In this video, I attempt to repair an ADP-400FR that was sent in by a fan of the channel. These supplies are hard to come by at this time so hopefully I can repair this one.
One interesting difference is they moved the motherboard socket further and rotated the prongs 90 degrees I guess to ensure someone doesn’t put the wrong supply in (like the DR). If you’re interested in looking at another FR; I’ve yet to crack the one I have that loses power under load.
@@ToltecMerc yes, about a week after this comment I decided to list it, I have too many fixed consoles and parts laying around so I need to clean house before I do another batch.
Wow very interesting video and I always watch ⌚ your videos you are the master of the master professional electronics engineer 👃 👏 and its amazing how you can fault find 😀 keep up the good work can't wait to see more videos thank you very much 🌟 😊
Great, I'm looking for a transistor 40N60M2 mosfet my power supply get damaged due extra voltage I repaired every thing except the transistor I couldn't find it Do you know where to find?? 40N60M2, mosfet GKLTw vc CHN 204
Absolutely amazing your troubleshooting skills are . i have so many dead power supplies that i wish i was as good as u that i could fix them all. With your videos i have got the confidence to drill deeper into them.Thank you so much. Also i always discharge the bulk caps as soon I open it up. I have a question for you , i have this slim supply in which the volts on the bulk caps go v high . I replaced the caps and the 16121A but that didnt fix the issue someone else suggested a bad DAP49. What are your thoughts?
Look at the large value resistors in the feedback loop. It sounds like there is not a proper feedback from the bulk capacitors to the 1612A on pin 2. Depending on the model, could be a 9.1Meg and 1.5Meg.
Thank you for your video!!!!!!! I've tried a repair of an ADP-400FR with identical components damaged (shortage by roaches). But I was unlucky. The power supply without load stay on... when I put load, stay on for five minutes and after this destroy again diode, mosfet and dap... Any suggestion? Thanks in advance! Germano
