SD2SNES Pro Black Screen
« on: December 28, 2019, 07:33 PM »
Hi everyone, just looking for some help or to get pointed in the right direction regarding my SD2SNES Pro. I've had the unit for about a month and never had any issues. The other day I removed the SD card to add some ROMs and after I reinstalled it all I get is a black screen. I'm running on an original SNES, and other cartridges still work fine.
I tried multiple SD cards and they all have the same issue. I downloaded the diagnostic firmware and when I turn on the SNES I don't get any LED errors. The screen just remains black for way more than 20 minutes and I never get the "running light" LEDs and the test log is never generated. Any ideas what could be causing this?

Thanks

The diagnostic firmware linked on the website is only for the original SD2SNES.

Here is the link for the SD2SNES Pro:
https://sd2snes.de/files/sd3snes_diagnostic_firmware.zip

EDIT:
it behaves a bit different than the other firmware. It's finished when one LED blinks smoothly and the screen is green.

It appears that there is a bad solder joint or damaged RAM chip on your sd2snes. Could you post the entire log somewhere?

Looks like at least one defective RAM chip or a number of faulty connections between FPGA and RAM chips (not as many as the test suggest since a lot of them will be subsequent faults).
I'd recommend returning it for a replacement (if applicable).
