The TF2106CH TV was displaying a black screen. After opening the cover, I checked the filament light and measured the RGB gun voltages, which were around 200V. There was a visual discharge cutoff. When trying to adjust the high acceleration voltage, a strange phenomenon appeared below the image. I removed the 24C08 chip from the board and tried copying data into a blank 24C08. However, after installation, there was no picture or sound. Further attempts to erase the original memory block failed repeatedly, indicating that the memory was damaged. I then transferred the original data to another memory chip, and everything worked normally again. This repair process involved careful testing and data migration, ensuring that the device could function properly once more. The issue was clearly related to the memory chip's failure, and replacing it with a functioning one restored the system’s performance.
