      Hello All,

      My OSSC works fine with most of my old consoles on my Sony 4k TV except for my snes which kept loosing the picture. I was advised to buy a de-jitter mod which I have installed this morning, but its sill loosing the picture.

      The OSSC shows
      AV1: RGBS 262p
      15.74kHz 60.08Hz
      and if i press the info button on the controller i get
      Prof.0 320x240p
      262p 44923 (which fluctuates a bit to 44924 but less than before)

      I get the feeling the picture dropout happen less with the de-jitter mod but i cant play with the picture dropping out every 8-60 seconds then coming back.

      Can anyone help before i chuck this expensive OSSC in the bin?

      James

        It’s possible your TV simply doesn’t tolerate a refresh rate that far off of 60Hz. What’s the specific model you have?

        Also, if you ultimately decide you don’t want your OSSC, please instead send it to me; I could use a spare. 🙂

          Check the capacitors in your SCART cable, particularly if it’s an older one.

          Try H-PLL Pre-Coast and/or H-PLL Post-Coast values of around 4.

            Does this line:

            Prof.0 320x240p

            …indicate that it’s using a profile with an optimized mode?

            What happens if you go to Settings -> Reset settings?
