Red lines on startup
Hi. To explain the best. The laptop had a GPU problem. So I changed Logic board. Also I changed RAM And HDD to a ssd. Worked fine for a week.. And Then red lines. Never had that problem. Comes to the loading Apple logo. And Then turn dark Grey without the red lines. It wont Boot to safe mode, recovery mode or diagnostics.
Tried resetting SMC And everything.
I havent tried a external monitor. It wont do any diagnostics When i Boot it up.. on the normal screen
Is this a good question?
