Actually I’ve got Microsoft Surface Pro 4 too using for nearly 5 years and experiencing shaky screen after it’s heated or becomes hot. The unit is really excellent with my work being IT System Administrator and other stuff like editing videos and photos. I want to save the laptop. So it’s well known issue now. I searched and tried all the possibilities to solve the issue but failed. The high recommendation is to replace the LCD display. I’m planning to change also the battery. Your experience after changing either LCD display or battery is discouraging cause I’m now hesitant to do it. I might experience the same “totally dead laptop”which is possible after spending. Here in the Philippines most of the repair shop won’t accept to repair and telling better to buy new than repairing. My question is “Is it worth repairing?”
