Hi iFixit, I recently replaced my hard drive with an SSD using this bundle: iMac Intel 21.5" Retina 4K Display Hard Drive Replacement The speed works great and the repair was easy. But I noticed that there’s a purple/purple hue on the left and right side of the screen. Do you know what the reason for this might be ? I want to order more adhesive and fix it up, but I’d like to know if you have any ideas before I start. Thanks, Rama
OMG, you have the dreaded Hendrix, “Purple Haze” problem, RUN it may be contagious. https://www.youtube.com/watch?v=cJunCsrh…
Purple hue generally points towards a signal problem. Check the video connector for loose/damaged connection between the LCD and main logic board. Be sure to check both ends. Hopefully a simple reconnect will fix this.
@rama_watts Sadly, you’ve isolated the issue down to the display. Some how you managed to damage it in the process of taking it off. You’ll need to replace it if you can’t live with the haze effect. Here’s the needed part iMac 21.5" LCD Display Panel - Retina 4K (used) P/N 661-02990
@rama_watts “there’s a purple/purple hue on the left and right side of the screen.”Blue/Purple hue issues are actually most commonly caused by LED backlight issues. Sure, a new display panel will fix the issue since the backlight is part off it, but you wanted to “know what the reason for this might be ?
