Not the encoder. Encoder is there to facilitate recording from HDMI/Analog inputs to USB/cloud/buffering rewind feature/whatever smart TVs do. Maybe you meant Decoder, this one is used when playing streams/files/OTA TV. Also not the culprit - HDMI signal is
not encoded.
The broken path is on the bottom, might be DE/BE blocks(probably not), might XD engine chip. Easiest way to check would be switching TV into "Game mode" - this disables all video processing and should just pass thru HDMI signal to the panel, except this is 120Hz panel so there is still forced frame doubling, and the fact you broke it completely in the mean time

Getting different result after second "just rehot cpu bro" was most likely due to the board cooling under XD Engine in the mean time, and nothing to do with second chip. Why no cold spray before grabbing hotair?

even squeezing chips to the pcb with your finger and looking for difference on the screen would show soldering defects.
btw you earned
https://www.designbyhumans.com/shop/mug/just-rehot-cpu-bro/947188/As other people already mentioned on YT it does look like typical ram problems, most likely XD engine ram used during video enhancement phase, OSD bypasses those and thats why it looked fine. OSD is also frame doubled to native 120Hz meaning turning TV into game mode would probably fix it, now we will never know

Great video, you should do more like this one.
You should have just gave the television to Sagan so he could watch his dad's videos on Youtube or do school work using the browser
how do you know video was great if you didnt watch it? unless you want Sagan to look at pink horizontal lines all day
I'm surprised they went through the complication of having separate paths for the overlay and video. (Might have something to do with the 3D capability.)
https://en.wikipedia.org/wiki/XD_engine it does Video "enhancements", 60-to-120Hz fluidification, motion interpolation, de-blur, de-judder, color correction, dynamic color, dynamic contrast, smoothing, sharpening, removing details because case studies showed people will perceive distorted signal with higher brightest as better etc. You dont want those on your OSD, thats why there are two paths, OSD one bypasses all of this garbage.
