Note:
1. Each bypass capacitor (0.1u/16V) must be respectively closed to pin that is DC power input of scaler IC.
2. LED blue driving circuit is reserved for BenQ model.
3. Bypass capacitor C167,C168,C169,C170,C171,C172,C173 are for ESD and EMI issue. ESD component
EP101,EP102,EP103 are for GPIO direct driving LED. Reserved R193&R194 for Dell 18.5W
4. CN104 is no locked packgae for normal model.CN104 is locked packgae for special model(Dell).
5. RL111,RL112,RL113,RL114 are reserved for some panel spec.
6. CN103 is no locked packgae for normal model.CN103 is locked packgae for special model(Dell).
