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

Note: The “self-diagnosis display” data will be backed up by the coin-type lithium battery (CF-2500 block BT001). When the

CF-2500 block is disconnected, the “self-diagnosis display” data will be lost by initialization.

When problems occur while the unit is operating, the counter of the
viewfinder or Display window 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.

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

While pressing the “STOP” key, set the switch from OFF to “VTR or PLAYER”, 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.

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

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

Inspect the lens block focus reset sensor (Pin qd of CN1551 of
VC-276 board) when focusing is performed when the focus ring is
rotated in the focus manual mode and the focus motor drive circuit
(IC1553 of VC-276 board) when the focusing is not performed.

Inspect the lens block zoom reset sensor (Pin qs of CN1551 of
VC-276 board) when zooming is performed when the zoom switch
is operated and the zoom motor drive circuit (IC1553 of VC-276
board) when zooming is not performed.

Inspect pitch angular velocity sensor (SE301 of SE-032 board)
peripheral circuits.

Inspect yaw angular velocity sensor (SE302 of SE-032 board)
