Hi, my macbook pro keeps flickering with vertical lines. Keeps appearing and disappearing every 2 seconds. Would this be due to a loose connection? Is there something I can try to get it fixed? I don’t want to purchase a new screen as it costs more than the laptop itself.
It works fine when I plug it into another display.
No liquid damage and has never been dropped.
Thanks!

Hi. Most likely the LVDS cable has been damaged. Either that or the connector on the board is starting to fail. You can find those displays for pretty cheap, and the repair process is pretty straight forward.

@muricangamer - FYI LVDS is technically a signaling standard. The 2012 Unibody models are the last MacBook Pro's to use LVDS. The retina models use a newer standard called eDP/iDP basically these newer standards are off-shoots of DisplayPort.
Depending on the generation of retina display it will be named either. USB group wasn't the only group messing up naming ;-}
Hi Dan,
I think your thinking of the 2016 and later MacBooks. If this is a 2012-2015 retina than there is only one cable for the display that connects to the top right of the board. The other cables are for connecting to the Airport card. The TCON is on the 2016 and newer MacBooks, that’s the one where the EDP connects the TCON to the underside of the logic board.
Ohh… I did not know that, thx for the info. I work at an AASP and thought it was LVDS since it looked like the same cable. Learning something every day!
@muricangamer - The newer 2016 systems are still using eDP! Thats the short little cable that connects between the logic board and the T-CON board within the uppercase MacBook Pro 15" Retina (Late 2016-2019) Display Cable.
The two display cables from the T-CON board into the display are extensions from the LCD row and column lines.
This is the part most people don't get! Basically, we have a spreadsheet where each cell is a pixel so it takes a given column and row to isolate the given cell once thats done the given sub-pixel is enabled allowing the light to travel through. these two cables are used to drive the LCD.
All displays have a T-CON. For many they are stuck within the display assembly (the better place - cooler). Apple decided to move it to the uppercase (cooking it to death given its placement).
Take a look at this: iMac Intel 27" Retina 5K Display Teardown Jump down to Step 5 & 6 to see a iMac T-CON board. It has a lot more lines! Each of those green ribbons are the column and row lines to light up the discreet pixel cell!
Thanks Anthony. I tried switching LVDS cable but its no luck.
@dan ooooooh Did not know that. That's really interesting. Thanks for pointing that out. I know that the Edp in the 2016 models and newer tend to get damaged due to all the bending from opening and closing the displays. I believe they call it "Flex Gate"?

Do you tend to use a spray cleaner on your display to clean it? If you do then I fear the liquid dripped down wetting the T-CON board messing up the clocking of the scan with corrosion buildup!
You’ll need to take the display off to gain access to the logic within the display assembly, then using some cleaners hopefully clean off the corrosion and if needed resolder the joints. The eDP cable connector may be damaged which would require deeper skills to replace.
Follow this guide Remplacement de l'écran complet du MacBook Pro 15" Retina fin 2013 then review this teardown MacBook Pro Retina Display Teardown so you can see things. carefully lift the T-CON board so you can gain access to the other side. Be very careful here! Unplug the display eDP cable and take some clear pics so we can see what you are facing post them here Ajout d'images à une question existante
