MacBook Pro Mid 2012 display glitching out

It just glitch out all of sudden while using it.

Block Image

I disabled the drivers the glitching are gone but I can’t do of my work because of lack of drivers. Do anyone know how to fix this issue?

I changed the background and re enable the drivers still have the issues.

Can you set the desktop background to default, reenable the drivers, take another picture of the desktop, and post it here? Ajout d'images à une question existante

I added a photo with the default desktop background

@bryantier - If your desktop image is the same on both displays the CPU graphics services have failed, you’ll need a new logic board to fix this.

Plug in an external display if the externals image is clean then the internal display and/or its connections to the logic board has a problem! This could be corrosion damage on the LVDS cables connection at the LCD panel or logic board or the LCD panel. Follow this guide Remplacement de l'écran sur Macbook Pro 13" Unibody mi-2012 to inspect the logic boards connection (Step 14) inspect both the cable and board contacts for corrosion damage.

It’s a bit more work to check the display side as you’ll need to pop off the bezel to see the LVDS connection. I often see the display side damaged from people who spray their display with cleaner which drips down wetting the contacts most of the time its to far gone to repair requiring replacement.

@bryantier - Ouch! Not good ;-{

Your logic board has died! This model uses the intergraded Intel graphics engine HD Graphics 4000 which is part of the CPU chip. Time for a new logic board Remplacement de la carte mère du MacBook Pro 13" Unibody mi-2012

Do not rush to change the board. Try changing your memory first. Memory used in the work of graphics and is often the cause of a breakdown. I do not think that the problem is in the CPU-GPU because then the laptop would not be able to turn on.

try booting a macbook from a windows flash drive. Windows has her own drivers. Write if anything changes.

@yur_lap - Why do you think MS Windows would change a physical defect (bad logic board) and why would you even switch out the OS from macOS?

Downloading from Windows will help you understand what the problem is - in drivers or hardware. Bad motherboard is too general a term. What exactly do you mean? Processor, bridge etc?

@yur_lap - The issue is physical not software (drivers) installing Windows won't change the this. uuid you have deeper micro-electronics skills and access to the schematics and board view drawings you might be able to fix this. This is well beyond a DIY fix, as such replacing the logic board is the only option.

The test was seeing if the problem was present on the external display, it points us to the failure as being within the logic board. Review this guide to see what's involved Remplacement de la carte mère du MacBook Pro 13" Unibody mi-2012

@danjMacBook Pro 2012 Mid has removable RAM. Some of this memory is used by integrated video. Therefore, problems with screen output may be caused by faulty memory. It's easier and cheaper to check it than replacing the motherboard. Why do you offer the most expensive repair option, it does not provide a 100% guarantee, but causes high costs. There is no cost to checking your memory...
