I have a 2001 - 2002 Samsung HDTV 53" Rear Projection TV. I noticed when doing the 64point covergance this weekend that my blue color has faded to almost non-existance. If you removed red and green, just leaving the blue its very faint, and you can not see the four corners or the very top of the screen. Is this a mechanical adjustment? or is it something I can adjust via the service menu? Does anyone know of a good online resource for samsung TV, tips tricks, service menu recommendations? Thanks in advance.
