description of the display and part number

Hi guys,

I am looking for a new Display because mine is faulty.

My question is now which one can I use?

LM215WF3 SD A1 ?

Or also another one?

LM215WF3 SL A1 LM215WF3 S B1 and so on?

And is there a possibility to check the display itself without testing it on my iMac?

Beacuse Iam not sure if it the connector or the Mainboard.

By the way: Display is black an external is working, 4th led off

Thank you very much for help!

Frankly I'd replace the backlight board first as it's cheaper. Apple part #661-5537.

LED #4

Indicates that the computer and the LCD display panel are communicating. This LED will be ON when the computer is turned on and video signal is being generated. If the LED is ON and there is no image on the LCD display panel, the LCD display panel or inverter might be installed incorrectly or need replacement.

Hi, thanks for your help.

But here is my next question which EEE code on the Backlight board referees

to which on the LCD screen?

Is it right?

EEE of Backlight : GDX

EEE of LCD : GT3 ?

I bought the iMac faulty on ebay, so I don't know if it the right backlight board.

May the person who owned it before bought a wrong one.

I appreciate this is an old thread, but I'd like to try to find some clarity on the LCD part numbers. For this model are these 2 interchangeable?

LM215WF3 SD A1 or LM215WF3 SD B1

I have been hunting SD A1 for a long time (on a budget), and have since realised that the B1 might actually be compatible too, which ups my chances of finding a cheap one on ebay.

Please could you clarify if this is the case?

I've got as far as seeing it's the same year, dimensions, the cable is the same part number for both of them, also one shop is listing them alongside each other as one and the same. But I haven't had absolute confirmation from someone who knows!

best wishes

Hey did you find that LM215WF3 SD A1 / LM215WF3 SD B1 are the same/compatible? im looking for a B1 but its easier to find an A1 on ebay/amazon

I think they are interchangeable, but I didn't find an absolute definite source. I decided I was prepared to risk it but in the end I found an A1 anyway so couldn't test.

They are the same year and model, I think it should be fine. I find it hard to imagine why they wouldn't be compatible considering this.
