Alignments8.4.6 Required Software Versions Be aware that the software used in these TV sets is NOT similar to software used in the Mainstream LCD-TVs. Used software versions in this chassis are: LC4CHE1-1.xx (Hercules) S4CHEX1-1.xx (for Scaler 15 XGA resolution) S4CHEV1-1.xx (for Scaler 20 VGA resolution) Ensure that this software is used in these sets (available on the P4C service web site).

Installing a TV with the Wireless Smart-Loader Use a Wireless Smart-Loader programmed with the settings from a master TV of the same type. Be sure to use the same method of programming the Wireless Smart-Loader. It means that if you program the Wireless Smart-Loader using the wireless method, you have to use the same method to install the TV. 1. Wireless method (for LCD and CRT TVs): Turn on the TV, press the "MENU" Key on the Wireless Smart-Loader. 2. Wired method (for CRT TVs only): Turn on the TV set, connect the Wireless SmartLoader to the TV set using the accessory cable. Press the Volume - and + buttons on the TV set simultaneously for 3 seconds. Highlight SMARTLOADER TO TV. For wireless method: press the right arrow key on the Wireless Smart-Loader. For wired method: press the TV Remote Control. A number from 1-100 is displayed, indicating the data transfer completed percentage, from the Wireless Smart-Loader to the TV (100 = fully loaded). SMARTLOADER TO TV ||| -------## When data transfer is completed, ## = 100, the following menu appears for 3 seconds: TV READY > After which the following message appears: GOODBYE > The TV set goes to stand-by now and will start up automatically. The TV set is now installed and ready for use.

Hotel Mode Instructions (for iTV sets)For Installation Menu access, Remote Control (RC1683803) will be necessary.

8.5.1

The Benefits of the Hotel Mode This TV set is especially designed to operate in Hotel Mode. Hotel Mode offers the following benefits: Access to the User Menu can be blocked. This prevents users (e.g. guests) from changing or deleting channel settings and/or modifying picture and sound settings. Picture and sound settings can only be controlled via pre-programmed Smart Settings and buttons on the remote control. This ensures that TVs always start up correctly. A switch-on volume level and channel can be selected. After switching on, the TV always starts-up on the specified channel and volume level. The maximum volume level can be limited in order to prevent disturbance. Channels can be blanked. The keys VOLUME +/-, PROGRAM +/- and MENU, of the TV set can be blocked. Screen information can be suppressed.

8.4.5

Problems and Solutions: The message WRONG VERSION appears on the screen. The Wireless Smart-Loader contains a master TV installation set-up not compatible to the TV set to be set-up. Reprogram the Wireless Smart-Loader from a master TV set whose software version is compatible with the software version of the TV set to be set-up. The message I2C ERROR is displayed on the screen. Bad connection of RJ11 cable or wrong data transmission occurred, please try again. TV does not respond to the Wireless Smart-Loader. Check if the green LED lights up on the Wireless Smart-Loader when any button is pressed, and check if the batteries are in a good condition. When the red LED lights up, the batteries must be replaced. Try to bring the Wireless Smart-Loader closer to the infra red receiver of the TV set and try again.

8.5.2

Activating the Hotel Mode Setup Menu 1. Switch on the TV set and select a TV channel. 2. On the remote control, enter the following key combination: 319753, directly followed by the MUTE key. 3. The HOTEL MODE SETUP MENU appears on the screen. 4. Use the cursor keys to select and change the following settings: Table 8-1 Hotel Mode Setup MenuFunction HOTEL MODE ON CHANNEL CHANNEL BLANKED KEYBOARD LOCK MAX VOLUME ON VOLUME AUX VOLUME OSD DISPLAY MONITOR OUT ICONN MODE Possible selections ON /OFF 0..99, EXTERNALS ON/OFF ON/OFF 0..99 0..99 0..99 ON/OFF OFF OFF

Tips: Do not forget to write the software version and the type of the relevant master TV set on the sticker, attached to the backside of the Wireless Smart-Loader. In case of empty- or missing batteries, it is still possible to install TVs using the wired method of the Wireless Smart-Loader (for CRT TVs only). Without batteries, the Wireless Smart-Loader retains the stored information for ten years. Note: Before the Wireless Smart-Loader is stored for a long period of time, take out the batteries to prevent the contacts from corrosion. Wired Smart-Loading works with CRT TVs only. Wireless Smart-Loading works with both, Flat TVs and CRT TVs.

Figure 8-2 SAM Menu (example, actual alignment values might differ) 8.6.2 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). Then the offset values for the Delta Cool and Delta Warm mode can be selected. Note that the alignment values are non-linear. The range is: -50 to +50, 0 represents the middle value, (no offset difference). Input signal strength: 10 mV_rms (80 dBV) terminal voltage. Input injection point: Aerial input.

AlignmentsAlignment Method Initial Set-up 12 minutes soaking time before carrying out alignments. Incredible Picture/Contrast+ and Active Control & Light Sensor must be switched off for proper tracking. Set all colour temperature settings to their initial values, i.e. Red=180; Green=180; Blue=180. The offset values for Cool and Warm should be preloaded into NVM. The alignment is done for Normal only. Method of alignments 1. Place the colour sensor of the meter at the centre of the screen with standard orientation (at 0 degree orientation). 2. Set the meter in (T, delta UV, Y) mode. 3. Set Brightness and Colour to nominal (Factory mode, Brightness at 60). 4. Set Colour Temp to Normal. 5. Set Contrast to make the light output Y on the meter 250 nit +/-10%. 6. Set Green to 128. 7. Adjust Red and Blue to bring delta UV and T to the value as in the table. 8. Repeat the procedure if necessary to obtain the values as in the table. Table 8-2 Colour temperaturesColour temp.

LC4.1E AC

Circuit Descriptions, Abbreviation List, and IC Data Sheets 9.4 Tuner and IFOn models with FM radio, an NXP UR13xx Tuner with second input (for FM Radio) is used in the TV board. The SIF and FM signals are decoded by the Hercules. Tuning is done via I2C. 9.4.1 Video IF Amplifier The IF-filter is integrated in a SAW (Surface Acoustic Wave) filter. One for filtering IF-video (1328) and one for IF-audio (1330). The type of these filters is depending of the standard(s) that has to be received. The output of the tuner is controlled via an IF-amplifier with AGC-control. This is a voltage feedback from pin 31 of the Hercules to pin 1 of the tuner. The AGC-detector operates on top sync and top white level. AGC take-over point is adjusted via the service alignment mode Tuner - AGC. If there is too much noise in the picture, then it could be that the AGC setting is wrong. The AGC-setting could also be mis-aligned if the picture deforms with perfect signal; the IF-amplifier amplifies too much.

The PLL tuner delivers the IF-signal, via audio and video SAWfilters, to the Video Signal Processor and FLASH embedded TEXT/Control/Graphics Micro Controller TDA120x1 (item 7011, also called Hercules). This IC has the following functions: Analogue Video Processing Sound Demodulation Audio Interfaces and switching Volume and tone control for loudspeakers Reflection and delay for loudspeaker channels Micro Controller Data Capture Display The Hercules has one input for the internal CVBS signal and a video switch with 3 external CVBS inputs and a CVBS output. All CVBS inputs can be used as Y-input for Y/C signals. However, only 2 Y/C sources can be selected because the circuit has 2 chroma inputs. It is possible to add an additional CVBS(Y)/C input (CVBS/YX and CX) when the YUV interface and the RGB/YPRPB input are not needed. One SCARTconnector is used (SCART1). This connector is fully equipped. The video part delivers the RGB signals to the Scaler IC. The Genesis GM5221 Scaler IC receives either the SDTV video input signals from the Hercules or the PC input signal from an external computer. Switching between the two signals is done via the SD/HD selection IC (7461). After the video processing done by the Scaler, the digital data is sent via a Low Voltage Differential Signalling bus to the LCD panel. LVDS is used to improve data speed and to reduce EMI significantly. There are two I2C lines and two interrupt and communication lines (TV_IRQ and TV_SC_COM) for the Scaler control. The Scaler communicates with the Hercules as a slave device. To avoid buffer overflow at the Scaler side, the TV_SC_COM line provides the necessary hardware flow control. To allow bidirectional communication, the Scaler can initiate a service interrupt-request to the Hercules via the TV_IRQ line. The Hercules, and EEPROM are supplied with 3.3 V, which is also present during STANDBY. The EEPROM, or NVM (Non Volatile Memory) is used to store the settings. The sound part is built up around the Hercules. The Source Selection, Decoding and Processing are all done by the Hercules. Power supply input are several DC voltages coming from a supply panel.

Power SupplyFor Service, this supply panel is a black box. When defect (this can be traced via the fault-finding tips, or by strange phenomena), a new panel must be ordered (see table below for ordering codes), and after receipt, the defective unit must be sent for repair.

CVBS and SVHS source select. It has also build in features like: CTI. Black stretch. Blue stretch. White stretch. Slow start up. Dynamic skin tone correction etc. Further, it also incorporates sound IF traps and filters, and requires only one crystal for all systems. 9.6.2 Inputs Analog RGB The RGB input is fed to pins 142, 143, 147, 148, 151 and 152. This input consists of either the Hercules RGB output or the RGB/YpbPr input of the VGA connector. The Scaler can switch between the two signals via the PC_HD_SEL signal and selection IC SM5301 (7461). PC DVI-D/-I/VGA input It depends on the model of the TV set, if a DVI-I or DVI-D connector is present. If a DVI to VGA adaptor is used, the analogue DVI input is processed by the VGA block of the Scaler. Digital signals coming from the DVI input are directly processed by the Scaler. The Scaler supports up to 1080i and UXGA 60Hz formats. 9.6.3 Output The Display Output Port provides data and control signals that permit the Scaler to connect to a variety of display devices using a TTL or LVDS interface. The output interface has four channel 6/8-bit LVDS transmitters and is configurable for single or dual wide LVDS. All display data and timing signals are synchronous with the DCLK output clock. The integrated LVDS transmitter is programmable to allow the data and control signals to be mapped into any sequence depending on the specified receiver format.

Figure 9-3 Block diagram audio processing The audio decoding is done entirely via the Hercules. The IF output from the Tuner is fed directly to either the Video-IF or the Sound-IF input depending on the type of concept chosen. There are mainly two types of decoder in the Hercules, an analogue decoder that decodes only Mono, regardless of any standards, and a digital decoder (or DEMDEC) that can decode both Mono as well as Stereo, again regardless of any standards. In this chassis, the analogue decoder is used in two cases: It is used for AM Sound demodulation in the Europe SECAM LL transmission. It is used for all FM demodulation in AV-Stereo sets. 9.7.1 Diversity The diversity for the Audio decoding can be broken up into two main concepts: The Quasi Split Sound concept used in Europe and some AP sets. The Inter Carrier concept, used in NAFTA and LATAM. The UOC-III family makes no difference any more between QSS- and Intercarrier IF, nearly all types are softwareswitchable between the two SAW-filter constructions. Simple data settings are required for the set to determine whether it is using the Inter Carrier or the QSS concept. These settings are done via the QSS and FMI bit found in SAM mode. Due to the diversity involved, the data for the 2 bits are being placed in the NVM location and it is required to write once during start-up. On top of that, it can be further broken down into various systems depending on the region. The systems or region chosen, will in turn affect the type of sound standard that is/are allowed to be decoded. For the case of Europe, the standard consists of BG/DK/I/ LL for a Multi-System set. There are also versions of Eastern Europe and Western Europe set and the standard for decoding will be BG/DK and I/DK respectively. FM Radio is a feature diversity for the Europe sets. The same version can have either FM Radio or not, independent of the system (e.g. sets with BG/DK/I/LL can have or not have FM radio). For the case of NAFTA and LATAM, there is only one transmission standard, which is the M standard. The diversity then will be based on whether it has a dBx noise reduction or a Non-dBx (no dBx noise reduction). For the case of AP, the standard consists of BG/DK/I/M for a Multi-System set. The diversity here will then depends on the region. AP China can have a Multi-System and I/DK version. For India, it might only be BG standard.
