When repairing a Y320AN01S4LV06 board, you must verify several key DC-to-DC converter voltages . Failure of these voltages often indicates a faulty PMIC (Power Management IC) or shorted capacitors: 12V (Main input power).
Approximately 5V to 7V . Reference voltage for the liquid crystal common electrode. Common Troubleshooting Steps
Typically 12.0V (Typ.) input from the main board. Critical Voltage Test Points y320an01s4lv06 circuit diagram pdf new
Start by testing the SMD fuse near the LVDS connector for continuity. If blown, check for shorts in the ceramic capacitors (MLCC).
Y320AN01S4LV0.6 (variants include .3, .4, and .2). When repairing a Y320AN01S4LV06 board, you must verify
For panels with "jumping" or "shaking" images, technicians often use "COF bypassing" or "side COF repair" methods found in specialized repair guides .
If the input 12V is present but VGH/VGL are missing, the DC-DC IC may be damaged or a ceramic capacitor on the gate line may be shorted. Reference voltage for the liquid crystal common electrode
Usually between +24V and +32V . This turns the pixels ON.
The circuit diagram and datasheet refer to a specific 31.5-inch LED/LCD Scaler PCB Board often integrated into AUO (AU Optronics) panels, specifically the T320HVN01.2 series . While the full proprietary schematic is rarely released as a single "new" PDF, technical specifications for this board and its associated panel are essential for troubleshooting display issues such as "no picture" or "white screen". Technical Specifications & Identification
The Y320AN01S4LV06 is a panel scaler board (also known as a T-CON or source driver board) that converts LVDS signals from the TV's main motherboard into data signals for the LCD pixels.
