中文
含义
错误码E100003表示T-Con板（Timing Controller）故障。T-Con板负责将视频信号转换为面板驱动时序信号，其故障通常表现为显示异常——包括图像撕裂、花屏、白屏或颜色异常等。
常见原因
- T-Con板DC-DC转换器损坏，VGH/VGL/VDD电压异常
- T-Con板主控芯片（TCON IC）固件异常或硬件损坏
- 伽马参考电压生成电路（Gamma Buffer）失效，灰阶误差增大
- T-Con板上的EPROM存储的面板参数数据损坏
- LVDS或V-by-One传输线差分信号对存在短路或断路
自助排查
- 测量T-Con板上各关键电压测试点：VGH（约27V）、VGL（约-7V）、VDD（约12V）、VCOM
- 使用放大镜检查LVDS排线有无针脚弯曲、氧化或断裂
- 断开一侧面板排线，半屏测试判断故障源在T-Con还是面板
- 如电压异常且无明显短路，更换同型号T-Con板测试
English
Meaning
Error code E100003 indicates a T-Con board (Timing Controller) failure. The T-Con board converts video signals into panel driving timing signals. Its failure typically manifests as display abnormalities including image tearing, garbled screen, white screen, or color distortion.
Common Causes
- DC-DC converter on the T-Con board damaged, VGH/VGL/VDD voltages abnormal
- T-Con main controller IC firmware anomaly or hardware damage
- Gamma reference voltage buffer circuit failed, causing grayscale accuracy degradation
- Panel parameter data stored in T-Con board EPROM corrupted
- Short or open circuit in LVDS or V-by-One differential signal pairs
Self-Check Steps
- Measure all key voltage test points on the T-Con board: VGH (
27V), VGL (-7V), VDD (~12V), VCOM - Use a magnifier to inspect LVDS ribbon cable pins for bending, oxidation, or breakage
- Disconnect one side of the panel ribbon and test with half-screen to determine if the fault is in the T-Con or panel
- If voltages are abnormal and no obvious short is found, test with a replacement T-Con board of the same model
