3-3-2. REMOVAL OF CCD
1) Unsolder the CCD sensor leads from the sensor PWB.
2) Take out the sensor PWB.
3) Remove the two screws (6), and remove the sensor holder and CCD sensor.
3-3-3. MOUNTING OF CCD
1) Place the lens unit upright (since the CCD sensor mount ID faces upward, care must be taken so as not to damage the
front lens of unit), put the crystal filter first and then the dust protection rubber into the CCD holder of lens unit. Set the
crystal unit with its thin side toward the lens unit.
2) PlacetheCCDsensorsothattheitsNo.1pinisattherightlower(Positioningholetobeatright),andputtheCCDsensor
into the CCD holder. For smooth and tight fitting, press the right lower part of back of CCD sensor, and then press the
left upper part.
Note: Pay attention to the direction of CCD sensor.
3) Place the sensor holder so that its two round markings be visible, and fix the sensor holder with the two screws ((6)LX-
HZ0013TAFF).
4) Mount the sensor PWB so that the CCD sensor leads go thorough the PWB holes.
5) Solder the CCD sensor lead to the sensor PWB.
Note: Take care not to apply excessive heat.

3-3. REPLACEMENT OF CCD SENSOR
3-3-1. BEFORE REPLACEMENT
1) The CCD image sensor is more sensitive to electrostatic breakage than C-MOS LSI. Therefore sufficient means to
prevent electrostatic damage must be taken when it is replaced.
•Ground the soldering iron.
•Ground also the human body, using the wrist strap(through an 1 Mohm resistor).
•Until the CCDsensor is mounted on the PWB, fit it to the conductive sponge, and short-circuit the foot lead.
2) Takeutmost care sothat the surface glassof CCD sensorandoptical filter arenotcontaminated and damaged.If any
contamination is found, for example fingerprint, wipe it off with silicon paper or clean chamois skin.
3) When replacing the CCD sensor, use the antistaic grounded soldring iron, and perform quickly soldering.

3-5. ADJUSTING THE Y/C, AUDIO AND LCD CIRCUITS ON MODELS WITHOUT A/V IN MODE
(A/V IN MODE SET-UP PRODUCE)
1) Set the switch of main body to VCR, and use the remote control (RRMCG0033TASA) for adjustment to turn on the
adjustment mode.
2) Set up the adjustment address (example : EEmode adjustment address 14). Once this address has been set up, the A/V
IN mode (test mode) is automatically brought and the images appear on the LCD display.
3) Now make the adjustments referring to the instruotions in the manual.
3-4. INITIAL SETTING OF E2PROM IC
3-4-1. E2PROM data alterable ways
1) Set the switch of main body to VCR, and use the remote control (RRMCG0033TASA) for adjustment to turn on the
adjustment mode.
2) VCR adjustment address setting.

After an objective address was established, play key is pushed and set.
In addition, numerical change uses a “REW” or “FF” key.
3) VCR adjustment data setting.

After an objective data was established, “PLAY” key is pushed and set.
4) When data of other address are changed successively, push “STOP” key, and please repeat operation to 5) from 3).
5) When SW of the substance is turned into off, data are written to E2PROM from systematic microcomputer.
3-4-2. IC702 (E2PROM)
When the IC702 has been replaced, make the following settings and adjustments.
1. Remove the backup battery (CR2025)
2. Turn power switch to CAMERA
3. Setting up the V ADJ mode as follows.
* After press the CONTINUE key, press the VCR ADJ key on service remote control (RRMCG0033TASA).

4. After setting the above data, clear the V ADJ mode and turn off the power by pull out the battery pack or DC cable.
Neglect about 30 seconds after turned of power, because data of address becomes effective after microcomputer is
reset.
Now the setting of data is completion.
Adjustments to follow
Make the system controller servo, VCR, and LCD adjustments according to their respective instructions.
3-4-3. CAMERA ADJUSTMENT
When the IC2 has been replaced, make the camera adjustment according to its instructions.

(1)Any cut washers, once removed for parts replacement or for other reason, must be replaced with new ones.
(2)The mechanism of this VCR does not involve any volume adjustment. If the specified range is not satisfied, either
cleaning or replacing the parts is required.
(3)Oils
a) Be sure to use the specified oils (different viscosity may cause troubles).
b) For the bearings, be sure to use oil that is free form dust and other foreign substances. (Dust or foreign substance
contained in the oil may cause wear or seizure of the bearings.)
c) A drop of oil represents the amount of oil which is held on the needle top as shown in the figure below.
(4)The circuit repair must be executed without removing the V frame.
(5)For operating themechanismalone, actuate it withthemotor. The terminal-to-terminalvoltagemust be DC4V orless.
(6)When installing the cassette control, press the part A shown below. Do not press other parts.

4-3. Mechanism checks and adjustments
The description given below relates to the general field services, but does not relate to the adjustment and replacement
that require high level equipments, jigs, and technical skills.
In order to maintain the initial characteristics of the machine, it is necessary to execute the maintenance and check and
to prevent damage to tapes and other parts. For adjustments which need jigs, be sure to use the jigs.
Notes and cautions
(1)For mechanism checks and adjustments, be sure to use the AC adapter as the power supply.
(2)For running the tape, be sure to install the cassette control ass’y in advance. (If the cassette control ass’y is to be
removed subsequently after its installation.)
4-3-1. Checking the reel disk height
(1)Remove the cassette control ass’y.
(2)Taking due care not to let the master plane touch the tape running areas such as the drum and the guide rollers,
position the master plane so that the two guides (A and B in the figure 1) are set in the holes of master plane, then
properly set it in the mechanism.
(3)Usingtheslidecallipersorthelike,checkthatthedistancefromtheuppersurfaceofmasterplanetothereelsupport
surface of the S/Tu reel disk is within the specified range.
Note:
When measuring, do not apply excessive force to the reel support surface of reel disk.
(4)If the measurement is not within the specified range, replace the reel disk ass’y.
(5)Check the items (2) to (4) above in the following two modes.
a) Standby mode
b) Playback (recording) mode

(1)Setthetorquecassette(8T-012)inposition,andcheckintheSP-moderecordingmode (taperecordedinSPmode)
that the torque at the tape taking-up side is within the standard range.
Standard of take-up torque for SP-mode recording (playback)
9 ±3 g.cm with ripples less than 4 g.cm
(If the torque ripples appear, read the center value of torque between the ripples.)
4-3-3. Checking and adjusting the back tension torque for playback (recording)
(1) Checking
1) Setthetorquecassette(8T-012)inposition,andcheckintheSP-moderecordingmode(taperecordedinSPmode)
that the torque at the tape supply side is within the standard range.
Standard of back tension torque for SP-mode recording (playback):
8 ±2 g.cm with ripples of less than 2 g·cm
(Torque ripple must be within 8 ±2g·cm)
(2) Adjustment
1) If the back tension torque is not within the standard range, adjust the tension spring hooking position. If the back
tensionistoo high, hook thespringinthe direction A. Ifthebacktension is too low,hookthespring in the direction
B.
Note:
1. After back tension torque adjustment be sure to check the tension pole position.
4-3-4. Checking and adjusting the tension pole position
(1) Check
When winding of P6-120 tape is started, check whether the tension pole is in the specified position against Si roller
as shown or not.
