Hi again everyone, it would seem a few weeks after my previous post.. something bad has happened to my mac. This time after I finished using the machine I proceeded to close the lid and noticed that the apple logo was still lit up. I reopened the lid and the machine just hung and was unresponsive. I force restarted the macbook and upon booting up again the screen started flickering. Check the link for the video () I live in Singapore and unfortunately there isn't an official apple store here so I had to bring it to an authorised service center. I asked them if this flickering issue was due to the gpu failures and after inspection they said it was an LCD fault which costs upwards of a thousand dollars to repair. Should I try another service center? Perhaps send it to an official Apple store overseas? Or is it time for an upgrade..
