pls if anybody that have ebooks on electronics repair should please share it. ebooks like how to troubleshoot SMPS, HOW TO TEST ELECTRONIC COMPONENT, etc. especially any one from jestine yong. Thanks.

Howdy folks! I'm an artist in the video game industry, and my job entails making a lot of mechanical and sci fi assets. I thought it might be a good practice to start disassembling some electronics to be more familiar with how real electronics are manufactured and assembled, which is how i found my way to these forums.
When I started researching what tools I might need, I quickly encountered the warning "Some devices can maintain a potentially lethal charge in their capacitors, even up to years after last being powered on", which was enough of a scary thought for me to... -
This relic from a technology path that came to a dead end (but still has historical interest) was brought in with a dead SMPS, which is based around a MK1210 device. I got it going after a battle. It seems to have a strange design - if it's not getting feedback that the secondary is OK it cause the big FET to go into full conduction and overloads resulting in a blown fuse at best or something worse! I'm using a Dim Bulb Tester (70W/230V) which thankfully has saved the day a number of times whilst repairing.
Now, it loads a CD OK. The motor voltage output (which is built onto the SMPS... -
Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.
i know that in linear power supply the noise will be very low comparing to SMPS supply.... -
I have this Huntkey HK340-72FP PC SMPS where I am facing a strange problem where the SMPS shuts down when the load on any of its 12v output rails goes above 2 amps while the rating of each 12v rail is above 10amps capable.
I have checked the following:
1. All output caps are OK, and all output rails read correct voltages at no load
2. All output diodes are OK
3. NTC is ok
4. Hi voltage cap on input correctly reads 150uF on LCR meter per the spec, also the bridge rectifier is OK
5. No short in main switching MOSFET
6. All other components... -
I have a question since I am new here and I don't know if this is the right forum to ask these questions or if I am wasting your time.
I am 67 and have a lot of Radios and Electronics I grew up with which puts a lot of them at 50 years or older.
A lot of the capacitors are obviously bad but this is my problem.
An example would be the Panasonic RC-7469 Clock Radio and the Panasonic RF-888 Radio.
I have others like a Canon L-162 Nixie Desktop Calculator 110AC, etc.
I have the Service Manuals to some of these and other electronics I have and grew up with and...
