Ksz80 Ob S4lv0.2 Datasheet -

Place one probe on a known chassis ground tab and trace the copper nodes around capacitor on the AVDD line. If the meter registers a resistance lower than

Voltage Gate Low. This negative bias firmly turns off the TFT matrix during rows that are not being addressed, maintaining image stability.

You can find the "KSZ80_OB_S4LV0.2" marking on the physical T-Con board itself, often near the model number of the panel. On this board, you will also find other supporting components:

(for COF punching) rather than standard soldering, making it difficult for DIY repairs. Diagnostic Tip Place one probe on a known chassis ground

To reverse-engineer or troubleshoot this T-CON board, you must look at the key component blocks that make up its architecture: 1. The Main T-CON Processor / ASIC

The string appears to be either:

Configuring the KSZ8081 requires read and write operations over the MDIO interface to specific IEEE 802.3 defined registers and vendor-specific registers. Basic Control Register (Register 0x00) Write 1 to initiate a software reset. Bit 13 (Speed Select): 1 = 100 Mbps, 0 = 10 Mbps.
