Very quality copy of original service manual, which contains the circuit diagrams, PCB and lists of components, well as recommendation for calibration procedures of device, also everything else, that need for repair, tuning and use this oscilloscope.
All presented copies have high-resolution, so you can view all in detail.
This manual will very useful for simple owners and for repairers.
I recommend these manual, because myself is owner of Philips PM3216 and I need sometimes servicing these oscilloscope (principally calibrating).
Also, these document is an example of excellent design of technical documentation.
MAINTENANCE/INSPECTION PROCEDURE
2. Required Maintenance
The recording density of a VCR(VCP) is much higher than that of an audio tape recorder. VCR(VCP) components must be very precise, at tolerances of 1/1000mm, to ensure compatiblity with other VCRs. If any of these components are worn or dirty, the symptoms will be the same as if the part is defective. To ensure a good picture, periodic inspection and maintenance, including replacement of worn out parts and lubrication, is necessary.
4. Supplies Required for Inspection and Maintence
(1) (2) (3) (4) Grease : Kanto G-311G (Blue) or equivalent Isopropyl Alcohol or equivalent Cleaning Patches Grease : Kanto G-381(Yellow)
5) Maintenance Procedure 5-1) Cleaning
(1) Cleaning video head First use a cleaning tape. If the dirt on the head is too stubborn to remove by tape, use the cleaning patch. Coat the cleaning patch with Isopropyl Alcohol. Touch the cleaning patch to the head tip and gently turn the head(rotating cylinder) right and left. (Do not move the cleaning patch vertically. Make sure that only the buckskin on the cleaning patch comes into contact with the head. Otherwise, the head may be damaged.) Thoroughly dry the head. Then run the test tape. If lsopropyl Alcohol remains on the video head, the tape may be damaged when it comes into contact with the head surface. (2) Clean the tape transport system and drive system, etc, by wiping with a cleaning patch wetted with Isporopyl Alcohol.
3. Scheduled Maintenance
Schedules for maintenance and inspection are not fixed because they vary greatly according to the way in which the customer uses the VCR(VCP), and the environment in which the VCR(VCP) is used. But, in general home use, a good picture will be maintained if inspection and maintenance is made every 1,000 hours. The table below shows the relation between time used and inspection period. Table 1
When inspection is necessary About 1 year Average hours used per day One hour About 18 months About 3 years
NOTES:
1 It is the tape transport system which comes into contact with the running tape. The drive system consists of those parts which moves the tape. Make sure that during cleaning you do not touch the tape transport system with the tip of a screw driver and no that force is that would cause deforming or damage applied to the system.
