alsobe replaced onlywithspecified replacements.
Examples:RFconverters,tunerunits,antenna
selection switches,RFcables,noise-blocking
capacitors,noise-blocking filters,etc.
2.Usespecified internalWiring.Noteespecially:
1)Wirescovered withPVCtubing
2)Doubleinsulated wires
3)High voltage leads
3.Usespecified insulating materialsforhazardous
liveparts.Noteespecially:
1)Insulating Tape
2)PVCtubing

WARNING:
Beforeservicing thisTVreceiver,read the X-RAY
RADIATIONPRECAUTION,SAFETYINSTRUCTION
and PRODUCTSAFETYNOTICE.
X-RAYRADIATIONPRECAUTION
1.Excessivelyhigh can producepotentiallyhazardous
X-RAY RADIATION.Toavoidsuchhazards,the high
voltage mustnotexceed the specified limit. The
normalvalue ofthe high voltage ofthisTVreceiver
is27 KV atzerobean current(minimumbrightness).
The high voltage mustnotexceed 30 KV underany
circumstances.Eachtimewhen areceiverrequires
servicing,the high voltage shouldbe checked.The
reading ofthe high voltage isrecommended tobe
recorded asapartofthe servicerecord,It is
importanttousean accurateand reliablehigh
voltage meter.
2.The onlysourceofX-RAY RADIATIONinthisTV
receiveristhe picturetube.Forcontinued X-RAY
RADIATIONprotection,the replacementtube mustbe
exactlythe sametype asspecified inthe partslist.
3.SomepartsinthisTVreceiverhavespecialsafety
related characteristics forX-RADIATIONprotection.
Forcontinued safety,the partsreplacementshould
be undertaken onlyafterreferring the PRODUCT
SAFETYNOTICE.
SAFETYINSTRUCTION
The serviceshouldnotbe attempted byanyone
unfamiliarwiththe necessaryinstructionson thisTV
receiver.The following arethe necessaryinstructions
tobe observed beforeservicing.
1.Anisolation transformershouldbe connected inthe
powerline between the receiverand the ACline
when aserviceisperformed on the primaryofthe
convertertransformerofthe set.
2.Complywithall caution and safetyrelated provided
on the back ofthe cabinet, inside the cabinet, on the
chassisorpicturetube.
3.Toavoidashock hazard,always discharge the
picturetube'sanode tothe chassisground before
removing the anode cap.

5.When replacing aMAINPCBinthe cabinet, always
be certainthatall protectiveareinstalled properly
suchascontrolknobs,adjustmentcoversorshields,

6.When servicing isrequired,observethe originallead
dressing.Extraprecaution shouldbe given toassure
correctlead dressing inthe high voltage area.
7.Keep wiresawayfromhigh voltage orhigh tempera
turecomponents.
8.Beforereturning the settothe customer,always
perform an ACleakage currentcheck on the exposed
metallicpartsofthe cabinet, suchasantennas,
terminals,screwheads,metaloverlay,controlshafts,
etc., tobe surethe setissafetooperatewithout
dangerofelectricalshock.Plug the ACline cord
directlytothe ACoutlet(do notusealine isolation

having 5Kohmsvoltsensitivityormoreinthe
following manner.
Connecta1.5Kohm10 watt resistorparalleled bya
0.15µFACtype capacitor,between agood earth
ground (waterpipe,conductoretc.,)and the exposed
metallicparts,one atatime.
Measurethe ACvoltage across the combination of
the 1.5Kohmresistorand 0.15 uFcapacitor.Reverse
the ACplug atthe ACoutletand repeatthe AC
voltage measurementsforeachexposed metallic

The measured voltage mustnotexceed 0.3VRMS.
Thiscorrespondsto0.5mAAC.Anyvalue exceeding
thislimitconstitutesapotentialshock hazardand
mustbe corrected immediately.
The resistancemeasurementshouldbe done
between accessibleexposed metalpartsand power

Test Condition
All tests shall be performed under the following conditions unless otherwise specified
1 Picture Modulation 87.5%
2 Sound Modulation
27KHz Dev. For DK/I/BG
15KHz Dev. For M/N
3 Picture to Sound Ratio 10dB
4 Sound Artificial Load
Resistor
8 ohm
5 Video signal Stair and Special
6 Audio signal 1KHz sine wave 0.5Vrms
7 Other conditions:
A. Switch LCD-TV on and let it warm up for more than 30 minutes.
Viewing distance: 3H (H: Panel High) in front of LCD, about 2M.
Ambient light: ≤0.1 cd/ m2
B. Brightness, Contrast, Saturation, Tint, sharpness set at normal.
C. Connect RMS volt meter to speaker terminals and adjust the LCD volume to get 500mW RMS
power at each terminals.
D. With image sticking protection of LCD module. The luminance will descend by time on a same
still screen and rapidly go down in 5 minutes, when measuring the color tracking and luminance
of a same still screen, be sure to accomplish the measurement in one minute to ensure its
accuracy.
E. Due to the structure of LCD module. The extra-high-bright same screen should not hold over 5
minutes for fear of branding on the panel.
F. RF test point: Video output.
8 Note:
*(1) Now this project cannot fit the limited spec. the typical audio input level is 1.0 Vrms,
*(2) The audio out level is controlled by the volume level, the range is from 0 to 0.5Vrms.
