I've sent an inquiry about this model. I should have an answer for you soon.
The Samsung website isn't exactly confidence inspiring. I bought a LN52A580 from Best Buy a few days ago, and started to look for information about it.
Am I correct that this is a model that was produced exclusively for big chain stores?
What model is it really? If I go to Samsung.com, it's not in the product finder drop down. The 540 seems to have similar specs, but it's not the same. (for example my TV looks like it has two real skinny speakers running down the sides, it also has no nightlight, but the 540 does)
I'd like more info about this model, but not sure where to look.
Anyone have any info, please chime in, and it would be Great to hear from folks from Samsung and BestBuy
