A-PDF MERGER DEMO Alignments Note: The Service Default Mode (SDM) and Service Alignment Mode (SAM) are described in chapter 5. Menu navigation is done with the 'CURSOR UP, DOWN, LEFT or RIGHT' keys of the remote control transmitter. General Alignment Conditions Perform all electrical adjustments under the following conditions: A C voltage and frequency: 110 V ( 0 %), 60 Hz ( %). 1 5 C onnect the set to the AC power via an isolation transformer. A llow the set to warm up for approximately 20 minutes. M easure the voltages and waveforms in relation to chassis ground (with the exception of the voltages on the primary side of the power supply). Never use the cooling fins / plates as ground. est probe: Ri > 10 M; Ci < 2.5 pF. T se an isolated trimmer / screwdriver to perform the alignments. U Hardware Alignments Created with novaPDF Printer (www.novaPDF.com) Fig. 1 Vg2 Adjustment 1. 2. 3. 4. Activate the SAM. Go to the WHITE TONE sub menu. Set the values of NORMAL RED, GREEN and BLUE to 40. Go, via the MENU key, to the normal user menu and set - CONTRAST to zero. - BRIGHTNESS to minimum (OSD just visible in a dark room). Return to the SAM via the MENU key. Connect the RF output of a pattern generator to the antenna input. Test pattern is a 'black' picture (blank screen on CRT without any OSD info). Set the channel of the oscilloscope to 50 V/div and the time base to 0.2 ms (external triggering on the vertical pulse). Ground the scope at the CRT panel and connect a 10:1 probe to one of the cathodes of the picture tube socket (see diagram B). 5. 6. 7. 8. Created with novaPDF Printer (www.novaPDF.com) 9. Measure the cut off pulse during first full line after the frame blanking (see Fig. 2). You will see two pulses, one being the cut off pulse and the other being the white drive pulse. Choose the one with the lowest value, this is the cut off pulse. 10. Select the cathode with the highest VDC value for the alignment. Adjust the Vcutoff of this gun with the SCREEN potentiometer (see Fig. 1) on the LOT to the correct value (see table below). 11. Restore BRIGHTNESS and CONTRAST to normal (= 31). Fig. 2 Focusing 1. Tune the set to a circle or crosshatch test pattern (use an external video pattern generator). 2. Choose picture mode NATURAL (or MOVIES) with the 'SMART PICTURE' button on the remote control transmitter. 3. Adjust the FOCUS potentiometer (see Fig. 1) until the vertical lines at 2/3 from east and west, at the height of the centerline, are of minimum width without visible haze. Software Alignments And Settings Enter the Service Alignment Mode (see Service Modes, Error Codes and Faultfinding). The SAM menu will now appear on the screen.
