Check the needed lubrication and the conditions of cleanliness in the unit. Check with the customer to find out how often the unit is used, and then determine that the unit is ready for inspection and maintenance. Check the following parts. Phenomenon Color beats Replacement Inspection Dirt on full-erase head o Poor S/N, no color Dirt on video head o Vertical or Horizontal jitter Dirt on video head Dirt on tape transport system o Low volume, Sound distorted Dirt on Audio/control head o Tape does not run.

Supplies Required for Inspection and Maintence 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. (1) Grease : Kanto G-311G (Blue) or equivalent (2) Isopropyl Alcohol or equivalent (3) Cleaning Patches (4) Grease : Kanto G-381(Yellow) : Used only for Reel S and Reel T 5) Maintenance Procedure 5-1) Cleaning 3. Scheduled Maintenance (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. 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 About 18 months About 3 years Average hours used per day NOTES: One hour 1 Two hours 2 Three hours 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. Drum (Rotating Cylinder) Cleaning Patch Head Tip Coat With Isopropyl Alcohol Touch this section of cleaning patch to the head tip and gently turn the Drum (Rotating Cylinder) Fig. C-9-4 76 MAINTENANCE/INSPECTION PROCEDURE (2) Periodic greasing Grease specified locations every 5,000 hours. 5-2) Greasing (1) Greasing guidelines Apply grease, with a cleaning patch. Do not use excess grease. It may come into contact with the tape transport or drive system. Wipe any excess and clean with clean ing patch wetted in Isopropyl Alcohol. 1) Loading Path Inside & Top side 2) Shaft 3) Gear Rack F/L Moving Section 4) Shaft 5) Lever Tension Groove 6) Clutch Assembly D33 Shaft 7) Brake "S" Rubbing Section NOTE:Greasing Points 1) Loading Path Inside & Top side 2) Base Tension Boss inside Hole 3) Arm Assembly F/L "U" Groove 4) Arm Take-up Rubbing Section 5) L/D Motor Worm Wheel Part 1 6) Shaft 7) Arm Assembly F/L of Buming Inside Hole 8) Reel S, T Shaft (G381:Yellow) 9) Brake T Groove 1 4 2 4 3 5 5 6 2 6 9 3 7 Chassis (Bottom) 7 8 Chassis (Top) Side Gear Part Bottom inside Cam Part Gear Sector Cam & Gear Part Bottom Gear Cam Cam Part Guide Rack F/L Gear Rack F/L Press Cam Part Gear Assembly Up/D Gear Drive Stopper Part Plate Slider (Top) Gear Part Cam Part Guide Rail Bracket Side (L) Plate Slider (Bottom) Bracket Assembly Door 77 MECHANISM TROUBLESHOOTING GUIDE 1.Deck Mechanism A.
