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,

ly by components identical to the original ones. Any

on other component substitution (other than original type) may increase risk of fire or electrical shock hazard.

Safety regulations require that after a repa returned in its original condition. Pay in particular attention to the following points:

• Route the wire trees correctly and fix them with the

nted cable clamps.

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

• Check the electrical DC resistance between the Mains/AC Pow a Mains/AC Power isolated power supply):

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

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

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

• Measure the voltages and waveforms with regard to the chassis (= on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative.

3.3.5 Lead-free Soldering

Due to lead-free technology some rules h by the workshop during a repair:

• Use only lead-free soldering tin. 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

ldering tin. The solder tool must be able:

so – 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

- 380°C is reached and stabilized at the solder joint.

360°C 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 sold 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.

Precautions, Notes, and Abbreviation List

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 o identify which B.O.M. is used for the TV set he is working with. If the third digit of the serial n (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 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 SN is Lysomice, RJ is Kobierzyce), 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 2010 week 10 / 2010 week 17). The 6 last digits contain the serial number.

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

(CL

If a board is defective, consult your repair procedure if the board has to be exchanged or if it should be repaired on component level. If your repair procedure says the board shou 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. Wh dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard.

• Always respect vo 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.

4.2 Service Positions

For easy servicing of a TV set, the set should be put face down on a soft flat surface, foam buffers or other specific workshop tools. Ensure that a stable situation is created to perform measurements and alignments. When using foam bars take care that these always support the cabinet and never only the display. Caution: Failure to follow these guidelines can seriously damage the display! Ensure that ESD safe measures are taken.

4.3 Assembly/Panel Removal

5.1 Test Points

As most signals are digital, it will be difficult to measure waveforms with a standard oscilloscope. However, several key ICs are capable of generating test patterns, which can be controlled via ComPair. In this way it is possible to determine which part is defective.

Perform measurements under the following conditions:

• Service Default Mode.

• Video: Colour bar signal.

• Audio: 3 kHz left, 1 kHz right.

5.2 Service Modes

The Service Mode feature is split into four parts:

• Service Default Mode (SDM).

• Service Alignment Mode (SAM).

• Customer Service Mode (CSM).

• Computer Aided Repair Mode (ComPair).

CSM is a Service Mode that can be enabled by the consumer. CSM displays d forward to the dealer or call centre. In CSM mode, “CSM”, is displayed in the top right corner of the screen. The information provided in CSM and the purpose of CSM is to:

• Increase the home repair hit rate.

• Decrease the number of nuisance calls.

• Solve customer problems without home visit.

ComPair Mode is used for communication between a computer and a T engineer to quickly diagnose the TV set by reading out error codes, read and write in NVMs, communicate with ICs and the μP (PWM, registers, etc.), and by making use of a fault finding database. It will also be possible to up and download the software of the TV set via I ComPair has to be connected to the TV set via the ComPair connector, which will be accessible through the rear of the set (without removing the rear cover).

Note: For the new model range, a new remote control (RC) is used with some rename activation of the Service modes. For instance the old “MENU” button is now called “HOME” (or is indicated by a “house” icon).

5.4.1 ComPair

Introduction

ComPair (Computer Aided Repair) is a Service tool for Philips Cons

umer Electronics products. and offers the following:

1. ComPair helps to quickly get an understanding on how to repair the chassis in a short and effective

2. ComPair allows very detailed di capable of accurately indicating problem areas. No knowledge on I

C or UART commands is necessary,

because ComPair takes care of this.

3. ComPair speeds up the repair time since it can

tomatically communicate with the chassis (when the

au microprocessor is working) and all repair information is directly available.

4. ComPair features TV software up possibilities.

Specifications

ComPair consists of a Windows based fault find and an interface box between PC and the (defective) product. The ComPair II interface box is connected to the PC via an USB cable. For the TV chassis, the ComPair interface box and the TV communicate via a bi-directional cable via the service connector(s). The ComPair fault finding program is able to dete problem of the defective television, by a combination of automatic diagnostics and an interactive question/answer procedure.

. When inserting an empty USB memory stick, and downloading data to the stick, the TV will create this folder.

Note that when copying EDID data to the TV, all necessary EDID files must be in this folder While copying to

or from the USB “Repair” F

older to TV, the

files need to be named accordingly:

• Channel List: CM_TPS82E_LA_CK.BIN

• EDID 1: HDMI_1_EDID_TPM82E_LA_CK.BIN

• EDID 2: HDMI_2_EDID_TPM82E_LA_CK.BIN
