DVD/VCR RECEIVER 9-877-959-01 2004F1678-1 © 2004.06 Sony Corporation Home Audio Company Published by Sony Engineering Corporation AVD-K150B/K150E/K150G/K150N/K150R Laser component in this product is capable of emitting radiation exceeding the limit for Class 1. This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Notes on chip component replacement • Never reuse a disconnected chip component. • Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing • Keep the temperature of the soldering iron around 270 °C during repairing. • Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). • Be careful not to apply force on the conductor when soldering or unsoldering. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the following characteristics. • Unleaded solder melts at a temperature about 40 °C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 °C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! • Strong viscosity Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. • Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. 2 NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output several times.

To obtain the best possible surround sound, adjust the speaker parameters (distance, level, etc.). For a normal setup use 6 speakers (2 front speakers, center speaker, 2 rear speakers and subwoofer). Notes • Be sure to match the speaker cord to the appropriate terminal on the components: 3 to 3 and # to #. If the cords are reversed, the sound will be distorted and lack bass. • If you use front speakers with low maximum input rating, adjust the volume carefully to avoid excessive volume output to the speakers. • Do not disassemble the front covers of supplied speakers. Front Speaker (Right) Center Speaker • Front Speakers Based on your listening position, set up the speakers at equal distance. And by hearing position, set up an interval between speakers of 45 degree. • Center Speaker It is ideal that the center speakers and front speakers are same height. But normally place it above or below the television as shown below. • Rear Speakers Place the rear surround speakers to the left and right behind the primary listening area. These speakers recreate sound motion and atmosphere required for surround playback. For best results, do not install the rear speakers too far behind the listening position, install them at or above the level of the listenerês ears. It is also effective to direct the rear speakers towards a wall or ceiling to further disperse the sound. In the case of a smaller room size, if the audience is near to the rear wall set the rear speakers opposite each other, and set the rear speakers 60 - 90 cm above the listener's ears. • Subwoofer This can be placed in any front position.

Required Maintenance The recording density of a VCR(VCP) is much higher than that of an audio tape recorder. VCR(VCP) components must be very precise, at tolerances of 1/1000mm, to ensure compatibility with the other VCRs. If any of these components are worn or dirty, the symptoms will be the same as if the part is defective. To ensure a good picture, periodic inspection and maintenance, including replacement of worn out parts and lubrication, is necessary. Schedules for maintenance and inspection are not fixed because they vary greatly according to the way in which the customer uses the VCR(VCP), and the environment in which the VCR(VCP) is used. But, in general home use, a good picture will be maintained if inspection and maintenance is made every 1,000 hours. The table below shows the relation between time used and inspection period. Table 1 About 1 year About 18 months (1) (2) (3) (4) Grease : Kanto G-311G (Blue) or equivalent Isopropyl Alcohol or equivalent Cleaning Patches Grease : Kanto G-381(Yellow) 5. Maintenance Procedure 5-1) Cleaning 3. Scheduled Maintenance When inspection is necessary 4. Supplies Required for Inspection and Maintence About 3 years Average hours used per day One hour (1) Cleaning video head First use a cleaning tape. If the dirt on the head is too stubborn to remove by tape, use the cleaning patch. Coat the cleaning patch with Isopropyl Alcohol. Touch the cleaning patch to the head tip and gently turn the head(rotating cylinder) right and left. (Do not move the cleaning patch vertically. Make sure that only the buckskin on the cleaning patch comes into contact with the head. Otherwise, the head may be damaged.) Thoroughly dry the head. Then run the test tape. If lsopropyl Alcohol remains on the video head, the tape may be damaged when it comes into contact with the head surface. (2) Clean the tape transport system and drive system, etc, by wiping with a cleaning patch wetted with Isopropyl Alcohol. NOTES: 1 It is the tape transport system which comes into contact with the running tape. The drive system consists of those parts which moves the tape. 2 Make sure that during cleaning you do not touch the tape transport system with excessive force that would cause deformation or damage to the system. Two hours Three hours Drum (Rotating Cylinder) Cleaning Patch Head Tip Coat With Isopropyl Alcohol Touch this section of cleaning patch to the head tip and gently turn the Drum (Rotating Cylinder) Fig. C-9-4 48 AVD-K150B/K150E/K150G/K150N/K150R 5-2) Greasing (1) Greasing guidelines Apply grease, with a cleaning patch. Do not use excessive grease. It may come into contact with the tape transport or drive system. Wipe excessive grease and clean with cleaning patch wetted in Isopropyl Alcohol.
