X1C 2nd Gen screen hue flicker

#1 Post by lumbasen » Mon Oct 07, 2019 12:52 pm

I have a 2nd Gen X1C (type 20A7) and have screen display issues. It started with a flicker of screen hue that would change out of my standard setting for a second to a red tint (similar to the strongest night light setting). Now it is in the "night light" setting 99% of the time. It flickers back to bright white occasionally (ie on start up, when projecting to another monitor). I've tried changing system settings and rebooting to no avail. Do not recall doing an update prior, however since this appears to be a exacerbating chronic issue I'm not sure it would be related. Is there any way I can fix this? I'm way out of warranty. Thanks!

Welcome to the forum. To me this sounds like a bad wire in the LCD cable which suppresses transmission of one of the base colors.

According to the FRU BOM, the LCD cable has its own FRU (which one depends on your screen type), so it should be possible to order a replacement and test it.

thanks dr_st, I'll look into getting one. To confirm I'm reading the table right, I have a touch screen LCD. Am I looking for 00HM152?

I would suppose so, but there is also the 00HM153 (LED cable touch), and I don't know what the difference is (as all LCDs in this model are LED LCDs). Maybe "LED" in the description of 00HM153 refers to some indicator LED, not the screen type? Don't know...
