iMac Logic Board Replacement 2009 2010 2011 21 5" Apple Dollars #11 

Super good! One of the best I-Mac tutorials ever! I agree It is better than iFixit. You got it down and done right! Thank you very much! Got any ideas about CUP replacement for Imac 21.5 Mid 2010?

I have been fixing Windows based laptops and MacBook Pros for a few years but never tackled an iMac. I picked up an 09 for 75 bucks and followed your great video. I found a logic board for 49 bucks. Took my time and everything works fantastic. Thank you for your great instructions.

My 21.5 mid 2011 iMac went completely dead and would not power up at all. I took it to the Apple store and was told it might be the power supply. As it turned out, they told me the logic board is bad and would cost $650.00 to replace. I found a replacement board for $30.00, followed your video instructions and just wanted to say thanks. Great directions that saved me a ton of money. Best tutorial I've seen!

This is the best tutorial a ever seen about imac 2011

Once again, you are the man! I am so thankful to you for labeling everything and disassembling everything and reassembling it with great instructions!

This is great! Thank you very much for doing this. All the extra graphic tips are a big help. Changed out my logic board properly, thanks to you.

This is top tier content. One of the most helpful videos I've seen on RU-vid. Thanks so much!

Thanks for your video. I successfully replaced the logic board. I recommend attaching stickers to wires and labeling or taking photos so it’s easy to put back in reverse. I drew a schematic for the screws and this sped everything up. I had to look at photos because I also forgot what side logic board went and what order screen and frame go on.

Thanks for helping me with mine. Picked up a 2011 27 inch iMac for free with broken ram slots. Now I feel more confident about approaching it.

Amazing video man, i'm saving this one for later and I can't help but check out more of your content! Thank you so much.

This is awesome! Thank you very much! One of the best iMac tutorial I've seen. I was bout to change my logic board battery. It's not saving time anymore... Too much to go trough though. Hahahah.. I'll just leave it plugged in. I use this to write a lot of script and as my backup unit. I have a newer one. I just felt like this will still work on simple stuff.

Very clear and concise video which I will be using to replace the logic board on my 27” iMac. Broke off some prongs on the video display port therefore the need to replace the board. Thank you.

Thanks a lot, is really going to help me instal a new logic board in my son's Imac!

Our 2011 iMac would not start up so we took it to a reputable Mac shop. Apple repair shop diagnosed bad logic board. They tried a new video card in the shop and that did not work. So, we personally ordered a new logic board online and installed it by following your EXCELLENt video. The main thing different about our computer was a big metal flag-shaped part that we transferred to the new logic board (the silver "flag" portion was just above the CD ROM drive.) We also had two more cables than you to connect on the back side of the logic board. Now, we can hear the proper start-up tone but the screen remains black and then the fan kicks on within a minute. We are able to press esc. on the keyboard and it beeps and we can control the volume of that beep via volume controls on keyboard. Seems like we have made progress since the startup sound did not previously occur before we installed the new logic board. We tried safe boot and the response was the same as noted above. Any chance we just didn't hook up the screen properly? Suggestions? We want to keep this computer because we put a solid state drive in this year as well as additional RAM. It has also had video card replaced in the past. thank you

Thanks for the simple and easy to follow video! SEEKING ADVICE! I found a late 2009 iMac 21" at the recycling center in my town. I originally just wanted the RAM cards from it, considering I do not know how to repair computers at all. When I got it home, I tried starting it up, but I got nothing. Although it didn't rain, there was probably some condensation/water damage that occurred. Did a few google searches and went down that rabbit hole. One LED diagnostic light remains on. I removed the logic board thanks to this video, and the coin battery on the back does seem a bit corroded. I'm thinking the slight corrosion on the coin battery is an indication of other areas that may be damaged. And say I go ahead, and order a new logic board, I'm not even sure if that was the problem in the first place. It was fun to pull this apart and learn a bit, but the RAM cards is enough of a victory for me. It's just seems like such a shame to throw away such a beautiful looking iMac. Asking this question is really my final attempt at wondering if I should dive any deeper here, but does anyone have an idea if this is a logic board issue, or if I should just chuck this and save the RAM??

Thanks mate. Great video. I used this to put an imac back together after baking the video card and it works like a dream. Cheers

Excellent instructive video, well articulated and executed... helped me to repair my imac. Many thanks.

great video man bring it on!

Yes I agree, very well done. Much appreciated. Thank you. Very professionally done!

Hi very good video. It is clear as to you know what you are doing. Can you please make a video about the entire wire connections of imac 2011, 21.5''?

AWSOME!!!! BEST TUTORIAL!!! THANK YOU BROTHER!!!!

You saved me 500 dollars.. thanks!!

Helped a lot!

Many thanks for a very helpful video. You did a fantastic job on the step by step removal and replacement. You saved me from many mistakes. Thanks again!!

The true Wayne is that watching at your tutorial becomes very easy to follow, since you described, basically every cable by its own name, I could figure it out what my problem could be, as you mentioned different sensors that works to control temperature. My case started today with a big noise in the fan located behind the logic board, before to listen those fans, you had to get very close to the computer, now I can hear it from every where, at the same time the bluetooth card stops working, this two events at the same time makes me wonder if there is a temperature sensor damaged, so to find out witch one is the one with the problem, I'm planning to change them all ( if I'm able to find them). I'll post my experience when I finished with the job to let you know how did it goes using your guidance. Thank you for your excellent work!

Thanks great video dude

Very well done -- thanks a lot.

I love the ad,its great.

If my mid-2009 iMac came with a 2.26ghz logic board, can I get a 3.06ghz logic board to use instead?

Excellent Thank You!

Awesome Tutorial. Is this the same method for the 27” of the same year? Thanks

very good

You have a like and sub. This info was invaluable to me. Thank you for doing such a great job.

So do I have to pull out the memory before taking off the glass and LCD Screen?

So I have a question my 2010 Imac model keeps shutting down. I notices that when I try to load a game up it take forever and when it starts to play the hole iMac shuts down. I’m wondering if the thermal paste dried out. Any idea thx

Thanks for making this video! Do you know about the "video card pressure wall" and could you describe where it should be positioned? While removing the logic board from my iMac (mid-2010 21.5" A1311 model) in order to replace the backup battery, the small, black plastic part fell out. I haven't been able to work out where it goes. It's made of the same black plastic as the power supply pressure wall but much smaller with just one screw hole. The Apple Technician Guide mentions it in the list of instructions for installing a new logic board. However, it doesn't show where the part should be positioned.

best . tutorials thank you

Nice brother

This is an excellent video.I replaced my PRAM battery,put it back together,everything works fine EXCEPT my BLUETOOTH isnt working.The I con for bluetooth has a horizontal line crossing it out.Any suggestions?

hello. great video. i have a 2011 27" Imac. It was beach-balling constantly and now crashes mid way through start up and turns off. Do you think a new logic board would help me?

I know it may be old, but I have a 27" iMac emc 2390. It's had purple/green squares on the screen for a few years, but for some reason the fan kicked it in at full speed and ran fine for a few weeks. Now I think the fan died and it seems like it overheats and has obvious graphics card issues. Any idea what the best fix for that would be? Will be reading through the comments, but I just watched a bunch of CompTIA A+ videos and want to see if it's fixable. It worked great for years, and I now have a tool kit for this. Just figuring out what I need to do before attempting it.

Is this similar for an early 2008 imac 24" ?

currently, I have late 2009 iMac 27"... Can I upgrade with the newest logic board (2011)?

thank you

I have a imac 27 i7 mid 2011. Producing electrical buzz noise. Had psu swapped to no avail. Still buzzing. Please can you help?.

I'm told the connectors for a 2nd HD/SSD are on the back of the motherboard. Where can I find those? I'm installing a 2.5" HD (with 2.5" to 3.5" adapter bracket, installed where the original HD would be), & an SSD as my boot drive installed directly underneath it. (Rather than restricting airflow past the DVD drive & GPU.) I imagine I'll need to put the temperature sensor on the 2.5" HD. Where do I put the electrostatic pad, in this config?

Hi Bud have you a teardown for the 27" version?????

Could this help fix sound issues? My imac has no sound whatsoever. I've tried everything, even the headphone plug in and out trick.

Hi mate i am trying to reassemble my iMac late 2011 logic board and this cable fell off from back of the logic board , i dont knkw where it goes i know one end of it connects to back og the logic board but whrre does the other connectir go ? Can ypu please help ?

Can iMac 2011 21 motherboard really fit on 2010 21 Chassis? Or I have to make some change? Or it just plug n play?

How can i check which motherboard i shud bye for my imac?

I replaced a new logicboard, but I don't get power anymore.... I checked the power button cable, and it's connected... Is there a way to test it outside of the chassis? can I test the power functionality without connecting the LCD?

Will this allow to get around a locked apple I'd logicboard?

What is the board next to the Hard Drive called (on the left side)? Thank You.

This is a good video.

This is going to save me $500!!! Woohoo!

Thanks

Also can anyone reccomend a place online where I can buy a new screen(just the glass) for the 2011 27" Imac?

Hello. Right now I'm looking for an imac to work with text, pixelmator web browsing and 720p youtube viewing. Will HD 4670 and 16 ram card handle this? Purchase for 2-3 years. Tell me, is the 4670 card very hot? I need a job 12 hours a day. Does the card burn fast like the 2011 or can the 4670 card in the 2010 model (256) be used for a long time? Thank you

Can i put 3GZ processor in imac 9.1 2009?

Is it possible to replace a late 2009 Imac 21 inch logic board with one from a later model say a 2011. I inadvertently damaged the display port on the logic board during a hard drive upgrade. System still works fine with an exterior monitor but looking for options to get the built in screen back.

Awesome video. Unfortunately, I decided to replace the pram battery and the holder became disconnected on one end. Any thoughts on how I reconnect it? Thx

Anyone know how to take the gpu off? I don't know what to do with those shiny black topped screws. Turn them or push them or just pry it off? Little help please thanks....

One simple safety measure, that nobody shows on these videos, is to take a small pillow and stuff it underneath the monitor so it's jammed against the stand and the back side of the monitor.........this tilts the monitor back, so it can't drop forward when you're removing the screen. If the screen drops forward it will yank all of the cables out from their connectors, and your imac is toast! Oh yeah, and if you're gonna attempt to disassemble one of these machines, after removing the power lead you should push and hold the power button for at least a minute, so the power capacitors drain any residual charge. You should also wear tight fitting surgical gloves and an anti static wrist band to prevent any potential damage to the components. This is all basic stuff that nobody ever mentions.....just my two cents.

Nice video guys! Are the logic boards on the three models (2009-2010-2011) interchangeable? Can I put a 2011 logic board in in a 2010 model?

very well

Will this be the same method used to replace a 2010 iMac 27" quad core I-5?

hello, is it possible to upgrade my 2011 iMac i5 board to a i7 quad core board ? also can i upgrade to an SSD instead ? thank you

Thank you guys for the very detailed tutorial! Question: can I replace the logic board of my mid 2010 iMac with one from mid 2011? I want to run quad core i7 and my mid 2010 can't do that due to TDP limitations.

how do i fix a wire that was damaged when being pulled out, (the little box seperated from the wire, one end of the wire is still inside the other has slipped out clean the little one @ 5:25).

Great tutorial I have a late 2012 iMac whose SD reader is not working. Is it the same procedure? thank you!

Hey quick question my I mac won't turn on at all took it to a shop they replaced the power supply board and that didn't work. I pulled my imac from the shop to repair it myself. I'm thinking it's the video card, what do you think? Or logic board?

Hi- I found a 2008 Imac in a dumpster and plugged it in and the screen flashed on and then flashed right off again. It's barely even scratched other than that. It;s got bluetooth keyboard and mouse with the original box. Do you think it's worth trying to save? What would cause it to flash on and then off again. Power supply. Thanks for the great video!

My 2010 iMac mic port is at the bottom of the motherboard by the fan I’m confused lol

Help! I have a A1311 2009. Power checks on logistic board. Pin 4 12v Pin 11 gets 12v when I hit the power button but no LED 2 light. Also no signal power on pin 12 when I press the power button. What and how do you take measurements of a signal power?? Disconnected all plugs one at a time. No fix. Also what is that battery on the logistics board? Can that be dead. What is its purpose? Thanks!

Hi. I have a macbook pro mid 2012 13" core i5 that was recently water damaged. I decided to send to iStore to repair it but finally they told me that I need to get another logic board with model number A1278, The question is how much risk exist if I swap my logic board i5 to logic board i7 13" 2012 mid, both are the same model number A1278, Do you recommend doing this? Thank you!!

my imac has dead usb's, wifi, bluetooth connection. Do you have also a instruction to replace them ( not entire logic board)?

Can i put a 2011 in a mid 2009

Thanks for your video !!! it is great ! I´m trying to bring back to life my Imac 21.5" mid 2010 and I want to ask you please if I can change the LOGIC BOARD with an Imac 21.5 mid 2011 Logic board, because I was reading and this has LGA 1555 sockets and this will allow to make better upgrades for GPU, and CPU. Thanks =)

What is a reliable source to buy parts from? I'm considering buying a 2011 iMac but would also need to buy the part. Any recommendations?

How similar is the to replacing a 27" iMac logic board of the same years?

Hi Wayne. ¿Can you Healp me?. Mi Logicboard is dead and i cant find the replacement. iMac (21.5-inch, Mid 2011-A1311-MC812LE/A) - CPU Speed 2.7 - Quadcore I5. ¿Some Site-Seller to find it?. Thanks.

So is it possible to remove the SuperDrive and add an SSD in its place?

Hi. I ripped the vertical sync flex/ribbon cable. If I used the iMac without that, would that be ok or it'd damage the iMac? Also, when I power the iMac, there are fans and the hard disk spins but there's nothing on the screen and there's no chime. It's an 8 year old iMac. Will changing the PRAM battery make it boot again? I bought an Energizer CR2032 battery. Thank you. God bless, Proverbs 31

Has anyone done this recently and can offer any advice/tips? Believing I have the ability to reassemble at any moment is what I need to feel confident before taking it apart.

I took off the motherboard to replace the graphics card but when i put everything back together the screen doesn't turn on but the computer seems to be running. Which plug makes the screen work? Did I miss it, or did I just ruin my computer?

Hi , save apple dollars, I have another query, a 2010 , 21.5 inch , screen doesn’t turn on and there’s no chime, and only 1 led comes on, then I removed the graphics card, turn it on and 2nd led come on , I get startup chime and I can hear the Mac loading and running nicely ,(without screen) can you give your expert opinion please, cheers

Hi, I’ve followed your video, I’ve made everything like you, but now the computer doesn’t starts. I’ve tripled check the power source, it’s not that. It doesn’t receive any power, it doesn’t do nothing when I press the power button.

Could someone help me... My mac A1311 is not turning on. Led 1 power supply on, led 2 on, led 3 gpu on led 4 LCD off. Dvd start and stop. Cooler and speakers does not start. Flat cable (12pin) and connector power board x lcd ok.

hi,saveappledollars, my late 2009 27' iMac loads halfway on normal boot then stops , i performed all the resets changed the P-RAM battery , reinstalled Mac OS high Sierra , ran test on HDD which was fine, and it still won't boot up on normal start up,i then booted it up on safe mode and loaded fine ,screen is perfect everything works ,some help to resolve normal startup would be greatly appreciated, cheers

Hmmm big jump cut getting that logic board seated. Around 12:14. That’s hard to get back in. No one is showing this.

Hi, Do you know if a replacement logic board has to be the exact same processor speed? I have a 2.4ghz 24" MA878LL with a dead board, and i've found a board for the 3.06ghz 24" which has the same a1225 model number. Would this work? Thanks

looks like this model lacks an mxm based gnu I have a 21.5 inch model with a 3.06 ghz core 2 duo e series and a 9400m gnu I was hoping it had an mxm slot so I could install a radeon 6570 in it since I know the gpu on this board is integrated since its a Nvidia mcp79 chipset
