Overview

  1. Function Description
  2. Important Technical Specifications
  3. Usage Features
  4. Maintenance Features

The HCD-D170/G1100 is a compact disc deck receiver, serving as the tuner, deck, CD, and amplifier section for the LBT-D170 and LBT-G1100 systems. This device is available as a US Model (HCD-D170/G1100) and a Canadian Model (HCD-D170).

Function Description

The HCD-D170/G1100 integrates multiple audio components into a single unit, providing comprehensive audio playback and recording capabilities. It features a CD player, a cassette deck, an FM stereo/AM superheterodyne tuner, and an amplifier.

CD Player Section: The CD player utilizes a compact disc and digital audio system with a semiconductor laser. It supports various playback modes including CONTINUE, SHUFFLE, and PROGRAM. Users can also REPEAT tracks or discs, and an AUTO function is available. Disc selection is facilitated by DISC 1-5 buttons and a DISC SKIP button. The OPEN button allows access to the disc tray.

Cassette Deck Section: The cassette deck supports 4-track 2-channel stereo recording. It includes DOLBY NR for noise reduction and features standard tape operating buttons such as PLAY, FAST FORWARD, REWIND, STOP/EJECT, RECORD, and PAUSE.

Tuner Section: The tuner section is an FM stereo, FM/AM superheterodyne tuner. It allows users to tune into radio stations using TUNING +/- buttons and save them with the TUNER MEMORY button. STEREO/MONO and TUNING MODE buttons provide control over reception. The TUNER/BAND button switches between FM and AM bands.

Amplifier Section: The amplifier section provides audio output to speakers and headphones. It features a VOLUME control, DBFB (Dynamic Bass Feedback) for enhanced bass, and S-SURROUND for spatial audio effects. EFFECT and EQ MEMORY buttons allow for sound customization. A PHONES jack is available for private listening.

General Features: The device includes a SYSTEM POWER switch, a SLEEP button for timed power-off, DAILY 1 and DAILY 2 buttons for daily timer settings, and TIMER SET and CLOCK SET buttons for time-related functions. A DISPLAY/DEMO button controls the display mode, and a REMOTE SENSOR allows for remote control operation.

Maintenance Features

Safety-Related Component Warning: Components identified by a MARK A or a dotted line with MARK A on the schematic diagrams and in the parts list are critical for safe operation. These components must be replaced only with Sony parts whose part numbers appear as shown in the manual or published supplements.

Safety Check-Out: After any service, perform safety checks for AC leakage on antenna terminals, metal trim, "metallized" knobs, screws, and all other exposed metal parts. Leakage current must not exceed 0.5 mA (500 microamperes) and can be measured using a commercial leakage tester, a battery-operated AC milliammeter, or by measuring voltage drop across a resistor with a VOM or battery-operated AC voltmeter.

Notes on Chip Component Replacement:

  • Never reuse a disconnected chip component.
  • Be aware that the minus side of a tantalum capacitor may be damaged by heat.

Flexible Circuit Board Repairing:

  • Keep the soldering iron temperature around 270 °C during repair.
  • Do not touch the soldering iron on the same conductor of the circuit board more than three times.
  • Be careful not to apply force on the conductor when soldering or unsoldering.

Notes on Handling the Optical Pick-Up Block or Base Unit:

  • The laser diode in the optical pick-up block is susceptible to electrostatic breakdown due to potential differences generated by charged electrostatic loads (e.g., clothing, human body). During repair, observe electrostatic breakdown precautions and use procedures included with repair parts.
  • The flexible board is easily damaged and should be handled with care.

Notes on Laser Diode Emission Check: The laser beam is focused on the disc reflective surface by the objective lens. When checking laser diode emission, observe from more than 30 cm away from the objective lens.

All Lights of FL Tube (Servicing Note): To illuminate all FL tube lights, simultaneously press TUNER/BAND, DISPLAY/DEMO, and FILE 2 buttons. To exit this mode, press the same buttons simultaneously again.

Switching the Channel Step 9 KHz/10 KHz (Servicing Note): To switch the AM channel step between 9 KHz and 10 KHz, simultaneously press ENTER/NEXT and POWER buttons. Exercise caution to avoid accidental changes.

Mechanical Adjustments:

  • Clean record/playback heads, erase head, capstan, pinch rollers, rubber belts, and idlers with a denatured alcohol-moistened swab.
  • Demagnetize the record/playback head with a head demagnetizer.
  • Do not use a magnetized screwdriver for adjustments.
  • Apply suitable locking compound to adjusted parts.
  • Perform adjustments with the rated power supply voltage unless otherwise noted.

Electrical Adjustments:

  • Demagnetize the record/playback head with a head demagnetizer (do not bring it close to the erase head).
  • Do not use a magnetized screwdriver for adjustments.
  • Apply suitable locking compound to adjusted parts.
  • Perform adjustments with the rated power supply voltage unless otherwise noted.
  • Perform adjustments in the specified order (playback circuit adjustment before recording circuit adjustment).
  • Perform adjustments for both L-CH and R-ch.
  • Set switches and controls as specified unless otherwise noted.
