scottmorrall Posted February 3, 2021 Share 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 Link to comment Share on other sites More sharing options...

Content Provider lucky1 Posted February 3, 2021 Content Provider Share 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. Link to comment Share on other sites More sharing options...
