corrected before returning the monitor to the owner.
the following safety checks:
1. Inspect all lead dress to make certain that leads are
not pinched, and check that hardware is not lodged
between the chassis and other metal parts in the
receiver.
2. Inspect all protective devices such as non-metallic
control knobs, insulation materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacitor networks, mechanical
insulators and etc.

» Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15µF capacitor in series
with all exposed metal cabinet parts and a known
earth ground, such as electrical conduit or electrical
ground connected to an earth ground.
Many electrical and mechanical parts in television have
special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarily increased by using replacement components
rated for higher voltage, wattage and etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
and shaded areas in the
Schematic Diagrams.
For continued protection, replacement parts must be
identical to those used in the original circuit.
The use of a substitute replacement parts which do not
have the same safety characteristics as the factory
recommended replacement parts shown in this service
manual, may create shock, fire or other hazards.

VERIFICA TIONS CONTRE L'INCEN-DIE ET
LE CHOC ELECTRIQUE
Avant de rendre le récepteur à l'utilisateur, effectuer
les vérifications suivantes.
1. Inspecter tous les faisceaux de câbles pour s'assurer
que les fils ne soient pas pincés ou qu'un outil ne soit
pas placé entre le châssis et les autres pièces
métalliques du récepteur.
2. Inspecter tous les dispositifs de protection comme les
boutons de commande non-métalliques, les isolants,
le dos du coffret, les couvercles ou blindages de réglage
et de compartiment, les réseaux de résistancecapacité, les isolateurs mécaniques, etc.
3. S'assurer qu'il n'y ait pas de danger d'électrocution en
vérifiant la fuite de courant, de la facon suivante:
• Brancher le cordon d'alimentation directem-ent à une
prise de courant de 110-240V. (Ne pas utiliser de
transformateur d'isolation pour cet essai).
• A l'aide de deux fils à pinces, brancher une résistance
de 1.5 kΩ 10 watts en parallèle avec un condensateur
de 0,15µF en série avec toutes les pièces métalliques
exposées du coffret et une terre connue comme une
conduite électrique ou une prise de terre branchée à
la terre.
• Utiliser un voltmètre CA d'une sensibilité d'au moins
5000Ω/V pour mesurer la chute de tension en travers
de la résistance.
• Toucher avec la sonde d'essai les pièces métalliques
exposées qui présentent une voie de retour au châssis
(antenne, coffret métallique, tête des vis, arbres de
commande et des boutons, écusson, etc.) et mesurer
la chute de tension CA en-travers de la résistance.
T outes les vérifications doivent être refaites après avoir
inversé la fiche du cordon d'alimentation. (Si nécessaire,
une prise d'adpatation non polarisée peut être utilisée
dans le but de terminer ces vérifications.)
Tous les courants mesurés ne doivent pas dépasser
0,5 mA.
Dans le cas contraire, il y a une possibilité de choc
électrique qui doit être supprimée avant de rendre le
récepteur au client.
De nombreuses pièces, électriques et mécaniques, dans
les téléviseurs présentent des caractéristiques spéciales
relatives à la sécurité, qui ne sont souvent pas évidentesà vue. Le degré de protection ne peut pas être
nécessairement augmentée en utilisant des pièces de
remplacement étalonnées pour haute tension,
puissance, etc.
Les pièces de remplacement qui présentent ces
caractéristiques sont identifiées dans ce manuel; les
pièces électriques qui présentent ces particularités sont
identifiées par la marque " å " et hachurées dans la
liste des pièces de remplacement et les diagrammes
schématiques.
Pour assurer la protection, ces pièces doivent être
identiques à celles utilisées dans le circuit d'origine.
L'utilisation de pièces qui n'ont pas les mêmes
caractéristiques que les pièces recommandées par
l'usine, indiquées dans ce manuel, peut provoquer des
électrocutions, incendies, radiations X ou autres
accidents.

SAFETY PRECAUTIONS
NOTICE :Comply with all cautions and safety related notes
located on or inside the cabinet and on the chassis.
The following precautions should be observed :
1. When service is required, even though the PDP UNIT an
isolation transformer should be inserted between the power
line and the set in safety before any service is performed.
2.When replacing a chassis in the set, all the protective
devices must be put back in place, such as barriers,
nonmetallic knobs, adjustment and compartment
covershields, isolation resistor-capacitor, etc.
3. When service is required, observe the original lead dress.
Extra precaution should be taken to assure correct lead
dress in the high voltage circuitry area.
4. Always use the manufacture's replacement components.
Especially critical components as indicated on the circuit
diagram should not be replaced by other manufacture's.
Furthermore where a short circuit has occurred, replace
those components that indicate evidence of overheating.
5. Before returning a serviced set to the customer, the service
technician must thoroughly test the unit to be certain that it
is completely safe to operate without danger of electrical
shock, and be sure that no protective device built into the
set by the manufacture has become defective, or
inadvertently defeated during servicing. Therefore, the
following checks should be performed for the continued
protection of the customer and service technician.
6. Perform the following precautions against unwanted
radiation and rise in internal temperature.
• Always return the internal wiring to the original styling.
• Attach parts (Gascket, Ferrite Core, Ground, Rear Cover,
Shield Case etc.) surely after disassembly.
7. Perform the following precautions for the PDP panel.
• When the front case is removed, make sure nothing hits
the panel face, panel corner, and panel edge (so that the
glass does not break).
• Make sure that the panel vent does not break. (Check
that the cover is attached.)
• Handle the FPC connected to the panel carefully.
Twisting or pulling the FPC when connecting it to the
connector will cause it to peel off from the panel.
8. Pay attention to the following.
• Be sure to wire the fan. If the fan does not work, the
temperature will rise and cause the protection circuit to
operate.
• When the front case is removed, infrared ray is radiated
and may disturb reception of the remote control unit.
• Pay extreme caution when the front case and rear panel
are removed because this may cause a high risk of
disturbance to TVs and radios in the surrounding.

Leakage Current Cold Check
With the AC plug removed from an AC power source, place
a jumper across the two plug prongs. Turn the AC power
switch on. Using an insulation tester (DC 500V), connect one
lead to the jumpered AC plug and touch the other lead to each
exposed metal part (input/output terminals, screwheads,
metal overlays, control shafts, etc.), particularly any exposed
metal part having a return path to the chassis. Exposed metal
parts having a return path to the chassis should have a
minimum resistor reading of 0.3MΩ and a maximum resistor
reading of 5MΩ. Any resistor value below or above this range
indicates an abnormality which requires corrective action.
Exposed metal parts not having a return path to the chassis
will indicate an open circuit.
Leakage Current Hot Check
Plug the AC line cord directly into an AC power source (do not
use an isolation transformer for this check).
Turn the AC power switch on.
Using a "Leakage Current Tester (Simpson Model 229
equivalent)", measure for current from all exposed metal
parts of the cabinet (input/output terminals, screwheads,
metal overlays, control shaft, etc.), particularly any exposed
metal part having a return path to the chassis, to a known
earth ground (water pipe, conduit, etc.). Any current measured
must not exceed 0.5mA.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in SHARP set have
special safety related characteristics. These are often not
evident from visual inspection nor the protection afforded by
them necessarily can be obtained by using replacement
components rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this Service Manual.
Electrical components having such features are identified by
marking with a
this Service Manual.
The use of a substitute replacement component which dose
not have the same safety characteristics as the SHARP
recommended replacement one, shown in the parts list in this
Service Manual, may create shock, fire or other hazards.
Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
information, always consult the current SHARP Service
Manual. A subscription to, or additional copies of, SHARP

Caution in the PDP W/B (No.4 to 15) adjustment:
Adjustment value is reflected without relation in input signal during adjustment to the actual PDP.
For example, when operate a adjustment value of [MNTR HIGH1] during PAL input, switch to the adjustment value operation of W/B table 1
while displaying PAL in the actual PDP.
This is temporary.
After adjustment, it becomes the W/B table 2 operation in the PAL input after restarted in the normal mode. It becomes an operation of the W/B
table 1 adjustment value after adjustment in the NTSC input.
As for the above example, table selection (No. 1 and 2) becomes the shipping setting.

Adjusting Point
VOFS (Offset voltage) adjustment
Method 1
1. Write down a adjustment value of VOFS ADJ in the factory mode.
2. Set this adjustment value to center (128).
3. Adjust VR2701 so that the voltage between K2701 (VOFS) and K2703 (SUS GND) becomes
45V.
4. Return it to the value that wrote down a adjustment value of V-OFFSET in step 1.
Method 2
1. Read the adjustment value of VOFS ADJ in the factory mode.
2. Adjust VR2701 so that the voltage between K2710 (VOFS) and K2703 (SUS GND) becomes
following voltage ± 0.5V.
If the VOFS Voltage adjustment is not performed properly, dots like blinking luminance points
appear. If deviated greatly from the right adjustment point, panel will light white.
VH (voltage for scan IC) Adjustment
Adjust so that the voltage between K2716 (VH) and K2720 (PSUS) becomes 103V ± 0.5V.
PSUS (=GNDH) is a floating GND and the electric potential is different from that of chassis
GND. Be sure not to short-circuit PSUS (=GNDH) and another GND, because that may
damage the unit.
The symptom is case of mis-adjustment
If the VH adjustment is not performed properly, dots like blinking luminance points appear. If
deviated greatly from the right adjustment point, panel will light white.
IC5V Adjustment
Adjust so that the voltage between K2707 (IC5V) and K2720 (PSUS) becomes 5.0V ± 0.1V.
VR2702 (IC5V)

Block diagram for Power supply section
Supplementary information
1. Power on/off switch for the large-signal system (SW102)
Function: Only the power for the small-signal system
(15V, 12V, 6.5V, 13.5V, and -9V) is on, and the
power for the large-signal system (VSUS, VADR) is
off.
Usage:Use when only an operational check for the small-
signal system is required.
Supplementary information:
When this switch is to be used, the wires of pin 5
(DIG, ADR, and PD) of the P2 connector of the
power-supply module should be disconnected to
prevent the PD circuit from operating. To turn the
power of the large-signal system off without using
this switch, operation from an external PC through
RS-232C commands "DRF" is basically required. In
this case, the above procedure is not required, as
the PD circuit is muted by software.
3. Temperature compensation of the VOFS voltage for
the drive system
Function: Control the power supply voltage mentioned
above according to temperature. (Temperature
compensation works so that the voltage is
lowered on the lower- temperature side, and is
raised on the higher-temperature side.)
Purpose: To improve the yield by compensating the
temperature characteristics of the panel.
Supplementary information:
For this model, temperature compensation is
perform-ed only for the VOFS voltage, and not for
the VSUS voltage, and it is controlled by
software.
4. When a fuse blows
• If a fuse blows, never turn the power on again only after
replacing the fuse. (In most cases, the fuse itself did not
have any problem. So as long as factors of overcurrent
have not been removed, chances of destruction increase
every time the power is turned on. In the worst case,
about a dozen parts may be destroyed.)
• Principally, the whole power-supply module must be
replaced.
5. Voltage adjustment of the panel drive
As this model employs the electronic VR system for the
VSUS and VOFS voltages, and as the voltage-adjustment
data are stored in the DIGITAL assembly, voltage
adjustment of the panel drive is not necessary when the
power-supply modules are changed. (For VADR, VH, and
VRN, adjustments with semifixed VR controls are
necessary.)
For this model, as the power-supply block has been
developed and designed by an outside vendor, at the point
you know which module is a cause of failure (through
diagnosis described elsewhere in this manual), change the
corresponding modules, and do not diagnose or repair the
module.
Similarly, the switches and the semifixed VRs inside the
power-supply module must not be adjusted without a
special reason.
2. 200V AC power-down switch (SW101)
Function: While 200V AC voltage is applied, operation of
the PD circuit is turned on and off (ON when the
switch is set to 100V AC, and OFF when the
switch is set to 200V AC).
Setting: For the PU model only, the switch is set to 100V,
and for other models, it is set to 200V.
Method of power supply ON in the large signal
system OFF state with RS-232C command
1 Confirm that this unit is the standby state.
2 Transmit RS-232C command "DRF."
3 Turn the power supply ON by remote control unit, side
key or command "PON."
∗ When turn the power supply OFF once, return to
setting of large signal system ON.
When turn the power supply ON in the large signal
system OFF, transmit "DRF" command each time.
