SmartHome Powerlinc 2413S

The SmartHome Powerlinc 2413S (Also branded under parent company Insteon's name as Insteon Powerlinc 2413S) is a serial modem that allows for Home Automation using a computer - for control of lights, outlets, etc. As the main method of communication with smart devices, the Powerlinc 2413S is a pretty important device for users with SmartHome/Insteon networks and a single point of failure for the entire network. Unfortunately for those users, the unit is built with extremely unreliable capacitors that may go bad in as soon as 2 years, and functional replacement devices have crept into high-3-digit figures in price. Fortunately for those users, the capacitors are through-hole, large, and can be repaired for less than $5 plus shipping.

Symptom or Problem Encountered
Green power LED is not on, or glows very faintly. LED may also briefly flash red when unplugged from power. Device is unresponsive.

Causes

 * Aging and cheap capacitors have begun to fail.

Solutions

 * Capacitor Replacement

Disassembly notes
The Powerlinc 2413S is constructed quite simply - 4 Phillips-head screws on the back of the unit hold the top shell in place. A daughterboard inside which holds the RJ45 port is screwed into standoffs, which also hold the main board in place with 2 other screws. Mains power is provided to the board with screw-in terminals that attach to wires on the main board.
