F116 should be a 3 amp slow blow
I would suggest first disconnecting the LCD then see if the fuse blows in attract mode.
If it doesn't' then try doing the same with the color DMd.

You will either find that one of them is " breaking the camels back" so to speak by over loading the unregulated 12 volt circuit or one of the items have a fault

I know that the color DMd manufacture suggests that you plug it into the unregulated 12v line and do not suggest running it off anything else.

There are no specs on how many milliamps the color DMD draws in paper work supplied with the DMD but if need be I can do a test on the one I have here.
