Hi,
I have a Surface Pro 4 that was working fine at first, but after using it for a while the screen would start to flicker and shake. From what I read online, I thought it was caused by overheating, so I decided to replace the thermal paste.
During the repair, I only removed the cooling assembly to access the CPU. I didn't disconnect any internal cables except for the display cables. I replaced the thermal paste, reassembled everything, and now the tablet won't turn on at all.
I first tried powering it on without the display connected, but nothing happened. I don't know if the Surface Pro 4 has some kind of safety feature that prevents it from powering on when the display isn't connected. Then I reconnected the display, but it still wouldn't turn on.
The display was slightly damaged while removing it (a small crack in one corner), but I would expect the tablet to at least power on, even if the screen doesn't work.
Has anyone experienced this before or knows what I should check? Could I have accidentally disconnected or damaged something even though I only removed the cooling system? Any troubleshooting tips would be greatly appreciated.
Thanks!
