Manual-link came 30 minutes after having paid for an extremely rare (40 years old) item (sony icr-120) and helped me to get the radio rework again. So really good help for me, fast and reliable delivery and -taken that into consideration- a very reasonable price for that service. So thanks again! Mike, Germany

Some of the pictures in this manual are a bit irritating. I had to dissassemble the unit and some of the screws have different threads, which is not mentioned in this manual. Also some of the drawings of the boards look different than the actual boards.
After all, the manual was very useful. I was able to recalibrate the capstan drive and it is working fine again.

This manual is very good. 303 pages scanned in a very high resolution. My camera has bad, leaking capacitors which all of the V5000 models are suffering from these days.
There is a huge part list with all capacitors, transistors etc. in this manual which helped me a lot. Otherwise I would not have been able to buy replacement parts.
The dissassembly guide is very enormous and detailed. Unlike on the Panasonic MS1 manual I downloaded here it actually looks like the real parts look. And the screws are labeled correctly, so you shouldn't have any left after the repair. ;)

has all the schematics you could need,and very well laid out format also has all part numbers along with an exploded view which is helpful

Very nice to have! Now it is no problem to understand how it is put together.
Helps me a lot.
7. TEST PROCEDURES AND TROUBLESHOOTING
CAUTION - DISCONNECT THE POWER SUPPLY CORD FROM THE WALL OUTLET WHENEVER REMOVING THE CABINET FROM THE UNIT. PROCEED WITH THE TESTS ONLY AFTER DISCHARGING THE HIGH VOLTAGE CAPACITOR AND REMOVING THE LEAD WIRES FROM THE PRIMARY WINDING OF THE HIGH VOLTAGE TRANSFORMER. ( See Figure 3 )

A. TEST PROCEDURE
COMPONENT CHECKOUT PROCEDURE 1) Check for resistance : Across the filament terminals of the the magnetron with an ohmmeter on Rx1 scale. RESULTS Normal reading : Less than 1 ohm.
Figure 5 2) Check for resistance : Across the filament terminals of the magnetron and the chassis ground with an ohm-meter on highest scale. Normal reading : Infinite ohms
MAGNETRON

The chart below shows the firing times of the variable power relay for the EM-G4750 model. The table should be used as a means to check the magnetron is operating correctly and producing any other power setting apart from full power.
