What is the SSD model? Have you accessed Disk Utility and ran a Repair on either drive without errors? Have you tried to access Startup Disk and select the drive to boot into (try the 1TB drive). Have you tried installing a MacOS from a USB drive instead?
Have you tried the following? (1) Try another HDMI cable (2) Verified the input/source on your TV/Monitor is correct (3) Test your PS4 on another TV/Monitor (4) Verify the rear HDMI port on the PS4 isn’t damaged
Thank you for the detailed troubleshooting notes. You will have to try replacing the motherboard and use the rest of the components. Personally, I don’t use absolutely any type of “liquid” on my computers. Hope this helps!
Update: You can go through Samsung’s Service Center’s nearest you and purchase a replacement for ANY model! Hope this helps! https://www.samsung.com/au/support/mobil...-devices/replace-galaxy-buds-cradle/
You can remove the bottom cover and check that your battery isn’t swollen or bulging. I have this exact model and when my battery swelled up, it caused some keys to have louder clicks. Once I replaced the battery with a new one, it was resolved. I’d also suggest blowing out the keys with a can of compressed air in case there’s something stuck under the key.
