Flickering screen hardware or software?
The screen was intermittently flickering and gradually died on me. I replaced the magsafe (and thunderbolt) cables within the system with your guidance. Now it does not seem to die on me anymore, and the flickering changed to random short flickering (one or two times short). Do you think i still have a hardware issue or is it a software issue (all software up to date, incl the firmware of the thunderbolt display), done SMC and NVRAM resets, etc. If it is a hardware issue, what can i still replace (logic board)?
THIS IS EXAMPLE
