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.

Looking up 3D comb filters, I found this:

My guess is this is a CRT TV, and these sensors precisely measure the timing of the scan line in the overscan regions (off the sides of the display), and allow the TV to make adjustments.
