Hi there
As it is known issue with MacBook Pro 15" 2011 bad MCP OR what known as AMD GPU
The system wont pass the loading bar, wont post , tested with different drives but nothing .
After replacing the GPU with new chip (which we done hundreds of times for the past years ) system worked just fine for 1 day then it start getting split image, right side to the left and left to right .
Is it GPU again or NVRAM this time ? BTW it has 1TB SSD with few partitions could be possibly bad Macos file system ?
Anyone can comment would be appreciated .
Thanks
