Can I swap a LCD from a 27" 2009 iMac into a 27" thunderbolt display?

The LCD on my 27" thunderbolt display (LM270WQ1) burnt out about a year ago.

I haven't had the time to repair it and Apple told me it would be ~$600 to repair if they did it (of course).

However, on the 27" Thunderbolt display tear-down here on iFixit it shows that the 2009-2011 27" iMacs use the same display (LM270WQ1) but a different sub-model.

I've found a few of those displays on eBay, but before I pull the trigger I want to make sure Apple didn't do some stupid $@$* like change the ports so you can't do what I intend to. Unfortunately, Apple themselves won't answer the question despite discontinuing the product all together.

回答此问题我也有这个问题

这是一个好问题吗？

You can change the panel display from the LM270WQ1 SD B3 to any version.

You’ll need to change the backlight cable from the right to the left. The most important is the T-CON board LM270WQ1 SD B3, replacing SD A2 T-CON board.

i’m so very happy

For the LM270WQ1, set for only 2009-2011 for use with the Thunderbolt Display and the most important you have a T-CON board SD B3

I would be very hesitant - Even the iMac has different connections going to the board, from that display in that range of years.

Would be very surprised if they were compatible - Would be very unlike for Apple

Sorry, no. The connectors are slightly different and therefore will not function if swapped. It’s pretty typical of Apple to do this and after coming to this conclusion I was not surprised. However, if you do want a replacement LCD that will work with your Thunderbolt Display you can buy one from eBay at the link below.

@ajcooke01 is this different than the other from one year ago? Are you adding any different information to this?

@oldturkey03 Not intending to make it look alike but I see what you mean now. I did my homework and researched it up though. I also gave a definant no too, so I kinda switched it up but not by too much.

@ajcooke01 so are you adding any different information to this? This looks like a duplicate answer. Even a definite No is still only a comment at best

@oldturkey03 Eh, not really.

@ajcooke01 may be I am just to old to see where your answer is different. Care to point out where you are adding information to this.
