    Ok, so I replaced my daughters LCD Touch Screen on her Lenovo yoga 520 14ikb a while ago and for a while everything was working well, then all of a sudden and for no real consistant reason, the screen defaults to vertical white/grey lines image and a power reset is required.

    After a lot of online investigations, seems to be a common problem with the LCD Screen cable especially around the hinges CAUSING WEAKNESS IN THE WIRING ETC.

    So ordered a new LCD Screen cable from Ebay for £6 (good price) and removed the original LCD Screen cable but unfortunately during the process accidently broke one of the screen sensors (lenovo ls-e543P) connector that plugs into the LCD Screen cable (they are very delicate)

    Anyway – any ideas of where to get a new / used  (lenovo ls-e543P) can be purchased as only a single seller on Ebay in UK selling one for £25 “ouch”  – I have looked on Alibaba etc. and no luck as yet

    Pics below (from internet) of lenovo ls-e543P screen sensor part and screen when image gets distorted

    Note: I have tried the laptop without the sensor but seems to effect Touchpad and keyboard input, so an USB external mouse only solves half the problem and I do not want to disable the Touch screen option unless I have no other choice ;-)

    Ok, so I finally found a single  lenovo ls-e543P sensor board via a seller based in Poland for £11 including delivery , alas not shipping outside of  country whilst the world is in lockdown

    On with search I go ….

    -> https://www.impactcomputers.com/5c50n67555.html

    so i assume …. seller based in Poland selling item for  £11 is reasonable

    I did notice this seller from US, the item price is good value but alas delivery to UK starts from $40 dollars, which is most annoying

    So finally got my Lenovo ls-e543P sensor and have plugged back into LCD Screen cable and re assembled laptop.

    So far all working well, new screen sensor allows touch screen to work with light finger pressure and the replacement LCD Screen cable seems (2 days of testing) seems to have removed the issue with random vertical white and grey lines appearing on the screen

    Thank goodness

    3 weeks later and screen still working well without the random vertical white and grey lines appearing on screen etc.

    So replacing the LCD Screen cable was the solution and another IT job off the list
