    If it's the cable at fault, at least those are fairly inexpensive to replace. Issues at the board can get complicated and pricey.

    Pretty sure it was the cable. The first time I unplugged it from the board, cleaned, and reseated, it was fine...... for about 3 hours. I had another go at it, and wrapped the actual plug with electrical tape. It's now been working great for 2 days and not a single flicker... so fingers crossed the issue was basically loose contacts that were easily triggered because of the way the cable bends at a 90 degree angle right at the plug.

    You have to remove all screws at the bottom, then pop out the keyboard by sticking a screwdriver through the middle screw hole (marked with a keyboard icon). Then unclip the keyboard and move it out of the way (no need to unplug it). Underneath are 5 more screws you need to remove. After this you can take off the back cover. The display cable is plugged in between the GPU heatsink and CPU fan with a shiny plastic black flap/tab ontop of it. The cable itself is fairly thick and black and runs back under the CPU fan. You can't miss it.

    Reseating the cable, as I have discovered, will not actually fix the issue, it is literally cable damage. My previous post describes how I sort of reinforced the cable with electrical tape and this got me an entire 8 days of flicker free usage (a huge improvement from my average of 3 hours to 1 day). Unfortunately and inevitably the issue has come back for me. I also ordered a replacement cable which I received today, and I think this is the only real solution.

    It just looks like the design is somewhat flawed and forces extra stress right at the base of the cable at the mobo side. I guess this is what leads to so many of the cables getting damaged, as this seems like a common occurrence. I'm going to replace the cable (which I ordered from my reseller and actually appears to be a used one ... :( ) tonight and see how that goes.

    Good luck. I will try to reseat the cable first before buying a new one. Thank you!

    Can I ask where you've heard/read others having this issue? It's not a common occurrence as far as I'm aware, but if it is actually a common occurrence... well, I'd like to be aware. :vbsmile:

    I seen at least 4 or 5 people on this forum... I guess I'd consider that common for an issue of this nature.

    Well, my P950 is from a Chinese brand (Terrans Force). If I remember correctly, within months of launch they recalled all the units back to solve the issue that caused the flickering (by changing the cable I suppose)

    Must have been a batch that headed over there, it's not something we have had as an issue.

    I've replaced the cable, wasn't actually as complicated as I thought. About 5 minutes to push the cable through the hinge and get it plugged up. No flickers for now. I guess it's a bad batch of cables and I got unlucky.
