I have a mobile workstation ZBook15 G3, because the screen has a number of bad spots dark spots and uneven brightness and other issues, so in the HP WeChat public account after the situation opened the maintenance sheet.
The replacement of spare parts has been done three times in a row, but it still failed to solve the problem. The spare parts sent for the first time were even worse than my original ones. There were many bad spots and serious light leakage. The second time it was sent was the factory's fault repair spare parts.
On April 25th, this is already a spare part sent three times. Please see the picture difference. Is this display normal? I am now in China. How can I solve this screen problem quickly and effectively?
This is the original screen!This is the latest screen sent!
