Query: I got a lemon!

I bought this TV in February and have had a repair person come to my house 5 times already and they have yet to fix the problem. The TV does not show the color blue so the sky and everything that should be blue is green and anything that should be white is yellow. Last week they replaced the picture tube and it still did not fix the problem. My TV is getting new parts one at a time service call by service call and none of it have fixed the problem. Each new part has to be ordered and that always takes a few weeks. It is covered under the warranty but who cares because I have looked at a horrible picture for the last 6 months. I just want a new TV!
