Vertical Lines Across Upper Diagonal of Screen - Can I Fix?

Hi Eric,

Unfortunately the retina displays are essentially a black box when it comes to replacement parts for them. The only solution based on your described problem is to replace the display assembly. If you do this yourself and purchase the assembly from somewhere like ebay, you could potentially spend as little as 300. Having apple repair this would likely cost between $550-$750. Which is pretty close to the price of a newer computer. I would still recommend taking the laptop into Apple even if you don’t plan on having them repair it, as they will always provide free diagnostics.

If you are comfortable repairing the computer yourself, below is the link to a guide to replace the display.
