A smart TV which you don't plug into the Internet, is the same as a dumb TV.
- debaserab2 10y agoNo it's not. Not when all basic TV functionality is handled through its operating system.
- mike-cardwell 10y agoI have a Sony Bravia Smart TV. The only thing I use on it is the screen, the power button, and the volume control. Everything else is handled by the Internet connected Amazon Fire TV stick I plug into it. It is effectively a dumb TV and will not get infected by malware.
- kfriede 10y agoUnless it can be infected using the stick as a proxy (though I haven't seen that as a possible vulnerability yet).
- TylerE 10y agoThat'd be quite the feat, at the only connectivity between the stick and TV is via HDMI.
- mciancia 10y agoEthernet over HDMI is a thing.
- wernercd 10y agoWell... considering Light Bulbs can now be infected over the air: http://boingboing.net/2016/11/09/a-lightbulb-worm-could-take-ov.html http://boingboing.net/2016/11/09/a-lightbulb-worm-could-take... I would agree odds are low of something that insidious... but it's hard to say "it'd be impossible for my TV to get hacked" when even light bulbs are getting attacked.

- debaserab2 10y agoI have an LG with WebOS and try to use my TV the same as you. I don't have it connected to wifi so it's unlikely that it will get infected with malware anytime soon, but it did crash yesterday when I turned it off at the end of the night. I had to pull out the power plug to turn it off. That's one thing that never happened to me with a (truly) dumb TV and I've only owned this one for a month. I sure hope the CPU hardware running this OS doesn't degrade as quickly as normal consumer PC hardware and I can expect it to run as quick and reliably as it does now in ten years from now (like the TV it replaced did).
- izacus 10y agoWell it isn't. First of all it's the obvious software deficiencies - it'll still boot a heavy OS (boot times can exceed a few minutes from col start), even operations like switching HDMI inputs take significantly longer. Also several manufacturers (I know of some Samsung versions and Phillips) will position web services in first-level UX navigation making those TVs annoying to use as dumb TVs. There are even some models that will constantly nag you to connect them to the internet!
- foobarian 10y agoYou know what I miss? When my CRT TV would turn on in 2s, and channel switches took < 100ms.
- StavrosK 10y agoThat was great, wasn't it? Channel switching was instant, why can't we have that now too? :/
- nitrogen 10y agoIt's probably because of the span between consecutive I-frames (or intra-block sweeps if not using I-frames) in the video stream, but audio should switch "instantaneously" (within 1 frame).
- StavrosK 10y agoHmm, if that were the case, wouldn't the time spent waiting be variable? That would mean that you'd sometimes get instant switches, when the I-frame was the next frame you received after the switch.
- tinus_hn 10y agoIt is variable, the stations are multiplexed on channels, so sometimes you can use the same stream and sometimes you have to switch. That takes time. I presume the TV hides that by always taking the same amount of time to change stations.
- lmns 10y agoI know some Samsung TVs which receive Ethernet via HDMI. So all connected devices have to be offline as well.
- profmonocle 10y agoI wonder if you could make a filter of sorts that blocked the ethernet signals while still allowing audio/video? Sort of like those USB "condoms" that block data but allow power.
- prebrov 10y agoDo it on the router. I blocked my Samsung TV from accessing internet, but still allow it into LAN for DLNA.
- jghn 10y agoIt can be hard to unplug it. I have a 2014 Samsung Smart TV. I didn't want the smart stuff but there wasn't much option. When I first got it I gave it my wifi password just to check it out, confirmed that I'd rather just use my HTPC and turned off wifi. Lo and behold every few months something would happen which would make it clear that it was connected to the internet. I'd get banner ads. I'd get notices from the mothership about important updates. That sort of thing. Each time I'd discover that the wifi was back on and each time they'd have hidden how to remove it somewhere else. Eventually I just changed my wifi password and that seemed to have done the trick.
