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.
The TV is a Sony KP-43T85T or similar. The service manual is here with on page 55 the exact part: https://www.manualslib.com/manual/772761/Sony-Kp-43t85t.html?page=55#manual
It states “3D COMB FILTER” and is part of the picture in picture mode. It’s probably an optional upgrade, which is why it’s on a separate board if I were to guess.
Awesome!
I found manuals of a similar product, but it did not have the correct labels, may have been a different brand or older models.
I give you props on finding the part!
Is there a reason you took your TV or are you just doing meth?
Is there a reason you’re being disrespectful? If someone lines up parts of their TV like op did for the picture in this post, they are probably not on drugs right now.
