After much (at least one year) research and checking out the CU ratings, I sprang for the 63" B590. Pushing my beloved, 3 1/2 year old Sony 60" SXRD to the side. See more on the Sony SXRD below...
Mostly lovin' the Sammy. Got it a a sweet price. Set it up without needing the owners manual. Best TV I've ever seen! No burn-in procedure was followed except to keep it on full screen for a couple of weeks. No IR issues. No buzzing.
There is a small issue. The reds are noticeably tinged with yellow as well as the overall "look" of the panel. Adjusting the offset, gain and gamma hasn't helped. Contacted Magnolia (Best Buy) and they are sending a certified tech out on Saturday to hopefully, straighten things out.
I'll post corrections when I get them.
BTW the way, I contacted Samsung before calling Magnolia. Samsung sent out a local TV "expert" that promptly told me that "color" was a "personal choice" and he saw nothing wrong with my panel...LOOKED FINE TO HIM!!! Further, he refused my request for the access code to get into the sub-menus. The tech was here no more than 10 minutes. Great!
The Sony SXRD light engine lasted for 3 years. Still on the original lamp. When the light engine went bad (green) Sony sent out a technician that replaced the engine, No Charge and No BS!
