VCR TEST TAPE INTERCHANGEABILITY TABLE

There are two types of the new allgnment tape CH-1B (for NTSC) and CH-2 (for PAL). On each tape four signals (1)-(4) are recorded for the times and in the order shown below.

(1) : 8min. → (2) : 2min. → (3) : 5min. → (4) : 5min.

The TTV-MP1 (for M-PAL), TTV-MS1 (for MESECAM) and TTV-S1 (for SECAM) allgnment tapes have the same contents as the previous tapes.

• Adjustment Procedure

1. Insert the PAL SP Test Tape (TTV-P1) and play. Note - Adjust the distance of X, pressing the Tracking(+) or Tracking(-) when the “ATR” is blink after the

PAL SP Test Tape is inserted.

2. Connect the CH1 of the oscilloscope to the H/SW (W5D2, W5D3) and CH2 to the Video Out for the VCR.

3. Trigger the mixed Video Signal of CH2 to the CH1 H.SW (W5D2, W5D3), and then check the distance (time difference), which is from the selected A(B) Head point of the H.SW(W5D2, W5D3) signal to the starting point of the vertical synchronized signal, to 6.5H ± 0.5H (416µs, 1H=64.0µs).

Purpose:To determine if the Mechanism is in the correct position, when a Tape is ejected.

1.Mechanism Alignment Position Check

1) Turn the Power S/W on and eject the Cassette by pressing the Eject Button.

2) Remove the Top Cover and Plate Assembly Top, visually check if the Gear Cam Hole is aligned with the Chassis Hole as below Fig. C-2.

3) IF not, rotate the Shaft of the Loading Motor to either Clockwise or Counterclockwise until the Alignment is as below Fig. C-2.

4) Remove the Screw which fixes the Deck Mechanism and Main Frame and confirm if the Gear Cam is aligned with the Gear Drive as below Fig. C-1(A).

5) Confirm if the Mode S/W on the Main P.C.Board is aligned as below Fig. C-1(B).

6) Remount the Deck Mechanism on the Main P.C.Board and check each operation.

DECK MECHANISM ADJUSTMENT

Purpose: To insure smooth Transport of the Tape during each Mode of Operation.

If the Tape Transport is abnormal, then check the Torque as indicated by the chart below.

2. Preparation for Adjustment (To set the Deck Mechanism to the Loading state without inserting a Cassette Tape).

1) Unplug the Power Cord from the AC Outlet.

2) Disassemble the Top Cover and Plate Assembly Top.

3) Plug the Power Cord into the AC Outlet.

4) Turn the Power S/W on and push the Lever Stopper (L),(R) of the Holder Assembly CST to the back for

Loading the Cassette without Tape. Cover the Holes of the End Sensors at the both sides of the Bracket Side(L) and Bracket Assembly Door to prevent a light leak. Then The Deck Mechanism drives to the Stop Mode. In this case, The Deck Mechanism can accept inputs of each mode, however the Rewind and Review Operation can not be performed for more than a few seconds because the Take-up Reel Table is in the Stop State and can not be detected the Reel Pulses.

3. Checking Torque

The Values are measured by using a Torque Gauge and Torque Gauge Adaptor with the Torque Gauge affixed.

The Torque reading to measure occurs when the Tape abruptly changes direction from Fast Forward of Rewind Mode, when quick bracking is applied to both Reels.

Adjustment Procedure

1) Confirm if the Tape runs along the Tape Guide Line of the Lower Drum.

2) If the Tape runs the Bottom of the Guide Line, turn the Guide Roller Height Adjustment Screw to Clockwise direction.

3) If it runs the Top, turn to Counterclockwise direction.

4) Adjust the Height of the Guide Roller to be guided to the Guide Line of the Lower Drum from the Starting and

Ending Point of the Drum.

Purpose: To regulate the Height of the Tape so that the Bottom of the Tape runs along the

The following faults can be remedied by cleaning and oiling. 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.

MAINTENANCE/INSPECTION PROCEDURE

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.

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.

(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.

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.

2 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.
