If all primary voltages (VGH, VGL, AVDD) verify perfectly at the test points but the display is blank, distorted, or vertically lined, internal gate shorts are present inside the physical glass LCD substrate rather than on the T-CON board itself. Ksz80 Ob S4lv0.2 Datasheet
If you need help tracing specific paths on this board, tell me the you are evaluating (e.g., a specific resistor or diode) or describe the exact voltage readings you found at your test points. I can guide you through the next diagnostic steps! LVDS SONY LCD PANEL datasheets | Pin | Name | Type | Description
Carrier Sense / Receive Data Valid multiplexed signal to the MAC. RXD[1:0]: 2-bit receive data bus. Management Interface (MIIM) MDC: Management Data Clock (up to 2.5 MHz). I can guide you through the next diagnostic steps
