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.

1

Refer to 2-2 to remove the cabinet (R) cover (39E).

2

Refer to 2-3 to remove the F panel section.

3

Refer to 2-10 to remove the BT panel/EVF section.

4

Refer to 2-14 to remove the VA-118 board and Lens section.

5

Refer to 2-16 to remove the VC-311 board and Mechanism deck.

6

Refer to 2-17 to remove the MD frame assembly from the VC-311 board and Mechanism deck.

7

Disconnect the flexible board from CN2502 of VC-311 board.

8

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.

When problems occur while the unit is operating, the counter of the
viewfinder or LCD screen consists of an alphabet and 4-digit number,
which blinks at 3.2Hz. This 5-character display indicates the
“repaired by:”, “block” in which the problem occurred, and “detailed
code” of the problem.

Note: The “self-diagnosis display” data will be kept even if the lithium battery (BT5201 of CK-129 board) is removed.
