You can check the health of the cable using a Multimeter. To do that, Connect the multimeter probes to the pins and wiggle the wire at the breakpoint. If the multimeter reads the zero or infinite resistance while wiggling the wire. Then you have found the cable is broken.
In case of a broken cable, we recommend using a new one in order to prevent input sources from not recognizing by the TV. If the multimeter won’t read zero or infinite, keep checking until it reads zero.
