EN 4 2. LC4.1U 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.
PAGE 5
Safety Instructions, Warnings, and Notes Note: Do not apply solder paste, as this has 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. To reflow the solder, apply a temperature profile according to the IC data sheet.

Service Modes, Error Codes, and Fault Finding 5.2.3 LC4.1U 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 42 8.3.2 8. Alignments LC4.1U 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).
PAGE 43
Alignments 8.3.5 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 8.3.6 Options Options are used to control the presence/absence of certain features and hardware. How to change an Option Byte An Option Byte represents a number of different options. Changing these bytes directly makes it possible to set all options very fast. All options are controlled via seven option bytes.
