2.4 Abbreviation List

2.1 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 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 M: and 12 M:.

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.

2.2 Warnings

• 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.

• 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.

2.3 Notes

2.3.1 General

• Measure the voltages and waveforms with regard to the chassis (= tuner) ground ( ), or hot ground ( ), depending on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative. Measure them in the Service Default Mode (see chapter 5) 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).

• Where necessary, measure the waveforms and voltages with ( ) and without ( ) aerial signal. Measure the voltages in the power supply section both in normal operation ( ) and in stand-by ( ). These values are indicated by means of the appropriate symbols.

2.3.2 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 k:).

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

• All capacitor values are given in micro-farads (P u10 nano-farads (n u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 in the Spare Parts List. Therefore, always check this list when there is any doubt.

2.3.3 BGA (Ball Grid Array) ICs

Introduction

For more information on how to handle BGA devices, visit this URL: www.atyourservice.ce.philips.com (needs subscription, not available for all regions). After login, select “Magazine”, then go to “Repair downloads”. Here you will find Information on how to deal with BGA-ICs.

BGA Temperature Profiles

For BGA-ICs, you must use the correct temperature-profile, which is coupled to the 12NC. For an overview of these profiles, visit the website www.atyourservice.ce.philips.com (needs subscription, but is not available for all regions) You will find this and more technical information within the “Magazine”, chapter “Repair downloads”. For additional questions please contact your local repair help desk.

2.3.4 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 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 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.

2.3.5 Alternative BOM identification

1 - 4

2.4 Abbreviation List

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

The third digit in the serial number (example: KX2B0835000001) indicates the number of the alternative B.O.M. (Bill Of Materials) that has been used for producing the specific AV set. In general, it is possible that the same AV model on the market is produced with e.g. two different types of display, coming from two different suppliers. This will then result in sets which have the same CTN (Commercial Type Number; e.g. MCM394/12) but which have a different B.O.M. number.

Also, it is possible that same model on the market is produced with two production centers, however their partslist is the same. In such case, no alternative B.O.M. will be created.

By looking at the third digit of the serial number, one can identify which B.O.M. is used for the set he is working with. If the third digit of the serial number contains the number “1” (example: KX1B033500001), then the set has been manufactured according to B.O.M. number 1. If the third digit is a “2” (example: KX2B0335000001), 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. LM is Arts), 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 2008 week 50). The 6 last digits contain the serial number.

2.3.6 Module Level Repair (MLR) 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!

2.3.7 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.
