So I'm having issues with the WQHD (2560x1440) touchscreen LCD on my Thinkpad X1 Carbon 2nd Gen 20A8 series.
The screen is able to display clearly upon boot, but rapidly deteriorates - displaying artifacts, blurring/smudging of colours vertically, fading/greying of some or most of screen, variously.
By applying pressure toward the bottom-right side of the bezel I was able to restore the screen to normal fidelity temporarily - suggesting that the issue lay with either the "LMQ1 Touch Wire" cable, or the screen connector into which it goes.
I then replaced both the LMQ1 and EPD cable (the other cable, on the opposite side, which connects to the screen) for good measure. This failed to resolve the issue.
Consequently, I assume the issue therein lies with the connector itself? See: https://imgur.com/a/bQt9jun
My queries, then, are:
1. Whether more enlightened members would agree with the above assessment; and, if so:
2. Whether this necessitates a full screen replacement; and, if so, (bearing in mind I wish to maintain touchscreen functionality):
3. Whether my replacement options would be limited only to Gen 2 touch screens, or whether I can consider a broader range of 40-pin/EDP screens?
This post viewtopic.php?f=62&t=118906&p=766126 response from fb1996 indicates Gen 2 & Gen 3 screens use EDP, from which I assume I could consider a Gen 3 touch screen replacement?
All and any advice is sincerely and gratefully recieved.
