I have macbook pro 15 inch retina screen, model mid 2014, without graphic card. Recently, when I connected my laptop with TV via HDMI cable, it went black though when I reset machine, it came back to life again. Though this latest incident, same case but it didn't work. When I bring to apple store to check and they said I need to replace the whole panel. However, I couldn't afford the price so I get it back and plugged it to LCD and the screen came back to life again. Though when I restart machine, it couldn't restart and I have to force quit and started machine again. After many tries, the screen appeared static screen and then black out. Sometimes, it just appeared loading screen and turn black. Though I can login machine and turn on itunes or safari browser using spotlight while the screen was still black. The problems is when I pressed the screen a little, the screen came back to life again. Anyone know the problem? Is it due to the defected screen, loose cable or logic board's problem?
