    Thanks! Good idea. I keep forgetting to take"before" photos.

    Take lots of photos if unfamiliar with the process and then you have your own tear down guide.

    This is a great advice. I forgot to take'em and the first time it was a bit hard but doable :)

    Thanks again to everyone for their assistance. Laptop now re-assembled and working with the new cable. Unfortunately the intermittent LCD problem is still there :(. I want to replace the LCD, and will post separately about the apparent problem sourcing a 4k panel.

    I have managed to localise the intermittent behavior to a connection within the LCD panel. I guess the stresses on the panel changed as the laptop lid was moved, deluding me into thinking the LCD cable was responsible. At least I'm now familiar with stripping down the laptop :).

    Peeling back the "Don't touch" black plastic film at the bottom right-hand corner of the screen exposed a PCB where I found a flexible cable from the screen glass to the PCB. Pressing on this restores the picture temporarily. I'm going to try to rig up some semi-permanent means of applying pressure evenly, but for reliability I really want to replace the screen panel.

    Maybe some foam padding to keep pressure on the cable until you source a replacement.

    As for the 4K option it's a bit of a PITA sometimes depending on which model you opt for or additional features desired.

    Thanks. I plan to try the foam.
    Having failed to find ANY 4k panels at reasonable price from UK suppliers with reasonable reputation, it certainly is a PITA.

    The original panel had a very wide colour gamut, valuable to me for photo editing. It would be a pity to sacrifice this. I need the 4k when I'm editing large VJ projects. Wide viewing angle is useful. I can do without G-sync and don't care about response time.

    Any suggestions for sourcing/alternatives? It puzzles me that 4k laptops are available, but not replacement screens.

    I haven't found any UK stock of this (or any 4k) panel at any sensible price from any supplier with good feedback. It generally appears to be out of stock, with no alternative available.
    eg:
    https://www.laptop-lcd-screen.co.uk/shop/CLEVO-P775DM3-G-17.3-UHD-LAPTOP-SCREEN__212521.asp

    https://www.laptopscreen.co.uk/B173ZAN01.0-screen-part-number.htm

    Perhaps from France, when back in stock, but probable problems with importing to the UK now since Brexit.
    https://www.pro-lcds.com/en/au-optronics/1290538-672500-b173zan010.html#/4-finition-matte

    ebay has some at rip-off prices, and not from suppliers with 100% reputation.

    Perhaps helpful to others if continued in my new thread:

    I used kreplacement.com when I did mine as I had attempted to find a particular screen from several different sellers and either they didn't have it or wanted to substitute significantly different models in their place. They're located in China so, they have a reasonable amount of stock of different solutions and cables if needed. Make a list of a couple models you're interested in and shoot them an e-mail to see what they have in stock. All together the cable I needed and panel w/ shipping came out around $150 for 4K on a model that never came with 4K.

    I went with them for a simpler shipping solution since I needed 2 items to complete the swap and didn't want a 2-4 weeks shipping stagger on getting the items in hand. I was kind of indecisive on which direction I was going in from a FHD/60hz panel to whether To keep the same 30 pin cabling and avoid rerouting the cable with a new one for a 40 pin panel and then figured if I'm gong down this road I might as well look into 4K as I had a 4K previously and it was nice to have the real estate to work with. Overall I think I spec'd our at least 50 different options and narrowed them down to 10-15 in a spreadsheet before deciding on a select few. Then hunting them down became an issue all in itself dealing with all the vendors substituting different models instead of the exact model you order. I just happened to stumble upon KR through a google search and landed on a page with their e-mail listed on it and sent them an e-mail. It took a couple of days to hammer out which panel they had in stock from the short list I had narrowed down and then seeing if they had the cable or not.

    I've been running the panel now for a good 6 months now and it's been a great upgrade compared to the original panel that had a layer offset at 45 degrees in polarization causing eye strain.
