check the circuits arround the ± 15 V line. (Specially check the abnormality of the stabilizing power source circuit.) 3. To clear this stand-by mode, short-circuit the TP801 land on the circuit board. However, clearance of the stand-by mode and turn on the electricity when the repair is not completed may lead to another trouble. - Page 11 Input select switch (DVD) S805: Input select switch (CD) S806: Input select switch (TUNER) S807: Input select switch (PHONO) S808: VGCA switch ( S809: Tape monitor (SOURCE) switch (TAPE MONITOR) S810: Tape monitor (TAPE 2 /MD) switch (TAPE MONITOR) S811: Tape monitor (TAPE 1) switch (TAPE MONITOR) S812: Speaker select switch (SPEAKER B)
- Page 12 VR302: Tone control VR (TREBLE) - Indicated voltage values are the standard values for the unit measured by the DC electronic circuit tester (high-impedance) with the chassis taken as standard. Therefore, there may exist some errors in the voltage values, depending on the internal impedance of the DC circuit tester.
