Story: The Ghost in the 17IPS12

When Emre found the dusty service manual tucked behind a stack of appliance boxes at the Istanbul flea market, he almost missed the cover. It read, in cramped technical print: "Vestel 17IPS12 — Schematic & Service Notes." He paid three lira and carried the slim booklet home like contraband treasure.

The 17IPS12 was, by all accounts, an ordinary power-supply board used in countless TVs and monitors. To the technicians who knew it well, its traces and components were familiar—an SMPS controller here, an optocoupler there, the usual cluster of electrolytics that would grow bloated with age. But for Emre, a young electronics hobbyist with more curiosity than patience, the drawing of the circuit looked like a map. He spread it across his workbench, and under the yellow lamp the symbols became streets, the labeled voltages became streetlights.

He began to repair broken monitors for neighbors. Each time he opened a device and replaced a failed capacitor or resoldered a cracked joint, he would glance at the schematic as if it were a set of instructions written by a kindly old mentor. For weeks nothing unusual happened—just warm solder fumes and the satisfying ping of a reviving speaker. Then, one rainy night, a customer brought an older Vestel television that would not power on at all. The set smelled faintly of ozone; its screen was a black, blank promise.

Emre opened the back and found the 17IPS12 board: dust, a hairline crack in the solder mask, and a single, odd hand-written mark on the silkscreen near the feedback loop. Whoever had worked on it before had circled R607 with a ballpoint pen and written a tiny note: "Listen." He frowned; technicians usually left neat labels like "replaced" or "test ok," not invitations.

He replaced the obvious broken parts and powered the set on. The board hummed to life, the multimeter read the expected voltages, and the TV’s backlight flickered awake. Emre sat back to watch static dissolve into color. At first nothing else—then the audio came up with a whisper, like distant voices on a radio. Not a fault, but a soft murmur that rose and fell in time with the AC hum. He leaned in. The murmur resolved itself into a melody he couldn't place: a child’s lullaby hummed in a half-remembered tongue.

Over the next week, Emre tested his own repaired sets and others he found at the market. Each time he touched a 17IPS12 board and powered it, faint sounds would ripple through the speakers—snatches of a language he couldn't name, the cadence of laughter, the briefest echo of an argument. The schematic on his bench seemed to guide his fingers, highlighting paths and points that thrummed like strings. He started to photograph boards and compare notes. Across different serial numbers and manufacturing dates, a scribble like the one he’d seen kept appearing in photos from anonymous sellers: a tiny circle near the feedback resistor, a fleck of blue ink, an almost invisible notch on the edge connector.

People in the neighborhood whispered that the Flea Market Boards had ghosts—leftover voices of the craftsmen who’d tested them, or stray signals caught from broadcast towers long dismantled. Emre’s friends teased him when he told them. "You're imagining it," they said. "Capacitors and ground loops make noise." But a few nights later, his friend Leyla brought a dead monitor that used a different board, not a 17IPS12. Emre fixed it; it worked as expected, quiet as a repaired thing should be. The ghosts, it seemed, were specific.

Emre became careful. He started leaving small offerings at the market: a well-drunk cup of tea beside the soldering iron, a folded scrap of schematic with neat handwriting. With each ritual, the noises shifted. The lullaby sometimes gave way to a voice that recited numbers—dates maybe, or serial codes. Once, while tracing the trace that led to the optocoupler, he heard his mother’s voice humming a nursery rhyme she hadn't sung in years, a memory he had thought buried. He froze, soldering iron hovering over the PCB, heart sharp as a probe.

He traced that path on the schematic and noticed something he hadn’t before: a tiny pair of diodes that formed an unexpected clamp, their orientation reversed in a way that made no sense for normal operation but made everything quieter when he gently tapped them with the tip of a screwdriver. It was as if the circuit had a seam where the world could be heard. He documented it, circled it on his photocopy, and wrote, "Do not alter" in pencil. He began to imagine the schematic not as a drawing of copper and silicon, but as a fragile ledger between the present and a past that insisted on being audible.

Word of the "singing boards" spread. A curious retired technician named Hakan came to visit, and when Emre set a repaired 17IPS12 under the lamp, Hakan listened with the practiced attention of someone who had spent decades tuning televisions with his hands. "These were made in the plant on the outskirts," he said. "We used to calibrate them to account for cross-talk from the radio towers. Maybe some boards kept the ghosts." He laughed, but his laugh had the cadence of someone telling a story he had told himself for years.

The more Emre listened, the more he learned to coax stories from the circuit. When he damped a particular trace with a tiny brush of flux, a memory of a seaside afternoon would wash through the speakers: gulls, salt, the clang of a fisherman's chain. When he bridged two pads with a thin strand of solder, he sometimes heard a voice that spoke his name—no one had ever called him by that nickname. Once, late and tired, he left the lamp on, the schematic face-down. When he woke, the TV was on, and the board hummed a clear refrain: "Find the missing component."

The riddle led him to a small, folded section of the manual he'd initially ignored: a parts table torn at the bottom, with a line missing and the type column cut off. The missing component’s reference matched the position of the blue ink marks. Emre ordered replacements from the old supplier Hakan mentioned. When the package arrived, the tiny components were wrapped in paper printed with an old factory stamp. He fitted one into the empty spot and powered the board.

The television stumbled, then steadied. The voices came now like a chorus, clear and distinct: the voices of technicians long retired, counting test voltages, humming songs from factory lunches, even the voice of someone who said, softly, "Thank you." Emre felt the hair on his arms rise. He didn't know whether he had fixed the board or released it.

News traveled in small ways. Strangers began bringing old Vestel sets with hand-written notes: "Please. If you can, listen." Emre’s bench became a small shrine of repaired things and salvaged schematics. He kept a notebook where he sketched traces and scribbled the phrases that appeared: dates, names, fragments of recipes, the odd declaration of love. He developed a shorthand, a tidy diagram of the 17IPS12 with the points that sang circled in red. He never sold these sets; he returned them to their owners with a soft warning—"They might tell you things"—and a modest repair bill.

One afternoon, a woman arrived holding an old family TV with a sticky note: "For Ayşe. She used to watch at night." When Emre opened it he recognized the handwriting—his grandmother’s. Ayşe had been a neighbor in another neighborhood, someone who had once helped Emre when he was small. He powered the set. The board hummed, then started to play a lullaby—his own mother's voice, then Ayşe's laughter. The woman cried, quietly, and put her hand over the speaker as if to keep the sound from bleeding out into the sky.

Emre never fully explained what the 17IPS12 schematic had become for him: a map of small, private histories preserved in copper and solder. He stopped trying to categorize it as superstition or stray RF. Instead he treated each board like a book found in the library of a city that had lost its past. He learned to listen without expecting answers, to repair without altering the handwriting of the blue ink, to leave one extra cup of tea at the market stall where he bought salvaged parts.

Years later, the factory where the boards had once been made closed and was demolished. New condominiums rose where assembly lines had folded. The schematic lived on in Emre’s photocopies and in the handful of repaired sets that still hummed in attics. Occasionally, when the air was thin and the city quiet at dawn, he could still hear one faint, clear patchwork of voices through a repaired speaker—counting, humming, saying one last instruction in a language that had no name except for the one scribbled on the silkscreen: "Listen."

He did.
