Accepted Answer

Direct answer to the question • Sony ACDP-085N02 is an 85 W external AC-DC power adapter used mainly with mid-size Sony BRAVIA TVs and a few Sony monitors. • Electrical rating: 100-240 V AC 5060 Hz → 19.5 V DC @ 4.35 A centre-positive barrel, Ø 6.5 mm Ø 4.4 mm with centre pin. • Typical Sony part numbers: 1-492-734-11, 1-849-478-11, ACDP-085N02. • Meets DoE Level VI EU CoC Tier 2 efficiency, includes OVP, OCP, SCP and thermal protection. --- Detailed problem analysis 1. Electrical specification • Input: 100–240 V AC, 1.5–1.7 A, 5060 Hz universal. • Output: 19.5 V DC ±5 %, max 4.35 A ≈ 85 W. • Ripplenoise: < 200 mVp-p 20 MHz BW, full load. • Protections: – OCP trips ≈ 5 A, auto-recover. – OVP ≈ 24 V, latch or auto-restart board-revision dependent. – SCP short-circuit hiccup-mode. – OTP: shuts down ≈ 115 °C case. 2. Mechanicalinterface • Enclosure: black polycarbonate, 127 × 50 × 31 mm, convection-cooled. • DC plug: coaxial “Sony large-pin” 6.5 mm OD 4.4 mm ID, 1.4 mm centre pin; polarity centre +. • Mains cord: IEC 60320 C7 figure-8 detachable. 3. Internal topology for repairers • Input stage: EMI line filter, bridge rectifier, 120400 V bulk capacitor ~100 µF, NTC. • Primary switch: quasi-resonant fly-back or LLC later rev., controller e.g. NCP1250NCP1397. • Secondary: synchronous rectification FET + PI filter. • Feedback: TL431optocoupler; secondary SR controller or discrete gate driver. • PCB single-sided FR-4, 5 mm creepage, Y-cap, 4 kV Hi-Pot. 4. Typical fault symptoms • No standby LED on TV → open primary fuse, blown MOSFET, or primary bulk capacitor ESR. • Flashing power LED cycling → OCPSCP, shorted secondary FET or TV load fault. • Audible chirp → hiccup from bad optocoupler dried 47 µF secondary cap. 5. Compatible equipment most common TV sets: KDL-32W705B, KDL-404248W600B, KDL-40R510C, KDL-48R510C, KDL-40W600B, KDL-43WF66x663, KD-4348W585B, XR-42X90x etc. Monitors: Sony SDM-HX95HX95B, selected professional displays. Always confirm the rating silk-screened at the DC-jack of the device. 6. Electrical equivalence cross-reference • ACDP-085N03 and ACDP-088E01 share identical output and plug – can substitute. • Older APS-243, APS-257 supplies 19.5 V4.7 A are electrically compatible but larger. --- Current information and trends • Regulation: Since 2016 Sony ships ACDP-085N02 in Level VI EU Tier 2 compliant versions typical efficiency 89 % @ full load, < 0.15 W no-load. • Market: Growing influx of counterfeit adapters—visual inspection holographic Sony label, laser-etched ULCE marks, weight ~365 g is advisable. • Future direction: TVs ≤ 100 W are gradually migrating to USB-C PD 20 V profile @ 5 A to reduce PSU diversity; Sony has begun introducing PD-powered 32-inch monitors in 2023. --- Supporting explanations and details • Why 19.5 V? Historical compatibility with Sony VAIO laptop brick inventory; internal TV DC-DC stages tolerate 18–20 V. • Connector anatomy: centre post carries SenseID signal in some models but is internally tied to +V in ACDP-085 series, allowing backward compatibility. --- Ethical and legal aspects • Counterfeits: Sub-standard materials, missing OVP; pose fire risk—UL, TÜV or IEC 62368-1 certification must be present. • E-waste: Replace only when genuinely faulty; high-grade components make the unit repairable. • Liability: Opening sealed adapter voids certification; service technicians must re-test safety Hi-Pot, leakage after repair. --- Practical guidelines Replacement sourcing 1. Prefer genuine Sony or authorised service-part numbers. 2. Match output voltage exactly 19.5 V; current rating ≥ 4.35 A. 3. Verify plug dimensions; adaptors exist in 6.0 × 4.0 mm and 6.5 × 4.4 mm—use calipers. 4. Check for safety marks: UL-E134194, TÜV-R-50119543, PSE, CCC. Diagnostics • Quick test: Multimeter 19.0-20.0 V unloaded; then 4.7 Ω power resistor ~4 A for load test, expect ≤ 0.5 V drop. • Thermal scan: Should stabilise < 65 °C case at 25 °C ambient full load. Repair hints qualified personnel • Replace bulged electrolytics primary 100 µF420 V, secondary 2200 µF25 V. • Check optocoupler CTR, SR MOSFET e.g., AOZ5104. • Always use equal or better ripple-current caps ≥ 500 mA ESR spec. --- Possible disclaimers or additional notes • Some BRAVIA models use a 90 W ACDP-090E03 with identical plug—safe downward substitution higher current but not the reverse. • When TV firmware detects abnormal rail sag < 18 V it may show 5× red LED blink power protection. --- Suggestions for further research • Investigate USB-C PD retrofit boards delivering 20 V5 A to replace barrel connectors in older TVs. • Assess GaN-based replacements for improved efficiency and size. • Study IEC 62368-1 vs older IEC 60950-1 differences for external PSUs. --- Brief summary ACDP-085N02 is Sony’s 19.5 V 4.35 A, 85 W Level VI external adapter feeding many 32-48″ BRAVIA TVs. Keep voltage, current, connector and polarity identical when replacing; beware of counterfeits. Basic troubleshooting involves verifying 19.5 V under load and inspecting for cableconnector damage. Genuine parts ensure compliance with safety and efficiency regulations, while emerging trends USB-C PD, GaN hint at future, more universal replacements.
