Note:

sRGB is a standard for ensuring correct exchange of colors between different devices(e. g. Digital cameras, monitor, printers, scanners, etc.)

Using a standard unified color space, sRGB will help represent pictures taken by an sRGB compatible device correctly on your sRGB enabled Philips monitor. In that way, the colors are calibrated and you can rely on the correctness of the colors shown on your screen.

Important with the use of sRGB is that the brightness and

VGA

contrast of your monitor is fixed to a predefined setting as

HDMI

well as the color gamut. Therefore it is important to select the sRGB setting in the monitor’s OSD.

Todoso,opentheOSDbypressingtheOKbuttononthe side of your monitor. More the down button to go to color and press OK again. Use the right button to go to sRGB. Then move the down button and press OK again to exit the OSD.

After this, please do not change the brightness or contrast setting of your monitor. If you change either of these, the monitor will exit the sRGB mode and go to a color temperature setting of 6500K.

Safety and Troubleshooting Information

190TW8 TV

Safety precautions and maintenance

WARNING: Use of controls, adjustments or procedures other than those specified in this documentation may result in exposure to shock, electrical hazards and/or mechanical hazards.

Read and follow these instructions when connecting and using your computer monitor:

a. To protect your display from possible damage, do not put

excessive pressure on the LCD panel. When moving your monitor, grasp the frame to lift; do not lift the monitor by placing your hand or fingers on the LCD panel.

b. Unplug the monitor if you are not going to use it for an

extensive period of time.

c. Unplug the monitor if you need to clean it with a slightly

damp cloth. The screen may be wiped with a dry cloth when the power is off. However, never use alcohol, solvents or ammonia-based liquids.

d. Consult a service technician if the monitor does not operate

normally when you have followed the instructions in this manual.

e. The casing cover should be opened only by qualified service

personnel.

f. Keep the monitor out of direct sunlight and away from stoves

or any other heat source.

g. Remove any object that could fall into the vents or prevent

proper cooling of the monitor’s electronics. h. Do not block the ventilation holes on the cabinet. i. Keep the monitor dry. To avoid electric shock, do not expose

it to rain or excessive moisture. j. When positioning the monitor, make sure the power plug and

outlet are easily accessible. k. If turning off the monitor by detaching the power cable or DC

power cord, wait for 6 seconds before attaching the power

cable or DC power cord for normal operation. l. To avoid the risk of shock or permanent damage to the set,

do not expose the monitor to rain or excessive moisture. m. IMPORTANT: Always activate a screen saver program during

your application. If a still image in high contrast remains on

the screen for an extended period of time, it may leave an

'after-image' or 'ghost image' on front of the screen. This is a

well-known phenomenon that is caused by the shortcomings

inherent in LCD technology. In most cases, the afterimage

will disappear gradually over a period of time after the power

has been switched off. Be aware, that the afterimage

symptom cannot be repaired and is not covered under

warranty. o. Warning for lifting monitor - Do not use the area underneath

the logo cover to grip or lift the monitor. Placing weight on the

logo cover can cause it to break away from the body and

cause the monitor to fall. When lifting the monitor, place one

hand under the monitor's frame.

For further assistance, refer to the Consumer Information Centers list and contact your local Philips distributor.

Adjust the contrast and brightness on On-Screen Display.(The backlight of the LCD monitor has a fixed life span. When the screen becomes dark or begins to flicked, please contact your sales representative).

If an image remains on the screen for an extended period of time, it may be imprinted in the screen and leave an after-image. This usually disappears after a few hours.

This is characteristic of liquid crystal and is not caused by a malfunction or deterioration of the liquid crystal. The after-image will disappear after aperoidoftime.

The remaining dots are normal characteristic of the liquid crystal used in today’s technology.

Definition of Pixel Defects

This section explains the different types of pixel defects and defines acceptable defect levels of each type. In order to quality for repair or replacement under warranty, the number of pixel defects on a TFT LCD panel must exceed these acceptable levels.

Bright Dot Defects

Bright dot defects appear as pixels or sub pixels that are always lit or 'on'. That is, a bright dot is a sub-pixel that stands out on the screen when the monitor displays a dark pattern. There are the types of bright dot defects:

One lit red, green or blue sub pixel

Two adjacent lit sub pixels:

-Red+Blue=Purple

- Red + Green = Yellow

- Green + Blue = Cyan (Light Blue)

Three adjacent lit sub pixels (one white pixel)

1. Definition of Pixels and Sub-pixels

A pixel, or picture element, is composed of three sub pixels in the primary colors of red, green and blue. Many pixels together form an image. When all sub pixels of a pixel are lit, the three colored sub pixels together appear as a single white pixel. When all are dark, the three colored sub pixels together appear as a single black pixel. Other combinations of lit and dark sub pixels appear as single pixels of other colors.

subpixel subpixel subpixel

RGB

Pixel

A red or blue bright dot must be more than 50 percent brighter than neighboring dots while a green bright dot is 30 percent brighter than neighboring dots.

Black Dot Defects

Black dot defects appear as pixels or sub pixels that are always dark or 'off'. That is, a dark dot is a sub-pixel that stands out on the screen when the monitor displays a light pattern. These are the types of black dot defects:

One dark sub pixel

Two or three adjacent dark sub pixels

2. Types of Pixel Defects

Pixel and sub pixel defects appear on the screen in different ways. There are two categories of pixel defects and several types of sub pixel defects within each category.

Definition of pixel defects

3. Proximity of Pixel Defects

Because pixel and sub pixels defects of the same type that are near to one another may be more noticeable, Philips also specifies tolerances for the proximity of pixel defects. Perfect Panel - ISO 13406-2 Class II compliant do-defectfree-display.

Safety Instruction, Warnings and Notes

Safety instruction, warnings and notes

index of this chapter: 1 Safety Instructions 2 Warnings 3 Notes

1 Safety Instructions

Safety regulations require that during a repair:

a. Connect the set to the AC Power via an isolation transformer

(> 800 VA).

b. Replace safety components, indicated by the symbol ,

only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard.

Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points:

a. Route the wire trees correctly and fix them with the mounted

cable clamps.

b. Check the insulation of the AC Power lead for external

damage.

c. Check the strain relief of the AC Power cord for proper

function.

d. Check the electrical DC resistance between the AC Power

plug and the secondary side (only for sets which have a AC Power isolated power supply):

* Unplug the AC Power cord and connect a wire between the

two pins of the AC Power plug.

* Set the AC Power switch to the "on" position (keep the AC

Power cord unplugged!).

* Measure the resistance value between the pins of the AC

Power plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be between 4.5 Mohm and 12 Mohm.

* Switch "off" the set, and remove the wire between the two

Pins of the AC Power plug.

e. Check the cabinet for defects, to avoid touching of any inner

parts by the customer.

3.2 Schematic Notes

All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates

2.2 Kohm).

Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ohm).

All capacitor values are given in micro-farads ( X10 ), nano-farads (n= X10 ), or pico-farads (p= X10 ).

Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF).

An "asterisk" (*) indicates component usage varies. Refer to the diversity tables for the correct values.

The correct component values are listed in the Electrical Replacement Parts List. Therefore, always check this list when there is any doubt.

3.3 Lead Free Solder

Philips CE is going to produce lead-free sets (PBF) from

1.1.2005 onwards. Lead-free sets will be indicated by the PHILIPS-lead-free logo on the Printed Wiring Boards (PWB):

This sign normally has a diameter of 6 mm, but if there is less space on a board also 3 mm is possible.

-9 -12

-6

2 Warnings

a. All ICs and many other semiconductors are susceptible to

electrostatic discharges (ESD ). Careless handling during repair can reduce life drastically. Make sure that, during

repair,

you are connected with the same potential as the mass of the set by a wristband with resistance. Keep components and

tools also at this same potential. b. Be careful during measurements in the high voltage section. c. Never replace modules or other components while the unit

is switched "on". d. When you align the set, use plastic rather than metal tools.

This will prevent any short circuits and the danger of a circuit

becoming unstable.

3 Notes

3.1 General

Measure the voltages and waveforms with regard to the chassis ground or hot ground, depending on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative.

The semiconductors indicated in the circuit diagram and in the parts lists, are interchangeable per position with the semiconductors in the unit, irrespective of the type indication on

In case of doubt wether the board is lead-free or not (or with mixed technologies), you can use the following method:

* Always use the highest temperature to solder, when using

SAC305 (see also instructions below).

* De-solder thoroughly (clean solder joints to avoid mix of

two alloys).

Caution

profile, which is coupled to the 12NC. For an overview of these profiles, visit the website You will find this and more technical information within the "Magazine", chapter "Workshop information". For additional questions please contact your local repair desk.

Due to lead-free technology some rules have to be respected by the workshop during a repair:

Use only lead-free soldering tin Philips SAC305 with order code 0622 149 00106. If lead-free solder paste is required, please contact the manufacturer of your soldering equipment. In general, use of solder paste within workshops should be avoided because paste is not easy to store and to handle.

Use only adequate solder tools applicable for lead-free soldering tin. The solder tool must be able

- To reach at least a solder-tip temperature of 400 degree C.

- To stabilise the adjusted temperature at the solder-tip.

- To exchange solder-tips for different applications.

: For BGA-ICs, you must use the correct temperature
