    Got my DIY OSSC up and running at the office and it spits out a gorgeous 480p signal to the Insignia NS-32D311NA15 TV on my desk. At home though, where I intend to have it permanently set up, I have a Panasonic TC-P50S60 and it does not recognize any signal from the OSSC at all– no test pattern, no picture from any of the inputs. I’ve tested it with a NESRGB, RGB N64, and SCART PS2, using firmwares 0.69, 0.70, 0.73, and the latest 0.74a, all with the same results at home. Looks like member deltronik has the same TV as me and got theirs working (https://www.videogameperfection.com/forums/reply/8069/) so I’d like to believe there’s some setting I can fiddle with on my unit to at least get the test pattern to show up. Any ideas? My wall-wart PSU is kicking out 5.37V under load so I doubt the PSU could be the cause, but honestly I’m at a loss– it could be anything.

    No test pattern is extremely rare, have you checked your cabling?

    Yep– tried three different HDMI cables all known to work with other 1080p sources. No dice. 🙁

    It sounds like you might have DDC5V signal disconnected from HDMI output, as some displays won’t display anything without that 5V status signal. I suggest checking that fuse F2 is okay and that HDMI pin18 is connected to other end of the fuse.

    Hi marqs, I checked my unit with no display connected– F2 is fine (no measurable resistance across it), pin 18 is carrying a solid 5V, and pin 15 is high.

    Just tested it against my SC512N1-L capture card, and I get the same results as on my Panny– no signal. Don’t know if that’s useful info but figured I’d relay it anyway.
