Maintenance Features
The service manual emphasizes several aspects crucial for effective maintenance of the DV118SI(RU) player.
Safety Precautions:
- Power Board: Maintenance personnel must exercise extreme caution when dealing with the power board (220V AC and 330V DC) to prevent injury.
- Antistatic Precautions: Static electricity can severely damage integrated circuits. Measures include using grounded electric conduction metal, antistatic table cushions, grounding all devices and equipment, wearing grounded antistatic wrist rings, and covering/painting operating areas with antistatic materials.
- Laser Head Precautions: Avoid direct eye exposure to the laser head when it is working. Do not use wiping water or alcohol to clean the laser head; use a cotton swab instead.
- Placement Position: Avoid high temperature/humidity, strong magnetic fields (loudspeakers, magnets), and unstable surfaces.
Maintenance Methods:
- Visualized Method: Inspect for physical abnormalities like collisions, missing elements, poor soldering, copper foil damage, wire disconnections, or burnt components. Check power supply and touch components for excessive heat.
- Electric Resistance Method: Use a multimeter to compare resistance values with normal values. For integrated ICs, elements should be broken down for accurate testing.
- Voltage Method: Use a multimeter to test power supply voltage and specific points, judging trouble spots by voltage variations.
- Current Method: Less frequently used due to its cumbersome nature, requiring series connection of the multimeter in the circuit.
- Cutting Method: Used in conjunction with resistance and voltage methods for short circuit and current leakage issues. Isolating circuit levels helps pinpoint the fault.
- Element Substitution Method: Directly replace elements if their condition cannot be determined.
- Comparison Method: Compare voltage and waveform data from a faulty PC board with a known good one to identify issues.
Required Devices for Maintenance:
- Digital oscillograph (≥100MHE)
- TV set
- SMD rework station
- Multimeter
- Soldering iron
- Pointed-mouth pincers
- Cutting nippers
- Forceps
- Electric screwdriver
- Terminals connecting cord
- Headphone
- Microphone
Troubleshooting Flow Chart:
The manual includes a detailed flow chart to guide technicians through diagnosing common issues such as no sound, no image, black and white image, discs not readable, and microphone malfunction. This systematic approach helps identify the cause and suggests actions to eliminate the trouble, often involving checking power supply, connections, settings, or replacing specific components like the insurance tube, rectifying diode, loader pickup, or MT1389 chip.
Waveform Diagrams:
A dedicated section provides waveform diagrams for various signals within the player, including pulse DC of the power board, spindle signal (DMO), feed signal (FMO), traction signal (TRO), focus signal (FOO), FLASH chip signals (SF_DI, SF_CK), 27MHz clock, reset signal (URST), and video/audio output signals. These diagrams are crucial for accurately judging where a trouble lies and improving servicing skills.
PCB Board Layouts and Circuit Diagrams:
The manual includes surface and bottom layer layouts for the Decode Board, AV Board, Power Board, Main Panel, OK Board, and USB Board. Detailed circuit diagrams are provided for the Decode Board, AV Board, Power Board, Main Panel, OK Board, and USB Board, offering a comprehensive view of the player's internal electronics for in-depth troubleshooting and repair.
