      Hi,

      I bought an OSSC 1.6 from VGP in May last year which has been working fine until yesterday.

      When I normally switch on the OSSC with just the HDMI connected to TV or monitor (no console plugged in) I used to get the grey test pattern come up fine. Now it has started to flicker or the screen jumps around, goes blank or there are green pixels dotted all over the grey test pattern (if it comes up at all)

      Right now I’ve got TX Mode = “DVI” to get the test pattern come up but its green rather than grey and every now and then is jumping around, switching back to a grey test pattern or switching back to green. If I switch the TX Mode back to its default “RGB” then then screen goes blank most of the time or occasionally will flash up a grey test pattern (sometime with green pixels dotted over the screen).

      I’ve tried different firmware (0.83 / 0.88) but not much difference. Tried different HDMI cables too.

      Is my OSSC broken now? Could it be the PSU?

      Any help would really be appreciated. The only really thing I’ve done in the last few weeks is plug a RGB Modded N64 (J) into it via SCART (RGB).

      Thanks
      Alan

        Sounds like a fault with the HDMI transmitter probably. e-mail in and I’ll check warranty status.
