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.

Sega Wondermega HWM-5010 Restoration (1st Unit)

Absolute labour of love on this Sega Wondermega HWM-5010 from Japan: corrosion, missing components, broken traces and a RAM package with broken legs. The Mega Drive side eventually came back to life; the Mega-CD side continues to freeze on the BIOS animation, defying everything thrown at it.

Game Gear teardown after the IPS install and before the later accident: the new IPS panel fitted to the mainboard, with the original screen and the parts it replaced set aside, and a Columns cartridge resting beside the console.

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.

N64 Rumble Pak green circuit board after repair, held in a hand. A cluster of blue Kynar jumper wires bridges the broken traces and corroded vias left by the battery leak, the solder on every component has been touched up, and the copper now looks clean and shiny with most of the corrosion gone. The black motor-driver chip sits above.
