MECHANICAL 4.1.1 Shock Sensitivity Refer to Quality plan for the details of the test discs and testing method. Requirement: No muting, plop sounds, picture freeze/jerk or audible/visible interference when impacting with force of - ? In the X and Y directions: F 3g / 3ms, V = 0.06m/s ? In the Z direction: F 2g / 3ms, V = 0.04m/s Where g = acceleration due to gravity. 4.1.2 Thermal Performance Refer to Quality plan for the details of the testing method. Requirements: 1. Set should function normally 2. Temperature rise of accessible parts such as metallic enclosures (casing) shall not exceed 40C above the ambient temperature. 3. Temperature rise of PCB prints shall not exceed 85C 4. Temperature readings of all mechanical / electrical components and modules shall not exceed their specification limits. The calculated junction temperature of semiconductors shall also not exceed spec limits. 4.1.3 Noise Specifications Test Conditions: Measurements are to be made inside an Anechoic Chamber (echo-free environment) with ambient noise of less than 16dBA. Measurements are to be taken at the following positions: - (a) Top-Surface and at center of Front-Cabinet (b) Front-Surface and at center of Front-Cabinet. The microphone is to be positioned 10cm from above mentioned surfaces. Set Functional State Requirement Normal Idle State Standby Mode < 20 dBA Set On and No Disc mode < 20 dBA Tray Open/Close Start/End peak noise < 65 dBA Tray running noise (RMS) < 50 dBA CDDA & SACD Stop to Play peak noise < 35 dBA (Stereo & Multichannel) Play (first & last tracks) <30 dBA Search Forward & Backward (all speeds) <33 dBA Pause (first & last tracks) < 28 dBA Jump Forward (first to last track) < 38 dBA Jump Backwards (last to first track) < 38 dBA Commercial Disc Stop to Play peak noise < 35 dBA Play (inner & outermost title, Layer 0) < 30dBA(TBC) Search Forward & Backward (all speeds) < 35 dBA Pause (inner & outermost title, Layer 0) < 30 dBA Jump Forward (inner to outermost title) < 40 dBA Jump Backwards (outer to innermost title) < 40 dBA Layer Jump (layer 0 to layer 1) < 40 dBA 1-3 LEVEL METER e.g. Sennheiser UPM550 with FF- S/N and distortion meter e.g. Sound Technology ST1700B L R DUT CD Use Audio Signal Disc (replaces test disc 3) SBC429 4822 397 30184 Bandpass 250Hz-15kHz e.g. 7122 707 48001 LF Voltmeter e.g. PM2534 DUT RF Generator e.g. PM5326 S/N and distortion meter e.g. Sound Technology ST1700B Use a bandpass filter to eliminate hum (50Hz, 100Hz) and disturbance from the pilottone (19kHz, 38kHz). Ri=50 Tuner FM MEASUREMENT SETUP 1-4 SERVICE AIDS GBWARNING All ICs and many other semi-conductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wrist wrap with resistance. Keep components and tools also at this potential. ESD CLASS 1 LASER PRODUCT GB Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified, be used Safety components are marked by the symbol !.

The problem was obviously caused by a scratched, dirty or copy-protected CD. In case problems remain, the customer is requested to contact the workshop directly. The lens cleaning (method 3) should be mentioned in the addendum sheet. The final wording in national language as well as the printing is under responsibility of the Regional Service Organizations. 4 LIQUID LENS CLEANING Because the material of the lens is synthetic and coated with a special anti-reflectivity layer, cleaning must be done with a non-aggressive cleaning fluid. It is advised to use “Cleaning Solvent The actuator is a very precise mechanical component and may not be damaged in order to guarantee its full functi
