good morning everyone. I have a problem with my iMac. unfortunately the screen starts to look with horizontal stripes. after verifying that it is not by the graphics card, I bought a led a different model and some connectors are different. He led riding my iMac is lm215wf3 (sl) (a1) and I bought by mistake lm215wf3 (sd) (a1). several problems. the temperature sensor input is different, and led backlightsync also is different.
