Autostretch not displaying properly



I am having a weird little issue that when i take any shots for framing or such, the autostretch , even when it is set to low, displays a blown out image. It is often extremely bright and the histogram is just too narrow that i have to move the sliders out to reveal details in the picture. I am sure there is a short between the keyboard and the chair on this one.

I am using an Atik 383L+, moonlite focuser, ES127ED

Thanks for your time.
