3.4 Abbreviation List

3.1 Safety Instructions

Safety regulations require the following during a repair:

• Connect the set to the Mains/AC Power via an isolation transformer (> 800 VA).

• Replace safety components, indicated by the symbol h, 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:

• Route the wire trees correctly and fix them with the mounted cable clamps.

• Check the insulation of the Mains/AC Power lead for external damage.

• Check the strain relief of the Mains/AC Power cord for proper function.

• Check the electrical DC resistance between the Mains/AC Power plug and the secondary side (only for sets that have a Mains/AC Power isolated power supply):

1. Unplug the Mains/AC Power cord and connect a wire

between the two pins of the Mains/AC Power plug.

2. Set the Mains/AC Power switch to the “on” position

(keep the Mains/AC Power cord unplugged!).

3. Measure the resistance value between the pins of the

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

4. Switch “off” the set, and remove the wire between the

two pins of the Mains/AC Power plug.

• Check the cabinet for defects, to prevent touching of any inner parts by the customer.

• Where necessary, measure the waveforms and voltages

with (D) and without (E) aerial signal. Measure the voltages in the power supply section both in normal operation (G) and in stand-by (F). These values are indicated by means of the appropriate symbols.

3.3.2 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 kΩ).

• Resistor values with no multiplier may be indicated with either an “E” or an “R” (e.g. 220E or 220R indicates 220 Ω).

• All capacitor values are given in micro-farads (μ=× 10 nano-farads (n =× 10

• 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 on the Philips Spare Parts Web Portal.

3.3.3 Spare Parts

For the latest spare part overview, consult your Philips Spare Part web portal.

3.2 Warnings

• All ICs and many other semiconductors are susceptible to

electrostatic discharges (ESD w). 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.

• Be careful during measurements in the high voltage section.

• Never replace modules or other components while the unit is switched “on”.

• 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.

3.3 Notes

3.3.1 General

• Measure the voltages and waveforms with regard to the chassis (= tuner) ground (H), or hot ground (I), depending on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative. Measure them in the Service Default Mode with a colour bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 475.25 MHz for PAL, or 61.25 MHz for NTSC (channel 3).

2010-Jun-18

3.3.5 Lead-free Soldering

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

• Use only lead-free soldering tin. 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 a solder-tip temperature of at least 400°C. – To stabilize the adjusted temperature at the solder-tip. – To exchange solder-tips for different applications.

• Adjust your solder tool so that a temperature of around 360°C - 380°C is reached and stabilized at the solder joint. Heating time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400°C, otherwise wear-out of tips will increase drastically and flux-fluid will be destroyed. To avoid wear-out of tips, switch “off” unused equipment or reduce heat.

• Mix of lead-free soldering tin/parts with leaded soldering tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin.

3.3.6 Alternative BOM identification

It should be noted that on the European Service website, “Alternative BOM” is referred to as “Design variant”.

Precautions, Notes, and Abbreviation List

EN 7TPS2.1L LA 3.

The third digit in the serial number (example: AG2B0335000001) indicates the number of the alternative B.O.M. (Bill Of Materials) that has been used for producing the specific TV set. In general, it is possible that the same TV model on the market is produced with e.g. two different types of displays, coming from two different suppliers. This will then result in sets which have the same CTN (Commercial Type Number; e.g. 28PW9515/12) but which have a different B.O.M. number. By looking at the third digit of the serial number, one can identify which B.O.M. is used for the TV set he is working with. If the third digit of the serial number contains the number “1” (example: AG1B033500001), then the TV set has been manufactured according to B.O.M. number 1. If the third digit is a “2” (example: AG2B0335000001), then the set has been produced according to B.O.M. no. 2. This is important for ordering the correct spare parts! For the third digit, the numbers 1...9 and the characters A...Z can be used, so in total: 9 plus 26= 35 different B.O.M.s can be indicated by the third digit of the serial number.

Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 1 and 2 refer to the production centre (e.g. AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers to the Service version change code, digits 5 and 6 refer to the production year, and digits 7 and 8 refer to production week (in example below it is 2006 week 17). The 6 last digits contain the serial number.

3.3.7 Board Level Repair (BLR) or Component Level Repair (CLR)

If a board is defective, consult your repair procedure to decide if the board has to be exchanged or if it should be repaired on component level. If your repair procedure says the board should be exchanged completely, do not solder on the defective board. Otherwise, it cannot be returned to the O.E.M. supplier for back charging!

3.3.8 Practical Service Precautions

• It makes sense to avoid exposure to electrical shock.

While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.

• Always respect voltages. While some may not be

dangerous in themselves, they can cause unexpected reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution.

6.1 General Alignment Conditions

Perform all electrical adjustments under the following conditions:

• Power supply voltage: 220 - 240 V

• Connect the set to the mains via an isolation transformer with low internal resistance.

• Allow the set to warm up for approximately 15 minutes.

• Measure voltages and waveforms in relation to correct ground (e.g. measure audio signals in relation to AUDIO_GND). Caution: It is not allowed to use heatsinks as ground.

• Test probe: Ri > 10 MΩ, Ci < 20 pF.

• Use an isolated trimmer/screwdriver to perform alignments.

/ 50 ± 3 Hz.

6.2 Hardware Alignments

Not applicable.

6.3 Software Alignments

With the software alignment in “Factory” mode, the tuner and RGB settings can be aligned. To store the data: use on the RC the “MENU” button to switch to the main menu and then switch to “Stand-by” mode.

6.3.1 White Alignment

Before alignment, choose “MENU” -> “Picture” and set:

• “Brightness” to “50”.

• “Contrast” to “100”.

Then enter “Factory/SAM” mode to start the alignments.

When a color analyzer is available:

• Measure with a calibrated (phosphor- independent) color analyzer (e.g Minolta CA-210) in the center of screen Consequently, the measurement needs to be done in a dark environment.

• Select a COLOR TEMPERATURE (e.g. COOL, NORMAL, or WARM).

• Adjust the correct x,y coordinates (while holding one of the White point registers R, G or B on “127”) by means of decreasing the value of one or two other white points to the correct x,y coordinates (see table “White D alignment values xx”).

• Repeat this step for all color temperatures that need to be aligned.

• When finished, press STANDBY on the RC to store the aligned values to the NVM.

y 0.278 ± 0.004 0.291 ± 0.004 0.319 ± 0.004

If no color analyzer is available, you can use the default values. This is the next best solution. The default values are average values coming from production (statistics).

• Select a COLOR TEMPERATURE (e.g. COOL, NORMAL, or WARM).

• Set the RED, GREEN and BLUE default values according to the values in the “Tint settings” table.

• When finished, press STANDBY on the RC, to store the aligned values to the NVM.

6.3.2 Input Adjustment

1. Apply a color bar pattern (see below) to the input that must be aligned, and set “Brightness” and “Contrast” to 50%.

2. Enter “Factory/SAM” mode to start the alignments.

3. Select the source to align: TV/CVI1/CVI2/VGA/HDMI1/AV IN/AV side.

4. Activate the “Auto Color” function for auto ADC Offset and ADC Gain alignment. Check if scales are distinguishable.

5. Perform this alignment for all sources.

6.4 Reset of Repaired SSB

A very important issue towards a repaired SSB from a service repair workshop, implies the reset of the NVM on the SSB.

A repaired SSB in service should get the service Set Type “00PF0000000000” and Production Code “00000000000000”. Also the virgin bit is to be set. To set all this, you can use the ComPair tool.

Due to the compensation needed for the backlight of these TV sets, the item “Backlight time” value, stored in NVM, must be reset in a spare SSB with the original value of the TV set. “Backlight time” value can be found in the SAM (062596 + info button).

In case of a display replacement, reset the “Backlight time” to “0”, or to the operation hours of the replacement display.
