I recently Bought an HDTV (LCD) and recently when I watch cable tv, the colours have gone all wierd (no blue)?
Answer:
If the 360 works fine, then it is either the cable, or the particular input you are using that has no blue. First try switching out the cable and using the same input to see if that fixes the problem. If not, it is the input. Not sure how easily repaired that is though.
What brand is it?
try unconnecting and reconnecting your cable,unplug everything connected to it then replug it.Also try your other connectors to see if they are all wired up correctly.Sounds like a wiring problem.I did the same thing to my projector once,I accidently thought the green was blue and I also accidently plugged in the R RGB into the composite video when I was rearranging things.lol
