After display issue re occured now the machine will not power up
In 2018 this machine developed a serious display issue. Horizontal stripes across the upper part of the desktop and the whole display image oscillating rapidly up and down.
The issue begins during the boot process. At some point the boot screen starts to oscillated. Then the login screen and desktop show the most interference.
It’s useful to note that the screen saver image is NOT affected.
After a real difficult process of trying to replace the logic board. Toward the last I reset the NVRAM and after the second replacement logic board would not show improvement
I replace the original logic board AND THE PROBLEM WAS GONE.
NOW, just yesterday the display issue reappeared. Resetting the NVRAM has not helped. Resetting the SMC also didn’t work. I could not boot into recovery mode or hardware test. (Yosemite is installed and is the operating system used to boot up).
To further complicate the issue NOW the machine will not power up. The power adapter plug status indicator shows Green.
Could this (not powering up) be an issue with the battery? I have replaced the battery once since I bought the machine. The battery the machine came with was bulging and some function issues were noticed. In order to proceed I have to solve the non power up issue.
And, I am not ready to scrap the machine, what else could be the issue?
Is this a good question?
