Didn't know about the industrial monitors, they're built tough enough I'd say.

So the video input amplifier was a bust, everything was built to the schematic including the 1N34 but the Magnavox isn't happy with the addition. The issue is it seems not enough of the chroma signal is passing thru and this is causing most of the color to wash out. The amplifier bandwidth seems to be good as I have tested it with a sweep signal and it rolls off only slightly just over 5.5 MHz. Colorburst is strong but the color itself is lost except in the saturated areas, 75% colorbars seem to have a lag to the leading edge and they bleed over into the next bar, I forget the technical name for this. Running the set with RF has good color.

I've tried uploading images with zero luck, the best I can do is a 50k image file and that doesn't show the needed details, if I can't get the server to accept them I will do a quick vid and post it on YouTube as words can't accurately describe the issues, honestly I need a fresh set of eyes and some ideas here and any help would be appreciated.

Thanks to all
Brett
