Thank you everyone. I found out what the problem was. One of the
blades on the shutter came off track and was blocking the sensor from
functioning. So the guy fixed it and also hand cleaned the sensor.
Camera OK now. It was not the sensors. Cost $60 bucks to clean sensor
and fix blade (gave me a 20% discount) Thank goodness it wasn't the
IF the filters in Bayer masks created three discrete color ranges in which any particular wavelength could only pass through a single filter, then the resolution would be 1/2 for the "green" filtered wavelengths and 1/4 for the "blue" and "red" filtered wavelengths.

I saw multiple posts online which said it's reduced by 1 / sqrt(2), but they offered no explanation of why this is the case.
This one is easy to explain. The typical Bayer tile has two identical green-filtered photosites and one instance of each of red- and blue-filtered photosites. The green-filtered ones are usually on the diagonal.
Suppose the ...
There is no reduction in "true resolution." It is optimally 1 point per pixel (photosite), 1 line per pixel row/column, or 1 line pair per two pixel rows/columns (nyquist).
Although it seldom is in practice due to the lens, AA filters, etc..
Photosites do not record only one color. They are filtered to short wavelengths (blue), medium wavelengths (green), ...
