COF (Chip-on-Film) and gate driver failures traditionally meant a dead TV, but bypassing techniques give these displays a second life. Understanding Screen Bypassing Techniques
When a television is stuck on the logo screen, restarts continuously, or fails to boot, the issue usually resides within the main logic board. The manual covers:
: It features clear, close-up images of panel test points, copper traces, and COF structures, allowing technicians to locate target modification zones easily. The large electrolytic capacitor on the primary side
The large electrolytic capacitor on the primary side of the Power Supply Unit stores roughly 380V to 400V DC when active. This capacitor can hold its charge long after the TV is unplugged.
