About This Manual
Service policy
The LDK 7500 + LDK 5490 is a sophisticated camera
containingstate-of-the-artelectroniccomponentswhich
aredesignedtoprovidelong-lifeoperationwithout the
need for maintenance. With this in mind, the service
policyofThomsonBroadcastSolutions endeavours to
ensure that help will be quickly on hand in the unlikely
event of anything going wrong. The guiding principles
of the Thomson Broadcast Solutions first line
maintenance philosophy are speed and cost
effectiveness. First line maintenance is dedicated to
keeping your camera operational, despite a fault, by
module replacement and the replacement of minor
mechanical parts by the user.
Purpose of this manual
The provision of correct information is the first step in
ensuring the operational integrity of the camera.
Information on the operation of the camera is to be
found in the Operators’s Manual.
This technical manual is an integral part of the service
policy.Itensuresthatyouwillbeabletoinstallandset-
up your camera to meet the requirements of your
environment.Thisinformationontheinstallation of the
camera is contained in Section 2 of the manual. The
remaining sections of the manual provide first line
service information so that suitably qualified service
personnel can detect and repair faults, normally by
modulereplacement.
Becauseofthecomplexity of someofthecomponents,
second line service can only be carried out at the
specially equipped service centres and information
concerning second line maintenance is not supplied
in this manual.
Intended audience
The manual is intended as a guide to those with a
workingknowledgeof camera systemsandinstallation
techniques. The first line detection and repair of faults
requiresageneralknowledgeoftest andmeasurement
techniques.
Structure of this manual
The manual is divided into five different sections:
Section 1: Safety Instructions
Outlines the safety precautions that must be taken
when using the camera.
Section 2: Installation.
Givesinstructionsontheintegrationofthecamera into
the operating environment and the customization of
certainhardwarefunctions
Section 3: Replacements.
Gives information on the replacement of components
at first line level.
Section 4: Adjustments.
Contains the adjustment procedures to be followed to
obtain the best performance.

Identification and Status
To indicate the status of a drawing, a box with the
numbers 0 to 9 is shown in the bottom-right of the
drawing. The number that is crossed-out is the status
numberofthe drawing. For example, in the illustration
below, the status is 1.
A sticker is used on the units themselves to identify
them and to indicate their status. For example, in the
illustration below, the top line is the 12-digit number
that identifies the unit type.
The first four digits of the number on the second line
representadatecode(year,week);thenext four digits
represent the serial number for that week.
Thenumberinthegreyareaindicatesthestatusofthe
unit. The last two digits represent the number that will
be given to the next status. However, if these two
digits are contained in a box, then this is the current
status. For example, in the illustration above, the
current status of the unit is 01.
Line 1 392240700000
Line 2 123456AA0101
Line 3 VR/0123456789
Line 1
This is the code number of the printed circuit board
assembly (PCB).
Line 2
This is the serial number of the PCB. The first 6 digits
andthe2lettersareforinternaluse.Thelast four digits
reperesent the date of the manufacturing: wwyy.
Example:
123456AA1402 means the PCB is manufactured in
week 14 of the year 2002.
Line 3
This is the status of the PCB.
The digit after the first slash is the status. If there is
no number before the slash, it means that the status
is less than 10, a 1 before the slash means the status
is between 10 and 19, a 2 before the slash means
between 20 and 29 etc.
Example:
VR4567891012 means status 4
VR3/78901234 means status 37.
Example of LDK number:
LDK 4501/01 means 8926 450 10101
LDK 4500/00 means 8926 450 00001

Number (screened in PCB layout) of printed circuit
board assembly: 3922 411xxxxx (not a spare part).

Cathode ray tubes
Components marked on the circuit diagram are
criticalforsafetyandincludethosespecified to comply
withX-rayemission standardsforunitsusingcathode
ray tubes and those specified for compliance with
various regulations regarding spurious radiation
emission.
When servicing units that use cathode ray tubes
(CRTs), the cathode ray tubes themselves, the high
voltage circuits and related circuits are specifically
chosen so that they comply with recognized codes
pertaining to X-ray emission.
Consequently, when servicing, replace the cathode
ray tubes and other parts with specified parts only. Do
notattempttomodifythese circuitsasany unauthorized
modification can increase the high voltage value and
cause X-ray emission from the cathode ray tube.
Handle the cathode ray tube only when wearing
shatterproof goggles and after discharging the high
voltage completely.
