Stepping outside my usual 8-bit and 16-bit microcomputers to diagnose a broken NEC PC Engine.

I start by checking the power and voltage regulators before moving on to reflow the ribbon cable connections. After testing a few capacitors out of circuit, I use an oscilloscope to probe the RAM and data bus, working through the schematics to isolate the fault. The process ultimately points to a bad CPU, which unfortunately halts this specific repair.

Today I have a rubber key 48K ZX Spectrum issue 3B on the bench. This particular motherboard is an unusual dark green color, manufactured in Korea, and it arrived with a completely dead data bus.

Using a diagnostic card and an oscilloscope, I trace the power, clock, and reset signals to figure out why the system refuses to boot. After ruling out the ULA, the focus shifts to the Z80 CPU. I remove the original processor, test a replacement, and install it to see if that resolves the erratic data lines.

Once the repair is done and the display is stabilized with a composite mod, I test the system with a quick run of Manic Miner.

Opening some mail and going through a few items sent in by viewers. The first package contains a ZX Spectrum S-Video mod and some ULA heatsinks. The second is a PC Engine haul, including a Core Grafx console, a CD-ROM2 system, a multitap, and HuCards like Bomberman and Space Invaders. I test the hardware here to figure out what works and what will need to go on the repair bench for a future project.

In this video, I dive into a Sinclair ZX Spectrum Issue 6A repair that's suffering from strange screen colors. Watch along as I perform standard multimeter and circuit diagnostics, hunt down failing 4116 DRAM chips using a thermal camera, track down a bad 100uF capacitor, replace a faulty speaker, and attempt to revive a stubborn keyboard membrane.

Today on More Fun Fixing It, I tackle a Commodore 64 with the classic "black screen" fault. Armed with various diagnostic test cartridges, and the Classic Repair Toolbox software, I chase down a shorted 74LS257 multiplexer and various other faults. What should have been a quick logic chip replacement turns into a much longer journey thanks to a frustrating mistake on the bench. Watch to the end to see the C64 finally pass its diagnostics and to hear about the upcoming Retro Fest 2026 in Swindon.

Today I tackle a dead ZX Spectrum from a huge box of retro repairs. Watch as I diagnose the faults, replace a blown transistor, and perform a composite mod to bring it back to life—along with a slight detour after accidentally frying a few 74LS157 logic chips with reverse polarity! Proof that we all still learn from our mistakes on the bench.

In this video, I take a look at a faulty Acorn Electron sent in by Yawning Angel Keith. Despite the classic "black and white stripes" screen often pointing to RAM or ULA failure, troubleshooting with an oscilloscope reveals a surprising culprit. Follow along as I diagnose the signals, reflow the ULA, and swap parts to bring this childhood machine back to life just in time for Retro Fest.

In this video, I tackle a Commodore 64 with a classic black screen issue. Using a variety of diagnostic cartridges and tools, I narrow down the culprits to a faulty PLA, CIA, and SID chip. Watch as I troubleshoot the board, swap components, and get this vintage machine back toward a functional state.
