I feel like they probably have something to do with light level detection or infrared signal receiving but I genuinely have no idea. They could just as likely be part of the sound system for all I know.

Other thoughts: S3001 implies that it’s some kind of switch (also present is D3001 and CN3001 for diode and connector).
One thought is reed switch? Maybe it’s not optical at all. Were there any magnets near this sensor inside the TV? Maybe it’s a way to determine that the screen is fully mounted/aligned correctly?
