SECTION 1 
PRECAUTION 


1.1 SAFETY PRECAUTIONS 

(1) The design of this product contains special hardware, 
many circuits and components specially for safety 
purposes. For continued protection, no changes should 
be made to the original design unless authorized in writing 
by the manufacturer. Replacement parts must be identical 
to those used in the original circuits. Service should be 
performed by qualified personnel only. 

(2) Alterations of the design or circuitry of the products should 
not be made. Any design alterations or additions will void 
the manufacturer's warranty and will further relieve the 
manufacturer of responsibility for personal injury or 
property damage resulting therefrom. 

(3) Many electrical and mechanical parts in the products have 
special safety-related characteristics. These 
characteristics are often not evident from visual inspection 
nor can the protection afforded by them necessarily be 
obtained by using replacement components rated for 
higher voltage, wattage, etc. Replacement parts which 
have these special safety characteristics are identified in 
the parts list of Service manual. Electrical components 
having such features are identified by shading on the 
schematics and by (A) on the parts list in Service 
manual. The use of a substitute replacement which does 
not have the same safety characteristics as the 
recommended replacement part shown in the parts list 
of Service manual may cause shock, fire, or other hazards. 

(4) Don't short between the LIVE side ground and ISOLATED 
(NEUTRAL) side ground or EARTH side ground when 
repairing. 

Some model's power circuit is partly different in the GND. 
The difference of the GND is shown by the LIVE : ( Ai ) side 
GND, the ISOLATED (NEUTRAL) : ( i ) side GND and 
EARTH : ( @ ) side GND. Don't short between the LIVE 
side GND and ISOLATED (NEUTRAL) side GND or EARTH 
side GND and never measure the LIVE side GND and 
ISOLATED (NEUTRAL) side GND or EARTH side GND at 
the same time with a measuring apparatus (oscilloscope 
etc.). 

If above note will not be kept, a fuse or any parts will be 
broken. 

(5) If any repair has been made to the chassis, it is 
recommended that the B1 setting should be checked or 
adjusted (See ADJUSTMENT OF B1 POWER SUPPLY). 

(6) The high voltage applied to the picture tube must conform 
with that specified in Service manual. Excessive high 
voltage can cause an increase in X-Ray emission, arcing 
and possible component damage, therefore operation 
under excessive high voltage conditions should be kept 
to a minimum, or should be prevented. If severe arcing 
occurs, remove the AC power immediately and determine 
the cause by visual inspection (incorrect installation, 
cracked or melted high voltage harness, poor soldering, 
etc.). To maintain the proper minimum level of soft X-Ray 
emission, components in the high voltage circuitry 
including the picture tube must be the exact replacements 
or alternatives approved by the manufacturer of the 
complete product. 

(7) Do not check high voltage by drawing an arc. Use a high 
voltage meter or a high voltage probe with a VTVM. 
Discharge the picture tube before attempting meter 
connection, by connecting a clip lead to the ground frame 
and connecting the other end of the lead through a 10kQ 
2W resistor to the anode button. 


(8) When service is required, observe the original lead dress. 
Extra precaution should be given to assure correct lead 
dress in the high voltage circuit area. Where a short circuit 
has occurred, those components that indicate evidence 
of overheating should be replaced. Always use the 
manufacturer's replacement components. 

(9) Isolation Check 

(Safety for Electrical Shock Hazard) 

After re-assembling the product, always perform an 
isolation check on the exposed metal parts of the cabinet 
(antenna terminals, video/audio input and output 
terminals, Control knobs, metal cabinet, screw heads, 
earphone jack, control shafts, etc.) to be sure the product 
is safe to operate without danger of electrical shock. 

a) Dielectric Strength Test 

The isolation between the AC primary circuit and all metal 
parts exposed to the user, particularly any exposed metal 
part having a return path to the chassis should withstand 
a voltage of 3000V AC (r.m.s.) for a period of one second. 
(. . . . Withstand a voltage of 1100V AC (r.m.s.) to an 
appliance rated up to 120V, and 3000V AC (r.m.s.) to an 
appliance rated 200V or more, fora period of one second.) 
This method of test requires a test equipment not generally 
found in the service trade. 

b) Leakage Current Check 

Plug the AC line cord directly into the AC outlet (do not use 
a line isolation transformer during this check.). Using a 
"Leakage Current Tester", measure the leakage current 
from each exposed metal part of the cabinet, particularly 
any exposed metal part having a return path to the chassis, 
to a known good earth ground (water pipe, etc.). Any 
leakage current must not exceed 0.5mAAC (r.m.s.). 
However, in tropical area, this must not exceed 0.2mAAC 
(r.m.s.). 

Alternate Check Method 

Plug the AC line cord directly into the AC outlet (do not 
use a line isolation transformer during this check.). 
Use an AC voltmeter having 1000 ohms per volt or 
more sensitivity in the following manner. Connect a 
1500L2 10W resistor paralleled by a 0.15pF AC-type 
capacitor between an exposed metal part and a known 
good earth ground (water pipe, etc.). Measure the AC 
voltage across the resistor with the AC voltmeter. Move 
the resistor connection to each exposed metal part, 
particularly any exposed metal part having a return path 
to the chassis, and measure the AC voltage across 
the resistor. Now, reverse the plug in the AC outlet and 
repeat each measurement. Any voltage measured 
must not exceed 0.75V AC (r.m.s.). This corresponds 
to 0.5mAAC (r.m.s.). 

However, in tropical area, this must not exceed 0.3V AC 
(r.m.s.). This corresponds to 0.2mAAC (r.m.s.).

1.3 PRECAUTIONS 


(1) Depending on the around temperature, the brightness leaning occurs. Be careful of the environment in the product 
installation place and so on sufficiently. 

(2) Don't hinder radiation from the back, the heaven and the side. Please refer to the next page that explains about the 
condition of the installation. 

The inside becomes hot if hindering radiation and there is fear, which the inner circuit damages. 

(3) Install in the place with good ventilation. Use in the condition that around temperature is in the 0~35°C range. 

(4) Avoid preservation and use at the high temperature or high humidity place. If you behave like this, leaning sometimes 
happens in the screen when the set actives. 

(5) Depending on the condition and the environment of display, the slight fleck of the light and leaning of the screen and so on 
is sometimes conspicuous. This is the characteristic which is peculiar to liquid crystal display. It is not set trouble. 

(6) This monitor has cool cathode pipe as the backlight. The time change and the use time sometimes change brightness 
and condition of display. 


1.4 THEATTENTION IN TRANSPORTATION

SECTION 2 

SPECIFIC SERVICE INSTRUCTIONS 

2.1 DESCRIPTION ABOUT LIQUID CRYSTAL PANEL 

2.2.1 STRUCTURE OF LIGUID CRYSTAL PANEL 

The Liquid Crystal Panel of this model is TFT Panel. The Print circuit board that consist of TFT array and the print circuit board 
adopted stripe shaped image element alignment are used. These two boards are mixed. The Liquid crystal is enclosed between 
two boards. 

2.1 .2 LONG RANGE AFTERIMAGE OF LIQUID CRYSTAL 

The small amount of ion material has mixed a liquid crystal panel with the liquid crystal material in the manufacturing process. 
If ion material is piled up partially among the poles when the voltage is impressed among the poles, the brightness difference 
occurs and becomes a long-range afterimage If same picture is reflected for long time, such a long-range afterimage occurs. If 
the long-range afterimage occurs, we recommend that you reflect the single color image and so on to restore. 

2.1.3 THE DISPLAY REPLYING SPEED OF LIQUID CRYSTAL 

Because the speed to display of Liquid crystal panel is slower than the speed of the CRT monitor, some of the moving picture 
cannot overtake to the speed to display and the image looks flowing is sometimes displayed. This is not trouble, but efficiency 
of Liquid Crystal. 

2.1 .4 THE EYESIGHT CORNER OF LIQUID CRYSTAL 

The liquid crystal panel has the wide eyesight corner for which it is difficult to reverse brightness. The tint changes depending on 
the direction to see a screen. This is not trouble, but efficiency of Liquid Crystal. 

2.1.5 THE PICTURE ELEMENT FAULT OF LIQUID CRYSTAL 

The liquid crystal panel is composed of precise technique but all devices don't always work right. 


2.2 ATTENTION ITEMS WHEN REPLACING PARTS 

2.2.1 ATTENTION TO EXCHANGE THE LIQUID CRYSTAL PANEL 

(1) The stillness electricity sometimes makes damage a liquid crystal panel. In liquid crystal panel exchange, do a measure 
of the stillness electricity such as the earth band. 

(2) A liquid crystal panel and back-light are made from glass. If you gain an impact to these materials, there is fear to damage. 
So in case of treatment, be careful sufficiently. 

(3) Fix with the screw after confirming that there is not a float to chassis base when exchanging liquid crystal panel. 

After that reflect all the black signals and confirm that brightness leaning doesn't occur near the screw fixation part. 
When brightness leaning occurs, slacken a screw in the neighborhood until the brightness leaning is running-out. 

(4) Fix the torque that installs a screw below 0.294Nm. 

If you install at any more torque, the liquid crystal panel is transformed and sometimes damages. 

(5) If you pull out or insert each connector when power is ON, it causes the trouble. 

So pull out or insert each connector in the condition to have pulled out a power supply plug. 

2.2.2 ATTENTION WHEN EXCHANGING THE BACK-LIGHT 

(1) The back-light is the glass which used cool cathode pipe. In treatment and exchange, pay attention to the following point. 

(2) Leave the set for a while in the condition that the power is off. Behave the exchanging after lamp's getting cold sufficiently. 

(3) Adhering the garbage or dust to the luminous part causes brightness leaning Don't touch a part except the lamp folder. 

(4) The lamp part is fear to break if extra power is gained by the part of the neighborhood of the liquid crystal panel and so on. 
Handle the lamp folder and pull out slowly. 

(5) In installation, insert the lump slowly until the nail of the lamp fixation hangs. 

(6) Dispose of the exchanged background light according to the local code. 

2.2.3 ATTENTION WHEN EXCHANGING THE MAIN PWB 

To show the original efficiency of the MAIN PWB, pull out a heat think from the previous MAIN PWB and install it in the new PWB 
surely. 

2.2.4 ATTENTION WHEN EXCHANGING THE FUSE 

When exchanging the fuse, please use specified parts. After fuse exchange, confirm that insulater is set to the shield and 
insulate surely.

Basic Connection Example 


Notes: 


Q Before connecting your system, make sure that all devices are turned off. 

□ The illustration shows some examples of different connections. Terminal connections may differ depending on 
the devices. Be sure to refer to the manuals provided with the devices. 

□ Each pair of input (IN) and output (OUT) terminals are bridge-connected 

Q If you’re not connecting any equipment to a bridged output (OUT) terminal, be sure not to connect any other 
cables to the bridged output (OUT) terminal as this will cause the terminating resistance switch to open (auto 
terminate function). 

Q When making a bridge connection, connect the input (IN) and output (OUT) terminals on the monitor to separate 
video components. (For example, if both terminals are connected to the same VCR, resonance may occur except 
during playback. This is caused by the same video signal “looping” between the VCRs, and is not a malfunction.) 


Q The ASPECT or INPUT A/B settings can be controlled via the ASPECT or INPUT jack in the REMOTE terminal. 
0 When using REMOTE terminal, set REMOTE function ON . See “SYSTEM SETTING menu “ on 
page 11.

Troubleshooting 

Solutions to common problems related to your monitor are described here. If none of the solutions presented here 
solove the problem, unplug the monitor and consult a JVC-authorised dealer or service centre for assistance. 

A. My monitor doesn’t work. 

■ Check that the power cable is securely plugged into the monitor. 

■ Check that the monitor is turned on. 

■ Turn the monitor off and pull the plug out, then put the plug in again and turn the monitor on. 

B. My monitor shows no colors, wrong color, or dark pictures. 

■ Check that the color system is selected correctly. See “SYSTEM SETTING menu” on page 1 1 . 

■ Check the BACK LIGHT and PICTURE ADJ. settings. See “BACK LIGHT menu” and “PICTURE ADJ. 
menu” on page 9. 

■ In the PC mode, check the CONTRAST setting. See “CONTRAST menu” on page 1 1 . 

C. Dark stripes appear at the top and bottom of the screen, picture vertically squeezed. 

■ Set the ASPECT setting to “4:3”. See “PICTURE ADJ. menu” on page 9. 

D. The message “No Sync” appears . 

This message appears when there is no video signal. After few seconds, the monitor goes into the reduced 
power mode. 

■ Check the connection. 

■ Select the required video signal input. 

■ Connect the video signal cable firmly. 

■ Check that your graphic card outputs the analog RGB signal. 

E. The message “Signal Out of Range” appears on my monitor. 

This message appears when the input signal is beyond the monitor capability. 

Set your PC to a supported video mode; preferably 1024 x 768 at 60 Hz. 

F. The image is very unstable in the PC mode. 

■ Set your PC to a supported video mode; preferably 1024 x 768 at 60 Hz. 

■ Restore the original factory settings by “All reset”. See “SYSTEM SETTING menu” on page 11. 

■ Do the “AUTO SET UP”. See “AUTO SET UP” on page 13. 

Note: Even if your PC’s setting is out of the range of video modes that are supported by your LCD monitor, it 
may still be displayed with reduced quality. This provides you with an opportunity to change your PC’s 
setting to a correct one. 


The following are not malfunctions: 

Q The monitor emits a strange sound when the room temperature changes suddenly. This is only a problem if an 
abnormality appears on the screen as well. 

□ When a still image as been displayed fora long period, a faint residual image may remain on the screen for a short 
time after the power has been turned off or when another image is displayed. The image will eventually 
disappear. 

Q When you see the monitor from the side, the color or brightness look different. 

Q The LCD panel is made with high-precision technology and has more than 99.99% effective pixels. 

Fewer than 0.01% of pixels may be chipped or always lit.
