5K display assembly replacement
What is the display assembly part number?
Can it be replaced with older (2014/2015) models displays?
Yes the 2014-2015 panels and 2017 are different in terms of paper specifications (brightness) but they ACTUALLY CAN BE SWAPPED. I own a repair shop and we have swapped and tested them.
This is the model for the iMac 27” 2014-2015 display.
Installed in a iMac 27” 2017 as our customer wanted to use the older model as it is cheaper. Brightness control, Face Time camera, everything works.
Technical specs on paper is one thing, trying out the actual part is another.
There’s a reason why shop technicians don’t like to comment too much in iFixit. We are loaded with tons of customers. We don’t wish to be debating enthusiasts when we are trying to be helpful.
It would be risky to try until a parts listing is released.
Here is the Apple P/N 661-07323 - Mid 2017 iMac 27" Retina 5K LCD Panel & Front Glass Assembly
It can be gotten from TheBookYard in the UK 27" iMac Retina 5K LCD Display Assembly, Apple P/N 661-07323, LG Display # LM270QQ1 (SD)(C1)
Yes, but the 2017 LCD is brighter. I managed to find the actual model number instead of the useless Apple part number. The model is LM270QQ1 SDC1.
I do not think that displays from a 2014 or 2015 iMac will work on a 2017 iMac. They use different display panels all together. Your best option would be to either bring it into an Apple store and see what they quote you or buy a used 2017 27” iMac like yours and swap the screen on that. Apple usually charges around $600-$1200 for a screen replacement depending on how bad the damage is and the availability of parts at the time of replacement.
There are used displays for your iMac on eBay like this one: https://www.ebay.com/itm/184392127697?ep...
They are much cheaper than what Apple will quote you and they are not very hard to install. Check out iFixit’s guide and see for yourself: 2017年款27寸 iMac 显示屏更换
