I hope one day I will become as good as you. Thanks a lot what you’ve mentioned today zenre to me,Tedelex crt TV was no power. Hi Moshe, Yes certain power supplies need a load to run properly but this one does not need a load. The first thing I did was to check on the main fuse and it checked to be good.
August 19, What we have learned from this repair case was that it is not necessary must have lots of bad components if you zeneg across no power symptom in switching power supply.
Transistors then diodes, then ics, then resistors, then caps. Hi Jackson, Good to hear from you again. Hi Parthiban, Thanks and wishing you Happy N Likes 0 Dislikes 0. Hi, It would be much clear, if you can draw schematic zeher affected section and then explain. I’ve tried testing many components but was no lucky,but after replacing ZD C18Ph everything worked fine.

I would love to sit in and learn in one of your workshops. There are few possibilities why the supply voltage was too low:. Posted December 14, Hi Saj, Thanks for the comment.

April 17, Bernie Scott July 9, at We have also provided the original image link, and you can use them at any time. A-ha this is the clue. The steps you have taken use full to every body.
Posted December 29, 2. Did you just guees the 1N? 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 fault. Sir i hope you will help me and give me a support for my job.
Dioce Justine I like the article,you have given some ints to check out some faulty d-link switches lying around in our department. I still enjoy seeing a TV get a picture, or a radio getting sound after working on it. I wish i have the extra time. Not only this equipment you need to burn in, you also need to burn in test for all other equipment too. Hi C18py, Burning in means to test the whole system power supply and the mainboard and also the component that I have replaced to make sure it really works.
When you check on the SMD resistors, diodes and non polar caps, make sure you test it off board and not onboard. By analyzing search term 10kf6 Diode Datasheetwe found most popular and high-quality image resources from online public websites.
Nice to hear about your passion. And, a portable AM Radio will confirm that other dirty signals are present that may cause health problems, like headaches, sore muscles, foggy vision, etc.!
Keep up the good work. So in this case what would be an adequate load?
Saj July 9, at Very good troubleshooting Jestine. You may have to check the bridge rectifier, power fet or even direct replace the power ic.
