*Warning: Do NOT work on Power Supplies if you do not know what you are doing. You can get shocks!*
It goes without saying - if you are capable of working on a PSU - it's worth checking yours and removing that silicone!
I am aware of the typo (Led, not lead...) - I often make typos...

Excellent! Interesting to hear the symptoms when the other resistor fails. Thanks for all the very kind words Chris and glad you had an easy fix with these power supplies 👍
Thank you!!! I spent hours back in 2016 trying to narrow down the fault lol
@@GadgetUK164 I can imagine! I remember you told me the fault was on the separate vertical board so that instantly narrowed it down for me so your hours weren't wasted in vain😂👍
I did some testing, I had 4 N64 PAL PSU (bought in Spain), 3 of them had an engraving ending in "M1", all 3 were identical to the problematic one.
All 3 of them had very little 'gum', so little that the 221 resistor wasn't covered with it. All 3 are working fine, your theory seems correct and I may have found a way to identify them without opening them (the "M1" engraving thing)
Nice work guys
Vince is where it all started for me, I gamed alot but after watching him I took the plunge into modding and repairing and as I'm part disabled it's given something to do with my time.

Checked Vince video, one that I could see seemed to have "M1", however, it looks like you ended in "P3"...
Mine has the light on for power but I have no video output. I’ve tried both my n64s and only the power supply left to check. That’s why I’m here 😂

220 Ohm Resistor could have been soldered in within seconds
with a dab of sticky flux "Applied via toothpick point" to the
resistors tabs and then placed on point, place a little solder on
the Soldering Iron Tip and solder each resistors end down..
For how long it will take, if you have a working PSU, it's probably worth opening it up and removing the glue. I had a faulty PSU but mine was a faulty optocoupler and blown mosfet IIRC.
Oh for a pair of long-nosed tweezers during that first 220R soldering clip!
yo..yo chris..
should any psu...or these...self discharge after being powered down...?
we had a psu we removed from one of our copiers.. left it for a day..
and boom a 400v cap still had charge...
no one died...
excellent vid

I really enjoy all of your content! It has helped me further my knowledge and enhanced my abilities! 😁
Great to hear! =D Thanks!!!
My PSU is just acting weird, when I plug it in the wall the n64 works and then after a while sometimes an hour, sometimes 5 mins. It just loses all the voltage on both of the rails and I need to let it "cooldown" could it be those two resistors? Because they measure fine. Or can they act bad when they heat up
Yes, it could be the resistors! It could also just be bad electrolytic capacitors too!
Amo l'N64,ottimo lavoro agli alimentatori!
Heck yeah! Good thing I didn’t throw much of those out 😅
I do a fair bit of work on 70s/80s audio equipment and a lot of these have the same problem as the N64 PSU - glue used around (normally) the power supply caps (have a look at Sansui glue). Becomes dry with heat, then becomes corrosive and conductive. Pain in the rear to remove, but acetone (nail varnish remover) on a cotton bud/q-tip is really good for it - just be careful of PCB markings etc as it can rub them off. Quick rinse with IPA afterwards and all good. Also - don't get acetone in capacitor cans - it right royally f's them up.
How do you solve the issue with a PSU generating noise over the image on screen?
Is it a new modern PSU or the original older one?
@@GadgetUK164 The original older one. The N64 has been RGB modded, but now with the clarity of RGB you can see noise all over the image. I have read that the cause could be the PSU in bad shape (or probably the console itself). For now I think I'll buy a "modern one", not a cheap third party ones, but one of those smaller "board" powered by an external power supply.
@@danielescamperle6022 It might be failing caps in the PSU, perhaps relating to the 12v side...
Man, in the USA there are a dozen different N64 PSU variants from 3+ manufacturers. I’ve taken apart over 100 and still haven’t found one with this fault (knock on wood). Do you think it only affects 220v models?
It might just be european models! I've got another video coming up soon on another model we got over here! I think the point is, Vince has fixed 2 or 3 with this issue, I'e covered 3 in this video, 1 other off camera since with the same issue, and I saw that another channel that follows Vince has fixed a couple with same model and same fault too. So for this european model, its a super common fault on a common model.
Yeah, NA N64 power supplies tend to be incedibly reliable and almost never hear them not working if the cable and console side connector are fine in the states, so wondering if a 220v issue.
