This LEGO Retro TV Build Shows You How Cathode Ray Tubes Actually Worked - Yanko Design

"Before flat screens and streaming services, television sets were hulking pieces of furniture that commanded respect and curiosity in equal measure. FMDavid's LEGO Ideas submission celebrates these beloved artifacts with a build that goes far beyond surface level nostalgia, diving deep into the mechanical heart of what made these cathode ray tube televisions actually work. The exterior immediately transports viewers back several decades with its mint green housing, classic rabbit ear antenna, and the unmistakable SMPTE color bars displayed on its gently curved screen."

"Remove the back panel, however, and the true engineering achievement reveals itself. Every major component of a vintage television has been faithfully recreated in brick form, from the deflection coils wrapped around the CRT neck to the colorful wiring snaking between vacuum tubes and capacitors along the chassis floor. Designer: FMDavid And that's what's so fascinating about this build - the inner guts."

"The cathode ray tube dominates the interior volume exactly as it would in an actual 1960s Zenith or RCA, which tells me this builder actually studied reference material instead of just vibing on childhood memories. Those deflection coils wrapping around the tube neck aren't decorative. They're positioned where they'd actually sit in a functioning set, using what appears to be copper-colored flexible elements or possibly custom printed tiles to simulate the electromagnetic coils that would bend electron beams across phosphor screens at 15,734 times per second."

A LEGO build recreates a vintage cathode ray tube television with precise exterior styling and an accurate, exposed interior. The exterior features mint green housing, rabbit-ear antenna, and SMPTE color bars on a gently curved screen. The removable back panel reveals faithfully recreated components: CRT, deflection coils, vacuum tubes, capacitors, and colorful wiring arranged along the chassis. The cathode ray tube occupies the central interior space and the deflection coils are positioned to mirror real electromagnetic beam-bending hardware. The model uses copper-colored flexible elements and custom-like tiles to simulate coil windings. The build functions as both a display model and an educational demonstration of CRT engineering.
