Schematics for the main board needed please. Sticker on board states BN94-07517A but the silkscreen says BN41-02157B. Cant find here or anywhere on the web.

I’m troubleshooting a Westinghouse WD55UW4620 with a strange, very repeatable failure mode and I’m looking for insight on whether this points to the panel itself, T-CON/FRC board, or mainboard.
Any ideas as to what would cause these symptoms?
Symptoms:- From cold power-on, picture is perfect.
- After ~2–3 minutes, the image slowly degrades:
- contrast collapses
- colors wash out / look incorrect (greens especially bad)
- image looks “milky” / flat
- Turning the TV off for a few minutes fully resets it; behavior repeats almost exactly each time.
- Internal
