DCR-TRV40/TRV40E/TRV50/TRV50E

1. Check the areaof your repairfor unsoldered or poorly-soldered

connections. Check the entireboard surface for soldersplashes

and bridges.

2. Check the interboard wiring to ensure that no wires are

"pinched" or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly

transistors, that were installed during a previous repair. Point

them out to the customer and recommend their replacement.

4. Look for parts which,through functioning, show obvious signs

of deterioration. Point them out to the customer and

recommend their replacement.

5. Check the B+ voltage to see it is at the values specified.

6. Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270˚C

during repairing.

• Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering

or unsoldering.

Unleaded solder

Boards requiring use of unleaded solder are printed with the lead-

free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

•Unleaded solder melts at a temperature about 40°C higher than

ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350°C.

Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

•Strong viscosity

Unleaded solder is more viscous (sticky, less prone to flow) than

ordinary solder so use caution not to let solder bridges occur such

as on IC pins, etc.

•Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer.

1-1. SERVICE NOTE

1. POWER SUPPLY DURING REPAIRS

In this unit, about 10 seconds after power is supplied to the battery terminal using the regulated power supply (8.4V), the power is shut off so

that the unit cannot operate.

This following two methods are available to prevent this. Take note of which to use during repairs.

Method 1.

Use the AC power adaptor (AC-L10,AC-VQ800 etc.).

Method 2.

Connect the servicing remote commander RM-95 (J-6082-053-B) to the LANC jack, and set the commander switch to the “ADJ” side.

2Refer to 2-4 to remove the front panel section.

3Refer to 2-6, 2-7 to remove the cabinet (R) section.

4Refer to 2-8 to remove the BT panel assembly.

5Refer to 2-9 to remove the BT-003 board. (DCR-TRV50/

6Refer to 2-10 to remove the external connector and shoe base.

7Refer to 2-11, 2-12 to remove the EVF block.

8Refer to 2-17 to remove the DD-176 board.

9Remove the mechanism deck and VC-283 board.

4. DISCHARGING OF THE FLASHLIGHT POWER SUPPLY CAPACITOR

The power supply capacitor of the flash unit is charged up to the maximum 300V potential.

There is a danger of electric shock by this high voltage when the capacitor is handled by hand. The electric shock is caused by the charged

voltage which is kept without discharging when the main power of the unit is simply turned off. Therefore, the remaining voltage must be

discharged as described below.

4-1. PREPARING THE SHORT JIG

To preparing the short jig. a small clip is attached to each end of a resistor of 1kΩ/1W (1-215-869-11).

Wrap insulating tape fully around the reads of the resistor to prevent electric shock.

4-2. DISCHARGING THE CAPACITOR

1Remove the power supply (Battery orAC power adaptor).

2Open the cassette lid (grip cabinet).

3Remove the two screws with which the grip cover is fixed.

4Remove the grip cover.

5Remove the insulation sheet.

6Short circuit between 3and #terminal of the capacitor with the short jig about 10 seconds.

Note for installing the grip cover

When installing the grip cover, insert it in the claws of the grip cabinet.

1-2. SELF-DIAGNOSIS FUNCTION

1. SELF-DIAGNOSIS FUNCTION

When problems occur while the unit is operating, the self-diagnosis

function starts working, and displays on the viewfinder, LCD screen

or LCD window what to do. This function consists of two display;

self-diagnosis display and service mode display.

Details of the self-diagnosis functions are provided in the Instruction

manual.

2. SELF-DIAGNOSIS DISPLAY

When problems occur while the unit is operating, the counter of the

viewfinder, LCD screen or LCD window consists of an alphabet

and 4-digit numbers, which blinks at3.2 Hz.This5-character display

indicates the “repaired by:”, “block”in which the problem occurred,

and “detailed code”of the problem.

3. SERVICE MODE DISPLAY

The service mode display shows up to six self-diagnosis codes shown in the past.

3-1. Display Method

While pressing the “STOP”key, set the switch from OFF to “VCR”, and continue pressing the “STOP”key for 5 seconds continuously. The

service mode will be displayed, and the counter will show the backup No. and the 5-character self-diagnosis codes.

3-2. Switching of Backup No.

By rotating the control dial, past self-diagnosis codes will be shown in order. The backup No. in the [ ] indicates the order in which the

problem occurred. (If the number of problems which occurred is less than 6, only the number of problems which occurred will be shown.)

[1] : Occurred first time [4] : Occurred fourth time

[2] : Occurred second time [5] : Occurred fifth time

[3] : Occurred third time [6] : Occurred the last time

3-3. End of Display

Turning OFF the power supply will end the service mode display.
