5. List of Electric Adjustment Points (Adjustment Menu Screen)
:
Check and adjust the state of applicable parts during normal servicing.
Precautions taken before adjustment
• If a mono-scope signal oscillator is not available for the adjustment which requires mono-scope signals, use the picture signal produced
by playback of the test tape, TTV-06T (PAL 625 LINE) and TTV-N06T (NTSC 525 LINE) via VCR. Observe the color system of input
signal (VCR output signal).
• This manual uses the values measured with SHIBASOKU mono-scope and the screen sizes expressed in percentage as adjustment values
of screen size measured with a mono-scope (PAL • NTSC). The values read by other mono-scope should be converted into percentage to
give compatibility.
• This manual uses the values measured with LEADER LCG-404 (PAL / SECAM) and LCG-401 (NTSC) as simple adjustment values of
screen size measured with a pattern generator.
