Samsung TV Boot Loop Due to Main Board Failure

Confirm main board failure as the primary cause if the TV remains in a continuous boot loop despite performing a full power discharge, removing all external devices, and ensuring stable power. The main board is confirmed as the point of failure if the unit cannot initialize its internal logic or firmware, resulting in consistent, repetitive power cycling. This is characterized by the inability of the onboard processor to complete the boot handoff to the display panel or interface, necessitating a hardware-level inspection or component replacement.
