NEC — PC Engine LT

NEC PC Engine LT Recap + LCD Bias Fix (Necromancy)

An epic of strife, perseverance and adaptation. The NEC PC Engine LT is the 1991 laptop-format PC Engine with a built-in colour LCD. Almost always dead from cap leakage. This one needed a full recap, a new voltage regulator, and an off-the-shelf voltage inverter module to replace the T500 LCD bias transformer, killed by the electrolyte. Without that, the screen stays dark.

Sharp — X68000

Sharp X68000: Recap, FDD & Oscillator (No Picture Yet)

A proper exercise in stubbornness on this Sharp X68000. Two rounds of repair, a full recap, FDD surgery (one of the floppy drives had clear signs of a blown capacitor with charring on the PCB), a new oscillator, and still no picture. The X68000 remains on the 'future date' pile.

The underside of the Sharp X68000 Pro II power supply PCB, rested on top of the PSU's metal housing on the floor and being cleaned with a brush and a CompuCleaner air blower; massive electrolyte contamination covers the board, with darkened regions of the PCB and darkened solder joints, grime pooled where the electrolyte ran, and one edge of the board very dark from the contamination.

Sharp X68000 Pro II: Magic Smoke, Transistor & R-Type

Proper saga on this Sharp X68000 Pro II. Magic smoke from a reversed capacitor, an accidental probe short, and enough replaced components to fill a parts drawer before a single faulty transistor finally gave the game away. Got it booting and running R-Type, which was a hard-earned win. Video output later stopped working, so the story isn't entirely over.

Sega Game Gear Japanese: IPS LCD, FM, Flex Cable Fix

This Japanese Sega Game Gear went through a lot: a full IPS LCD mod with speaker upgrade, FM sound module and glass lens, then a trip to the floor courtesy of a curious one-year-old that tore the flex cables. A clock-line bodge wire and a barely-surviving TP10 pad later, everything was restored.

Sega Game Gear Heavy Electrolyte Recovery (2 Units)

Two heavily contaminated Sega Game Gears, so badly that components were falling off the boards from the electrolyte. Many hours in, one has a partially defective screen and the other boots and plays audio with no picture. A partial result after a massive effort.
