Specifically compatible with TVs using the exact PCB number KSZ80_0B_S4LV0.2. Technical Features of the Board Signal Processing: Ksz80 Ob S4lv0.2 Datasheet
When troubleshooting a display problem, checking the DC-DC rail outputs on the board using a digital multimeter is an essential first step. Below are the nominal target voltages under normal operation: Test Point / Rail Nominal Voltage Target Function Main input voltage supplied directly from the TV Mainboard VCC / VDD Logic supply voltage for the T-CON processor and EEPROM VCORE Core logic processing voltage for the central processor AVDD +15.5 V to +17.0 V
The device integrates differential line drivers and receivers with an on-chip analog-to-digital converter (ADC) and digital-to-analog converter (DAC). During transmission, parallel data from the MAC is serialized, scrambled, and encoded into MLT-3 signals for 100Base-TX operation. On the receive side, an adaptive equalizer compensates for high-frequency cable losses, allowing reliable data recovery over distances exceeding 100 meters. Media Independent Interface Support
Uses Time Domain Reflectometry (TDR) to analyze the cable status. Are you designing for a or an automotive environment
Spare parts for this specific board are typically sourced through specialized TV repair suppliers like Great Bharat Spares .
Route TXP/TXM and RXP/RXM as 100-ohm differential pairs. Keep trace lengths matched to within 10 mils to avoid phase distortion and electromagnetic interference (EMI).

The KSZ80 Ob S4lv0.2 is suitable for a wide range of applications, including:
Instead, evidence from various repair forums and technical databases confirms that . A T-Con board is a critical sub-assembly inside a modern LCD/LED TV. Its primary function is to receive the low-voltage differential signaling (LVDS) video signal from the TV's main logic board, process it, and then generate the precise timing signals and column/row drive voltages required to control the LCD panel itself. Without a functioning T-Con board, a TV's screen will remain black or display severe image corruption, even if the backlight is lit.
