32JW-73E 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.

32JW-73E • Use the channel up and down buttons to move between the options. • Use the volume control buttons to change the data. • To store the data, use the stand-by button on the remote control. • To exit the Service Mode, turn the receiver off using the mains switch.
32JW-73E Note that the receiver should be set to FULL MODE before carrying out any geometry adjustments. This can be achieved by pressing the widescreen mode button on the remote control until FULL MODE appears on the OSD. This can only be done out of the Service Mode. The following geometry adjustments can be carried out. Detailed instructions on how to execute these are given on the following pages.
32JW-73E Corner Amplitude Adjust the Corner Amplitude so that the picture is centred. The effect of this adjustment is shown in figure 6. Note: This adjustment affects to upper and lower sides. • 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. • Press the stand-by button on the remote control to store.
32JW-73E S Correction Adjust the S Correction so that the picture symmetrical between the top, centre and bottom. The effect of this adjustment is shown in figure 12. • When the volume up button is pressed, the top and bottom scanning increases and the centre scanning decreases. • When the volume down button is pressed the top and bottom scanning decreases and the centre scanning increases. • Press the stand-by button on the remote control to store.
32JW-73E 3.3 Operate in Service Mode and select location GREEN GAIN and BLUE GAIN, to obtain colour coordinates: X=0.290 ± 0.015 Y=0.300 ± 0.015 To increase press volume-up button and to decrease press volume down button. GREEN GAIN alter «Y» coordinate. BLUE GAIN alter «X» and «Y» coordinate. 3.4 Exit Service Mode and check colour coordinates «X» and «Y» at 3 and 100 NITS. It may be necessary to repeat procedure 2 and 3 of Colour Adjustments. R-G-B Cut Off and Gain Adjustments (alternative method).
32JW-73E DVCO Adjustment (PAL) Carry out the DVCO Adjustment (PAL) as shown below: 1. Receive a Philips pattern signal. 2. While in the DVCO ADJUSTMENT (PAL) menu, press the stand-by button. 3. The adjustment will be carried out automatically and stored. DVCO Adjustment (NTSC) No adjustment required. AGC Adjustment (B/G) To correctly align the “B/G” Automatic Gain Control, follow the procedure outlined below: 1. Tune the set into a pattern generator on CH E12 (B/G). 2.
