hi, i have busted screen on my iMac. replacement will cost around 700GBP, i will not pay that. i have been looking for replacement screen, which should be Lm240WU2-SLA1, price for them is still too high, not mentioning their very limited supply. i have found some cheap screens, stating LM240WU4-SLA1. going for 60GBP free p&p in my area, do you think this would do as a replacement? looking at the picture, i cannot really say the difference, can anyone here clarify for me? thank you Update Im not home yet, that’s why I cannot give you serial number. But it is the last White 24" iMac with intel processor before they turned to alluminium. And about the screen, I am as sure about the part number as I can, as I was writing down the part number off the actuall busted screen… Never mind, I think I will be on a hunt for working screen for one more month, after that the machine is going back on eBay. Thanks for clarification guys, it’s much appreciated. Good day to everyone…
No the will not interchange. Everything looks promising in the LVDS pinout until you hit pin 25. Pins 25 - 28 are used for different purposes on each monitor. The data sheets are here for the U4 and here for the U2. My understanding is you can replace your LM240WU2-SLA1 with the LM240WU2-SLB2. The differences between the 2 LCDs being the A1 is matte and the B2 is glossy. Here is a reference to someone successfully using the LM240WU2-SLB2 in their iMac that originally came with the LM240WU2-SLA1.
