My TV screen has what I’d call black snow on it with dark spots. The dark spots recede away to the edge of the display after the TV has been on for a little bit, but the black snow remains and the picture is washed out. I already replace the Y-Main and upper and lower buffers. Any idea what could be causing this.
This is a display related hard calibration issue. If you have warranty active, call the manufacturer and get it covered for free. They try to fix it first on the spot which they can’t and then will schedule a pickup and a brand new replacement TV. Good luck!
