Installation Notes

Installation should be performed by a qualified electronics service technician with experience in board-level television repair. Always disconnect the television from AC power and allow capacitors to discharge before handling internal components. Use ESD-safe tools and a grounded wrist strap when handling the PCB to prevent electrostatic damage. Confirm the root cause of failure before replacing the board to avoid installing a new assembly into a system with an unresolved fault condition.
