I recently worked on repairing a 50-inch branded TV with a faulty screen. The motherboard used is the Zhicheng integrated board model 80W70-85V zc-t59s03. After checking Baidu, I couldn't find any official debugging methods for this board. Searching on Taobao also didn’t yield any relevant information—seems like the technical details are confidential.

Frustrated but determined, I decided to experiment. Through trial and error, I confirmed that the remote control signal source +308 can reach the bus. Once connected, the TV displayed the Chinese character option menu, allowing me to adjust the screen parameters. Eventually, I found that setting Ti-Map6bitTi=1 resolved the issue. It was quite a challenge, but it worked in the end.

Here are some images of the process and the final result:
