Locked SmartTV UE40EH5300

[troyerr]

How can I locked my Samsung SmartTV ue40eh5300? I may disable(locked) channels, but I don't want this function. I need locked TV and If I TV turn on then I'll need enter a password then I'll watch TV. Have you any information how can I do it? Thx.
Next question:
I can't enable PVR and PIP in this SmartTV. If I get to the service menu I don't see section PVR or PIP. Where is it? I did it PVR as instructed: viewtopic.php?t=5276

something like this: viewtopic.php?f=5&t=8337 ?
When you at home, you plug USB with your "password" on it and TV will operate normally. When you not at home, take usb with you (or keep in safe place) and tv will shutdown = inpossible to watch normally.

Maybe it would work but it's not what I'm looking. I need to modify the script to the E series and I will not to know this. I need something like this: I turn on TV and show pin or password If I insert correct password I will watch TV, If I insert wrong password I wouldn't watch TV. Do you understand me?

[juusso]

Sure i do. No solution ATM.

[troyerr]

Is there any other solution "to parental controls"?

[juusso]

No. But i wish we had it exact like you described.

What a pity.
My second question:
I bought HD receiver where I may record on USB, but... but I want enable PIP if it possible on my TV. I'm in the hotel menu but I don't see nowhere PIP section or enable PIP. PVR doesn't work according to the instructions (see above).
