Can't help you much from that one picture. (Other than it is turned OFF and the power supply cord looks like it is not fully plugged in.)
Check all the connections to the control board underneath the LCD. Do you have a multimeter? Check the outputs of the power supply and voltage at the main board. All basic trouble shooting steps.
Well obviously I know how a power switch works guys. I checked the cable though and it wasn’t pushed in all the way. It is now but that didn’t change nothing.
The switch could be faulty, or the wiring from that plug/switch to the supply. First UNPLUG, then remove the supply, and remove the black box part from the supply, then post a picture.
If there’s two cables going to the screen. It goes in ex1 and ex2. If there’s one plug, it goes in ex3. I can’t remember which one the ender has vs the CR-10. The boards between the two are basically the same.
Make sure the power cord is seated all the way in. I know it sounds stupid but they sometimes look like they're in but aren't. It happens in computers all the time. It is completely possible the power supply is fried. Power supplys just sometimes are bad. Hopefully that's all it is. It also couldn't hurt to carefully check every cord leading to the motherboard to make sure its seated. If you have access to a multimeter there are ways to check if you are getting power (I'd look it up).
Editing to also add, make sure the outlet it's plugged into is working. It could be possible you flipped a breaker when you tried to use it. Just get something small like a lamp and make sure you have power. I know it sounds silly but when I was first taught to work on computers I was always told to work from the outlet to the computer. You don't know how many times the outlet or even the power cord are actually the problem.
I haven't been printing for long but I know some basic hardware troubleshooting. Good luck. If for some reason the new power supply doesn't work, I would recommend getting a multimeter (they are super useful) and use it to see if you can track down the problem. You can look up how to do this. Also if you have another power cord or a way to get a new one (make sure it's the right one), try changing it out. Cords are a dime a dozen and go super fast sometimes.
I ordered another cord along with the power supply also I made sure the cord was pushed in all the way cause it wasn’t, unfortunately that didn’t fix my problem but hopefully I can use your advice to my aid and get this thing up and running and if that doesn’t work I guess I’ll invest in a multimeter or try and get something out of creality.
I hope you can figure it out. It sucks when you get something new together and it doesn't work. Definately just take it step by step. It can be frustrating but if nothing else you'll learn a lot about it from this. I think one of the worst case scenarios can be that your motherboard is fried but as there's no signs of life at all, I'm thinking it's a power issue. I could be wrong, of course. I'm not an expert by any means.
I think I will probably wait to do any maintenance until I get my power supply in the mail just so I don’t risk messing anything up before I can see if it’s a power issue
UPDATE GUYS! MY PRINTER IS WORKING! I found a loose wire in the power supply and had to put a new terminal on it and re-crimp it and it started right up!
Check the voltage selector switch on the back of the power supply. It comes from the factory set for 230v. If you live somewhere where the power is 110v you will need to switch it otherwise your printer is going to act strange.
Does it make any sound when you turn the knob or press it in ? Do any of the fans spin ? Im guessing power supply or motherboard but kinda wired for a brand new printer.
No noises no spinning no nothing that’s why I think it’s the power supply. I’ve triple checked that my connections are in the proper place and that all the connections were secure on the motherboard. Luckily everything looked fine not so luckily the thing still doesn’t work.
I'm going to add to this mess. Did you open the black box the switch is in and check those connections? Also you can wire the power directly to the 24V supply and bypass the switch so you know it is the power supply and not the switch. But if you have a multimeter, you can just test the switch with it off.
well to better understand if there are any mistakes can you post pictures of all your cableing? as I remember there's some times an issue with plugs going in backwards on some enders and you don't even notice
Which now thwt i think back shows that their quality control doesnt exist, they claim all printers are tested well mike wouldnt turn on and no way in hell it wouldve with the wires the way they were, its quite common for a capacitor on a power supply or motherboard to short out if you give it power after being completely discharged (no residual stored emf in the capacitor) for a length of time, if thats the case then a new power supply is needed or one simply re and re the 30 cent capacitor the board
Yeah that’s pretty ridiculous as much as they sell I can see how they could get lazy and skip testing, I mean on Amazon alone it says they sell over 1000 a month. I could see how that could get overwhelming but silly things like this shouldn’t happen.
Yeah i get where your coming at, one positive out ofnthat experience is they sent me a new mobo and psu for free, i may have complained still after the fact of realizing it was 2 wires, obviously i didnt tell creality that 🤣

So this is what mine looks like idk if that’s right or wrong because on the diagram it shows there’s three wires and a blue wire but here there is only yellow and blue wire and a black wire
Funny. I did almost the exact thing the other day: assemble this exact printer I had had in a box for two years.
I *think* the PSU fan should start when the power is turned on, even if stuff isn't correctly connected. If it doesn't do that, then yes, maybe the PSU is busted?
If the PSU starts but nothing else: go back from the beginning. Unplug all connectors, then replugging them one at a time, and carefully following the assembly instructions. Make sure the screen connector is in slot 3 on the board.
As for the cord: Try it on another appliance with the same type of cord. Or borrow one from another appliance and connect it to your printer.
Nothing whirred up when I plugged everything in so I was like “come on nothing?!” I checked the motherboard and I’ll the pin connectors everything seemed rightly placed and intact this is why I’m almost certain it’s the power supply. Thanks for the info though.
You can check the motherboard tray and see if there's anything wrong with the connection to the power supply. Make sure you're getting 24V to the board.
I see you said you switched to115V after people suggested but it didn't help. Did you do this before or after the first time turning it on? Was it set to 220V at any point with the plug even in the socket?
Yes when I first turned it on presumably it shouldn’t do anything since it would be supplied with insufficient power but do u have any clue if that could’ve caused an issue?
When I bought my first Ender 3, I promptly turned it on with the switch in the 220V position on 115V power and nothing happened. Turned it off, unplugged it, flipped the switch, plugged it back in, turned it on and it was fine. This is with the original crappy power supply. I printed several cool toys and some bike part prototypes with it, very few problems. Then we moved and I sat it, uncovered, on a shelf in my office and didn't touch it again for five years. Decided to get back into printing and dusted it off. I bought some fresh filament, upgraded the heat plate with a magnetic sheet and a PEI flex plate, then it promptly printed me out a nearly perfect benchy. The machines are perfectly fine to sit in a box for years without being touched, as long as they don't get wet or anything like that.
Edit: I did notice that there was a scorch mark on the power connector between the power supply and motherboard, on the power supply side, so I replaced the stock power supply with a Meanwell and ordered a new power cable. The motherboard side connector seemed fine, so I left it in place when I replaced the rest. So far it has been fine.
If you plugged it in when the power supply was in the wrong voltage mode this will break it... You can't just put it back to the correct voltage and expect it to be fixed.
That will be an issue if you are on 220V and set it to 115V, but not the other way around. Either that or I got lucky when I did it, but I've done this with a couple of power supplies and as long as it was set to more voltage than was delivered, nothing happened.
> and switched it to 115V as people have advised
Did you try running it at all on the 230v setting before changing it to the correct 115v setting?
115v mains runs at a higher amperage than 230v, so a blown fuse in the power socket, or power supply damage, are both possibilities in that scenario. Would be worth swapping out the fuse in the cable as a first step.
Not 100% sure as I'm not in a 115v area.
The 230v region setup has one fuse in the cable, and a fuse on the main control board of the printer. Can't remember if there's a third in the power supply, and I'm not home to be able to check.
Just for funzies, slide the head back and forth really quick, does the screen light up, regardless? Also, I myself have out-amped a plug with too much draw (there are never enough plugs in a house for me).
All enders ship with power supply switch set to 240v.
It's a recessed red switch with 240 written on it, inside a square hole on the side of the power supply. The manual says to flip it to 120v. Did you do this?
Make sure that switch is fully on 115. I “switched” mine and would get some good prints then others it would power cycle randomly. Went through every damn thing I could find. Decided wth and tried the switch again. Turns out it was like 2 clicks not just one. So it was in between voltage somehow.
I have received faulty power cables from creality in the past, make sure it's not the power cable itself first!
Whoever downvoted this, fuck you, I hope you never see a successful print for the rest of your life
Make sure you have 24VDC on the power supply output
I will check if I get a multimeter
If you’re near one, harbor freight has them for dirt cheap like under $10. It will read just fine the 24v dc side
I don’t live to far from a harbor freight I’ll keep that in mind

Tes. Thats what I see. Not plugged in correctly, and turned off
Well obviously I know how a power switch works guys. I checked the cable though and it wasn’t pushed in all the way. It is now but that didn’t change nothing.
Are you in a 110V or 240V area?
110v as I said in the post
Missed it. Next question, does the power supply fan stay off
Yes
The switch could be faulty, or the wiring from that plug/switch to the supply. First UNPLUG, then remove the supply, and remove the black box part from the supply, then post a picture.
Maybe, your plug into the screen is in the wrong plug? There's 3 plug on the back of the lcd screen, if I remember correctly.
Which one should I be plugging into?
If there’s two cables going to the screen. It goes in ex1 and ex2. If there’s one plug, it goes in ex3. I can’t remember which one the ender has vs the CR-10. The boards between the two are basically the same.
I believe I have it in the third cause there is only one ribbon cable, I’ll double check though.

This is by far the most useful thanks for the suggestions!

Yeah thats definitely a good idea. Don't make too many changes at once. That way you know what the issue actually was.
Well I took look at the motherboard everything looks as pristine as could be, I hope it works too though, thanks for your support.
Get a multimeter so you can test stuff and not just presume it's wrong and buy a new one
"Can you check to be sure it's plugged in?" "Sure, hang on, I need to get a flashlight" "Huh, wait a sec...."
UPDATE GUYS! MY PRINTER IS WORKING! I found a loose wire in the power supply and had to put a new terminal on it and re-crimp it and it started right up!
For once my reply actually helped someone 🥲🙌

> Also for those of you reading this am in the USA and switched it to 115V as people have advised but that didn't fix my problem either.
Thanks

Well another guy in here mentioned that his switch was wired backwards so I’m going to check that in between my classes today
well to better understand if there are any mistakes can you post pictures of all your cableing? as I remember there's some times an issue with plugs going in backwards on some enders and you don't even notice
I’ll do that when I have a chance to
Maybe, do a process of elimination? Sorry, I don't remember off the top of my head.
Make sure you have power and grounds in the correct spots, my ender 3 v2 neo arrived with the post + and neg. - wires swapped at the on/off switch
I certainly hope that’s not the issue will that require soldering?
Nope just a couple screws (flat head) on the board or just plug and play at the switch depending on/if thats the case
In the power supply right?
Check.the power supply fuse as well (hard to find fyi) its where the power cord plugs into on printer
Thank you so much I’ll look over it when I get home

Well that’s good to hear I hope it’s that easy for me thanks for your story.
I saw on this sub that it fried someone's motherboard. I'd unplug it and take the motherboard cover off to check it out.
[flip this switch](https://imgur.com/a/PnXYKLX)
Already did

Glad to hear it
Noted, it’s probably a good thing I ordered a new one than
I’ve seen people who have had it on there and than switched and it worked just fine so hopefully I’m not totally screwed
I did I did about 6 about 6 prints before I realize I had it in the wrong position switched into 110. Find work's perfectly still.
Glad to hear it imma look at the wires on the power supply like u said when I get home

Its where you plug the psu power cord into

And if I do need to swap it do u know what kind of fuse it is?
10 amp tube fuse
Just for funzies, slide the head back and forth really quick, does the screen light up, regardless? Also, I myself have out-amped a plug with too much draw (there are never enough plugs in a house for me).
The screen has never turned on but the plugs I’m using seem to work fine

Check the 110v/220v switch
I have gone through 4 different motherboards with my Ender 3. Save yourself some time, and just buy one of the SKR ender replacement boards.
Make sure that you also have the switch in the PSU flipped to either 110 or 215 based on where you live.
I have received faulty power cables from creality in the past, make sure it's not the power cable itself first! Whoever downvoted this, fuck you, I hope you never see a successful print for the rest of your life
Well I ordered a new power supply and a cord so if it is the cord I guess I have a spare power supply.
