I recently finished building a DIY V1.6 OSSC. At first, every line mode except pass through caused a black screen but after reflowing the FPGA everything works except for 5x. I’ve tried reflowing again with no improvement.
I have another OSSC from VGP and 5x works flawlessly on my TV so the issue definitely lies with the OSSC itself.
If anyone could point me in the right direction that would be awesome. Thank you!
