(Check the V frequency with the
QSI command.)
Is the sync signal properly output
from the MAIN Assy?
Disconnect and reconnect the
50P (J212) FFC/40P (J211) FFC.
• If the OSD is not properly displayed although the panel mask is properly displayed,
a failure exists in the path from the output of IC2801 on the MAIN Assy to IC3301 on the DIGITAL Assy.
-> If only the OSD is abnormal, the MAIN Assy is in failure.
• If no vertical sync signal is input to the DIGITAL Assy,
a freeze-frame picture will be displayed.
