Source for diffuser behind LCD panel
I recently replaced the LCD screen of a friends Macbook Air A1370, but in doing so I scorched the white plastic diffuser immediately behind the LCD panel. I used an SMD heat gun so the hot air was concentrated in the right area but I must have hovered over that area too long. There are 3 sheets between the LCD and back light but only the topmost has been affected. The wrinkle is about 2 inches across the top so it prevents the LCD panel from laying flat after reassembly.
Does anyone have a source for either this top diffuser or the set.
Is this a good question?
