This was very helpful. Was quoted $180 plus tax to get it fixed and after finding your video, I purchased the part for $22 on eBay and installed it myself. Thank you very much for sharing.

@@GRIBSOFT great video, but how do i know if this is my problem? i have this model imac and i powered it off, unplugged it for 8 hours and now it has no life and won't turn on at all
Excellent video. I followed it just now to replace the power supply on a 2011 21.5” model. Worked like a charm. The data connector on the 2011 model screen is smaller and more fiddly than the one in the clip but the idea and procedure is the same. $50 for a used power supply on eBay, $7 for the suction cups for the screen, the torx drivers I already had, a lot cheaper than a replacement computer.
Bro! Thank you so very much. I greatly appreciate your video. I was so nervous personally about being able to replace my power supply in my iMac when it just started powering my iMac down. Once I acquired all the tools and part, I found your video which is literally the most helpful and easiest tutorial to follow and my iMac is back up and running! THANK YOU SO VERY MUCH. I cannot express how thankful I am!
The best tutorial of how to replace a power supply, thank you
+Aby Hamouda you're welcome :)
Thank you for the tutorial!
I followed step by step your instructions and everything went perfectly
Great video! It’s also sorta calming you sound like Corey Feldman
this is legit the best tutorial that actually helps i've been searching for multiple but only managed to get the lcd off with what i hope is minimal damage to where a wire connects but if only I had found your video first it seriously makes things so much clearer thanks :D this will certainly help me.

Must be a lot of different iMacs in those years. My 2010 was a lot different inside than this one. Two of the large ribbon cables could not be disconnected from the screen side. I had to work around the screen to get to the power supply.
thank you
very good demo
Helped me a lot, thank you very much!
Great video! Thank you so much!
Thanks for the comment
@@GRIBSOFT No worries! It was a great video. My mid 2011 27" keeps restarting and I think it's the PSU so your Video was just a great education! Thanks again!
Why need replacement de power supply (porque se necesita sustituir la fuente depoder en la imac?)
Where can I buy this power supply please
Hi! Thank you for this video. I have imac 2011 27 inches. serial no. C02GY2ENDHJQ EMC No. 2429. I didn't found power supply for this in India. Can you please guide, where can I found this online?
I’ve always heard that you shouldn’t touch the front of the power supply where all the connections are soldered to avoid shock. Is that true? Or will you only get shocked if you start messing around with the capacitors?
I see on the video you grab it without Rubber gloves and touch the front side of the power supply unit.
Sorry for the late reply, but the reason he did touch it was because he had the iMac unplugged. He states the caution at 1:40. Cheers.
@@charlie1361 it will still shock you
@@piggybackbuyer2329 this shocked you without being plugged in? What did you touch that you were shocked? Thanks
Thank you!!! clear and easy!

I am debating if i need to change the power supply on my mid 2011. It stopped powering on. I opened it up and have the Led indicator #4 is on. But #1,2&3 are off. I can hear a buzz from the power supply but nothing else is on. I cannot hear the hard drive spin. Any suggestions? Would it be power supply if that #4 led is on?
Did you ever figure out what was wrong with your imac?
I'mstill alive no still dead, i was wrong with which led was on. Its number 1. But still do not know whats wrong
Im in the same boat. I have already bought a new imac at this point. I was just trying to figure out if i should spend the extra money to attempt to fix this imac. I know before my power supply went out i was also getting a black screen so i feel like it's a lost cause at this point. Ready to pull out the hard drive and dump the whole thing.
Muito bom seu video
Obrigado!
What brand of power supply would you recommend? I've heard the 'Lite-On' make recommended for 17" iMacs but I haven't seen any for the 21.5. If you get a chance to answer it would be much appreciated.
My mid 2011 won't turn on... when I press the power button, I hear the CD drive trying to eject or something, but never hear the startup tone. The screen is black. Does that sound like the power supply? If I plug in a USB mouse, the red light will come on but there is the hard drive never starts and the display is black
The LCD is the first thing to replace, then try the graphics card next.
Thank you for your well infomred video. I will apprecaite if you or
anyone in your forum could tell me what is happening to my Imac mid 2011
27 inch not coming on. The stand-by LED light on the boards comes on
and goes off immdiately when I insert the power cable. It is not stable
for me to press the switch botton . So is the problem with my power
board of the logic board. I need your urgent response for me to know
what to buy as replacement
You need a new power supply
@@GRIBSOFT many thanks for your prompt rsponse. Is there no way or advice or link you can share to troubleshoot the problem with the pow
er supply in the view to fix it rather than buying a new one
@@GRIBSOFT Hi, Thanks for the advice. I just change my power supply . unfortunately my imac did not come on. it was behaving the way it was before changeing it. that is the first led standby light on the logic board showing green was not stable when you put the plug in. It goes off and on rather than it to be stable. immediatly I press the switch nothing happens and the led light will stop flicking. After a while when I remove the plug and repeat the processm the led light will continue to flickers rather than being stable. What else could be responsible please. Just to note also,When I tested mypoert supply with meter, the input voltage was 240 but there was no output voltage to signify that a supply is going on to the board
hi Thank you for the video. I've got a dead iMac 21", bought a pair of suction tools and the power supply, and pulled out the screen. But soon encountered a problem around 33 sec of your movie: after successfully pulling up the top two cover, I cannot even unplug the lower part of the screen! I don't know what's going on, but it seems that the lower magenet or something got in the way to prevent me from pulling it out. Not sure how to proceed. Any suggestions? many thx!
Una consulta tengo la misma iMac le estaba haciendo mantenimiento y luego de ensamblarla emitía 3 pitidos instalé la memoria y luego solo 1 pitido después no quizo encender más quedo como si no tuviera corriente
Hi! Good video. My iMac 2009, is totally dead, no sounds or lights when pushing the start button.
I've accessed the PSU. AC power is going in. The mother board LED 1 lights up (when the AC power is connected to the iMac).
DC out put (COM is 1) - No 2, 7, 8, 9 indicates 12V,
No 3, 4, 5, 6, 10 has Zero Volts.
Is this the PSU or something else? Appreciate your export opinion. Thank you
Do you know how to check if the power supply is what needs replacing? Thsnks
Only trial and error.
@@GRIBSOFT can you write a basic description of how to determine the power supply is the problem? that is what this video is missing at the beginning
thanks
@@TheJstringer Also, what's the correct power supply?, what are the specs? is it upgradeable to a 310w? Why or why not?
Hi, thanks for posting the helpful videos. For the past couple of months my imac had an issue, it would shut down suddenly after 15 mins sometimes 10 or 5 mins, until it stopped working at all (no power whatsoever). I ordered a used power supply online because i assumed that if there's no power, it must be the power supply. I replaced it and still no power(no sound, light or fan) nothing. I'm not sure if the power supply that i bought was not functioning or the cause is something else. I also don't know how to test a functionality of a power supply with a multimeter. Any advise would be much appreciated. Thank you
1 Power supply, 2 Graphics Card, 3 Logic Board. Replace in that order.
Can you help with the name of the tools used for removing the screws
Screwdriver
Nice simple video! I have a 2009 iMac 27, suddenly today it will just not turn on (no sounds, no beeps, no fans, no response at all). We just had a power outage during a storm and I'm not certain if i need a power supply or the main board... (it is plugged into a $50 surge protector). My only clue that i might need the main board is because one diagnostic green light is on when plugged in (looking from underneath on the inside) which indicates power supply is getting power right? how can i tell??
It's the power supply.
@@GRIBSOFT even if the green diagnostic light is illuminated?
I'd hate to spend the money on a hunch
@@GRIBSOFT What does the green diagnostic light indicate (on the main board)
I have 1,2,3 led lights on. On start up I hear the initial click but no chime. Black screen. Fan runs normally. Could Power Supply work partially to trick me it's something else wrong?
My 2009 iMac shut off with no reasons. When i try to turn it on, it makes the classic "dong" sound but the screen remains black. All te USB ports has no power but the imac still run. It could be the power supply?
Yup I got shocked
Please follow the warning signs, it put that in for a very important reason.
I need help about old "Early 2009 24 A1225 Imac" Display! Can i replace a LM240WU2(SL)(B4) with another LM240WU2(SL)(B2) Display? Could someone help me please?
I’m having an issue with my 2011 iMac. I recently dismantled it to clean the 9 years of dust that had accumulated inside the fans etc. When I put it back together the screen is now flickering when I turn it on. It was working 100% fine before this. I did remove the power supply unit too when dusting. Power supply unit my issue?
follow, my screen is flickering as well. Is your screen flickering like the brightness varies. (so not like on and off)
ACMDE changed my power supply. Working 100% again now
my imac was shutdown after a sudden electric power shutdown. now it's not turned ON anymore. Do you think the problem is with its power supply?
That's where I would start.
Good day I would like to ask if you have some idea, I buy 21.5 iMac in japan they use 100 volt.. can I use my Mac in Philippines which using 220 volts?
It should do. I'm in the UK. My 2007 iMac has a power supply that operates across 100V-240V @50Hz-60Hz. Apple uses universal power supplies to simplify their production processes.
Don't you want to test it first before installing screen
My iMac 21 don't start at all. I press the button, but nothing appens. Can it be due at power supply?
Regards
Paulo Ramos same, did you get it fixed?
@@idantal1213 Yes, after dismount it all and clean the supply power. I also changed the power cable for another.
it is any way to adapt to this iMac a card with USB3...÷Thank you.
Sure! There is a thunderbolt adapter for USB 3.0 and eSATA in one here: amzn.to/2MPXf1W
Wait we have to buy a new battery
No battery needed.
Hey is on???
Is there anyway to test the power supply?
On older imac there were light indicators. I wouldn't test the power supply with minimal knowledge as it is live at has AC current going through it. Your best bet is to just purchase another power supply used.
Save Apple Dollars That's what I was planning to do.
The list of parts that usually break in this model go as follows: Power Supply, LCD Unit, Inverter, Graphics Card, Logic Board. I would start with the power supply and move to the inverter next as they go for less then $20. Good luck.
thank you
