Procedure: 1. Connect the oscilloscope to BP11 (TE) and TP (VC) on the RF board. 2. Put the set into play mode by loading the disc. 3. Press the = AMS + button, and check the traverse waveform*.
IC51
Procedure: 1. Connect the oscilloscope to TP (RF) and TP (VC) on the RF board. 2. Put the set into play mode by loading the disc. 3. Confirm that oscilloscope waveform is clear and check RF signal level is correct or not.
Note: Clear RF signal waveform means that the shape ��� can be clearly distinguished at the center of the waveform.
4. Confirm that the oscilloscope waveform is symmetrical on the top and bottom in relation to 0 V dc, and check this level.
* Traverse waveform: This is the tracking error wave form appears when crossing the track.
