Question: Will it turn off the tv permanently until I want to turn it on?  I have a child who gets up in the night and watches Tv.
Document: I'd like to term the tv-b-gone as "the world's most powerful keychain". No other universal remote comes close in speed and power. As a result, I have grown very fond of it.Despite its strengths, it has its weaknesses as well. I can only turn TVs on and off using it, but with my other remotes I can change the volume, channel, mode, etc. After a while the tv-b-gone gets boring for pranking.
About half the time this doesn't actually do anything, the other half of the time it takes what feels like forever and sometimes multiple attempts to properly aim at the TV you want to turn on/off.
Keep your arms down at your sides, it has a fairly good range.Going into stores that have large displays of television sets, it is fun to hit the button and watch the sets go off. Some go off quickly, others take a while as the unit gets to that specific brand. Some sets can take quite a while to turn off.Sony must be the very first code in this unit, as Sony sets go off imediately.
This worked on my tv really well but when others tvs were running and they were not in their rooms welllol such is life. I would (( as stated ) not turn off their tvs.
I got this for Christmas and it wouldn't even turn off my own tv. I went to the web site (tvbegone.com) and they do not offer refunds. I think tvbegone uses a lot of hype and poor business practices.
I've had my tv-b-gone gen 3 for about 4 years now and I have enjoyed myself tremendously with it. I own many other universal remote controls but this one is the most idiot-proof one available. Simply point and shoot!I appreciate the speed at which TVs go off but however, some common brands like LG take a longer time to turn off. In addition, it totally doesn't work on many lesser-known brands.
If you want to get one of these, do not get one of the colored transparent ones. They have a bright blue light that flashes when it is working. I do not believe that the black ones have this.
My husband likes it, but found out he has to be fairly close to the tv he wishes to turn off.
Works as advertised...but unfortunate that infrared doesn't work through glass...would be great to turn off the tv from outside the house.
Very poor range, not worth the shipping cost  Have tried at work to fool coworkers in break room, setting 5 foot from tv and nothing happend when trying to turn the set off. Tried at home and worked twice out of four attempts. Would not recommend
Answer: Nope! It only turns the TV off as if you were using a regular remote control unit. It will not disable the TV from being turned back on again manually. When my kids were younger we had the same problem. I installed a common mechanical timer to the TV power supply then hid the unit behind the set with a bunch of other cable boxs etc.
