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.

Display RST MASK 13 (green 1023+3). / [MKS S63] Note: Disregard the discharge that may appear during voltage-change setting.
A
Set VOL OFFSET to the setting value 240. / [VOF 240] Gradually decrease the VOL OFFSET value until disappear the discharge (dead cell). � This setting becomes VOL OFFSET_max1.
VOL OFFSET_max1
Note: Make a note of this VOL OFFSET_max1 value.
B
VOL OFFSET_max1 Yes
085?
No
Replacement of abnormal circuits or re-replacement of the panel required
Display RST MASK 14 (blue 1023+3). / [MKS S64]
Set VOL OFFSET to the setting value 240. / [VOF 240] Gradually decrease the VOL OFFSET value until disappear the discharge (dead cell). � This setting becomes VOL OFFSET_max2.
C
VOL OFFSET_max2
Note: Make a note of this VOL OFFSET_max2 value.
VOL OFFSET_max2 Yes
085?
No
Replacement of abnormal circuits or re-replacement of the panel required VOL OFFSET_max
Choose the lower value between VOL_OFFSET_max1 and VOL_OFFSET_max2, and set it as VOL_OFFSET_max.

[From the Recovery flowchart (1-2)]
Is the VOL OFFSET_max value minus the VOL OFFSET_min value greater than 85? Yes
No
Replacement of abnormal circuits or re-replacement of the panel required
E
Are the VOL OFFSET_max value 176 or greater and the VOL OFFSET_min value 091 or less? Yes Set VOL OFFSET to the setting value 139. / [VOF 139]
No
VOL OFFSET_max
176?
No
Yes Set VOL OFFSET to the setting value VOL OFFSET_max minus 37. Set VOL OFFSET to the setting value VOL OFFSET_min plus 48.
Determine the current VOL OFFSET setting value as the final value.
