I currently have two driver board firmwares based on the RTD2660 chip, which are respectively adapted for 4-inch and 5-inch screens, both supporting YPbPr signal input. During actual usage, I encountered an issue with abnormal signal recognition, and the specific situation is as follows:
When connected to a Wii motherboard with a six-layer board design, both driver boards can stably recognize the YPbPr signal, and the display function works normally; however, when replaced with a Wii motherboard with a four-layer board design, neither of the two driver boards can detect the YPbPr signal input, resulting in failure to display properly.
To investigate the root cause of the problem, I tested the signal of the four-layer board Wii motherboard using an LMD-9050 professional monitor. The results showed that it can normally output YPbPr signals in 480P specification, ruling out the possibility that the motherboard itself has no signal output. Subsequently, I also tried to adjust the output parameters of the four-layer board Wii through self-developed software, forcing it to set to standard 480P signal output. However, after connecting to the RTD2660 driver board, the problem remained unresolved, and the phenomenon of signal recognition failure still persists.
