I have a PN60F5300 plasma TV.
It is only about 1 month old now, but I've started to notice a strange issue that occurs only during certain (dark) content.
All content is coming from my PS4 via HDMI so the issue may be on the ps4 side.
I've swapped HDMI cables, and HDMI ports and the issue persists.
During dark scenes, a white noise / artifact will occur. (many pixels that should be dark, will flicker white). Sort of like a random white dust on the screen. Only certain scenes do this this and it is fairly rare.
The issue is isolated to either the PS4 or TV. (i've removed the AVR from the equation).
It happens on both blu-ray content and streamed content (netflix/hulu).
I have a sneaking suspicion it is the TV...perhaps some defect?
I've gone through all of the TV settings and cannot remove it (turning modes auto/off etc).
This is the same issue - looks like it was HDMI cable related?
