      I’m not able to get anything to show up on the HDTV screen besides a test screen (thick vertical lines of different basic colors).
      I’ve tried on 2 separate TV’s and am getting the same test screen on both of them. Also verified that power supply is 5 Volt and 1 Amp.

      Changing the filter does not make a difference either.

      I don’t have any retro consoles that output S-Video or Component to test those.

      Anyone run into this issue, or have any ideas what could be causing it?

      Thanks

        Have you verified that your sources work correctly?

          Sorry for piggybacking, but I’m having the same issue here. Or, I was, and the problem has become worse. Perhaps these details will help?

          Last night, the first time I tested the device, it worked brilliantly. After changing cartridges in the N64, I started only to see a test pattern as described above. I made many more attempts throughout the night, but only successfully saw a picture two more times.

          When I tried again today, the input lights blink rapidly once I introduce the HDMI cable, which I assume is a failure indicator. I have only introduced composite signals from official N64 and Sega Dreamcast cables.

            I now see rapid the input lights blink rapidly once I introduce the HDMI cable

            I had seen the same behavior with the VGA adapter, that took too much current from the miniHDMI and lowered the 5v on the RT2x board to 4v, at least that’s what what I’ve measured.
            Strangely as in your case, everything was fine for a few days.
            First the led blinked for a fraction of a second at power on when the RT2x was new, then for a second, then forever…
            My RT2x died with the same permanent blinking lights.

            I can assume that the device connected to the miniHDMI port takes too much current and somehow affect the RT2x negatively.
            Perhaps removing the 5v from the miniHDMI port will be a good solution for future revisions?

              In the meantime, how obnoxiously difficult would it be to identify the 5V line and cut its trace on existing units?

                This was an assumption, it needs to be tested before fixing anything.
                There is a small fuse/diode (D6) to the left of the miniHDMI port which can be removed to disable 5v.

                  OP, I had the same problem this morning. Turned out to be a problem with my input (N64). I reseated the cartridge and it started working. If you can, try making sure your console is outputting direct to the TV, then try again with the tink. Or do the usual retro console fiddling if you’re getting no video display.
