EN 4 2. LC4.1A AA Safety Instructions, Warnings, and Notes 2. Safety Instructions, Warnings, and Notes 2.1 • Safety Instructions Safety regulations require that 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, 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 Instructions, Warnings, and Notes • aligned under a microscope or magnifying glass. If this is not possible, try to align the (LF)BGA with any board markers. To reflow the solder, apply a temperature profile according to the IC data sheet. 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.

In the schematics test points are identified with a rectangle box around Fxxx or Ixxx.
EN 10 5. LC4.1A AA Service Modes, Error Codes, and Fault Finding • How to exit Switch the set to STANDBY by pressing the mains button on the remote control transmitter or the television set. If you turn the television set off by removing the mains (i.e., unplugging the television) without using the mains button, the television set will remain in SDM when mains is re-applied, and the error buffer is not cleared. 5.2.2 Service Alignment Mode (SAM) Purpose • To change option settings.
Service Modes, Error Codes, and Fault Finding 5.2.3 LC4.1A AA 5. EN 11 Customer Service Mode (CSM) 5.3 Problems and Solving Tips (Related to CSM) Purpose The Customer Service Mode shows error codes and information on the TV’s operation settings. The call centre can instruct the customer (by telephone) to enter CSM in order to identify the status of the set. This helps the call centre to diagnose problems and failures in the TV set before making a service call.
EN 12 5. LC4.1A AA Service Modes, Error Codes, and Fault Finding Black and white picture 5.4.2 ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product. The ComPair interface box is connected to the PC via a serial or RS232 cable. For this chassis, the ComPair interface box and the TV communicate via a bi-directional service cable via the service connector.
Service Modes, Error Codes, and Fault Finding 5.4.4 5.5.1 Error Codes 5.6 How To Read The Error Buffer Note: If you exit SAM by disconnecting the mains from the television set, the error buffer is not reset. 5.5.3 Error Codes In case of non-intermittent faults, write down the errors present in the error buffer and clear the error buffer before you begin the repair. This ensures that old error codes are no longer present.

EN 42 8.4.2 8. Alignments LC4.1A AA White Tone • In the White Tone sub menu the colour values for the colour temperature values can be changed. The colour temperature mode (Normal, Delta Cool, Delta Warm) or the colour (R, G, B) can be selected with the Right/ Left cursor keys. The mode or value can be changed with the Up/Down cursor keys. First the values for the Normal colour temperature should be selected. Range: 0-255, 128 represent the middle of the value (no offset difference).
Alignments 8.4.5 Sound No adjustments needed for sound. The default values for the audio alignments are: • QSS: On • FMI: Off • NICAM Alignment: 63 • Lip Sync: Off • DBE: Off 8.5 Option Settings Options are used to control the presence/absence of certain features and hardware. 8.5.1 How to change an Option Byte An Option Byte represents a number of different options.
