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.)

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

Timing Adjustment of X and Y DRIVE Assys Control Signal

Purpose

• Pulse module loads in DRIVE Assy as one of heat measures of DRIVE Assy. Adjust the drive timing of the pulse module
driving parallel with VR.

• Pulse module has each peculiar delay time. Readjustment is necessary when replaced the pulse module in the X and
Y DRIVE Assys.

Adjustment Method

CR delay circuit is each inserted on signal path of four control signals (SUS-U, SUS-B, SUS-D, SUS-G) driving
the pulse module.
Quantity of delay can adjust pulse module of one side with VR.
Adjust VR while measuring a waveform of the pulse module, and match a timing.

• Perform adjustment of waveform with a black mask screen.

• It is easy to adjust when turned field AB offset to OFF (RS-232C

command: OCN) in adjustment.

Note:

• Sampling rate of oscilloscope sets it more than 500MS/s in order
to perform ns order adjustment.

• Collecting calibration of probe before adjustment by all means.

• Connect GND of probe measuring waveform to SUSGND terminal

by all means.

• Precise waveform is not displayed, and an adjustment gap may
occur that does not collect GND properly.

When took waveform be each drive Assy unit, measure it at the
fourth sustain pulse from the back except for a large width sustain
pulse.
Therefore, when measured both waveform of the X and Y drives
together, it becomes the sustain pulse of 8 and 9 pulses from the
back.

Confirm it to waveform of CH1 / CH2 of the part which enclosed in
the following circle whether there is not a large gap.
(A gap of the quantity that shifts 20nS and adjusted remains.)

When adjust in the power supply ON state, change so that the
quantity of gap that adjusted by temperature-rise of the pulse
module becomes small.
Therefore, perform high power OFF (RS-232C command: DRF)
except measurement time of waveform when adjusts, and
adjustment error by temperature-rise does not occur.

SUS-B Ground Timing Adjustment

It is necessary to readjust this adjustment when replaced the X or Y DRIVE Assy and the pulse module.

Measurement point and method

Measurement point of waveform of X and Y DRIVE Assy in timing adjustment is test pin of SUSOUT of the pulse module of
bottom of the main unit.
X DRIVE Assy : K3106 Y DRIVE Assy : K2203
Measurement screen : White mask

The measurement is easy to perform when turns field AB alternation to OFF. (RS-232C command: OCN)
Measure a sustain pulse of the fourth pulse (X DRIVE) and the fifth pulse (Y DRIVE) from the back of the fourth FS, and

adjust. In the start section of this sustain pulse, waveform has inflection point with the timing when SUS-B becomes ON.
Adjust so that the voltage of this inflection point is the nearest to 150V and do not become less than 150V.

Adjustment parameter

X DRIVE: XSUSB (RS-232C command : XSB)
Y DRIVE: YSUSB (RS-232C command : YSB)

Note:

• Connect GND of probe measuring waveform to SUSGND terminal by all means.

• Precise waveform is not displayed, and an adjustment gap may occur that does not collect GND properly.
