Usually around 15V–17V, powering the source drivers.

Always start by testing the surface-mount fuse near the LVDS connector for 12V.

If colors are washed out or inverted, the Gamma IC or its resistor ladder may be failing.

For professional repairs, this board often requires if the issue lies in the connection between the scaler board and the LCD glass. 32AP11S4LV1.1 Panel Voltage Details | PDF - Scribd

If voltages are correct but the screen is blank, use an oscilloscope to check for data activity on the LVDS pairs.

Typically 20V–30V, used to turn on the TFT pixels.

The LVDS (Low-Voltage Differential Signaling) section receives the raw video data from the TV's mainboard. If signals like are missing or distorted, the T-Con cannot generate an image, even if all power rails are present. 3. Control Signals (CKV and CKVB)

Locate labeled test points on the PCB (e.g., VGH, VGL, AVDD) and compare measured voltages against the Panel Voltage Details.
