Pioneer AVR VSX 1123 K stopped passing 3D through.
I have the Pioneer VSX 1123-K and all of a sudden it stopped passing 3D signal through, or rather it doesn't recognize my TV as being 3D.
If I take the Blu-Ray player and connect it directly to the TV the 3D works fine.
If that same Blu-Ray player is unplugged and plugged into the receiver, while the 3D movie is playing connected directly to the TV, the receiver passes the 3D signal just fine.
I had this working initially when I brought the TV home, but I have made some changes since then.
The TV is question an LG OLED E6P.
OLED is a game changer.
