Yeah i guess it’s not worth to fiddle around, the big problem dissapeared and it seems the culprit was found so i’m gonna assume the OSSC is not faulty at all i guess.

I will keep observing it for anomalies anyway, it has a 1 year warranty so i’m not really worried 🙂

The other consoles stopped exhibiting the problem the moment the Mega Drive psu was unplugged from the socket. So i’m guessing that psu was doing something really ugly causing electrical interferences.

And yes, i have a model 1. The faulty psu was a third party one, and the new one i tried with is a third party one too.

So as i mentioned above the only “issue” i can see now is some white dots (pixels) flashing randomly on the screen, but it’s barely noticeable unless you are like really close to the screen.

Ok, i’m gonna update the situation.

I tried the mega drive with a new power supply and the problem dissapeared!
So it seems my OSSC wasn’t faulty after all?
So now that the big thing is out of the question i’d like to ask.

If i get REALLY close to the screen, i can see some white dots randomly flashing on the screen (specially on a black background), almost impossible to see at normal viewing distance, is this expected / normal behaviour? I tried to capture it in a video but it’s impossible.

Thank you!

Yes, i got the OSSC from you, i’m waiting for a friend to come by and lend me another power supply for the mega drive to test.
I will report back and / or write an e-mail.

BuckoA51, have you seen the same issue with another OSSC units? Just so we can know if it’s indeed a faulty one.

Thank you.

I have tried another HDMI cable, another monitor, another plug.

And yes, as i said it happens with all the consoles but the videos are from the mega drive in which it’s a lot more noticeable.

Edit: I just used my Saturn again, to test, and indeed the problem is MINIMAL on that console. It’s still there but you have to be actively looking for it to notice.

Thanks for your answers.

@nmalinoski – I’m inclined to say it’s the cables too, they are cheap and as you said i checked for audio hum and indeed there’s a massive audio hum on white screens (or any screen other than black really)

@SegaFanboy – I do use the default power supply for OSSC as i ordered it with the device. For my consoles i do use the default one too except for the mega drive, but the problem is showing with all the consoles, not just the mega drive (it’s just worse with that one)

I bought all the SCART cables for all the consoles in the same store and they were all equally cheap.

Edit: I decided to open a cable, here are the results!
