I can tell you 1st hand...as I own the 40 version. About 8 months ago we experience a power surge. The screen had a sorta green tinge, then it cleared up. Ever since then, every time I went to connect to Netflix, it would take perhaps 5-6 tries before it would take. Then, I noticed after every firmware update, (maybe a span of 3 total) I couldn't automatically log into Netflix, meaning each and every stinking time I'm had to put in my name and password. I also noticed that at the bottom of smart hub, I used to be logged in all the time there as well. I realized that when I entered my name and password there, and ck'd the box to remember, that as soon as I turned off the set, it would not automatically log on.
Ok heres the deal with firmware updates. Since we have a year complete warranty, Samsung...after me bitching and complaining for nearly 3 months sent out a repair company. They told me...."DO NOT UPDATE THE FIRMWARE". They said they had seen firmware updates ruin the main chip on the main board, to where there was no fix other than replacing the motherboard, which they did. It is now working like brand new, with the firmware being about 1 year old. They said there is no reason to update the firmware.
I also (after the repair) called Samsung to update my file. I asked that they retrieve my old motherboard, which is "usually" their policy and per my complaints...(netflix not automatically connecting, smarthub not remembing my name/password and auto connecting, the number of times in which Netflix takes to connect to a show and a grinding/buzz intermitent sound now and again in the set) and disect into the board to figure out what the hell had happed. I also told them what the repair company had told me about the firmware issue. Samsung agreed, that updates should not ruin the hardware. I mean good grief, there are even warnings stating, "take this upate may void your warranty". Why the HELL would they even allow this?
Anyway, this was my experience. I suggest you get a very good voltage/surge suppresion system, including the antenna, and NOT take anymore firmware updates. Just because they are there and available, does not mean it will make your tv work and better.
Please share this info along with other...
