2.1 Safety Instructions

Safety regulations require that during a repair:Connect the set to the AC Power via an isolationtransformer (> 800 VA).Replace safety components, indicated by the symbol ,only by components identical to the original ones. Anyother component substitution (other than original type) mayincrease risk of fire or electrical shock hazard.

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 themounted cable clamps.Check the insulation of the AC Power lead for externaldamage.Check the strain relief of the AC Power cord for properfunction.Check the electrical DC resistance between the AC Powerplug and the secondary side (only for sets which have a ACPower isolated power supply):1. Unplug the AC Power cord and connect a wire

between the two pins of the AC Power plug.2. Set the AC Power switch to the "on" position (keep the

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

AC Power plug and the metal shielding of the tuner orthe aerial connection on the set. The reading should bebetween 4.5 Mohm and 12 Mohm.

4. Switch "off" the set, and remove the wire between thetwo pins of the AC Power 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.Be careful during measurements in the high voltagesection.Never replace modules or other components while the unitis 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

2.3.1 General

1. Measure the voltages and waveforms with regard to thechassis (= tuner) ground ( ), or hot ground ( ), dependingon the tested area of circuitry. The voltages and waveformsshown in the diagrams are indicative. Measure them in theService Default Mode (see chapter 5) with a color barsignal and stereo sound (L: 3 kHz, R: 1 kHz unless statedotherwise) and picture carrier at 475.25 MHz for PAL, or61.25 MHz for NTSC (channel 3).2. Where necessary, measure the waveforms and voltageswith ( ) and without ( ) aerial signal. Measure thevoltages in the power supply section both in normaloperation ( ) and in stand-by ( ). These values areindicated by means of the appropriate symbols.3. The semiconductors indicated in the circuit diagram and in

-6

-9 -12

the parts lists, are interchangeable per position with thesemiconductors in the unit, irrespective of the typeindication on these semiconductors.4. Manufactured under license from Dolby Laboratories."Dolby" and the "double-D symbol", are trademarks ofDolby Laboratories.

1. All resistor values are in ohms and the value multiplier isoften used to indicate the decimal point location (e.g. 2K2indicates 2.2 kohm).2. Resistor values with no multiplier may be indicated witheither an "E" or an "R" (e.g. 220E or 220R indicates 220ohm).3. All capacitor values are given in micro-farads (u= x10 ),nano-farads (n= x10 ), or pico-farads (p= x10 ).4. Capacitor values may also use the value multiplier as thedecimal point indication (e.g. 2p2 indicates 2.2 pF).5. An "asterisk" (*) indicates component usage varies. Referto the diversity tables for the correct values.6. The correct component values are listed in the ElectricalReplacement Parts List. Therefore, always check this listwhen there is any doubt.

GeneralAlthough (LF)BGA assembly yields are very high, there may still bea requirement for component rework. By rework, we mean theprocess of removing the component from the PWB and replacing itwith a new component. If an (LF)BGA is removed from a PWB, thesolder balls of the component are deformed drastically so theremoved (LF)BGA has to be discarded.

Device RemovalAs is the case with any component that, it is essential whenremoving an (LF)BGA, the board, tracks, solder lands, orsurrounding components are not damaged. To remove an(LF)BGA,the board must be uniformly heated to a temperature close to thereflow soldering temperature. A uniform temperature reduces thechance of warping the PWB.To do this, we recommend that theboard is heated until it is certain that all the joints are molten.Then carefully pull the component off the board with a vacuumnozzle. For the appropriate temperature profiles, see the IC datasheet.

Area PreparationWhen the component has been removed, the vacant IC area mustbe cleaned before replacing the (LF)BGA.Removing an IC oftenleaves varying amounts of solder on the mounting lands. Thisexcessive solder can be removed with either a solder sucker orsolder wick. The remaining flux can be removed with a brush andcleaning agent.After the board is properly cleaned and inspected,apply flux on the solder lands and on the connection balls ofthe (LF)BGA.Note: Do not apply solder paste, as this has shown to result inproblems during re-soldering.

Device ReplacementThe last step in the repair process is to solder the new componenton the board. Ideally, the (LF)BGA should be aligned under amicroscope or magnifying glass. If this is not possible, try to alignthe (LF)BGA with any board markers. To reflow the solder, apply atemperature profile according to the IC data sheet. So as not todamage neighbouring components, it may be necessary to reducesome temperatures and times.

5TPF1.4A LA

This sign normally has a diameter of 6 mm, but if there is lessspace on a board also 3 mm is possible.In case of doubt wether the board is lead-free or not (or withmixed technologies), you can use the following method:1. Always use the highest temperature to solder, when usingSAC305 (see also instructions below).2. De-solder thoroughly (clean solder joints to avoid mix oftwo alloys).

: For BGA-ICs, you must use the correct temperatureprofile,which is coupled to the 12NC. For an overview of theseprofiles, visit the website(needs subscription, but is not available for all regions)You will find this and more technical information within the"Magazine", chapter "Workshop information".For additional questions please contact your local repairhelpdesk.

Caution

www.atyourservice.ce.philips.com

Due to lead-free technology some rules have to be respectedby the workshop during a repair:1. Use only lead-free soldering tin . If lead-free solder pasteis required,please contact the manufacturer of your solderingequipment. In general, use of solder paste withinworkshops should be avoided because paste is not easy tostore and to handle.2. Use only adequate solder tools applicable for lead-freesoldering tin. The solder tool must be able-To reach at least a solder-tip temperature of 400 C.-To stabilise the adjusted temperature at the solder-tip.-To exchange solder-tips for different applications.3. Adjust your solder tool so that a temperature around 360 C- 380 C is reached and stabilised at the solder joint.Heating time of the solder-joint should not exceed ~ 4 sec.Avoid temperatures above 400 C, otherwise wear-out oftips will rise drastically and flux-fluid will be destroyed. Toavoid wear-out of tips, switch "off" unused equipment orreduce heat.4. Mix of lead-free soldering tin/parts with leaded solderingtin/parts is possible but PHILIPS recommends strongly toavoid mixed regimes. If not to avoid, clean carefully thesolder-joint from old tin and re-solder with new tin.5. Use only original spare-parts listed in the Service-Manuals.Not listed standard material (commodities) has to bepurchased at external companies.6. Special information for lead-free BGA ICs: these ICs will bedelivered in so-called "dry-packaging" to protect the ICagainst moisture. This packaging may only be openedshort before it is used (soldered). Otherwise the body of theIC gets "wet" inside and during the heating time thestructure of the IC will be destroyed due to high (steam-)pressure inside the body. If the packaging was openedbefore usage, the IC has to be heated up for some hours(around 90 C ) for drying (think of ESD-protection !).

7. For sets produced before 1.1.2005, containing leadedsoldering tin and components, all needed spare parts willbe available till the end of the service period. For the repairof such sets nothing changes.

Do not re-use BGAs at all!

Fig 2-1 Lead-free logo

2.3.4 Lead Free Solder

Philips CE is going to produce lead-free sets (PBF) from1.1.2005 onwards.Lead-free sets will be indicated by the PHILIPS-lead-free logoon the Printed Wiring Boards (PWB):

1.While some sources are expected to have a possibledangerous impact, others of quite high potential are oflimited current and are sometimes held in less regard.2. While some may not bedangerous in themselves, they can cause unexpectedreactions - reactions that are best avoided. Before reachinginto a powered TV set, it is best to test the high voltageinsulation. It is easy to do, and is a good service precaution.

2.3.5 Practical Service Precautions

It makes sense to avoid exposure to electrical shock.

Always respect voltages.

the TV will turn off.

Check the buttons.Check the button on the remote control.If you're attempting to hook up auxiliary

equipment, check the audio jack connections.

Check whether AV and S-Video sockets connectedsimultaneously. If they are, disconnect the S-Videosocket. AV signal automatically overrides the S-Videosignal if both sockets are connected simultaneously.

Unplug socket for S-Video connection. Reconnectthe S-Video socket of the TV carefully to the VCRsocket.

If using a cable box with RF only type connections,the signal coming from the cable box will beproduced in only.Check Sound control setting. Change setting to

Stereo.

Check the batteries. Place lithium cell in theremote. Be sure the (+) and (-) ends of the batteriesline up as marked inside the battery compartment.Clean the remote control and the remote control

sensor window on the TV.Check the TV power cord. Unplug the TV, wait 10

seconds,then reinsert the plug into the outlet andpush the button again.Be sure the fuse is not blown on the AC power

strip, if one is being used.Check to be sure the TV outlet is not on a wall

switch.Be sure that the remote is in the correct operating

mode.Be sure the remote is pointed at the Remote

Sensor Window on the TV. See page 2 of the QuickUse Guidefor details.

Repeat channel selection.Add the desired channel numbers (using the

control) into the TV's memory.Run the Auto Program feature to find all availablechannels.

9.2Circuit Description

General DescriptionThis LCD TV monitor using FL-1 platform. It can support PC analog signal ( via 15 pin D-Sub input ) and TV

signal. It support PIP function that is TV picture on PC graphic or TV picture on DVI /HDCP. Its output resolution isup to 1366X768 75Hz for WXGA panel.

It can support DVI HDCP digital signal input and also support TV (RF) , CVBS/ RG B signal ( from SCART1 I/Ofor Europe model ) ,CVBS / YC ( from SCART2 I/O for Europe model ) , CVBS/YPbPr ( from Cinch I/O for Non-Europe model ) , CVBS/YC ( from Cinch and S terminal I/O for Non-Europe model ) , and also have side I/O , supportCVBS/YC and Headphone for User easy used .

And It can also support Y Pb Pr signal input (from Cinch I/O) for 480I, 480P, 720P, 1080i 60Hz and 576I, 576P,720P, 1080I 50Hz HDTV format input.

Note : For Chinch I/O model two components input is provided one for 480I,480P and 576I, 576P the other forthe 480I, 480P, 720P,1080i 60Hz and 576I, 576P, 720P, 1080I 50Hz HDTV format input.It also have PVR output function , support and monitor all the CVBS signal output with L/R sound.

This LCD monitor TV use MST51512 as Scaler engine, which has embedded Analog D-sub, digital DVI decoder,scaling input signal for panel, OSD and simple 3D de-interlace. The extra SDRAM is to accomplish video frame rateconversion and PIP function.

The external CPU can be used for back light control, RC receiver, keypad input, I/O switch control , IICcommunication and TV tuning control, MSP34XX sound decoder control, SAA7119 video decoder control , ColumbusIC ( 3D- comb filter ) control , and Audio AMP TPA3004D sound control .

Video decoder SAA7119 is used for TV video processing and convert it with CCIR 601/16bits or 656/8bits digitalformat and send to Columbus IC for 3D comb filter processing and noise reduction processing , after that then sendto Scaler for de-interlace process.

One audio decoder MSP34XXG is used for TV sound processing, and output to Class D audio amplifierTPA3004D , then we can have 2 X10W audio output .

An option function in AP model Telttext display . Data decode is done by SAA5360, output RGB/FB is to videodecoder input for textoverlapping. In non-text model, this chip is N.C.

MM tuner is used to receive RF wave and output CVBS and 2nd IF signal. CVBS is to video decoder (SAA7119) forcolor process, 2nd IF is to sound decoder (MSP34x5) for audio process. The tuner control is via IIC ex. channel tuning.Fordifferent TV system, tuner and sound decoder have diversity as above.

Standard TV input (Tuner, S-video, CVBS, SCART) is processed by SAA7119, But YPbPr, SDTV and HDTV(480i,576i,480p,576p,720p,1080i), is done by scaler MST51512L/502L ADC. But the signal is still link to SAA7119 if PIP (videoin graph) functionis requested. Then all YPbPr signal processed by SAA7119 could be the PIP video source. (* May usedown sampling in HD0) MV protect is decoded by scaler.

Video decoder SAA7119, is in charge of color decoding, could support PAL, NTSC and SECAM world widesystem. Compare to SAA7118, SAA7119 improve some picture quality, like V-chip CC I2C read-back, LTI, CTI, skin tonecorrection(see task A), also the HD0 is supported .

Teltext function is for AP model, need a extra IC SAA5360. CVBS input, R/G/B, FB, out. Due to the SAA5360 requestinput signal 1Vrms and only one input channel, so the CVBS input source is from SAA7119 AOUT (CVBS out with 1Vrms).The R/G/B FB output into SAA7119 by AI22/AI32/AI42, and AI44 could overlay on any video source.Sound decoder MSP3415/45 is responsible to sound decode of tuner 2nd IF. It has one 2nd IF, two selectable audiosources input.

And one loudspeaker, one scart out. Due to the input port limitation, a MUX is added for AV source select( PC audioin is fix in SC1). If the post audio amplifier is gain fixed type then the volume adjust will be on MSP34XX.Scaler MST51502L/51512L besides scaling function, PIP, 3D de-interlacer, color enhance are major feature.Even de-interlacer is not so good but for static picture is enough to avoid image sticking.

The scaler structure limitation, the PIP source only from video port , 8 bits or 16 bits. The sub window /PIP size canenlarge to half screen.

MCU, NT68F632AL, is 128K flash ROM inside. Power control, RC5 I/O, and key function all done by here.All chip communication i
