VA-156A/156P board
• S1 (Y SEL)
• S125 (R-Y SEL)
• S221 (B-Y SEL)
When the external signals (Y, R-Y, B-Y) are supplied to
CN3 on the VA board, set S1, S125 or S221 to unmarked
position respectively.
For normal operation, keep the factory-setting position.
These are factory-set to marked position as illustrated.
• S126 (TEST ON/OFF)
Use this switch to check the VA board adjustment. When
this switch and the BARS button on the MSU control
panel are both turned on, an internal color-bar signal can
be supplied to the input stage of VA board. Using this
signal, each circuit operation check is enabled.
Factory-setting is “OFF” (marked position).
• S1101 (SEQ4/SEQ3)
This switch selects the SEQ mode for a waveform
monitor. This is for an optional circuit. When set to “3”
(SEQ3), three waveforms of R, G and B are sequentially
output. When set to “4” (SEQ4), four waveforms of R,
G, B and Y are.
Factory-setting is “3” (SEQ3).
If you use the SEQ4 mode, please consult your service
representative.
