REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. 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. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam- aged by heat. TABLE OF CONTENTS * Replacement of SN761058ZQL (IC501) and LC896442-VH4- 16-E (IC601) used in this set requires a special tool. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. rUNLEADED SOLDER Boards requiring use of unleaded solder are printed with the lead-free 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 viscous (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. ADVARSEL Eksplosjonsfare ved feilaktig skifte av batteri. Benytt samme batteritype eller en tilsvarende type anbefalt av apparatfabrikanten. Brukte batterier kasseres i henhold til fabrikantens instruksjoner. VARNING Explosionsfara vid felaktigt batteribyte. Använd samma batterityp eller en likvärdig typ somrekommenderas av apparattillverkaren. Kassera använt batteri enligt gällande föreskrifter. VAROITUS Paristo voi räjähtää, jos se on virheellisesti asennettu. Vaihda paristo ainoastaan laitevalmistajan suosittelemaan tyyppiin. Hävitä käytetty paristo valmistajan ohjeiden mukaisesti. ADVARSEL! Lithiumbatteri-Eksplosionsfare ved fejlagtig håndtering. Udskiftning må kun ske med batteri af samme fabrikat og type. Levér det brugte batteri tilbage til leverandøren. CAUTION Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturers instruc- tions. ATTENTION AU COMPOSANT AYANT RAPPORT À LA SÉCURITÉ! LES COMPOSANTS IDENTIFÉS PAR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT.

How to release the TEST MODE When method 1 was used: Turn off the power and open the solder bridge on TAP602 on the main board. Note: The solder should be removed clean. The remaining solder may make a short with the chassis and other part. When method 2 was used: Turn off the power. Note: If electrical adjustment (see page 11) has not been finished completely, always start in the test mode. 4-3. TEST MODE STRUCTURE 4-1. GENERAL When entered in the TEST MODE, this set provides the Overall Adjustment mode which allows CD and MO discs to be auto- matically adjusted. In the Overall Adjustment mode, the system discriminates between CD and MO discs, performs adjustments in sequence automatically, and displays the faulty location if any fault is found. In the Manual mode, selected adjustments can be performed automatically. The attached remote control is used to operate the TEST MODE. Unless otherwise specified in the text, the key means that on the remote control. 4-2. SETTING THE TEST MODE 4-2-1. How to set the TEST MODE To set the TEST MODE, two methods are available. 1 Solder bridge and short TAP602 (TEST) on the main board. Then turn on the power. MAIN BOARD (SIDE A) 2 In the normal mode, operate the keys on the set and those on the remote control as specified below: Turn on HOLD switch on the set. Holding down x(STOP) key on the set, press the keys on the remote control in the following sequence:>t >t .t .t >t .t >t .t t 4-2-2. Operations when the TEST MODE is set When the TEST MODE is entered, the system switches to the dis- play check mode within the TEST MODE. From this mode, the other Test modes can be accessed.
