That’s a really interesting issue, and the “black screen for a few milliseconds” symptom with the CSV-7200H usually points to a brief signal re-sync happening in the chain rather than a full failure — which is why it can be so frustrating to troubleshoot. In most cases, this kind of blink is caused by an unstable HDMI handshake, a resolution/refresh-rate mismatch, HDCP renegotiation, or even a cable/port that’s just slightly inconsistent under load. I also liked that you brought it up in such a specific way, because those tiny dropouts are often early warning signs before the problem becomes constant. It honestly reminds me of Trolli Gummy Pops — everything’s fine and sweet, and then randomly you get that one piece that feels “off” for a second 😄. Have you noticed if the black flash happens during specific actions (switching sources, playing protected content, or changing resolution), or does it happen completely randomly?
