Safety Instructions, Warnings, and Notes LC4.2E AA 2. EN 5 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). • 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.
EN 6 2. LC4.2E AA Safety Instructions, Warnings, and Notes 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. So as not to damage neighbouring components, it may be necessary to reduce some temperatures and times.

Service Modes, Error Codes, and Fault Finding communicate (read and write) to devices on the I2C busses of the TV-set. • Manually (by asking questions to you): Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extend. When this is not the case, ComPair will guide you through the faultfinding tree by asking you questions (e.g. Does the screen give a picture? Click on the correct answer: YES / NO) and showing you examples (e.g.

Menu navigation is done with the cursor Up, Down, Left or Right keys of the remote control transmitter. 8.1 8.2 There are no hardware alignments foreseen for the LCD-TV. 8.3 General Alignment Conditions Software Alignments With the software alignments of the Service Alignment Mode (SAM) the geometry, white tone and tuner (IF) can be aligned.
EN 64 8.3.2 8. Alignments LC4.2E 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 Sound EN 65 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. Select the option byte (OP1.. OP7) with the Menu Up/ Down keys, and enter the new value. No adjustments needed for sound.
