Safety Instructions, Warnings, and Notes Index of this chapter: 2.1 Safety Instructions 2.2 Warnings 2.3 Notes • 2.1 Safety Instructions Safety regulations require the following 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.
PAGE 7
Safety Instructions, Warnings, and Notes • 2.3.5 To avoid wear-out of tips, switch “off” unused equipment or reduce heat. Mix of lead-free soldering tin/parts with leaded soldering tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin. Alternative BOM identification The third digit in the serial number (example: AG2B0335000001) indicates the number of the alternative B.O.M.

Service Modes, Error Codes, and Fault Finding LC7.1E LA 5. EN 17 During this algorithm, the NVM-content must be filtered, because several items in the NVM are TV-related and not SSBrelated (e.g. Model and Prod. S/N). Therefore, “Model” and “Prod. S/N” data is changed into “See Type Plate”. In case a call centre or consumer reads “See Type Plate” in CSM mode, he needs to look to the side/bottom sticker to identify the set, for further actions.

Service Modes, Error Codes, and Fault Finding 5.2.3 Purpose • To change option settings. • To display / clear the error code buffer. • To perform alignments. How to Activate To activate SAM, use one of the following methods: • Press the following key sequence on the remote control transmitter: “062596" directly followed by the OSD/ STATUS/INFO/i+ button (it depends on region which button is present on the RC). Do not allow the display to time out between entries while keying the sequence.

Service Modes, Error Codes, and Fault Finding 5.5 The Blinking LED Procedure 5.5.1 Introduction The software is capable of identifying different kinds of errors. Because it is possible that more than one error can occur over time, an error buffer is available, which is capable of storing the last five errors that occurred. This is useful if the OSD is not working properly. 5.7.

The list contains references to the signals within all schematics of a PWB. It replaces the text references currently printed next to the signal names in the schematics. These printed references are created manually and are therefore not guaranteed to be 100% correct.

Some filters can be switched to another standard, what makes them suitable for applications in multi-standard platforms.

EN 78 9. LC7.1E LA Circuit Descriptions, Abbreviation List, and IC Data Sheets “Block diagram video processing - AP version” shows the input and output signals to and from the Trident Video Processor in AP applications. During analogue reception, a CVBS signal coming from the analogue front-end is fed to the video processor via pin CVBS1. No digital reception (DVB-T) reception is foreseen in AP region.

Circuit Descriptions, Abbreviation List, and IC Data Sheets Three I2S-inputs for signals (“DATA”, “CLK” and “WS”) coming from the HDMI interface • Five analogue inputs: for CVI1, CVI2, AV1, AV2, DTV (China) and PC audio • Loudspeaker output path • Headphone output path • Monitor output path (WYSIWYG). Digital audio signals coming from HDMI sources are directly fed to the MSP via the I2S_DA_IN3, I2S_WS3 and I2S_CL3 lines. This ensures a “true digital path”.
