Not a pal unit, if so I would get no video at all on the tv correct?
The Unit outputs fine on channel 4, and the green boot color looks fine, but the blue artifact color is screwed up.
Red looks red, blue is green.
Also the wiki says
"Users in PAL countries saw green and purple stripes instead of solid red and blue colors."
That's not my symptoms.

Open it up and see if it is a PAL unit. I seem to remember that the artifact
colors on PAL units do this.
You could adjust the tint control on your TV. That might get you the required
