector with power on confirmed that the power supply have problem because the voltmeter reads zero volt on the output lines.

Glass diodes have a high failure rate. From your experience, are “most” of the switch mode power suply have similar functions but using different components?

This diode was tested good under x 1 Ohm range. December 28, Very profesional troubleshoting doode allso very googd article Likes 0 Dislikes 0. Cheers, Bernie Likes 0 Dislikes 0.


Jestine would you think about an article on modifying switching supplies for different output voltages? July 9, at 4: C18pb you share the idea? Your feedback on the post is welcome.

Lal Kahandawa July 9, at But I lack your knowledge of zeneg technology, and I could use some help! There are many reasons why the horizontal output Grant July 9, at True enough there was a SMD diode board location D2 that has shorted under analogue meter x 10 k Ohm range. I hope to receive more similar articles. Blown fuse usually cause by shorted semiconductor. This is a good article, Thanks Jestine. I suggest that you try it out yourself to see if it can be done or not.

Thank you Tana Likes 0 Dislikes 0.

Actually it is tough to determine the value of smd capacitor and zener diodes if they are shorted fiode do not have schematic or any bard for comparison. Jestine Yong July 10, at Merlin Marquardt July 9, at 1: How’s repair business in the music industry? I wish i have the extra time.

Juan Martinez July 9, at 1: Hi Chad, It is great to hear from you again.
