HCD-C770/C990 2 Note: Refer to the 5. TEST MODE (page 22) for another self-diagnosis function. Self-diagnosis Function (When letters/numbers appear in the display) When the self-diagnosis function is activated to prevent the system from malfunctioning. In this case a five-character service number (e.g., C 13 00) with a combination of a letter and digits appears on the screen and the front panel display. Refer to the following table. First three c haracters of the service n umber C 13 C 31 E XX (xx is a number) Cause and/or Corrective Action The disc is dirty. , Clean the disc with a soft cloth. The disc is not inserted correctly. , Re-insert the disc correctly. To prevent a malfunction, the system has performed the self- diagnosis function. , Contact your nearest Sony dealer or local authorized Sony service facility and give the 5-character service number.

HCD-C770/C990 3 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. Flexible Circuit Board Repairing -K eep the temperature of the soldering iron around 270 ˚C dur- ing 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. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra- diation exposure. ATTENTION AU COMPOSANT AYANT RAPPORT À LA SÉCURITÉ!

SAFETY CHECK-OUT After correcting the original service problem, perform the follow- ing safety check before releasing the set to the customer: Check the antenna terminals, metal trim, metallized knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE TEST T he AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a r eturn to chassis, must not exceed 0.5 mA (500 microamperes.). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers instructions to use these instruments. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The limit indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a pas- sive VOM that is suitable. Nearly all battery operated digital m ultimeters that have a 2 V AC range are suitable. (See Fig. A) Fig. A.
