out of sudden, my 3,5" quitted working. Screen kept black. Tried another USB Port and a bunch of other cables Contacted Support via E-Mail and got a troubleshoot.pdf.
As i said before, i tried other cables and other USB Ports. I follow the instructions of the pdf, i shortened the requested squares on the PCB, after that i can upload a Firmware to the device via the goverlay software, the display reboots and it keeps dark and win 10 says it failed to get the devices name. I reinstalled the driver several times and tried every of the 9 USB ports i have on my motherboard (everytime i tried a new USB port i shorten to the programming mode and upload 1 of the 4 firmwares from the forum. When it failed i de-installed the driver and tried it again with the next firmware file, so i´ve done this 36 times with no result). I tried to contact support on 01.November 2021 but got no response at all. My first contact was in October 2021 before the device was 1 year old, so in germany thats kind of a garanty thing the seller has to provide. In my last mail i asked if we are going to replace the display, if i should send it for a repair or if i get a refund cause its not working anymore, nothing but silence. That is not how it should go in my opinion
