中文

含义

T-Con板（时序控制板）故障。画面一半正常一半异常、颜色反转、残影严重或出现噪点画面。

常见原因

  1. T-Con板保险电阻熔断导致VGH/VGL电压缺失
  2. Gamma校正芯片损坏导致灰阶显示严重偏色
  3. T-Con板与面板之间的COF排线接触不良
  4. 主控芯片到T-Con板的LVDS/eDP信号异常
  5. T-Con板DC-DC转换电路输出电压偏离标准值

自助排查

  1. 观察故障画面是否在屏幕中间有明显分界线——多为T-Con问题
  2. 轻轻按压T-Con板连接面板的排线，看画面是否暂时改善
  3. 测量T-Con板上关键测试点电压（VGH约25-30V、VGL约-5~-8V、VCOM）
  4. 检查T-Con板保险电阻是否开路
  5. 更换T-Con板前确认主板提供正确的LVDS/eDP信号

English

Meaning

Timing control (T-Con) board failure. Half of the screen appears normal while the other half is distorted, colors are inverted, severe ghosting, or noisy image artifacts.

Common Causes

  1. Blown fuse resistor on the T-Con board causing missing VGH/VGL drive voltages
  2. Damaged gamma correction IC producing incorrect grayscale levels
  3. Poor contact on the COF (Chip on Film) ribbon between T-Con and the panel
  4. Faulty LVDS/eDP signal from the main board to the T-Con board
  5. T-Con board DC-DC converter output voltages out of specification

Self-Check Steps

  1. Check if the fault has a sharp vertical/horizontal dividing line — a classic T-Con symptom
  2. Gently press the ribbon cables between the T-Con board and the panel to see if the image temporarily improves
  3. Measure key T-Con test points (VGH ~25-30V, VGL ~-5 to -8V, VCOM)
  4. Check the T-Con board fuse resistor for continuity
  5. Before replacing the T-Con board, verify the main board is outputting correct LVDS/eDP signals
