Dear Sirs,
Thank you for the fast support, the manual does provide all necessary information to repair the radio. All schematics are in a good quality for reading.
The manual fits 100% to my requirements as a technican.
Kind regards Thomas
;
the big video recorder format s-vhs many features delicate in loading system of the cassette. Such machines are no longer manufactured, it would be too expensive.
 ;
THIS MANUAL IS VERY GOOD AND VERY CLEAR
PLEASE NOTE IT DOES NOT CONTAIN THE SETUP INFORMATION TO ALIGHN THE GEARS IN THE CD MECH IT DOES SHOW ALL THE PARTS AND THEIR LOCATIONS .
;
Complete service and operation manual. All schematics are there, all circuit boards AND add-on boards. Including exploded views ,component names and specifications. Also electrical and mechanical adjustment procedures are in this manual. This manual also covers the more advanced BR-S811E unit. Scan quality is fair and usable.
;
High quality scan of original Service Manual. Everything´s fine!
VCC3, VCC5 voltage check PCB-LA � Voltage supply CP151 = 5.0 ± 0.05 V. (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Apply 5.0 ± 0.05 V to CP150. (2) Make sure VCC3 (CP160) is 3.3 ± 0.1 V and VCC5 (CP152) is 5.0 ± 0.15 V.
VCC2 adjustment and VCC7, VCC8, VEE2 voltage check � Voltage supply VCL0(CP101)=5.0±0.05V. (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Apply 5.0 V ± 0.05 V to VCL0 and adjust VR100 so that VCC2 will be 5.0 ± 0.02 V. Notes: � VCC7 = 7.3 ~ 8.3 [V], VCC8 = 12.0 ~ 14.0 [V] � VEE2 = �12.3 ~ �16.7 [V] In addition, disconnect the power and make sure all output voltages are 0 V.
VCO free run frequency adjustment � Voltage supply VCC2=5 V ± 0.05 (V) (CP181). VCC8 = 13.5 ± 0.05 (V) (CP180). VEE2 = �15.0 ± 0.05 (V) (CP182). Connect CP705 (CSY) and CP700 (GNP). (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Monitoring CP710 (HDB) with a frequency counter, adjust VR720 so that the frequency will be 15.734 ± 0.1 [KHz]. Notes: � Disconnect CP705 and CP700, then connect PCB-LA and make sure CP705 (CSY) and CP710 (HDB) are synchronized. � Keep room temperature at 20 ± 10°C. QV-770
