I have a iMac 7,1 and the display is a little funky. I bought it from Best buy with a warranty but every time I have them fix it. they don't give me quality parts. On my Macbook when the battery went dead they gave me one made by samsung and it is horrible, you barely get an hour on it. So I want to go directly through with apple. I just don't have an apple care protection plan. Will they fix it just as if I pay them to replace the display? Or do I have to have plan? I just don't want to go through with best buy.
