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

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.

1. Flow chart
Picture does not appear
Check the indication on the indicator in the lower right of the front panel. (STAND BY)
STBY LED flashes
2 times
When error code is detected from panel.
3 times
When temperature increases.
4 times
When 5 V digital system power voltage decreases (2.5 V or less) or becomes excess voltage (6 V or more)
5 times
When 3.3 V digital system power voltage decreases (1.6 V or less) or becomes excess voltage (4 V or more)
6 times
When 6 V analog system power voltage decreases (3 V or less) or becomes excess voltage (7.2 V or more)

When the STBY LED does not flash, the power supply circuit is defective.
2. How to find PDP unit trouble 1) The power voltage for the PDP is supplied correctly. The power voltages are supplied from the switching regulator board CN6, CN23, CN33, CN42 and CN52 to the PDP panel. The four types of power voltage that are 3.3 V, 5 V, 55 V and 80 V are supplied.
2) The input signal is supplied to the PDP panel correctly. The LVDS signal is supplied to CN1 of the circuit board in the bottom of the PDP panel. (CN1 pin-1, pin-3, pin-5, pin-7, pin-9, pin-11, pin-13, pin-15, pin-17 and pin-19) If no images appears through the above conditions are satisfied, the PDP unit will be defective. 3-1
