Hi guys! Display doesn’t work in my iMac 2017. I already replaced LVSD cable. It didn’t help. Can it be cause of the problem?(see picture)
Yes! it does look like some moisture damage and the components have fallen off. I don’t have a schematic and boardview for this system so I can’t tell you what you’ll need to get to replace the damaged components. Update (04/14/2019) Are you able to get an external monitor to work?
Hi @ruslansolovka did you figure out what the problem of your iMac was? In fact no components seem to be missing on your board (at least not within the provided image section). Just for comparison I added a picture of my (fully working) A1418 2017 4k iMac of the exact same location. Pleas note, that not all of the ‘stain’ is due to water damage - but I would recommend taking a closer look at the tiny capacitors of the upper circle as well as the same section on the other side of the board
Best
