1.
Check the area of your repair for unsoldered or poorly-soldered
connections.  Check the entire board surface for solder 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 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.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.

DCR-TRV270E/TRV280/TRV285E
1.
Self-diagnosis Function
When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder or LCD
screen 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 or LCD screen shows a 4-digit display consisting of an
alphabet 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.
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 “ON”, 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
[3] : Occurred third time
[5] : Occurred fifth time
[2] : Occurred second time
[4] : Occurred fourth time
[6] : Occurred the last time
3-3.
End of Display
Turning OFF the power supply will end the service mode display.
