My MacBook Pro screen flickers and glitches. (Images)

It’s been doing this for a week. It always show resolution issues, pixel tear and horizontal line glitches during startup. Sometimes it stops after a few minutes, and I can squeeze some work time in. Other times it doesn’t stop and I need to leave it shut down.

Can someone give me a possible diagnosis or assistance before I have to go give 600$ for repairing something 1/10 that price. IFIXIT suggests these might be unrepairable ourselves.

It’s horrible. Help!

Edit 1: Never dropped. Minor dings and dents due to usage exist. Movement of display or body does not affect the appearing or disappearing of the glitches whatsoever.

Edit 2: Pairs perfectly with an external display via HDMI, when not glitching. (Image)

Does the screen start glitching like that immediately when you turn it on or only after a certain point on the loading bar?

This looks to me like physical damage to the display, was it dropped or anything? You will most likely just need to replace that. You can do it yourself fairly easily but the part itself is typically well over $500, so it does end up being an expensive repair no matter where you go.

Another thing that occurs to me is it could be the LCD cable that is damaged somehow. You could try replacing that instead (Part: MacBook Pro Retina (2012-2015) Display LVDS Cable): MacBook Pro 13" Retina Display Early 2013 LCD Cable Replacement — It’s a bit of a long-shot but it’s definitely a far cheaper repair so I would try it.

Starts glitching immediately on boot. But once it calms down (most times after a few minutes), it works FLAWLESSLY for hours. Then a sleep or a shut down and it starts going mad again. If I'm unlucky, it won't stop glitching till I shut it down come back to it after a few hours.

Never dropped it, but it does have bumps on the edges due to the backpack hitting edges of walls or doors over the years.

Thank you for replying so quickly!

Is the glitching affected when you put pressure on the display or when you open and close the display? If so it's definitely going to be physical damage.

If you're lucky it could be the LCD cable, I'll update my answer with info on that.

@jonaharagon The glitching seems to have no relation to the movement of or pressure on the display or the device.

@sushmeit I would definitely give the cable a try first if the screen works sometimes, especially since there's no visible cracks on the LCD and moving it doesn't affect anything. You might get lucky. No liquid damage that you know of, or any corrosion around the LCD connector?

It being a GPU problem on the other hand is highly, highly unlikely, but we can rule that out for sure quick. Could you attach an external monitor/TV and see if it's glitching at all? If it doesn't glitch on another monitor then the problem is either going to be the display, the display cable, or the display connector on the logic board.

@jonaharagon No liquid damage that I can remember. Works fine with an external display. I've included an image above.
