scottmorrall Posted February 3, 2021 Posted February 3, 2021 I've connected the DMD using a separate 12v PSU, it switches on but this is what displays on the screen, The buttons on the back do function as can access the menu (although really hard to read) I have two EVO192x64 boards and both do the same. I'm also struggling to update the firmware by connecting it to a PC via usb. My question: is this software or hardware ? and is it fixable. 20210202_194706.mp4
Content Provider lucky1 Posted February 3, 2021 Content Provider Posted February 3, 2021 Change R32 to 4.7k like modified in the commit from 19June 2020 on github
scottmorrall Posted February 3, 2021 Author Posted February 3, 2021 Cheers, i tried shortening the first ribbon cable and that seems to have worked. Has a little flicker but ill do the other 3 to see if that works
Content Provider lucky1 Posted February 3, 2021 Content Provider Posted February 3, 2021 They changed the input circuit on the latest batch of display panels from china. Changing the R32 will remove the problem.
7hund3r Posted February 8, 2021 Posted February 8, 2021 @lucky1 This change is only for the 192x64 or applied for 128x32/16 either? asking this because for 128x32 and 128x16 the files still with 3.9k Thanks.
Content Provider lucky1 Posted February 8, 2021 Content Provider Posted February 8, 2021 Only for 192x64 otherwise I would have changed the other files too.
