- Useful video on how to fix an AP that does not turn on due to a burnt Diode. This is common fix for an AP that had a power surge/outage

If the video has better and clearer resolution It would really be good. The tiny details are good as well once clearly noticed. Thanks a lot
If you have the new revision of the AP AC-LR and the PCB looks different than this video, you need to remove the diode marked as "D23". It is located on the opposite side of the antenna, near the border of the PCB.
Thank you for your comment. Do you know the purpose of this diode in these PCBs? Are they for flyback current protection or reverse polarity protection?
@@arun.sekher I think it gives overcurrent protection, as far as I know. I just removed it and never replaced it, my AP is still working fine.
Hello, I think it's problem only UniFi 6 model's. I have old model AP LR, but its working without the any issue.
Hi D Z, amazon does not sell those anymore. Do you know of any other stores I could buy them? Thanks.
Hello Johnny, you may try to look for this part: SMBJ24A-E3/52
I took a look at Amazon and see one result (3rd Party Seller): www.amazon.com/Vishay-Tvs-Diode-600W-Do-214Aa/dp/B0089MCN4C/ref=sr_1_1?crid=2LKEC46ZOS912&keywords=SMBJ24A-E3%2F52&qid=1694469095&sprefix=smbj24a-e3%2F52%2Caps%2C198&sr=8-1
Hope it helps, thank you.
URL link is no good!
Sorry about that, seems the seller isn't on Amazon anymore. Your best bet would be to look up the part: SMBJ24A-E3/52
Sorry I don't have any other link O can provide.
I might start counting how many times you said Ummmm
