SC Board (Sustain Drive Board)
The SC board is the primary driver for the plasma panel's sustain pulses; failure of the power transistors (IGBTs) on this board creates a high-load short that triggers the SOS7 protection mode. Replacing the board restores the sustain drive voltage required for panel ignition.

SU/SD Buffer Board Kit
The SU (upper) and SD (lower) scan buffer boards are electrically linked to the SC board. If a buffer board develops a short-circuit, it can immediately blow the replacement SC board, making it standard practice to inspect or replace these when troubleshooting a 7-blink code.

SC Board Component Repair Kit
For granular repair, these kits contain the specific IGBTs (e.g., 30F131, RJP30H2A) and gate resistors that commonly short out. This solves the failure at the component level but requires advanced soldering skills and verification of the driver IC integrity.
