SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINEWITH
MARK 0ON THE SCHEMATIC DIAGRAMS AND INTHE PARTS
LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE
COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS
APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS
PUBLISHED BY SONY.
ATTENTION AU COMPOSANT AYANT RAPPORT
À LA SÉCURITÉ!
LES COMPOSANTS IDENTIFÉS PAR UNE MARQUE 0SUR LES
DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT
CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE
REMPLACER CES COMPOSANTS QUE PAR DES PIÈSES SONY
DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU
DANS LES SUPPÉMENTS PUBLIÉS PAR SONY.
1. Check the areaof your repair for unsoldered or poorly-soldered
connections. Checkthe entire board surfaceforsolder splashes
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 partswhich, through functioning, show obvioussigns
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.
CAUTION
Dangerofexplosionifbatteryisincorrectly replaced.
Replace only with the same or eqivalent type.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.

SERVICE NOTE
DCR-TRV940/TRV940E/TRV950/TRV950E
COVER
COVER
The charging capacitor of the Flash unit is charged up to the
maximum 300 V potential.
There is a danger of electric shock by this high voltage when the
battery 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.
1-2-1. Preparing the Short Jig
To preparing the short jig, a small clip is attached to each end of a
resistor of 1 kΩ/1 W (1-215-869-11).
Wrap insulating tape fully around the leads of the resistor to prevent
electrical shock.
1 kΩ/1 W
Wrap insulating tape.
1-2-2. Discharging the Capacitor
Short-circuit between the positive and the negative terminals of
charged capacitor with the short jig about 10 seconds.
1-1. NOTE FOR REPAIR
Make sure that the flat cable and flexible board are not cracked of
bent at the terminal.
Do not insert the cable insufficiently nor crookedly.
Cut and remove the part of gilt
which comes off at the point.
(Be careful or some
pieces of gilt may be left inside)
When remove a connector, don’t pull at wire of connector.
It is possible that a wire is snapped.
When installing a connector, don’t press down at wire of connector.
It is possible that a wire is snapped.

1-3. 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.
These 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.
1-4. TO TAKE OUT A CASSETTE WHEN NOT EJECT (FORCE EJECT)
1Refer to 2-2 to remove the cabinet (R) block assembly.

1-5. NOTES ON HANDLING THE LASER DIODE
[LASER UNIT (D501)]
The laser diode may suffer electrostatic breakdown because of the
potential difference generated by the charged electrostatic load, etc.
on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.
1-5-1. Soldering Conditions of Laser Unit (D501)
Temperature of 350 °C
the Soldering Iron
Time to Solder 3 seconds
Interval to Solder Next terminal is soldered after
waiting for 1 second
Note: Adjustment is needed when laser unit (D501) is replaced.
Refer to “20. Hologram AF Output Adjustment”and “21.

1-6. SELF-DIAGNOSIS FUNCTION
1-6-1. Self-diagnosis Function
When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder or Display
window what to do. This function consists of two display; self-
diagnosis display and service mode display.
Detailsofthe self-diagnosis functions are providedin the Instruction
manual.
1-6-2. Self-diagnosis Display
When problems occur while the unit is operating, the counter of the
viewfinder or Display window shows a 4-digit display consisting
ofanalphabet and numbers,which blinks at 3.2 Hz.This 5-character
display indicates the “repaired by:”, “block”in which the problem
occurred, and “detailed code”of the problem.
1-6-3. Service Mode Display
The service mode display shows up to six self-diagnosis codes shown in the past.
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.
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. End of Display
Turning OFF the power supply will end the service mode display.
