Hello every one, i own a white macbook which i bought in march 2008. I have a problem with it,when i turn it on the screen just turns white & nothing else happens. The startup sound/tune can be heard but after that screen turns white it doesnt display the apple logo or anything. i took it over to a computer shop they told me it might be some issue with the screen. i bought a mini hdmi cable & tired hooking it up on my tv, it still doesn't work. Any body faced this problem ? is it worth fixing ? what might be the cost to fix ? Any information will be appreciated !! Thanks !!
