The original service center that I was assigned to was too lazy to set up an appointment and come out and look at my set, so he basically diagnosed it as being the color wheel (incorrectly of course) simply by talking to me for about 1-2 minutes on the phone. He asked me to describe the symptoms, what I saw/heard etc. I did and he said "that's your color wheel without a doubt." He said he would just order the color wheel and then set up an appointment to put it in. First it took me 3+ weeks to even get in touch with that guy and have him attempt to set up an appointment to come out and install the color wheel (which as I know now wouldn't have even fixed it) and I go so fed up with his lies and poor service that I called Samsung and demanded another service center. They told the second service center that it was the color wheel (misdiagnosed by the first center) so I had to wait 2 weeks for THEM to get one in stock, then 2 weeks for them to come out and tell me it wasn't the part I needed.
Just overall poor communication and professionalism as a whole from the start. Anyway today is Saturday... 2 more days until me next appointment. If on Monday afternoon I don't have a perfectly working TV I will be calling Samsung and demanding a new TV.
