I have a Scientific Atlanta cable box w/ Time Warner. I followed the instructions below for the cable box. Somehow it reset my picture and I can now read the ticker at the bottom of the screen and the different picture sizes seem to work properly. Good Luck.

I would take that puppy back to store and get exchanged out. According to lemon law. Let me know what happens. Thank you Jay.

TRY A DVD PLAYER TO VERIFY IF IT COULD BE THE SAT.BOX OR MAYBE TV COLOR ADJUSTMENTS.JOE TV

Are you connected to a cable box or satalite rcvr using compoment outputs (y,pr,pb)? It is posible that the red cable has come loose and picture has no red,causing a mostly blue picture.

If you are using a HD cable box or satelite with component outputs, be sure that all 3 cables ( green, red, and blue ) are making good connection.A loss of red or blue will cause color shift. Usually,if the tv menu comes up as the correct color but the picture dose'nt, it is most likely a signal problem.
