Apple logo glows orange after lcd panel replacement
MacBook Pro 17" Early 2011 Unibody A1297 2.3ghz i7 Antiglare
I have an early 2011 A1297 early 2011 matte screen macbook pro. The original screen was failing so I purchased a replacement LCD panel online with identical serial number and took it to a technician to get him to replace the panel.
New screen works beautifully after installation but I now have an orange glowing logo on the display case (strange faint lines behind the logo). It is no longer white like it is supposed to be. It's definitely orange, not even a faint pale yellow that I could still live with!
I wrote the repair technician but he doubt it was due to his negligence and suggested that it is a bad panel being supplied. However he is happy to disassemble machine to see if they left anything behind during installation.
I wrote the panel supplier who says there are obviously no led lights on the back of the panel and can't imagine why the glow will be orange if the front of the panel is working fine which makes sense.
Before pinning the blame on anyone and getting it disassembled again, I wonder if anyone knows more about this? Could it be that the video cable or logic board shorted out, backlight fuse blown or WLED driver is damaged? I really can't see why the logo glows orange when the front of the screen works fine.
I already tried to reset the SMC and PRAM, nothing happened.
