I think you meant to say this:
"My K20D shows red splotches where white should be, when previewing photos."

You have the camera set to show areas that are blown out in red, to highlight the fact that certain areas are overexposed. Turn it off if you like. Or use it to decide when you need to turn down the exposure compensation.

check your white balance settings. If I set mine to indoor/bulb/tungsten and shoot outside I get very blue images. You may have the WB set to something like sunny and taking pictures indoors?
