Hi Guys, I don't know if some of you already experience this but yesterday morning, I tried booting up my macbook aluminum and succesfully i got in to the homepage. Now what I did (and usually do), is open safari and access facebook. For some reason, when I got in my screen began to flicker (as in no exageration flicker na parang bad signal sa tv) and its causing my macbook to hang a bit. What I did was force it to shut down by pressing the power button kasi non responsinve na sya. And when i turned it back on, it did.. i heard the chime, and looks like the volume is working and there's even a backlight pero wala na talagang lumalabas sa screen (until now). I tried taking it to an apple service center here in singapore and we did the reset pram/vram thing and there was no result. So the only way for them to check it is to have it diagnosed and I don't have that enough time to leave it there since I'm leaving for KL tomorrow. And here's the sad part, I don't have an apple care plan for it so no warranty already. Is there another troubleshooting (aside from reseting pram/vram) process that I can do on my own to check if it will work again. I hope its not the logic board (Please God one year and 2 months palang to). Also, just in case I need to have it serviced , san mas maganda magpacheck na center sa manila? and hopefully sana free lang check up and pay nalang kung ipapaserviced talaga. Any suggestions? Thank you so much guys in advance!!!
