hi guys, PN51E550 owner here. its my first samsung and my first plasma. i have it for a few month not bothering setting up anything but i did make sure that i follow the break in guidelines.

i have a few questions though regarding our TV, is the lag normal? i dont see people complaining about it but its actually the reason why i didnt bother tinkering the smartmenu because it lags so much.

another thing does anyone experience loosing control either with the remote controller or the panel controller? this usually happens when i thinker alot with smart menu while something is updating/connection/loading or when im impatient and press smart menu then press tools and press something else that requires it to load. i tried waiting but even after an hour my remote control still doesn't work, even the panel control on the tv wouldnt work. i have to unplug it to make it work again.
another recent encounter i had when i started using social tv (
which was just yesterday) when i turn on the tv it restart several times before it could actually run smoothly. sometimes on the process i even end up loosing control where tv wont respond using the remote nor the panel and again i end up unplugging it tv to make it work properly again.
my problem really is when my daughter uses the tv, shes just 4 and wont be able to do what i can do to make the tv run properly. the smart feature for me at this point is just so unreliable that i would rather turn all features off so it doesnt cost problems.
hope someone can shed some light that way i know if all those things iv experienced are normal or those my tv needs some servicing/replacement.
