1. Precautions and Safety Notices

1. SAFETY PRECAUTIONS

This monitor is manufactured and tested on a ground principle that a user’s safety comes first.

However, improper used or installation may cause damage to the monitor as well as to the user.

WARNINGS:

 This monitor should be operated only at the correct power sources indicated on the label on

the rear of the monitor. If you’re unsure of the power supply in you residence, consult your

local dealer or Power Company.

 Use only the special power adapter that comes with this monitor for power input.
 Do not try to repair the monitor by yourself, as it contains no user-serviceable parts. Only the

qualified technician can repair it.

 Do not remove the monitor cabinet. There are high-voltage parts inside that may cause

electric shock to human bodies.

 Stop using the monitor if the cabinet is damaged. Have it checked by a service technician.
 Put your monitor only in a lean, cool, dry environment. If it gets wet, unplug the power cable

immediately and consult your closed dealer.

 Always unplug the monitor before cleaning it. Clean the cabinet with a clean, dry cloth. Apply

non-ammonia based cleaner onto the cloth, not directly onto the glass screen.

 Do not place heavy objects on the monitor or power cord.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in this chassis have special safety visual inspections and

the protection afforded by them cannot necessarily be obtained by using replacement

components rated for higher voltage, wattage, etc. Before replacing any of these components

read the parts list in this manual carefully. The use of substitute replacement parts, which do not

have the same safety characteristics as specified in the parts list, may create shock, fire, or other

hazards.

3. SERVICE NOTES

 When replacing parts or circuit boards, clamp the lead wires around terminals before

soldering.

 Keep wires away from high voltage, high temperature components and sharp edges.
 Keep wires in their original position so as to reduce interference.
 Adjustment of this product please refers to the user’ manual.

4. Circuit Description

1. Switching Mode Power Supply

1.1 AC Current Input Circuit

P801 is a connector for connecting AC Power. F801 is a fuse to protect all the circuit. AC

input voltage is from 90V to 264V. R801 and R802 joined between two inputting main circuit

to prevent man from shock. L801 is used to clear up low frequency wave. C801 and C802

are used to discharge the waves that L801 produced. High frequency waves are damped by

C801 and C802. D801 is a rectifier which composed of 4 build-in diodes, it inverts AC to

DC.

1.2 High Voltage to Low Voltage Control Circuit

C804 is used to smooth the waveform from rectifier. IC802 is a highly integrated PWM

controller, which control the power MOSFET Q804. When rectified DC high voltage is

applied to the DRAIN pin during start-up, the MOSFET is off initially, and the capacitor C807

be charged through D802,R803 and the HV pin of IC802,when the voltage VCC reaches

the threshold level 12.8V,IC 802 start up and create a PWM signal to control the power

MOSFET, then energy is transferred to secondary terminal through the transformer

T801,the auxiliary voltage 12V and the output voltage 5V/14V be created ,the auxiliary

voltage supply a continue current to IC802,the level of output voltage is feedback to FB pin

of IC802 through R823,R824,R822,IC803 and IC803 witch control the duty of the PWM

signal, then all the convert circuit go to a stable operating station.

R805 R806 R835 ZD801 ZD806 and Q806 formed a under input voltage protection

circuit , only the input AC voltage over the threshold level approximately 63V AC, the switch

Q801 can be on and then the auxiliary voltage can supply a continue current to

IC802;R808,R807,R836,R812,R815,R836,D806 and Q805 formed a over line current

protection circuit witch limited the input power under approximately 63W. ZD805 will be on

when the output voltage is too high or the feedback circuit open, the current will drive

transistor Q805 open through R830,D814 and made IC802 off the PWM waveform; the high

voltage spike created by transformer’s primary winding during the transistor turn off will be

consumed through D804 R813 R814 and C806, This will prevent MOSFET which built-in

IC802 from being damaged under large current impulse and voltage spike.

1.3 DC_5V and DC_14V Output Circuit

For DC 5V, D808 is used to rectify the inducted current. R817 and C815 are used to store

energy when current is reversed. The parts including C824,C818,C822 and L803 are used

to smooth the current waves.

For DC 14V, D807 is used to rectify the inducted current. R816 and C814 are used to

store energy when current is reversed. The parts including C816,C817,C819 and L802 are

used to smooth the current waves.

1.4 Feedback and OVP Protect Circuit

Pin R of IC803 is supplied 2.5V stable voltage. It is connected to 5V and 14V output through

30

ViewSonic Corporation Confidential - Do Not Copy VA2016w-2

R823, R824 and R822. R823 R824 and R822 are output sampling resistor. When the

sampling voltage more than 2.5V or less than 2.5V, feedback current of IC802 will change,

this can change the voltage from transformer T801.

For output OVP, ZD803,ZD804 and ZD805 are zener diode, when the voltage add to the

zener up to their’s rating voltage 5.6V, 3.9V or 20V, the zener’s leakage current cause R828

voltage become up to 0.7V, Q803 is triggered and OVP starts. The collector current of Q803

is used to make build-in diode light. FB Current of IC802 will be changed; it can change the

output voltage from T801.

2. Inverter Circuit

2.1 Low voltage to high voltage circuit

14VDC provides the power for IC501; the control signals Brightness and ON/OFF come

from I/F board. ON/OFF signal connect to pin8 of IC501 and makes IC501 enable. Brightness

signal connect to pin7 of IC501 and regulates the panel brightness, R524, R529, C505 make up

a network of delaying time circuit and R528, R523, R524 make up a divided voltage network,

C504 is used to dump noise. The operation frequency is determined by the external Resistor

R522 and capacitor C529 connected to pin5 of IC501. BURST MODE regulated dimming

frequency is determined by the external resistor R527 and capacitor C506 connected to pin6 of

IC501. C502 is used for soft start and compensation, C502, C528 are used for dump noise.

The output drives, include NDR4, NDRV2, PDRV3, PDRV1 (pins1, 3, 15, 16 respectively)

output square pulses to drive MOSFET U501, U502, and each of U501, U502 is consist of a N

channel MOSFET and a P channel MOSFET. U501 and U502 work as full-bridge topology, it is

high efficient, zero voltage switching.

During start up, VSEN (pin9) senses the voltage at the transformer secondary. When VSEN

reaches 3.0V, the output voltage is regulated. If no current is sensed approximately 1.5 seconds

IC501 shunt off.

The current flowing through CCFL is sensed and regulated through sense resistor R509,

R511. The feedback voltage through R506, R507, C508 connected to Pin11 (ISEN), then

compared with a reference voltage (1.5V) via a current amplifier, resulting in PWM drive outputs

to full-bridge switches.

2.2 Protection circuit

Over Voltage Protection: R501and R502 are connected in high voltage output connector, the

divided AC voltage is inverted DC voltage through D508, R505 and C507are used to rectify wave

& dump noise. Then the voltage signal reaches Pin9 VSEN of IC501, when the voltage changes,

build-in PWM of IC501 will adjust output voltage.

Open Lamp Protection: In normal operation, the resistors R510, R511, R512, R509 are

sensed a high level AC voltage, the AC signal IS1 invert DC voltage through D509, R515, C533,

and the high level DC voltage reaches the gate pin of Q502, similarly, the gate pin of Q503, Q504,

31

ViewSonic Corporation Confidential - Do Not Copy VA2016w-2

Q505 has high level DC voltage. So the gate pin of Q501 has a low level voltage, and the IC501

is normal operation. Once one of signal OP1,OP2,OP3,OP4 is low, the voltages of Q501 gate

pin is high level, and make the voltage of ISEN low level, the IC501 will be shunt down.

6.1. Common Acknowledge

z If you change the interface board, be sure that the U103, U105, U106 and U108 these three

components also changed to the new I/F board because there was program inside. If not,
please re-write EDID and upload firmware into U106 via VGA Cable.

z If you adjust clock and phase, please do it at the condition of Windows shut down pattern.
z If you confirm the R.G.B. color is normal or not, please do it under 16-grey scalar pattern.
z This LCM is analog interface. So if the entire screen is an abnormal color that means the

problem happen in the analog circuit part, if only some scale appears abnormal color that
stand the problem happen in the digital circuit part.

z If you check the H/V position, please use the crosshatch pattern.
z This LCM support more than 30 timing modes, if the input timing mode is out of specification,

the picture may appears abnormally.

z If brightness uneven, repairs Inverter circuit or change a new panel.
z If you find the vertical line or horizontal line lost on the screen, please change panel.
z If you find the speaker don’t working, please don’t plug in audio cable, unless change new

speaker.
