📋 A NOTE FROM MY WORKBENCH: Beocom cordless phones (6000 series, 1, 2, 5) operate on DECT or 2.4 GHz technology and rely on NiMH battery packs that degrade after 3–5 years. Charging contacts oxidize, rubber keypads harden, and scroll wheels/jog dials lose tactile feel. DECT handset registration to BeoLine PSTN/ISDN bases can fail due to firmware glitches or hardware aging. Corded analog models (2000/2200/1000) contain custom microcontrollers (Toshiba TMP47C452AN), lithium‑backed memory for phonebook storage, and aluminum‑case electrolytic capacitors that leak over time. I have the expertise, schematics, and replacement parts to restore all Beocom models correctly.
⚠️ CRITICAL WARNING – BEOCOM SPECIFIC: Beocom 6000/1/2/5 handsets contain NiMH battery packs that can leak corrosive electrolyte if left discharged for years. Always remove old batteries before shipping. Charging circuits in BeoLine bases can fail due to dried capacitors, sometimes damaging the handset. Do not leave handsets on base if the base shows no LED activity. I test all charging bases and can repair them as needed.

🔧 Repair‑from‑bench highlights
- BeoCom 6000 – Buttons not working (e.g., «INT», «C»): The lower rubber strip on the PCB loses contact. I disassemble, clean the rubber strip with a soft brush, clean PCB contacts with isopropyl, and reassemble. Contact pins around the keypad must be properly aligned.
- BeoCom 6000 – Handset does not charge: Inspect charging contacts on both handset and base. Verdigris (green oxidation) is common. I clean with DeoxIT, check spring pressure, and re‑solder any cracked joints. If base PSU capacitors are dried, I replace them.
- BeoCom 2 – Broken scroll joystick nipple: I fabricate a repair: remove leftover plastic, slide heat‑shrink tubing over the white plastic stem, and insert a short plastic bolt shaft into the heat‑shrink for rigidity. The repaired pointer provides reliable navigation without replacement.
- BeoCom 2 – Display backlight dim or missing: Many units have cold solder joints on the LED PCB. I reflow the solder for all four backlight LEDs, restoring full brightness.
- BeoLab ・ BeoCom random display lines / boot failure: The ribbon connector for the display becomes oxidized. I clean the ribbon and PCB contacts with contact cleaner, then reseat firmly.
- BeoCom 2000/2200 – No dial tone, intermittent function: Electrolytic capacitors in the PSTN interface and audio sections have drifted out of spec after 20+ years. I perform a full recap using Nichicon PW/Panasonic FC series (105 °C, low‑ESR).
📟 Display ribbon re‑seating caution: BeoCom 6000 and BeoCom 1 use delicate ribbon connectors. Excessive force can tear the ribbon. I use plastic pry tools and never pull by the ribbon cable itself.
📞 BeoLine PSTN / ISDN Base – Common failures
LED not lit, no registration: Internal step‑down transformer or main filter cap dead. I test and replace.
Registration times out: Base not entering registration mode. I check the registration button leaf switch and service the base logic board.
No dial tone from base: PSTN line interface IC (often Si3050 or equivalent) may be damaged. I can replace SMD ICs.
Base resets when ringing: Low current from PSU – dried secondary capacitors. Full recap required.
📡 Base compatibility: BeoCom 6000, BeoCom 1, BeoCom 2 and BeoCom 5 can all be used together on the same BeoLine PSTN/ISDN base (Mk1 supports up to 6 handsets, Mk2 up to 8). I can re‑register handsets to match your base type.

📞 BeoCom legacy (1985–2014): The Beocom line pioneered high‑design telecommunication for the home. From the colourful grid‑phones of the 1980s (BeoCom 1000, 2000, 2200) to the DECT cordless revolution of the late 1990s (BeoCom 6000), and the iconic long‑handset BeoCom 2 and BeoCom 5 of the 2000s, these devices were as prized for their industrial design as for their crystal‑clear sound. Today, NiMH batteries have expired, electrolytic capacitors have dried, and rubber keypads have stiffened. My restoration service replaces batteries, repairs charging circuits, rebuilds broken scroll joysticks, recaps analog boards, and re‑establishes DECT registration. Whether you own a BeoCom 6000, a BeoCom 2, a BeoCom 5, a BeoCom 1, or a classic corded BeoCom 2000/2200/1000, I can restore it to original working condition — preserving these design icons for another generation.
