Why would Ortho (with Overviews) fail to draw at larger scales?

I'm using ArcGIS 10.4, and have created a mosaic of about 190 TIFF images.  The settings I used are simply building a mosaic, pyramids set to -1, Update Overviews selected, Calculate Statistics turned on, and no compression.


The image extents will fit on one screen at about 1:80,000 scale.  The final output looks great, and the resolution is sharp.  However, when I zoom the scale in past 1:5,000, the image then fails to draw, and I get a screen filled with that dreaded checker board pattern.  When I zoom back out the image returns once I pass that 1:5,000 scale threshold.


I have not seen any question like this anywhere online, so I thought I would once again turn to the brains here to see what they think.  Would anyone out there know what is causing this, and how it can be rectified, or prevented in the future?  I do not have scale range turned on, and all of the symbology is simply using the default settings.  In fact, I have experimented with various stretch settings under the Symbology tab and none have any affect.
