KD-VP1250/750 Troubleshooting
If you use component output from KD-VP1250/750 and don’t see any picture, try the
following:
1. Set output resolution to 480i or 480p (European customers should set it to 576i or 576p) by
pressing ‘Output Resolution’ button on the front of the unit.. Keep in mind that if LED doesn’t
change after pressing ‘Output Resolution’ button, frame rate changed to 50hz with the
resolution remaining same.

Output Resolution Button
2. If you still don’t see any picture after changing resolution, press R1 button on the remote to
change analog output mode to YPbPr. This is required because if the KD-VP1250/750 is set
to RGBHV output, component sync is not available on the output, resulting in the display not
showing any picture.
