If we see an error in the pixel, we basically duplicate the previous good pixel so in effect what the customer will see is that
the pixel is delayed by 1 when the pixel is bad/gone. But in reality a bad pixel will be replaced by a previous good pixel value. For HS/VS defects the HTRACKEN/VTRACKEN will fix for glitches (As it detects a periodic sync signal and will fill in the gaps for the glitches)…. However if the HS/VS glitches or losses are too severe such as 3~ consecutive misses then the HTRACKING and VTRACKING will lose tracking.
