It’s the same problem as described here:

VGA red input lost

Dreamcast – blue image

VGA input seems to have lost red

Dreamcast blue screen VGA

Seems like some older(???) vga-boxes for the Dreamcast can do some damage on the A/D converter IC (TVP7002 = U1). The broken TVP7002 needs to be replaced in order to have a fully working OSSC again.

Could you please tell us which vga-box/-cable you’ve used for connecting your Dreamcast to the OSSC? This information may be helpful in doing some research regarding this issue (since it seem to affect only a small group of Dreamcast owners and it’s not exactly clear yet, which combination of DC + cable/box could cause it and why).
