Summary: a lot of the apps seems to be unfinished. have not been able to use a keyboard on the internet function. some movie apps do not appear correctly. For me the plasma would be better if it was not a smart tv. None of my devices which are Samsung work well with the tv. my phone or tablet which are Samsung s4 and galaxie note tablet.
Summary: I am currently on my second set. The TV emits a buzzing sound from the front of the panel which can be heard at the back of my room. If you are watching the set and you are directly in front of the set, you will hear a distracting buzzing/clicking sound. This can only be heard directly in front of the screen up to 20' away. If you are to the side of below, you won't hear it- unfortunately the best place to watch TV is in front of it.
Summary: The product photo for these TVs (the 550 series) shows a matte, anti-reflective screen. This is misleading. The 550 series does NOT feature an anti-reflective screen. It has no anti-reflective coating at all. It is as reflective as glass, and consequently not the best choice for rooms with windows. Amazon's product description for the 550 series is identical to its description for the next model up (the 6500 series).
Nice set, great features, lots of tweaking options. Problems with fade to black movies, random auto brightness and slight buzz

Summary: **Have only had the set for 4 days, still tweaking settings** The I purchased this set after returning an LG LED 47 inch Cinema 3D set, the problem I had with the LG set was the sports and HD in general looked really washed out and messy; after several days of tweaking the settings nothing seemed to help. I then stopped researching LED's and jumped to researching new model Plasma's.
