If one half of the screen is normal and the other half is white, blank, or heavily discolored, the driver data traveling from this scaler board to the panel has been interrupted.

If you are currently troubleshooting a Sony television, I can help you narrow down the exact issue. If you tell me (e.g., vertical lines, no power, black screen with audio), I can guide you through a step-by-step diagnostic process.

Analog Supply Voltage. Powers the internal source driver operational amplifiers responsible for column sub-pixel grayscale levels. +25.0 V to +32.0 V Ksz80 Ob S4lv0.2 Datasheet

Before attempting any hardware modification, ground yourself against ESD and position the television face-down on a protective anti-static foam mat.

When troubleshooting a display using this specific board, monitoring the DC-to-DC converter output is the most critical phase. The absence of even one of these rails results in zero screen illumination or complete image corruption. If one half of the screen is normal

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

This board serves as the bridge between the TV's main motherboard and the LCD panel, processing image signals (LVDS) to ensure correct timing and pixel data for the display.

Place the black probe on the chassis ground (GND) and probe the test points near the RT6503A PMIC. If your meter reads under
