Yoga 3 Touch screen - weird "brightness region/crack" issue

Hi guys!


Please help me if you have some experience/thoughts with this weird screen issue.


From day 1 (when I bought the laptop), there was a brighter triangular region in the low left corner of the screen, starting from low left corner of the screen. In this region, all the pixels were 50% brigher, but--it was a relativly small region (5mm x 5mm) in the corner of the screen (just above Win start icon), so I wasn't proactive with servicing it and just left it as it was.


However, the "brightness region/crack" slowly started growing, and, month by month, now it expands from lower left corner to top middle edge. It is a very "geometrical" and triangular region, but some months ago, another independent region started forming more to the bottom center of the screen, which is more circular and doesn't have straight edges.


So this has been slowly progressing for the past 2 years. I' ve finally sent the laptop for service, but the guys there said it is a "result of a liquid spill", which is like totally unacceptable for me, well since obviously a) I haven't ever spill anything over it, b) it was there from day 1, slowly growing in size -- would that happen if it is a result of a spill? It seems to me that liquid spill issues are more "organic shape" spots (more circluar, not triangular), and that they are more-or-less fixed size over time, while this one is triangular and grows with time.

Obviously if this can be the result of some liquid spill, then I'll have to argue with the seller to take over the responsibility, since it was there from day 1.


Any feedback would be really appreciated, especially if anyone has some deeper knowledge on LCD matrices and what might be the cause of this issue... It is a touch screen, btw.

Re: Yoga 3 Touch screen - weird "brightness region/crack" issue

Hello Robz_3

Thanks for using the Lenovo forums.

If the issue was there from day 1, you should`ve went after help sooner, even if not on day one, but when as you say, later it started developing.


It would`ve been best to catch this at the start of things, and not 2 years down the line, as you can clearly see, the damage is now greater, and will likely be more difficult to rectify.


Unfortunately, as much as I want to believe you, I will have to agree with the engineer`s diagnosis, as it looks undoubtedly like liquid damage I`m afraid, or perhaps something overheated, but looks more like what liquid would do to it, especially the later developed fault.


As it stands, I do not think you will get far with the seller I`m afraid, as it has been left for too long, they wont be able to follow this up after 2 years, as it is too big of a gap from date of purchase.


The only thing I could recommend, is that you get in touch with your local Lenovo support for a possible repair, Below is the link to the phone list where you can find these numbers



Hope this helps, let us know how you get on.
