Uh oh! Your MacBook screen is showing strange lines, discoloration, or even just plain black, despite the machine seemingly working fine? You might be dealing with an internally cracked screen. This isn't your typical shattered glass; it's damage to the delicate LCD panel *beneath* the glass.
So, what causes this? Internal cracks often happen from pressure – maybe something heavy was placed on your closed laptop, or it took a sharp knock. Unfortunately, repairing this isn't usually a DIY job. The LCD is fragile and requires specialized tools and expertise to replace.
Your best bet is to seek professional help. Apple's repair service or a reputable third-party repair shop specializing in MacBooks can assess the damage and offer repair options. Be prepared for a potentially costly repair, as LCD replacements are a significant expense. However, it's often cheaper than buying a brand new MacBook.
