I have a Samsung HL-T61768 TV that has an issue With white dots on the screen. It started as one dot and has become about40 dots. I called the Samsung "service" center and they told me that the issue is not covered. I did some research online, and it lookslijethe cost is more than buying a new non-Samsung set. Has anyone fixed the problem on their own or have reliable service company inAtlanta? My reference # is 2109496078. Any help would be appreciated as fixing it using a repair service is cost prohibitive.
