More than pleased with my prurchase, very good product for the price.

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

ADJUSTMENT
� Video Adjustment (X14-939, X35-428)
* VIDEO adjustments use an accessory remote controller. (The selector of the remote controller is set the Audio mode). 1. Enter the test mode : While pressing and holding the Eject key and SRC key, reset the unit. 2. The main menu screen of the test mode is operated and changed to the chroma IC adjustment mode. In this time, adjustment value appears on the displayed (lower right position). 3. Adjustment value is changed with 8 and 0 key (10 key) for remote controller. 4. Pressing PLAY/PAUSE key is fixed adjustment value of each item. If you can cancel adjustment value, press again PLAY/ PAUSE key. 5. Different item is chosen for 7 and 9 key (key) for remote controller. All item adjustment for step 3 to 5. 6. If all chroma adjustment is finished, pressing DIRECT key that adjustment value is written in EEPROM memory. Exit for adjustment mode when writing for EEPROM.

Adjust the amplitude value so that the waveform between the pedestal to the 9 step signal is 2.45V±0.05V. Adjust the amplitude value so that the waveform between the pedestal to the 2 step signal is 1.1V±0.05V. Adjust the amplitude value so that the waveform between the pedestal to the 10 step signal is 3.4V±0.05V. 1. Connect the oscilloscope to 58pin and 59pin between GND line. 2. It is adjusted so that red signal level bigger 0.1V±0.05V than green signal (for 1step signal).
