1. Input the 480P color bar pattern to the INPUT B terminal.
2. Set the ASPECT to 16:9 in the MENU screen.
3. Set the CHROMA and PHASE VR on the front panel to the click position.
4. Turn the COMB SW to the "S" side.
5. Connect the oscillo-scope to the TP-47R and TP-47B.
6. While observing the waveform of TP-47R, adjust the SD04 to obtain the straight waveform between 1 and 2, 3 and 4 (Fig.1 ).
7. And then while observing the waveform of the TP-47R, adjust the SD03 to obtain the straight waveform between 1 and2, 3 and 4 (Fig.2).
8. While observing the waveform of the TP-47B, adjust the SD09 to obtain the straight waveform all of 1 to 4 (Fig.3).
9. Confirm that the waveform of 1 to 4 are straight. If illeagal, readjust the step 6 to 8 as same steps.
10. Turn the COMB SW to "N" side, and confirm the chroma/phase condotion not unusual.
