7 Troubleshooting 7-1-4 S Correction Failure Check S1 ~ S5 signal. Are the S1~S5 signals at each frequency block correct? Yes Check and replace Q408~Q412, Q414, C434, C435, C436, C437 and C438. 7-1-5 H_Lin. Failure Does the IC201 Pin 4 voltage vary with different H_Lin. DAC values? Yes Does the IC402 Pin 4 voltage vary with different H_Lin. DAC values? Yes Check L406. 7-1-6 Invariable H_Size Does the IC403 Pin 28 voltage vary with different H_Size DAC values? Yes Does the IC401 Pin 6 output duty vary with different H_Size DAC values? No No No No No Check and replace IC201. Replace IC201. Check +12 V, –14 V line and some parts around IC402. Check and replace IC403. Check some parts around IC401 and IC403 Pin 28. 7-4 SyncMaster 1000s (CGP1607L)
7-1-7 Abnormal H_Size 14 Does the IC201 Pin 5 output duty vary with different B+ offset DAC values? Yes Does the T402 Pin 8 waveform match #14? Yes Check some parts around D408. 7-1-8 Side Pin or Trap Failure 16 Does the IC403 Pin 24 output match #16? Yes Check and replace IC401. Check some parts IC401 Pin 2 and IC403 Pin 24. 7-1-9 Para. or Pin Balance Failure Does the IC403 Pin 5 output vary with different DAC values? Yes Done. No No No No Check and replace IC201, some parts IC201 Pin 5, IC403 Pin 28 and IC401 Pin 2. Check and replace T402. Check and replace IC403. Replace IC403. 7 Troubleshooting WAVEFORMS 14 3.32 V (IC403, #12) CH1 P-P = 3.32 V CH1 RMS = 0.83 V WAVEFORMS 16 1.64 V (IC403, #24) CH1 P-P = 1.64 V CH1 RMS = 3 V SyncMaster 1000s (CGP1607L) 7-5
