An out of adjustment set could do this. Some TVs suffer in shipping or "dropped" too hard and you seem to have a defect OR you have an external speaker too close.
I just bought the Toshiba 30hf83. I am very disappointed in the color on this set. Everything on the screen to the right and left of the picture turn this purple tint. It happens with the cable box, DVDs, S-cables, Coaxial, Component cables. I have spent hours fooling around with the color settings but nothing seems to get rid of this purple tint. I turned off flesh tone and a lot of settings like see on other messages but this only seems to help a little.
This is so bad that if I watch CNN, for example, they scroll yellow text along the bottom of the screen. But on this tv it is yellow only in the middle 3 inches of the screen, the outer sides turn purple.
Should I keep fooling around with the color settings, or is this a sign something may be wrong with the tv? I had ordered this from amazon.com and I am waiting to see what they will do about this, though their website says that they do not take tvs of this size back. Any help would be appreciated!!!!
