Is the signal applied to pins (21), (22), (24), (25), (27), (28), (30)
and (31) of IC10413?
Because this signal is a high-frequency signal (about 1GHz), take
great care in checking it.
In the case of TV, video and component system
In the case of PC system
Note: The Ref.
No. of the PC I/F unit is REF.1XXXX.
Are the R, G, B, BOX signals outputted to pins (42), (41), (40) and (39) of IC1602,
respectively?
Are the R, G, B signals inputted to pins (57), (53) and (55) of IC1401, respectively?
