What did you get on the AVDD, VGH, or VGL pins?
: The physical dimensions and material of the package, including the type of leads (if any) and any special handling or storage requirements.
Solarized or distorted colors (often caused by the gamma IC or main scaler chip). Vertical lines or "ghosting" across the entire screen. Ksz80 Ob S4lv0.2 Datasheet
In summary, "KSZ80_0B_S4LV0.2" is a T-Con board marking, not a chip-level datasheet. It is associated with the LSY400HM02-A02 board and is used in specific 40-inch Sony and JVC TVs. Understanding its role as a part of a system is key to correctly diagnosing and repairing display failures.
Microchip integrates proprietary LinkMD technology to test cable integrity: What did you get on the AVDD, VGH, or VGL pins
The presence of the "KSZ80" prefix designates a specific variant built for smart display sub-assemblies or panels featuring direct physical layer (PHY) network integration for proprietary device synchronization. Key Semiconductor Profiles
