Repeated boot chime and no display
Earlier I had this Artifacts on screen, not sure if LVDS cable loose or GPU issue. I resolved it and MBP was working fine, but now suddenly it won’t boot. I am hearing repeated boot chimes indefinitely and nothing on screen. When it was working I noticed that left shift, 7,8 &9 keys were not working.
I tried to reset SMC & PRAM but not sure if it works(as the left shift wasn’t working earlier). Sometimes it boots with no chime and nothing on display.
I did face this issue when I was trying to solve the Artifacts on screen, not sure if LVDS cable loose or GPU issue issue . Somehow I surpassed it and was able to boot into linux. But I don’t remember what exactly I did.
Is dit een goede vraag?
