OK?..manual is complet and helpfull... for repairing such a old and rare boombox like JVC PCM it is necessary...
;
Super Anleitung. Ordentliche Auflösung. Das ganze noch in Deutsch wäre zu schön. Alle Datenblätter sind sauber Kopiert und alle Leitungswege sind sauber ausgeführt

Thanks God for the internet and thanks for the service like this - proffessional solution on time.

About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.

The downloaded quality was as good as the orignial
SAFETY INSTRUCTION
CAUTION
WARNING : BEFORE SERVICING THIS CHASSIS,READ THE �X-RAY RADIATION PRECAUTION�, � SAFETY PRECAUTION� AND �PRODUCTION SAFETY NOTICE� BELOW. X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially hazard ous X-RAY RADIATION. To avoid such hazards, the high voltage must not exceed the specified limit The nominal value of the highvoltage of this receiver is 23-25KV(14�),25-28KV(20�),25~29KV(21�) at max. beam current, The high voltage must not,under any circumstances, exceed 26KV(14�),30KV(20�),31KV(21�). Each time a receiver requires servicing,the high voltage should be checked. It is recommended the reading of the high voltage be recorded as a part of the service records, It is important to use an accurate and reliable high voltage meter. 2. The only source of X-RAY radiation in this TV receiver is the picture tube. For continuous X-RAY RADIATION protection, the replacemnt tube must be exactly the same type tube as specified in the parts list.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this have special safety-related characteristics. These characteristics are often passed unnoticed by a visual inspection and the X-RAY RADIATION protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage,etc. Replacement parts which have these special safety characteristics are identified in this manual and its supplements, electrical components having such features are identified by designated symbol on the parts list. Before replacing any of these components,read the parts list in this manual carefully. The use of substitute replacement parts which do not have the same safety characteristics as specified in the parts list may create X-RAY Radiation.
SAFETY PRECAUTION
1. Potentials of high voltage are present when this receiver is operating. Operation of the receiver outside the cabinet or with the back board removed involves a shock hazard from the receiver. 1) Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions necesary when working on high voltage equipment. 2) Always discharge the picture tube before handling the tube.The picture tube is highly evacuated and if briken, glass fragments will be violently expelled. 2. If any fuse in this TV receiveris blown, replace it with the FUSE specified in the Replacement Parts list. 3. When replacing a high wattage resistor ( metal oxide film resistor ) in circuit board, keep the resistor 10mm away from circuit board. 4. Keep wires away from high voltage or high temperature components. 5. This receiver must operate under AC260 volts, 50Hz. NEVER connect to DC supply or any other power or frequency.
