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.

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.
+15 photosPartial fixSega — Game Gear
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.

Every single capacitor on this NEC PC Engine GT handheld had leaked. A careful removal technique preserved all the pads and it came out the other end clean and happy.
