Also, there is no OSD. CAUSE: The channel data transmission between IC7706 and IC7704 (serial clock & serial data) is corrupted (permanently keeping the signal HIGH), but data transmission of the OSD microprocessor and system microprocessor are correct (for FIP display). Therefore, the result being that the FIP display works properly but the tuner data does not, resulting in an error. REMEDY: Please add the oscillation circuit to prevent the noise effect on IC7708.
