    I got the replacement for my interface a few weeks back (USB problem) thanks a lot for that !!

    Now I'm running in a peculiar issue : the screen goes blank (white) after a variable amount of time ...

    It seems to be performing ok as the job started will finish correctly but no way to have information on completion or any other info.

    Is there a reason why that could be ?

    My workshop is not heated permanently and temps can go down to -4°C but never when I run it. Then it is usually around 2 or 3°C.

    Thanks for your help !!

    Take care,
    Marco from France.

    Test it in a warmer room just a step to eliminate that as a cause?

    Hi !!
    did a bunch of tests inside the house (24°C) and the problem persists ...

    Can that come from the display itself (meaning the electronical component) ? should I open the interface and check visually or will the warranty be voided ?

    Thanks a bunch for your help.

    Take care,
    Marco from France.

    With temperatures eliminated, contact the store via Support for further assistance :)

    Is there any way we can get a reference where to get a replacement screen for these interfaces?
    The ribbon cable on mine is cinched off. I've bought 4 different ones, cant seem to get it right. Just want to grab a replacment and hook it up through the port on the other side cause that ribbon cable never stood a chance.

    At this time you will need an Ili9341 2.8" and you have to solder it on as the factory provided one does. The FPC connector cannot be used - the LCD manufacturer discontinued the LCDs with a FPC style ribbon. Soldering it is quite, look up tutorial on YouTube

    Ah that explains it. I can solder, and I have a rework station, but the pads to solder on are just gone, there isn't anything, traces are gone. 'Nother couple hundee down the drain. Thanks
