Technicians frequently encounter specific component failures in the PS-4241-9HA

model. If your unit is not outputting power or has no standby voltage, the following components are likely culprits:

TNY279PN IC: The most common point of failure for "missing standby voltage." It is the primary controller for the standby rail.

1-Ohm Feed Resistor: This resistor often burns out when the standby IC shorts, acting as a secondary fuse for that sub-circuit.

Electrolytic Capacitors: Over time, the main primary capacitor or smaller secondary filter capacitors can bulge or leak, leading to fluctuating output or start-up failures.

Zener Diodes: Diodes near the standby IC should be checked for shorts if the standby rail is dead. Purchasing & Replacements
