Something very weird happened this morning at 3:20 am

Sorry, EAS, or EMS. Whichever it is.

I'd be on the phone calling anybody who might have answers....

I have my laptop pc hooked up HDMI to a 32 inch television. I had a screensaver set to come on when idle, but one night I shut it off and have not set it back since.

NOW....

When I am not using my pc, the television will turn itself off...(POWER DOWN)...but then, it will turn back on again after a bit, seemingly random.

It cycles on and off by itself.....all the time, when left alone. Either my wireless mouse is activating it, or a setting on my pc through HDMI.

The first time it did it, it freaked me out. Now, I just ignore it mostly, because I don't care.

smart tv?

Its because you got smartTV they do stuff on their own. Mine acts the same.

what part of the country are you in?
could be you are in a test area and something is up that needed testing?

Yes

Lubbock Texas.

Smart TV showing you if their had been a disaster you would know...

If you have a smart TV it can easily turn on by itself. I even have an AVR that turns on by itself for no reason.

Think tv remote from a distance.

Anyone will a smartphone remote control app and an unobstructed view of your television, knowing the model, can use your television to troll you.......BUT.....an EAS alert at the same time, makes it unlikely that's the case here.

so Alexa and smart tvs will act as an early warning system when a nuke is flying our way?

that's interesting.

this is the same technology used to remotely hijack flight MH370 out of Indonesian airspace.

Wake On LAN

Your TV is a “smart” tv and you have it attached to your network.

It received a “wake on lan” packet and powered up.

Computers have had this feature for 20 years.

The next time it does it, I would pull out my pud and start wacking it in front of the tv and say, "Is this what you want, IS THIS WHAT YOU WANT". :o)

If you had on older TV and there was a disaster, you'd never know until the next day. I guess it was a test to actually 'wake up' the tv so you would be informed.

I am assuming the volume on this test was much louder than your normal volume level?

Since you wrote 60" the TV must have HDMI inputs.

A feature of HDMI is CEC and MHL. CEC stands for 'Consumer Electronics Control' which allows one HDMI device to control another. [link to www.howtogeek.com (secure)]

Your TV was off. The EAS alert was activated so it sent a CEC command via HDMI to turn the TV on so you would receive the alert.

It's not spooky or freaky, just an HDMI function you were unaware of.

If I power on my DirecTV receiver my TV will power on because of the CEC command sent by the DVR via the HDMI link.

MLH is the technology that allows your laptop or tablet to detect the TV and instead of displaying the media on itself, it instead send it to the TV.

I can view this web page on my MS surface, but with one click of the mouse the audio and video is instead sent to the nearest TV in the house.

When my Samsung Smart TV was destroyed by a lightening strike, I replaced it with a Sharp (lower price as they are mad by Hi-Sense) but I wish I would have bought a Samsung after the fact (superior TV) and added a UPS between the mains and my home entertainment system. I noticed as everyday when I came home from work the cats were lying watching it.

At first I thought kitteh had figured out the remote control and was powering it on, but upon investigating found that the DVR would power on to record the news and at power up it sent a CEC 'on' command to the TV which then powered on. I had two choices to fix it: have the DVR remain on or disable CEC control on the TV. I chose to have the DVR never power off so when it records a show it no longer sends a power on command to the TV.

I hope this helps.

The night before last around midnight my tv started screaming. I was dead asleep and the thing turned the volume up all on its own full bar. It’s an older tv. Shortly after that my dog went to the edge of my bed and started growling like something was there. I jumped up to check on the kids and all was well but she did this all throughout the night. It was kind of creepy.

Poltergeist...

Not all digital TV's can see you, but all are aware of ambient lighting and if you have configured them correctly they will adjust the picture to match the ambient lighting in the room.

I was awakened at around 4am....startled. My iPhone was giving off a loud piercing sound. A flood warning. I'm not even in a flood zone. Scared the heck out of me. It's barely raining outside. I live in the northeast.

ok, but the fact that an actual EMS or whatever it's called happened???

has anyone else received an Emergency Broadcast System Alert on their tv? recently?

like the Hawaii false alarms? maybe?

For what it's worth I routinely leave my phone's camera pointed at my junk; if someones watching they'll get an eye full. Similar in effect to answering a reporter questioning if you know someone to replying "Yes, I do. I believe they work for a feminine hygiene company, their product is called 'Sprunt'".

Why the hell would they do an EAS test at 3 am and scare the shit out of everyone? A real emergency like a tornado sure but a test at 3 am.

65" in your bedroom is pretty excessive, lol

Way to point out the ELEPHANT in the room! lol

My Sony HD (not smart to my knowledge) does the same.
Comes on with the EAS alerts and stays on, continuing to
broadcast what sounds to be a radio station, though I haven't focused in on the broadcast yet. (In New England)
