7 Troubleshooting 7-2-3 Missing Color Are proper Video levels on CN D-sub pins 1, 2 and 3, CNR, CNG and CNB. Yes Are proper AC voltage present on all cathodes? Yes Are proper DC voltage present on all cathodes? Change the CRT. Done Yes Is the G2 voltage correct? Yes No No No No Check signal generator and cable. Refer to 7-1-16 No Video. Check IC107 Pins 10, 11 and 12, IC104 Pins 24, 25 and 26. Check QR104, QR105, QG104, QG105, QB104 and QB105. Check G2 wire, control G2 volume of FBT. 7-16 SyncMaster 1000s (CGP1607L)
7-2-4 Visible Retrace 34 35 Check white balance adjustment. Is the G2 voltage correct? Yes Is blank pulse present on Pin 27 of IC104 on Video Board? Yes Is blank pedestal present on Pins 29, 32 and 35 of IC104? Yes Is G1 pulse present on Pin 6 of CN102_B? Done Yes Is blank pedestal present on all cathodes? Yes No No No No No Check G2 control volume and FBT. Check Q108, CN101 Pin 1, T402 Pin 8. Check IC104 and related components. Check Q106 and CN101 Pin 27. Check IC107 and Pins 24, 25, 26 of IC104. Check QR104, QR105, QG104, QG105, QB104, QB105. 7 Troubleshooting WAVEFORMS 34 5.56 V (IC104, H_BLK) CH1 P-P = 5.56 V CH1 RMS = 1.990 V 35 3.60 V (IC104, #35) CH1 P-P = 3.60 V CH1 RMS = 2.938 V SyncMaster 1000s (CGP1607L) 7-17
