What happens with my AC Adapter laptop:

I plug in the cord, and it says ”Plugged in Not Charging”. I can only run on AC. That’s it. I’m so fucking furious why it doesn’t work.

hello i have a question that i think you could have the answer i just bought a us version super nintendo 1chip 01 on ebay and i had and old U.S Snes Ac adapter that is supposed to output 10V Dc … i tested the voltage from the tip and it reads 13.70 volts DC (unloaded) is it safe to use it ? i dont want it to do internal damage at the price i paid the console haha

Zippy DoDah says:

Does the adapter that plugs into the wall typically have any kind of fuse / circuit breaker inside it?

Mouser

I did a really dumb thing and plugged my Alesis electronic drum kit adapter (9v AC/AC) into a guitar FX box that’s 9v AC/DC). The good news is that the FX box wasn’t damaged. The bad news is that my Alesis adapter doesn’t work anymore. Can it be fixed?

Nesmaniac says:

I like how you repair stuff because you do it right to where it has best chance of lasting. So many people half ass stuff these days but the way you fix it I would say it would last as long or longer than factory.

ÆMEROX says:

To anyone who is reading comment. I ask, is it possible to use heat shrink tubing at the end of my newly replaced AC adapter plug to secure it rather using super glue? 14:40

Rocket Rider says:

Thanks.

GameTechUS says:

You just asked the same question that has already been answered:
AV fami’s take DC power so polarity has to be correct.

SevenDeMagnus says:

Hi. Does my Famicom power/AC adapter need rewinding or does it need it’s capacitor replaced? The adapter is 10v DC but the power/AC adapter is only outputting less than 1v.
The specifications are:

DC 10v 850mA
AC 100v 50/60Hz 18Va

Is it the capacitor? The capacitor spec is 16v 2200 microFarads.

Thank you in advance.

God bless, Psalm 11:7

Rusty Nuckles says:

Is there any way to reduce the output voltage coming from the transformer?
I have one that says Output DC 9V 200mA but it is putting out 19.7 volts.
What could be the problem & will this issue harm my 9 volt miditech keyboard..
Thanks for the tutorial!

triplebeamdream says:

very helpful, thanks man!

GameTechUS says:

Haha! No thanks, I have piles of them already…

My casio 12v adapter suddenly start showing 7v what can be reason is it possible to repair it.

Mr. Finger says:

You melted the green wire. Why not do it one by one.

bevoburn says:

Where did you buy the tips?

Dose this work with the switch to

Antonio Sato says:

I have two kinds of power supply, A) says output DC 10,5V and when only plugged measured 20V; and other B) says output DC 4,5V and when plugged measured same 4,5V.. do you know if my power supply "A" is damaged or can be fixed? thanks in advance

BRIAN WALKER says:

Do you know to re seat/ repair the ac connector pin in a genesis ac adapter? I am getting NO power from the unit and one plug is tight and solid the other wobbles like hell so thinking that could be an issue. It Has a brand New Capacitor and I made sure i Installed it correctly.

Hugo Jasach Verdugo Quintero says:

I bought a NES 001 AC Adapter on the flea Market today, first I’ve connected to my NES and it didn’t work after that I check with the multimiter and it gave me some random voltages arround 3.55 to 10.85 all crazy, after that I realize that the tip was just a bit dirty clean that tip with some brasso and it worked like a charm. It’s intresting how something so simple could make a diference, I was about to open and check if there was something wrong on the inside but luckly it was just a dirty tip.

GameTechUS says:

Cool! Thanks for sharing!

vincent avesato says:

Continuity test on cord and output plug

true_blue1878 says:

Man those tips are expensive here in the UK. If I am right they want £5 each. Anyone find them for a reasonable price??
Is this them? http://uk.mouser.com/Connectors/Power-Connectors/_/N-axip3?Keyword=DC+tip&FS=True

INVASION NT says:

i just purchased 100-240v ac/dc power supply adapter. Input :100-240v AC 50-60Hz. Output:10v DC 1000mA. Polarity:(-)—–(o—–(+) .Will this ac adapter compatible with an AV Famicom console? The AV famicom Polarity :(+)—–(o—–(-) Centre Pin Negative.i dont want to fry my AV famicom console. i wanted 100-240v ac adapter (auto-voltage) for traveling.thanks

t jay says:

You melted the wire coating where you crimped it before soldering. You should wait to crimp until the soldering is done and the metal is cooled to room temperature.

always be closing says:

Thanks for the great videos. Im going to buy you some wire strippers for christmas.

CZroe says:

The top is called a "spanner."

brentonius says:

Do they have capacitors inside? Should these be replaced if so?

Disruption says:

my nes wouldn’t turn on and began to smoke but I’m not sure if the ac is the culprit as I just put in new pin connector and then it just stopped working does this video help?

how would u open an adapter for an acer a100 iconia tablet?

Ilkhom Muminov says:

Hi, Master. Just imagine I’m your online pupil. I had a broken detail and I don’t know how it’s called, it has 8 legs.The problem is that I can not find this item in my city. There were written on the detail: "LT FOZ OB2269CPA" with small letters. Can I use another detail instead of it? if it is possible, PLEASE master, write down what kind of detail I exactly can use for it?

Great job,my pal snes adaptor doesn’t work properly since 2001 so everytime i wanted to play, i had to bend the cable in such position in order to power on the snes, HOWEVER, one slight move of the adaptor will shut down the snes.
Because of this i instead use my pal nes adaptor for the snes over a dakage, but still i wish i could repair the official pal adaptor because it looks more appealing.

TheDarxide23 says:

If I’m not mistaken that bit is called a "snake eye" bit.

ReidCircuits says:

What kind of jack tip do I need for the Sega Genesis Model 2? Also where can i buy?

GameTechUS says:

LMAO! Uhh you’re welcome…

true_blue1878 says:

Only 1 in 4 adapters open up that easily though. Most are snapped together with plastic locks and you have to get a knife in there and pry the bugger open. I would like to see how you open those types up without damaging the case. Also how do you actually repair the supply itself??

GameTechUS says:

No, AV fami’s take DC power so polarity has to be correct.
You could take the AC adapter apart and reverse the leads to change the polarity.

Gary James says:

Great video! Very helpful:)

Eduardo Schiavo Dachari says:

Great video man! I have a NES and it is not turning over, tested the AC Adapter into another game and it worked correctly, the problem is not the Adapter. You know where I can begin to unravel the problem?? Thank you!

windandkitesurfer says:

for my Boss psa-120t it was the wire coming out of the unit – your video showed me where to look.  Taking the unit apart was more tricky.  Removed the two screws from the back but had to hit the seam with a chisel and hammer around the perimeter to gently open up the edges.  Eventually I got it open, cut and re-soldered the wires and now working as good as new.  Thanks for your video – it certainly got me on the correct track!

username says:

I opened mine reflowed all the joints on a snes PSU with a soldering pen and now its not showing no more screen problems steady power again! Thanks for your help

brentonius says:

Could someone here please link me up to one of those screw drivers?

Brian Henry says:

The bit he is using is known as a Spanner Bit.
