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 Game Gear Diagnostic: Power LED Only, Nothing Else

Had lunch with a couple of friends and one of them brought a Sega Game Gear along, wondering if anything could be done with it. Power LED only, nothing else.

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.

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.

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 Mega-CD 2: Fuse Fix, Region-Free BIOS & Recap

Dead Sega Mega-CD 2 that turned out to have a single blown fuse. Fuse replaced, region-free BIOS installed, then fully recapped in a follow-up session. Also tidied up some interesting factory bodge cap placements along the way.
