1. Safety
1.1 Safety Instructions
WARNING:Before Removing/Replacing any projector components, turn off the Main Power Switch and un-
plug the Main AC power cable.
Safety Instructions
1. Before returning an instrument to the customer, always make a safety check of the entire instrument, including, but not limited
to, the following items:
a) Be sure that no built-in protective devices are defective and/or have been defeated during servicing. (1) Protective shields
are provided on this chassis to protect both the technician and the customer. Correctly replace all missing protective shields,
including any removed for servicing convenience. (2) When reinstalling the chassis and/or other assembly in the cabinet,
be sure to put back in place all protective devices, including, but not limited to, insulating materials, barriers, covers/shields,
and isolation resistor/capacitor networks. Do not operate this instrument or permit it to be operated without all protective
devices correctly installed and functioning. Servicers who defeat safety features or fail to perform safety checks may be
liable for any resulting damage.
b) Be sure that there are no cabinet openings through which an adult or child might be able to insert their fingers and contact a
hazardous voltage. Such openings include, but are not limited to, (1) excessively wide cabinet ventilation slots, and (2) an
improperly fitted and/or incorrectly secured cover panels.
c) Leakage Current Hot Check. With the instrument completely reassembled, plug the AC line cord directly into a 220 V AC
outlet (Do not use an isolation transformer during this test). Use a leakage current tester or a metering system that complies
with American National Standards Institute (ANSI) C101.0 Leakage Current for Appliances and Underwriters Laboratories
(UL) 1410, (50.7). With the instrument AC switch first in the on position and then in the off position, measure from a known
earth ground (metal waterpipe, conduit, etc.) to all exposed metal parts of the instrument (antennas, handle bracket, metal
cabinet, screwheads, metallic overlays, control shafts, etc.). especially any exposed metal parts that offer an electrical
return path to the chassis. Any current measured must not exceed 1.5 mA. Reverse the instrument power cord plug in the
outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL
SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE INSTRUMENT TO THE CUSTOMER OR
BEFORE CONNECTING ACCESSORIES.

d) Ultraviolet Radiation exposure - Warning: This lamp can cause serious skin burn and eye inflammation from shortwave
ultraviolet radiation if not operated in enclosed fixtures. DO NOT operate this lamp in a fixture with a missing or broken lens
cover.
e) Ozone: Operating lamp generates ozone gas which is harmful to the respiratory system. Therefore the lamp should be
operated in adequately ventilated equipment.
2. Read and comply with all caution and safety-related notes on or inside the projector cabinet or on the projector chassis, or on
the picture tube.
3. Design Alteration Warning - Do not alter or add to the mechanical or electrical design of this apparatus. Design alterations and
additions, including, but not limited to, circuit modifications and the addition of items such as auxiliary audio and/or video output
connections, might alter the safety characteristics of this apparatus and create a hazard to the user. Any design alterations
or additions may void the manufacturer’s warranty and may make you, the servicer responsible for personal injury or property
damage resulting therefrom.

1. Safety
4. Lamp explosion Protection Warning – The lamp in this projector operates with a high internal pressure and there is a slight risk
that the lamp may explode, particularly if it is used beyond its rated life. Do not remove, install, or otherwise handle the lamp
in any manner without first putting on shatterproof goggles equipped with side shields. People not so equipped must be kept
safely away while lamps are handled. Keep the lamp away from your body. For continued explosion protection, replace the
lamp only with one of the same type number. Always replace the lamp before the rated life time.
5. Hot Chassis Warning - This projector chassis has two ground systems: the primary ground system is formed by the negative
voltage of the rectified mains (power) and is only used as a reference in primary circuits; the secondary ground system is
connected to earth ground via the earth conductor in the mains (power) lead. Separation between primary and secondary
circuits is performed by the safety isolation transformers. Components bridging this transformers are also safety components
and must never be defeated or altercated. All user-accessible conductive parts must be connected to earth ground, or are kept
at SELV (Safety Extra Low Voltage).
6. Observe original lead dress. Always inspect in all areas for pinched, out-of-face, or frayed wiring. Do not change spacing
between components, and between components and the printed-circuit board. Check AC power cord for damage. Take extra
care to assure correct lead dress in the following areas:
a) near sharp edges
b) near thermally hot parts - be sure that leads and components do not touch thermally hot parts
c) the AC supply
d) high voltage
7. Components, parts, and/or wiring that appear to have overheated or are otherwise damaged should be replaced with compo-
nents, parts, or wiring that meet original specifications. Additionally, determine the cause of overheating and/or damage and, if
necessary, take corrective action to remove any potential safety hazard.
8. PRODUCT SAFETY NOTICE - Many electrical and mechanical parts have special safety-related characteristics some of which
are often not evident from visual inspection, nor can the protection they give necessarily be obtained by replacing them with
components rated for higher voltage, wattage, etc. Use of a substitute replacement that does not have the same safety charac-
teristics as the recommended replacement part in BARCO service data parts list might create shock, fire, and/or other hazards.
Product Safety is under review continuously and new instructions are issued whenever appropriate. For the latest information,
always consult the appropriate current BARCO service literature.
9. Do not spray chemical on or near this instrument or any of its assemblies.
10. Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity.
Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated
circuits and some field-effect transistors and semiconductor "chip" components. The following techniques should be used to
help reduce the incidence of component damage caused by static electricity:
a) Immediately before handling any semiconductor-equipped assembly, drain off any electrostatic charge on your body by
touching a known earth ground. Wear a commercially available high impedance discharging wrist strap device.
b) After removing an electrical assembly equipped with ES devices, place the assembly on a static dissipative surface such as
a 3M No 8210 table mat, to prevent electrostatic charge buildup or exposure of the assembly.
c) Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.
d) Do not remove a replacement ES device from its protective package until immediately before you are ready to install it
(Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminium foil or
comparable conductive material).
e) Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material
to the chassis or circuit assembly into which the device will be installed. CAUTION: Be sure no power is applied to the chassis
or circuit, and observe all other safety precautions.
f) Minimize bodily motions when handling unpacked replacement ES devices (Otherwise harmless motion such as the brush-
ing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to
damage an ES device).

About this chapter
This chapter enumerates all possible error codes which can appear on the local LCD display of the FLM projector. The code dis-
played is preceded by a “-”signincaseofawarning or a “+”signincaseofarealerror. Note that not all codes have a warning
and an error state. Some only have an error state, others have only a warning state. In case of a “warning” the projector remains
to operate. Nevertheless, it is recommended to solve the problem which causing the “warning” as soon as possible otherwise, the
“warning” state may turn into an “error” state which will switch off the projector consequently.
The codes are placed in ascending order to make it easier to look up the code and find an appropriate solution.

3.1 1000 →1017 : Lamp parameters related errors
Error 1000 →1017 : “Wrong lamp parameters”
These error codes may appear during the start up of the projector.
Situation Solution
Wrong lamp house detected in lamp
compartment of the projector.
Replace the lamp house with a compatible lamp house for this projector. Note that a 3,5
kW lamp is not suitable for the FLM R20+ or FLM HD14.
No communication with the lamp
house. • Check if the blue socket (ref A image 3-1) of the lamp house is not damaged.
Warning: Never attempt to repair the lamp house. Reinstall a new lamp house and
send the damaged lamp house back to factory for repair.
• Check if the blue socket (ref B image 3-1) in the upper left corner of the lamp
compartment is not damaged.
• Check the wiring at the rear side of the blue socket (ref C image 3-2) inside the
projector. The rear side of the blue socket in the projector is visible after removal of
the left side cover (light processor side).
• Check if the wire unit coming from the blue socket in the lamp compartment
is plugged into its socket (ref D image 3-2) on the backplane behind the input
& communication unit.

3. Troubleshooting
3.2 1692 →1699 : Formatter related errors
Error 1692 : “Form. PWRGood”
Situation Solution
Formatter “Power Good" signal not
OK. The local power supplies on
the Formatter Interface Board fails.
The orange LED “PWRGood” (ref
Aimage3-3&image3-4)onthe
Formatter Interface Board remains
off.
The status LED’s of the Formatter
Interface Board (FIB) are visible
through the filter grid behind the
front filter. So, you have to remove
the projector front cover and the
front filter first to see the LED’s on
the FIB.
• Check if all wire units between the Formatter Interface Board and the three
formatter boards are not damaged. A damaged wire unit can cause a short circuit
in the local power supply of the Formatter Interface Board.
• Check if none of the pins of the connectors on the FIB or formatter boards are
bend over.
• Replace the Formatter Interface Board.
• If the problem remains contact Barco for further instructions. The formatter boards
are malfunctioning and have to be replaced at the factory.
