This page details several faults discovered while servicing various PAC-S10/S1 modules and their solutions.
Blank Screen on Power Up - Cartridges and BIOS do not load
Assuming no short circuits were measured across any voltage rail on the PAC, one root cause for this issue is the "D15" signal (IC1, Pin 32) being severed. This trace runs directly under C302, which has likely corroded the trace after years of being exposed to electrolytic fluid.
Restore the signal by reconnecting Pin 32 to the plated via next to the "40" text, adjacent to the BIOS EEPROM.
D15 Signal from IC1 (68000 CPU) damaged from electrolytic fluid corrosion
D15 Signal from IC1 repaired by connecting to an adjacent via
