Slanted/skewed picture on Predicta Holiday
#2

Hi C Storm,

This is called "tearing" and may be caused by an issue with either the sync separator or because the signal is too strong. Try to "attenuate" the signal from the modulator. Turn the fine tuner from lock to lock. Does the picture stop tearing when it gets "snowy? In addition, test the DVD / Modulator "rig" with another analog TV. If tearing occurs on the other TV, then the issue is with your modulator. If the modulator is good, then troubleshoot the sync circuit. Good luck.
