What is your TV showing? (e.g., black screen, half picture, lines) What is the exact model number of your television?
Measure voltages sequentially down the Gamma resistor ladder buffer. The voltages should smoothly cascade down from the peak AVDD value down to nearly 0V. If two adjacent pins measure identical voltages or erratic spikes, the Gamma IC is defective and requires hot-air replacement. Finding a Legitimate Y320AN01S4LV06 Schematic PDF Link
Finding exact schematic diagrams for proprietary T-Con boards can be highly challenging because manufacturers rarely release them to the public. However, component-level data sheets and block diagrams are widely shared within the repair community. Where to Download Manuals and Schematics: y320an01s4lv06 circuit diagram pdf link
| Question | Answer | |----------|--------| | | Yes – the manufacturer provides it as a public reference document. Just keep the original source credit if you repost it. | | Can I edit the PDF? | Use a PDF editor to add notes, but do not alter the actual circuit design. For custom changes, create a new schematic in your EDA tool (KiCad, Altium, Eagle). | | What if the PDF is missing? | Contact the manufacturer’s technical support (usually a “Support@y‑tech.com” email) and request the schematic by part number. | | Do I need a special license to use the circuit? | No, the reference schematic is provided for design‑in and troubleshooting. However, if you plan to sell a product that incorporates the IC, you must comply with the manufacturer’s Design‑In and Package‑Use guidelines. | | Is there a 3D model of the IC? | Many manufacturers bundle a STEP file with the schematic. Look for “3D Model (STEP/OBJ)” in the same download section. |

If you are a display repair technician, hardware engineer, or dedicated DIY electronics hobbyist, obtaining a reliable circuit diagram and understanding the underlying voltage rails is crucial for diagnosing a blank screen, distorted graphics, or vertical lines. What is your TV showing
When troubleshooting a T-Con board without a full schematic, checking these standard voltages is the industry-standard starting point: Test Point Expected Voltage Description Main power input from the TV's main board. VCC Digital logic power supply. AVDD 15V – 17V Analog power supply for the panel. VGH (VON) 20V – 30V Gate High voltage used to turn pixels ON. VGL (VOFF) -5V to -10V Gate Low voltage used to turn pixels OFF. VCOM Common reference voltage for the panel. Where to Find Schematic Resources
High-resolution TFT display (often QVGA or higher). The voltages should smoothly cascade down from the

: Many TV brands source panels and T-CON boards from the same few manufacturers (like Samsung). Therefore, the same LTY320AN01 panel and Y320AN01S4 T-CON board could be found in a Sony TV, a Samsung TV, or a generic brand TV. This makes searching by the component number difficult because the official documentation would be under the TV brand and model number , not the component part number.
