A good manual! fast service and good qualityi for pdf document.
thanks!
 ;
Very helpful and complete manual. Maybe only one negative is schematics have sometimes unreadable name of the parts. But it's not a big problem.
;
Excellent high quality schematics brought my old Heidelberg back to life. Fast download at a reasonable price. Thanks.
;
This document is just what I was looking for, it´s very useful, it contains adjustment procedures for the final stage of the power amp and also
has a complete wiring diagram and description of the main semiconductors used in the design.

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

[+B overcurrent ªOCPº]
Occurs when an overcurrent on the +B(135) line is detected by Q6610 and Q6609. If Q6610 and Q6609 go to ON, the voltage to the pin3 of IC001 go to UP. The unit will automatically turn off. Occurs when an overvoltage on the +B(135) line is detected by D6635, Q6611 and Q6612. If Q6611 and Q6612 go to ON, the voltage to pin6 of IC001 go to UP. The unit will automatically turn off. Occurs when an absence of the vertical deflection pulse is detected by Q6811, Q6819, Q6820, Q6821 and D6801. Shut down the power supply. If the RGB levels do not balance or become low level within 5 seconds. This error will be detected by IC4301. TV will stay on, but there will be no picture. Occurs when an overvoltage of horizontal pulse is detected by D6809 and IC6801. If the voltage of 7 pin of IC6801 goes to High, the voltage to pin20 of IC4301 go to UP. The unit will automatically turn off.
