Could a failing Internal Interconnect Wiring Harness cause the MARSHALL MAJOR V to have symptom: Major V turning off when in motion/head turns?

The internal interconnect cable passes through the mechanical hinge points and is subjected to constant torsional and tensile stress. Over time, the copper strands inside the insulation fatigue and snap, creating an intermittent electrical connection. When the user rotates the ear cups or moves their head, the physical displacement of the wire causes an open circuit, interrupting power flow and forcing the device to shut down.
