Safety Instructions, Warnings, and Notes EN 5FM242 AA 2.

2. Safety Instructions, Warnings, and Notes

2.1 Safety Instructions

Safety regulations require that during a repair:Connect the set to the mains via an isolation transformer(> 800 VA).

Do not operate the monitor without the front glass plate.One function of this glass plate is to absorb IR radiation.Without this glass plate, the level of radiation coulddamage your eyes.

Replace safety components, indicated by the symbol ,only by components identical to the original ones.

Safety regulations require that after a repair, the set must bereturned in its original condition. Pay, in particular, attention tothe following points: Route the wire trees correctly and fix them with the

mounted cable clamps. Check the insulation of the mains lead for external

damage. Check the electrical DC resistance between the mains plug

and the secondary side (only for sets which have a mainsisolated power supply):1. Unplug the mains cord and connect a wire between the

two pins of the mains plug.2. Set the mains switch to the 'on' position (keep the

mains cord unplugged!).3. Measure the resistance value between the pins of the

mains plug and the metal shielding of the tuner or theaerial connection on the set. The reading should bebetween 4.5 M and 12 M .

4. Switch 'off' the set, and remove the wire between thetwo pins of the mains plug.

Check the cabinet for defects, to avoid touching of anyinner parts by the customer.

2.2 Warnings

All ICs and many other semiconductors are susceptible toelectrostatic discharges (ESD ). Careless handlingduring repair can reduce life drastically. Make sure that,during repair, you are connected with the same potential asthe mass of the set by a wristband with resistance. Keepcomponents and tools also at this same potential.Available ESD protection equipment:

Complete kit ESD3 (small tablemat, wristband,connection box, extension cable and earth cable) 4822310 10671.

Wristband tester 4822 344 13999. 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 acircuit becoming unstable.

2.3 Notes

Clean the glass plate in front of the plasma display with aslightly humid cloth. If, due to circumstances, there is somedirt between the glass plate and the plasma display, thismust be cleaned by a qualified service engineer (seesection Mechanical Instructions).

Measure the direct voltages and oscillograms with regardto the chassis ground ( ), or hot ground ( ) as this iscalled.

The direct voltages and oscillograms shown in thediagrams are indicative. Measure them in the ServiceDefault Mode (see section Service Modes).

Where necessary, measure the voltages in the powersupply section both in normal operation ( ) and in standby( ). These values are indicated by means of theappropriate symbols.

The semiconductors indicated in the circuit diagram and inthe parts lists, are interchangeable per position with thesemiconductors in the unit, irrespective of the typeindication on these semiconductors

2.3.1 Schematic Notes

All resistor values are in ohms and the value multiplier isoften used to indicate the decimal point location (e.g. 2K2indicates 2.2 kOhm).

Resistor values with no multiplier may be indicated witheither an 'E' or an 'R' (e.g. 220E or 220R indicates 220Ohm).

All Capacitor values are expressed in Micro-Farads ( =x10 -6), Nano-Farads (n = x10 -9), or Pico-Farads (p = x10 -12).

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

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

The correct component values are listed in the ElectricalReplacement Parts List. Therefore, always check this listwhen there is any doubt.

2.3.2 Rework on BGA ICs

General Although (LF)BGA assembly yields are very high, there maystill be a requirement for component rework. By rework, wemean the process of removing the component from the PWB

and replacing it with a new component. If an (LF)BGA isremoved from a PWB, the solder balls of the component aredeformed drastically so the removed (LF)BGA has to bediscarded.

Device removal As is the case with any component, it is essential whenremoving an (LF)BGA that the board, tracks, solder lands, orsurrounding components are not damaged. To remove an(LF)BGA, the board must be uniformly heated to a temperatureclose to the reflow soldering temperature. A uniformtemperature reduces the chance of warping the PWB.To do this, we recommend that the board is heated until it iscertain that all the joints are molten. Then carefully pull thecomponent off the board with a vacuum nozzle. For the

appropriate temperature profiles, see the IC data sheet.

Area preparation When the component has been removed, the vacant IC areamust be cleaned before replacing the (LF)BGA.Removing an IC often leaves varying amounts of solder on themounting lands. This excessive solder can be removed witheither a solder sucker or solder wick. The remaining flux can beremoved with a brush and cleaning agent.After the board is properly cleaned and inspected, apply flux onthe solder lands and on the connection balls of the (LF)BGA.Note: Do not apply solder paste, as this has shown to result inproblems during re-soldering.


6/90

Safety Instructions, Warnings, and NotesEN 6 FM242 AA2.

Device replacement The last step in the repair process is to solder the newcomponent on the board. Ideally, the (LF)BGA should bealigned under a microscope or magnifying glass. If this is notpossible, try to align the (LF)BGA with any board markers.To reflow the solder, apply a temperature profile according tothe IC data sheet. So as not to damage neighbouringcomponents, it may be necessary to reduce sometemperatures and times.

ComPairhas three big advantages: ComPair helps you to quickly get an understanding on how

to repair the chassis in a short time by guiding yousystematically through the repair procedures.

ComPair allows very detailed diagnostics (on I 2C level) andis therefore capable of accurately indicating problem areas.You do not have to know anything about I 2C commandsyourself because ComPair takes care of this.

ComPair speeds up the repair time since it canautomatically communicate with the chassis (when themicroprocessor is working) and all repair information isdirectly available. When ComPair is installed together withthe SearchMan electronic manual of the defective chassis,schematics and PWBs are only a mouse click away.

5.4.2 Specifications

ComPair consists of a Windows based faultfinding program,and an RS232 cable between PC and the (defective) product.

The ComPair faultfinding program is able to determine theproblem of the defective monitor. ComPair can gatherdiagnostic information in two ways: Automatic (by communication with the monitor): ComPair

can automatically read out the contents of the entire errorbuffer. Diagnosis is done on I2C level. ComPair can sendand receive commands to the micro controller of themonitor, and so can access the I2C bus of the monitor. Inthis way, it is possible for ComPair to communicate (readand write) to devices on the I2C busses of the FTV monitor.

Manually (by asking questions to you): Automaticdiagnosis is only possible if the micro controller of themonitor is working correctly and only to a certain extend.When this is not the case, ComPair will guide you throughthe faultfinding tree by asking you questions (e.g. Does thescreen give a picture? Click on the correct answer: YES /NO ) and showing you examples (e.g. Measure test-pointF7 and click on the correct oscillogram you see on theoscilloscope ). You can answer by clicking on a link (e.g.

text or a waveform picture) that will bring you to the nextstep in the faultfinding process.

By a combination of automatic diagnostics and an interactivequestion / answer procedure, ComPair will enable you to findmost problems in a fast and effective way. Beside fault finding, ComPair provides some additionalfeatures like: Software upgrading (upload possible to OTC and PW

Scaler). Emulation of the (European) Dealer Service Tool (DST). If both ComPair and SearchMan (Electronic Service

Manual) are installed, all the schematics and the PWBs ofthe set are available by clicking on the appropriatehyperlink. Example: Measure the DC-voltage on capacitorC2228 (Schematic/Panel) of the SCAVIO panel. Click onthe 'Panel' hyperlink to automatically show the PWB with ahighlighted capacitor C2568. Click on the 'Schematic'hyperlink to automatically show the position of thehighlighted capacitor.

5.4.3 How to Connect

1. First, install the ComPair Browser software on your PC(read the installation instructions carefully).2. Connect an RS232 interface cable between a free serial

(COM) port on your PC and the RS232 connector on theFM242 plasma monitor.

3. Switch the plasma monitor 'off' and 'on' again (with theMains switch).

4. Start the ComPair program and follow the instructions. Note: once the set is in ComPair mode, the front LED will blinkred, at a frequency of 0.3 Hz.

5.4.4 How to Order

ComPair order codes: Starter kit ComPair32 software (registration version): 3122

785 60040. ComPair32 CD (update): 3122 785 60070. Starter kit SearchMan32 software: 3122 785 60050. SearchMan32 CD (update): 3122 785 60080. Note: The RS232 cable is not included. It is a standard cable(9p sub-D male-to-female) that can be obtained by a computerstore. It is supplied however with the ComPair interface (4822727 21631), necessary for servicing other Philips TVs.

5.5 Error Buffer

The error code buffer contains all detected errors since the lasttime the buffer was erased. The buffer is written from left toright. When an error occurs that is not yet in the error codebuffer, it is written at the left side and all other errors shift oneposition to the right.

5.5.1 How to Read the Error Buffer

Use one of the following methods: On screen via the SAM (only if you have a picture).

Examples: Errors: 6 0 0 0 0, error code 6 is the last and only

detected error. Errors: 9 6 0 0 0, error code 6 was first detected and

error code 9 is the last detected (newest) error.

Via the blinking LED procedure (when you have nopicture). See paragraph The blinking led procedure. Via ComPair.

5.5.2 How to Clear the Error Buffer

The error code buffer is cleared in the following cases:By activation of the 'Reset error buffer' command in theSAM menu.

When you transmit the code 062599 with a standardremote control transmitter.

5.5.3 Error Codes

Table 5-1 Error code overview

Notes: In case of non-intermittent faults, clear the error buffer

before you begin the repair. This to ensure that old errorcodes are no longer present.

If possible, check the entire contents of the error buffer. Insome situations, an error code is only the result of anothererror code and not the actual cause (e.g., a fault in theprotection detection circuitry can also lead to a protection).

In case error 70 occurs, the belonging over-voltage linecause can be located via measuring. (via measuring all 4voltages simultaneously with an oscilloscope). Chosen

FM242-workshops will be trained how to do so. (specialdocument will be generated for this).

5.6 The Blinking LED Procedure

Via this procedure, you can make the contents of the errorbuffer visible via the front LED (orange colour).This isespecially useful when there is no picture. When no errors are

present, the LED will stay green. When the SDM is entered, or when code 062500 is enteredwith the remote control, the LED will blink the contents of theerror-buffer.

Error-codes 10 are shown as follows:1. n long blinks of 750 ms, which is/are an indication of the

decimal digit,2. a pause of 1.5 s,3. n short blinks (n = 1-9),4. when all the error-codes are displayed, the sequence

finishes with a LED blink of 3 s,5. the sequence starts again.

Example of error buffer: 12 9 6 0 0 After entering SDM:1. 1 long blink of 750 ms followed by a pause of 1.5 s,2. 2 short blinks followed by a pause of 3 s,3. 9 short blinks followed by a pause of 3 s,4. 6 short blinks followed by a pause of 3 s,5. 1 long blink of 3 s to finish the sequence,6. the sequence starts again.

5.7 Protections

You can read the error codes of the error buffer via the servicemenu (SAM), the blinking LED procedure, or via ComPair. If afault situation is detected an error code will be generated and ifnecessary, the set will be put in the protection mode. Blinkingof the red LED at a frequency of 5 Hz indicates the protectionmode.In some error cases, the microprocessor does not put the setin the protection mode. The error codes are indicated by anorange front LED.

To get a quick diagnosis the chassis has three service modesimplemented: The Customer Service Mode (CSM): easy way to read out

the status of the set. The Service Default Mode (SDM): start-up of the set in a

predefined way. The Service Alignment Mode (SAM): adjustment of the set

via a menu and with the help of test patterns.

Exceptional protection situationThere exists one protection (due to too high internal set-temperature), where the set does not switch to protection-mode but to Standby-mode. This protection is not logged intothe error-buffer.When the set becomes too warm, an On Screen Display-message will be showed set is going to switch to Standby. Aftersome time set can be switched on again. (It is very unlikely thiswill happen. For that reason this performance has beenaccepted).

5.8 Repair Tips

If one of the errors of the error buffer points to a defectivesupply, then the supply-panel must be send for central repair.If the symptoms (still to be communicated; e.g. when VS-valueis too high some pixels do not extinguish, when VS-value is toolow some pixels do not enlighten) match with a possiblemisalignment of a supply-line, this supply-line could bechecked, and re-aligned.Only do this if there is a slight spec-violation.In case it does not help, re-align to the previous wrong setting,to keep cause-image in tact, for central repair workshop.Replace supply panel by a new one, and match the supply withthe pdp. (See alignment instructions in chapter Alignments).

8. Alignments

Index of this chapter:1. General Alignment Conditions2. Hardware Alignments3. Software Alignments and Settings Note: The Service Default Mode (SDM) and Service AlignmentMode (SAM) are described in chapter Service Modes.Menu navigation is done with the 'CURSOR UP, DOWN, LEFTor RIGHT' keys of the remote control transmitter.

8.1 General Alignment Conditions

Perform all electrical adjustments under the followingconditions: Mains voltage and frequency: 220 V AC / 50 Hz unless

otherwise stated. Connect the set to the Mains via an isolation transformer. Allow the set to warm up for approximately 20 minutes. Measure the voltages and waveforms in relation to chassis

ground (with the exception of the voltages on the primary

side of the power supply). Never use the cooling fins/platesas ground.

Test probe: Ri > 10 M , Ci < 2.5 pF. Use an isolated trimmer/screwdriver to perform the

alignments. Use a VGA-generator or a Personal Computer (contact yourNational Service Organisation for the necessary test patternfiles) as test pattern generator and connect it to the VGA1 inputof the FM242 plasma monitor. When you use a PC, startMicrosoft PowerPoint (or Paintbrush), and load the mentionedfile. Then display the picture as full screen.

8.2 Hardware Alignments

There no alignments needed, except in care the pdp has beenexchanged or the pdp-supply has been exchanged.In that case the both must be matched.

Figure 8-1 Supply Alignment

AlignmentsEN 68 FM242 AA8.

Procedure: See figure above The 6 pot meters influencing VSB, 3.3SBSW, VCC, D5V,

8V6, VFAN are not critical for matching. In case of doubtvalues can be checked versus mentioned voltages.

The 5 pot meters VS, VA, VSET, VE, VSC have to bematched with the values displayed on the pdp-label.

Start with aligning pot meter VR8008 to adjust VS and thenrespectively VR8010 (VA), VR8003 (VSET), VR8005 (VE),VR8004 (VSCAN)

To double check, repeat whole sequence again, to checkright value

8.3 Software Alignments
