Using a samsung smart remote with a sky+hd box

[martomart]

I have a Samsung S95B tv and use the included samsung smart remote to control my external devices such as my Nvidia shield however my sky+hd (not sky Q) box does work but only when i'm very close to it and the strangest part of all is it doesn't matter where i point the remote which would suggest it doesn't need line of sight but if i close the cupboard the box is in it stops working even at the range it was working at before. This is really baffling me because the remote has full functionality up close but doesn't work at all when more than 0.8m ish away despite working fine with all the other devices. Any help appreciated

@martomart Sky+ remotes work only on line of sight, but the signal can be reflected easily, so can be received even if you don't point the remote directly at the box. 

If the Sky remote doesn't have the same limited range, it suggests that the Samsung has a lower power output at the waveband used by the Sky box.

I understand what you're saying but i can't see how this would be the case, if i am near the box/tv pointing the remote away then the ir waves would have to travel the length of the room and back which is a greater distance yet it still works? i'm rather confused

IR is just non-visible light. It can bounce and scatter unpredictably.

I have done some investigating and I have figured out that the IR on the remote works fine until the smart TV turns on at which point it stops (checked with a camera) which is very annoying and more than likely something Samsung related

Odd. I can't imagine why it would do that - intentionally anyway. Perhaps try the Samsung forum, assuming they have one?

yeah  the only thing i can guess is to reduce power consumption since the tv only uses IR to turn on? Either way thanks for the help
