27" iMac Retina - Random Screen Flickering
Hi, I am experiencing the display screen randomly flickering on a 27” iMac 2015 model. I have upgraded the hard drive to 1TB SSD and was working fine until few weeks ago,
Have done SMC/PRAM reset, changed cord, changed power outlet, Apple Hardware test and no change.
- Wondering if anyone has experienced this and what could be causing it? I’m thinking could it be different memory I have added from 8GB to 16GB (4x4GB)?
- Or an internal display cable issue not sitting in 100% into the socket on the logic board?
Any thought’s much appreciated and I have attached a video of the issue.
