Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
The mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
Screws adjacent to mark on product are used for disassembly.
Reference Nos. indicate the pages and Nos. in the service manual for the base model.
For the applying amount of lubricants or glue, follow the instructions in this manual.
(In the case of no amount instructions, apply as you think it appropriate.)
When ordering resistors, first convert resistance values into code form as shown in the following examples.
•
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).
560 Ω→56 × 10
47k Ω→47 × 10
0.5 Ω→R50 ..................................................................................... RN2H
1 Ω→1R0 ..................................................................................... RS1P
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

2. GENERAL INFORMATION
2.1 DIAGNOSIS OF THE HDMIB ASSY
A
*This flowchart shows how to confirm the output from the HDMI block on the basis that an external input signal to the L1
connector is through-output from the analog output connector properly.
1. In a case when only the HDMI video is not outputted
Connect the unit to a DVI monitor that is provided
with the HDCP function (HDMI-DVI conversion
connector required), or to a monitor that supports HDMI.
Set the input setting to L1.
Input an external PAL signal to L1.
4
B
Is the HDMI indicator
of the unit lit?
No
YES
Is an image
properly
displayed?
YES
to AA
C
With the aid of an oscilloscope, check IC201 for the
points listed below. (Only checking with a PAL signal
is enough. Checking with an NTSC signal is not required):
• R242 (QCLK: 27 MHz/74.25 MHz/148.5 MHz @PAL)
From the following points, a 3.3-V swing signal must be output:
• R244 (H sync)
• R245 (V sync)
• R121-R126 (Video lines)
No
Are all the signals
mentioned above
output?
YES
No
Check the soldering at IC401 and IC201.
*Also check if there is pattern peeling if the
D
E
unit has undergone repair or rework.
Check the communication between IC401 and IC101.
• First check the soldering of IC101.
* Also check if there is pattern peeling if the unit has
undergone repair or rework.
• Next, with the aid of an oscilloscope, check IC401
for the points listed below.
In a case where the set number of pixels is 480i/576i:
• R149 (CLKO: 27MHz@PAL)
From the following points, a 3.3-V swing signal must
be output:
• R151 (H sync)
• R150 (V sync)
• R147, R148 (Video line)
In a case where the set number of pixels is 480p/576p
or larger:
• R150 (QCLK: 27MHz@PAL)
From the following points, a 3.3-V swing signal must
be output:
• R161 (H sync)
• R162 (V sync)
• R152, R153, R154, R155 (Video line: Y)
• R156, R157, R158, R159 (Video line: C)
It is most likely that IC201 and the
subsequent parts are in failure.
Check the soldering of the parts
listed below:
• IC201 itself
• L201-L204, JA201
Enter HDMI Service mode
then check if the HDMI indicator is lit.
Is the TMDS signal
properly output in
HDMI Service mode?
No
Is the FFC cable
properly connected
to CN101?
Yes
No
Reconnect the FFC cable and
CN101 correctly then repeat
the steps of this flowchart
from the beginning.
Are all the signals
mentioned above
properly output?
Check if the LSI power
at IC201 is active:
• 3.3-V system: R202
• 1.8-V system: R201
No
Replace the fuse on the
Power Assy.It is most
likely that inappropriate
connection of the FFC
cable caused short-circuiting
and that the fuse on the
Power Assy was blown.
Yes
Repeat the steps
of this flowchart
from the beginning.
Yes
It is most likely that
IC201 is in failure:
• Check the soldering
of IC201.
• Rework on IC201.
No
• Check if the FFC cable is properly
connected to CN101. (Also check the
connection on the DVDM Assy.)
F
8
• Rework on IC102.
• Rework on IC501.
If the condition does not improve, the
circuitry on the DVDM side is in failure.
DVR-940HX-S
YES
Repeat the steps
of this flowchart
from the beginning.

AA
A
The monitor owned by the user may not be compatible
with this unit.
Is a correct picture displayed when the monitor owned by
the user is connected with this unit using a 5-meter cable
made by JAE?
Ye s N o
B
The cable used by the user is in failure.
Is a momentary correct picture and a fully black or a
snowy screen alternately displayed? Or, another
symptom?
Confirm the manufacturer and model number, and check
symptoms in the following steps, then refer to similar
case examples that happened in the past. In some
cases, upgrading the software/firmware of this unit may
resolve the problem.
If there is no measure, ask us for product
quality information.
1 Does the symptom change when the HDMI cable between the monitor and recorder is disconnected then reconnected?
2 With the HDMI cable between the monitor and this unit connected, if the power to the monitor is turned off then back on
again, does the symptom change?
3 Tu rn off the power to both the recorder and monitor. Then, turn on the monitor, then after 30 seconds, turn on the
recorder. Does the symptom change?
4 Is the HDMI LED lit, unlit, or flashing?
C
D
5 What is the picture on the screen like? A fully black, snowy, combination of the both, or other (a fully green or pink

6 Does the symptom change if the length of the cable (made by JAE) is different?
7 Are some spots missing by dots (missing pixels) on the screen? If so, there may be problems in the length or quality of
the cable or the reception capacity of the monitor. Check if the symptom disappears when a 5-meter or less cable made
by JAE is used.

Is a DVI device connected (with a DVI device, only the video signal is output, and no
sound is output)? Is an HDMI device that does not support the audio signals
connected?
No (Checking of the S/PDIF path)
Set the Dolby Digital output setting in "Audio
Output" of the home menu to PCM. Play back the
Dolby Digital audio signal of a DVD. Is the audio
signal correctly output from the HDMI and coaxial
output (S/PDIF)?
HDMI: No
S/PDIF: Yes
There may be a
problem with the
coaxial output
circuit.
In a case where S/PDIF
was "No" in the above
step (analysis in a case
where HDMI was "No")
Measure the signal at R229 of
IC201 (S/PDIF) with an
oscilloscope, using a probe, to
check if the signal is correct.
No

Measure the signal at
R*** (Note 1) (S/PDIF)
with an oscilloscope,
using a probe, to check
if the signal is correct.
There may be a failure
in the MAIN ASSY
(S/PDIF).
Play back a CD. Are the
HDMI and analog audio
signals correctly output?
HDMI: No
S/PDIF: No
No
Measure the signal at R229 of
IC201 (S/PDIF) with an
oscilloscope, using a probe, to
check if the signal is correct.
No (Checking of the AMCK_HDMI, DATA, LRCK,
and BCK paths)
Measure the signal at 1 Pin 5 of IC201
(AMCLK_HDMI) and 2 Pins 10, 11, and
12 of IC201 (DATA, LRCK, and BCK) with
an oscilloscope, using a probe, to check if
the signal is correct.

stage.
No
In a case where the analog audio
signal is not correctly output for
reason
(Analysis in a case where
HDMI was "No")
There may be a failure in

Check the soldering of signal
lines (incl. IC pins), short-

of wires, and if a part shows
a problem, replace the part.

Replacement of IC201 HDMI
Tr ansmitter: There may be a
problem in the S/PDIF input
block. (After checking that the
soldering is all right, replace
the IC. If soldering is
defective, repair it and check
if the symptom disappears.)

÷ When servicing this model, some service procedures may reset the customer settings
to the factory default settings. Make sure to explain this to the customer.
An HDD (Hard Disc Drive) is mounted in this product.
The HDD is a precision instrument very vulnerable to shock and electrostatic charges. Please read
"7.3 Cautions on Handling the HDD" in this manual and exercise sufficient caution when handling the
HDD itself, as well as the product with the HDD built in.
When an HDD becomes defective and inoperable, restoration of the user's data recorded on the HDD,
or copying of the user's recorded data to other media (such as a new HDD) is totally impossible.
Before servicing, OBTAIN THE USER'S PRIOR CONSENT to that effect.
The user must be made aware that all recorded data are deleted if the HDD is intialized.

Additional Laser Caution
1. The ON/OFF(ON:low level,OFF:high level) status of the
CLAMP signals for detecting the loading state are detected
by the drive CPUs, and the design prevents laser diode
oscillation when the CLAMP signal turns OFF.
In normal operation, if no disc is clamped, the laser diode
oscillation is disabled.
However, the interlock does not always operate in the test
mode.
2. When the cover is opened, close viewing of the objective
D
lens with the naked eye will cause exposure to a Class 3A
laser beam.
