The Y320AN01S4LV0.6 is a critical T-Con (Timing Controller) board primarily used in 32-inch LED and LCD televisions, most notably within the Sony Bravia lineup like the KLV-32BX350. Understanding its circuit diagram is essential for technicians dealing with common display issues such as horizontal lines or double images. Technical Overview & Key Specifications
The T-Con board serves as the bridge between the television's main motherboard and the LCD panel, converting video signals into the specific timing and voltage levels required for individual pixels.
Panel Compatibility: Often paired with Sony 32-inch LCD panels. y320an01s4lv06 circuit diagram pdf new
Input Voltage (VCC): Typically receives 12V from the main board, which is then processed through a DC-DC converter to generate lower voltages like 3.3V or higher AVDD voltages around 15V.
Signal Processing: Handles 8-bit or 10-bit RGB data, usually transmitted via Low-Voltage Differential Signaling (LVDS) to minimize electromagnetic interference. Common Failures and Circuit Diagnosis
Faults in the Y320AN01S4LV0.6 circuit often manifest as distinct visual artifacts. Likely Circuit Area to Check Horizontal Lines
Shorted gate driver tracks (often requires "track cutting" repair) Double Image Mismatch in gate line signals or timing data White Screen / No Picture Failure in the VCC (12V) supply or the gamma correction IC Distorted Colors Gamma corrector circuit or video processing failure Repair & Troubleshooting Tips
When working with the Y320AN01S4LV0.6 Schematic, technicians often follow these diagnostic steps:
Voltage Verification: Measure the 12V VCC at the input fuse. If absent, the issue may be on the main board.
DC-DC Check: Verify the presence of secondary voltages like VGH (approx. 25-30V) and VGL (approx. -5 to -10V). If these are missing, the DC-DC converter IC may be faulty.
Signal Integrity: Inspect the LVDS cable and connectors for corrosion or loose pins. Wiggling these can sometimes reveal intermittent connection issues.
The "Cut Method": For stubborn horizontal lines, experienced technicians sometimes cut specific gate driver tracks (such as the first six lines) to isolate a shorted panel section and restore picture quality.

The Y320AN01S4LV06 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. The part number Y320AN01S4LV06 refers to a specific
Part Number: Y320AN01S4LV0.6 (variants include .3, .4, and .2).
Associated Panel: AUO T320HVN01.2 or similar 32" FHD (1920x1080) modules. Interface Type: 8-bit, 2-channel LVDS interface method.
Operating Voltage: Typically 12.0V (Typ.) input from the main board. Critical Voltage Test Points
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: VCC/VIN: 12V (Main input power).
VGH (Gate High Voltage): Usually between +24V and +32V. This turns the pixels ON.
VGL (Gate Low Voltage): Usually between -6V and -15V. This turns the pixels OFF.
AVDD: Typically 15V to 17V. Power for the source driver's analog circuits.
VCOM: Approximately 5V to 7V. Reference voltage for the liquid crystal common electrode. Common Troubleshooting Steps
Check Fuse: Start by testing the SMD fuse near the LVDS connector for continuity. If blown, check for shorts in the ceramic capacitors (MLCC).
No VGH/VGL: 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.
Bypassing Gate Lines: For panels with "jumping" or "shaking" images, technicians often use "COF bypassing" or "side COF repair" methods found in specialized repair guides.

Why Do You Need the Y320AN01S4LV06 Circuit Diagram?
The PCB containing this component is rarely a simple breakout board. It is usually part of a larger, expensive system. Here is why the schematic is non-negotiable for professionals:
- Reverse Engineering for Repair: Without the diagram, tracing a short circuit or a failed capacitor on a multi-layer board is nearly impossible. The diagram reveals voltage rails, signal paths, and ground planes.
- Firmware & Signal Debugging: If the board uses I2C, SPI, or UART communication, the circuit diagram shows which pins correspond to clock, data, and chip select lines.
- Component Substitution: When an original transistor or resistor fails, the schematic provides its exact value and part number, allowing for a precise replacement rather than guesswork.
- Integration into New Projects: Hobbyists often salvage these modules. The circuit diagram is essential to repurpose the Y320AN01S4LV06 for a new design.
3. Gamma Correction and VCOM Buffers
Many timing controllers include a gamma reference string (GMA1 to GMA14). The new circuit diagram adds resistor values for generating these precise analog voltages. If any gamma voltage is off by more than 50mV, the entire screen will show tinting or inversion artifacts.
1. OEM Support Portals (Best Quality)
If the board originates from a brand like Samsung, LG, or BOE, log into their partner portal. Search for "Y320AN01S4LV06" under the service manuals section. While this requires a registered technician account, the PDFs are vector-based and zoomable to 400% without pixelation.
Alternatives if You Cannot Find the PDF
Despite your best efforts, a brand-new PDF may not exist. Here is what to do next:
- Use a General Datasheet: Search for the main IC on the board (e.g., a "LM2596" or "STM32F103"). The application circuit in that datasheet will closely resemble the Y320AN01S4LV06's implementation.
- Clone the PCB: Remove all components. Scan the bare board on a flatbed scanner at 1200 DPI. Import the image into KiCad or EasyEDA. Manually trace every connection to create your own schematic.
- Contact the Original Equipment Manufacturer (OEM): If the board came from a medical or automotive device, call their technical support. Explain you need the repair schematic for safety compliance. Sometimes they will release it under NDA.
