Question: why my Samsung bn5901134b remote control wont pair with the tv
Document: I've had my Samsung UN46 model tv for about 5 months and in that time I have had to replace the battery for the remote at least 4 times since then.4 times!!!!!!!!!! The first time I thought it was no big deal, they were the crappy factory batteries that were included. Then I got really scared one day when my tv would not turn on at all. I thought maybe the sensor on the tv was bad or it somehow shorted out.
Do not by this remote. The battery life is very back. I had to replace 6 AAA batteries every other week. The batteries were actually leaking every time I took them out. Eventually the remote stopped working. I did lot of research and eventually found this Samsung Universal remote for LED TVs.Buy insteadSamsung Universal Remote Control 3DTVs
The bluetooth side still works fine - too bad I can't control ANY of my TV's functions with it.A replacement would put me out $120? Don't get me wrong, I've loved all of my Samsung TV's, but this product was obviously rushed to market before it was fully developed, and the customer shouldn't be held responsible for this kind of negligence.
The remote control is a hazard! I went to use it and and found that the batteries were fried, so I purchased a new battery tray and it fried the batteries again and burnt the new tray!! I have never had a remote that fry's batteries. This is extremely dangerous! Could injure your hands or start a fire! Samsung won't stand behind their products! Consider yourself warned! (Amazon makes me give a star rating, but they don't even deserve one star!)
I had the dreaded leaking battery syndrome for the third time with the OE BN59 remote..the third set killed it. No choice but to order another one that I just received and all is good. I think DO NOT STORE this remote with batteries in it, is the only way. The remote from the BD player would not access all the menues on the unit.. When it works it is great...when it doesn't not fun to use 8000 series tv
I also synced my phone and tablet to the tv so I can use them as remotes. It works great with one terrible exception. My phone and tablet only function as a remote when the Tv is on. They will adjust color, picture, sound, and any and all settings and even turn everything off, but you will be screwed if you try to turn the tv on with either of them.So now I try the absolute minimum to use this silly battery eating, money sucking, power hungry remote.
Just when I was about to give up hope and feared the worst, I decided to change the batteries on the remote. Poof! The tv turned on instantly. And it was then I knew that the remote was the problem. I then took steps to minimize remote usage. I never ever surf the web or use the Internet apps on the tv. I didn't care what anyone says, a mouse or trackball runs circles around anything else for web browsing.
So far so good. Hopefully It wont start blowing up batteries, Like my original one did. my first one was a -  A model.
To add my star to the pile of discontent, this remote has been nothing but a pain. Not only does the bluetooth-paired qwerty keyboard have unusable input lag, but it's not actually compatible with ANY of Samsung's SmartHub apps, not even most of the native UI features. Furthermore, there's no way to control the standard functions of the TV through the bluetooth connection (power, volume, channel, source input, etc), so you need line of sight infrared for 99% of your interaction anyway.
Everyone has talked at length about this remote. I can't add more. Is this a ploy to sell some expensive remote to people? If it is, Samsung you suck!
Answer: Because this remote is total garbage and should be recalled ! Do not leave the batteries in this remote for any length of time, the batteries will overheat and leak inside the remote. When I called Samsung about purchasing a new remote for my smart TV because the batteries had leaked inside my remote they failed to mention that this has been an on going problem with this remote! I read the reviews on Amazon Everyone has same problem with batteries leaking !
