Hey I having trouble with my dchdmi there are a bit of artefacts and there is a green tinge to the graphics. When I run the test info 00 and 01 have x's under them. Wondering if anyone has any knowledge about any of this?

you'll need to check the soldering on the video chip.

http://dansprojects.com/dchdmi_install.html is the official install guide but there's an image in it https://imgur.com/twrlHpU that shows you which pins relate to the selftest. essentially, all the numbered pins on the left chip directly relate to the selftest so if pins 00 an 01 have X's then those are the ones you need to check the connection on (D0 and D1 on the pic)

So basically those two have become disconnected? Is there anything very serious that could be broken or is it just some solder?

Most likely a bad solder job by the sounds of it. Go over the flat cable & ensure you have good solder connections & also check for any bridges.
