I recently worked on repairing a 50-inch branded TV with a faulty screen. The mainboard used is the Zhicheng integrated board model 80W70-85V zc-t59s03. After searching online, I couldn't find any official debugging methods for this board. Even on Taobao, there was no available information, and it seems the technology is highly confidential. Frustrated but determined, I decided to experiment. I discovered that the remote control signal source +308 could successfully enter the bus system. This allowed me to access the Chinese character option menu and adjust the screen parameters accordingly. After some trial and error, I confirmed that setting Ti-Map6bitTi=1 resolved the issue and restored normal display functionality. Below are some images from the repair process:
