28JF-76E IMPORTANT SERVICING NOTES Only qualified service personnel are allowed to carry out maintenance and repair of this receiver. Servicing of High Voltage System and CRT It is important that the static charge is removed from the high voltage system when carrying out work on the receiver. This can be achieved by connecting a 10K resistor (with a suitably insulated lead) from the CRT cavity connector to the CRT ground tag. This must be carried out with the AC supply disconnected from the receiver.

28JF-76E ADJUSTMENT PROCEDURES All adjustments to this chassis, except for focus and G2, are carried out in the Service Mode. • SERVICE MODE The Service Mode is provided to enable the engineer to correctly set up the receiver to the CRT fitted in the set. Note that the value of these adjustments may vary from one receiver to another. To enter the Service Mode, carry out the following procedure. 1. Connect a test pattern to the antenna terminal. 2. Tune the receiver to this signal. 3.
28JF-76E The following geometry adjustments can be carried out.
28JF-76E • When the volume down button is pressed, side pincushion changes from barrel shape to pincushion. • Press the stand-by button on the remote control to store. Upper corner correction Adjust the Upper Corner Correction so that the picture is centred. The effect of this adjustment is shown in Figure 7. • When the volume up button is pressed, side pincushion changes from pincushion to barrel shape. • When the volume down button is pressed, side pincushion changes from barrel shape to pincushion.
28JF-76E Vertical bow Adjust the Vertical bow so that the picture is centred. The effect of this adjustment is shown in Figure 12. • When the volume up button is pressed, the vertical bow changes to left. • When the volume down button is pressed, the vertical bow changes to right. • Press the stand-by button on the remote control to store. Figure 12 Vertical size Adjust the Vertical size so that 8% over-scan is achieved. The effect of this adjustment is shown in Figure 13.
28JF-76E Colour Adjustments The following adjustments should only be carried out when the CRT or IC850, IC851 and IC852 are replaced. Follow the procedure below to set the Cut Off. Do not change the Cut RED value (50%). 1. Adjust G2. 2. Tune a white pattern. 3. Adjust colour to minimum. 4. Position colorimeter in the centre of screen. 5. Adjust brightness and contrast to obtain a luminance of »20 NITS. 6.
28JF-76E 4. Press volume up/down to adjust to “109 dB/µV”. 5. It will be stored automatically. 6. Turn off the receiver by Main switch to exit the Service Mode. Automatic Gain Control Adjustment (L) To correctly align the Automatic Gain Control, follow the procedure outlined below: 1. Tune the set into a pattern generator on F-10. 2. Enter the Service Mode. 3. Press the YELLOW button of Remote Control to select “Automatic Gain Control” 4. Press volume up/down to adjust to “103 dB/µV”. 5.
28JF-76E Flag NVM write ON/OFF To use this function to rewrite the NVM. It is only necessary when the software of Flash memory (IC6003) change . 1. Enter the Service Mode. 2. Press the Sound mode button(29) of Remote Control. “FLAG NVM WRITE ON” is activated. 3. To exit the Service Mode, press the volume down and channel up buttons on the front of the receiver at the same time. 4. When “RE-WRITING NVM” appears on the screen, the receiver is now rewriting datas in NVM memory. 5.
28JF-76E LED FLASHING CODES This model is not provided with stereo led, so to let “flashing codes” for IC failures detection when the TV set does not work, we offer the next solution: • The detection of failure will be made with an external LED. • The output of the flashing code will be via AV1 (pin 10). • Insert a generic led diode between pin 10 and ground (i.e. pin 5) as shows the below picture.
