Great Manual! It contains all the wiring schematics and mechanical exploded views that are essential for service and repair. I was surprised I even found this for such an old machine. Only wish I knew of this site many years ago.
;
Great manual very clear copied. You are making an incredible job. I appreciate a lot the rapidity and your efficiency. Thanks a lot
;
Good pdf of the service manual for this unit. Includes disassembly instructions, full schematics, board layouts, parts lists and diagnostic information. Some information is in the pdf twice (single pages, and split pages), but that could be how it was originally generated by panasonic, or perhaps the idea is to make it eaiser to put onto 8.5 x 11" pages.
Information was exactly what I needed. Delivery was overnight (less than 12 hours) and I was happy with the process.
;
5 STARS for FAST DELIVERY, BEST PRICES and QUALITY PRODUCT. Item was exactly as described with superb resolution. Will definitely source all my future requirements from this website. Thanks a lot owner-manual.com!

OEM manual provided all schematics, board layouts and component specs necessary to facilitate unit maintenance. All pages were clear and readable.

7.1.3 HOW TO DIAGNOSE THE UNIT WITH THE POWER AMPLIFIER SECTION REMOVED
Purpose:
A
When repairing this unit, the large Heat Sink Block obstructs access to some Assys. If the Heat Sink Block is removed, as the posistor mounted on it is also disconnected, the protection circuit is activated, which disables failure diagnosis of these Assys while the unit is powered. With the method explained here, the Assys that cannot be diagnosed while the unit is powered because of the Heat Sink Block can be diagnosed by creating an artificial status of the posistor's being connected (by connecting a 100-ohm resistor under normal temperature). Note: Use this method for diagnosing a failure other than possible failures inside the Heat Sink Block, such as those shown in the table below: Symptoms that are highly suspected to be failures inside the Heat Sink Block
1 No power with the MCACC LED flashing
Possible causes
DC detection has been activated to prevent further damage to the unit. Note: Refer to "7.1.2 How to diagnose the Amplifier Section" in the service manual. The peripheral circuits of the posistor inside the Power Amplifier Section are in failure. Note: A posistor is a kind of thermistor, and its resistance is approx. 100 ohms at normal room temperature.
B
2 The unit turns itself off after "AMP ERR" was displayed on the FL display. Then it goes into state 1 above. 3 "OVERHEAT" is displayed on the FL display under normal temperature, then the unit turns itself off. 4 The unit turns itself off without any indication on the FL
Overloaded amplifier, failure in the overload-detection circuit inside the Power Amplifier Section, etc. 5 "FAN STOP" is displayed on the FL display, then the unit turns Disconnection of the Fan connector, failure in the fan. (Only for the itself off. models for Europe and those for other than North America and Japan)

Procedures:
1 Remove the bonnet and center beam. 2 Remove all the wires from the wire saddle. 3 Disconnect all six connectors connected between the Amplifier Assy and the SP/PS Assy.
� Remove the wires.

2
� Disconnect the parallel wires.
4 Disconnect the parallel wires from the connector CN2201. (If the wires are not easily disconnected, disconnect them with the connector attached, using a vacuum desoldering tool.)

5 Remove the eight screws that secure the Amplifier section.
