You have to put the boardview file inside a zip archive to be able to upload it.

First of all thank you very much!
Im new to the crew and no expert in electronics repar but have a sense for it and technical background knowledge. Im from Germany so please excuse my english.If you have any questions, go for it!
I wanted to ask you guys for help with my Imac .
Is there any possibility to get brd file and schematics for 820-00291-a?
I upgraded my late 2015 imac 27" Retina 5K i5 3.2Ghz with 16gb ram and a 1tb nvme ssd recently. After i re-assembled it i got no start chime and no display! diagnose LED 1 and 2 are on but no 3 and 4,
maybe some of you guys have a tip for me what i can do. I already checked some voltages and caps for short but i only found out
My first thought was that the nvme or ram was not ok but after installing the old ones same problem.

Me again,
i managed to find the issue that caused my problem. Just in case anyone wants to know: I accidentially broke on pin on the cpu socket that connencts to the ram slots "A". I just installed the Ram in the B slots and everything works fine again. Thanks for your support.
