31. When the component has been removed the vacant IC area must be cleaned before replacing the LF BGA Removing an IC often leaves varying amounts of solder on the mounting lands This excessive solder can be removed with either a solder sucker or solder wick The remaining flux can be removed with a brush and cleaning agent After the board is properly cleaned and inspected apply flux on the solder lands and on the connection balls of the LF BGA Note Do not apply solder paste as this has been shown to result in problems during re soldering Device Replacement The last step in the repair process is to solder the new component on the board Ideally the LF BGA should be aligned under a microscope or magnifying glass If this is not possible try to align the LF BGA with any board markers So as not to damage neighbouring components it may be necessary to reduce some temperatures and times More Information 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 Workshop Information Here you will find Information on how to deal with BGA ICs 2 4 4 Lead free Solder Philips CE is producing lead free sets PBF from 1 1 2005 onwards Identification The bottom line of a type plate gives a 14 digit serial number Digits 5 and 6 refer to the production year digits 7 and 8 refer to produc

Data Sheets LO4HA 9 First Part of Scan Pin 62 of the UOC delivers the horizontal drive signal for the Line Output stage This signal is a square pulse of line frequency 15402 is the flyback drive transformer This transformer de couples the line output stage from the UOC It has a direct polarization The flyback drive circuit works with the start up supply taken from 6V of the Aux supply and subsequently taking from VlotAux49V When the H drive is high TS7404 conducts and transformer 15402 starts to store energy The base of the line transistor TS7405 is low and therefore blocks The current in the deflection coil returns from diode D6404 Second Part of Scan When the H drive is low TS7404 does not conduct and the energy that is stored in the transformer will transfer to the secondary making the base of the Line Transistor high Then the Line Transistor starts to conduct The current in the deflection coil returns from the transistor in another direction Flyback At the moment the H drive becomes high the base of the Line Transistor becomes low Both the Line Transistor and the Flyback Diode will block There is an oscillation between the flyback capacitor C2412 and the deflection coil Because of the inductance of the LOT the Line Transistor cannot stop conducting immediately After the Line Transistor is out of conduction the flyback pulse is created The flyback capacitor charges until the current in the deflectio

Mannheim effect To prevent this from happening a circuit called Mannheim circuit is added This consists of C2415 R3404 R3417 and D6406 During the scan C2415 is charged via R3417 During the flyback the S correction parabola across the S Cap C2417 C2418 is in its most negative and D6406 conducts Thus C2415 is switched in parallel to C2417 C2418 during flyback As C2415 is much larger than C2417 C2418 the voltage across C2415 reduces the Mannheim effect oscillation Class D East West Driver To reduce the power loss of the normal used linear East West amplifier a class D East West circuit is used To achieve this the East West parabola waveform EW DRIVE from the Hercules frame frequency is sampled with a saw tooth line 9 3 3 9 3 4 frequency taken from the line aux output Then a series of width modulated pulses is formed via two inverted phase amplifiers filtered by an inductor which then directly drive the diode modulated line circuit East West Correction To achieve a good geometry dynamic S correction is needed The design is such that the tube yoke needs East West correction Besides that an inner pincushion is present after East West correction The line deflection is modulated with a parabolic voltage frame frequency In this way it is not so much at top and bottom and much more in the middle Upon entering the picture geometry menu in the SAM mode the following corrections will be displayed e EWW E
