2-14 WFM700 Series Waveform Monitors Service Manual
This step checks for defective display pixels with a HD video signal.
Performance Requirement. This test verifies performance characteristics and is
listed in the test record.
1. Connect the HD video generator to INPUT A using a 75 8cable.
2. Set the HD video generator for a 1080i 59.94 100% flat field signal.
3. Press the INPUT button and select Input A.
4. Press the PICTURE button.
5. Count any pixels stuck low (not white).
6. Change the HD video generator signal to 0% flat field.
7. Count any pixels stuck high (not black).
8. CHECK the total number of pixels counted in steps 5 and 7 is less than six.
NOTE. If the bad pixel count exceeds six, perform the procedure again. If a pixel
fails for both black and white signals, count it only once.
