We bought a Panasonic 40" (40C400Z) to update our old CRT 27". After hearing the decidedly mediocre sound quality (why can't lower-end televisions include great sound?) we also added an LG soundbar a few days later. They both work well enough together. However, the Panasonic has started showing a weird little problem.


Every so often, I'll wake up during the night and wander past the soundbar and notice that it's been turned on recently and hasn't shut down again. The television can activate the soundbar when the television turns on, however the television hasn't been on, nor had I turned it on. The only reason I actually noticed is because the display on the LG soundbar says "Optical" instead of being blank in power-save mode.


This morning, things were a little different.  At 6:03 am I turned on a bedside light (CFL lamp), and after about a half minute or so—the average boot-up time, the television turned on in the lounge with Peter Williams reading the 6:00 news. I didn't press any buttons on the remote, I didn't even press a button on the television itself, just turned on a light.


To the best of my knowledge, the television doesn't contain software to turn on at a specific time, nor would I have chosen to wake up with the birds. It shouldn't have an ambient room sensor, I don't see anything in the manual to indicate that. It was a "not-so-smart" television chosen specifically because it didn't have the fancy Smart features users seem to love, nor does it have wireless. And the problem only seems to occur when I turn on a light in the morning, ready to head off to ... well, you know where. 


Is it time for a firmware update? Does Panasonic really think that Peter Williams can improve my life just by listening to him? Or do I really have to jack up another courier to drop this television back to the place I bought it from?

It could be several things.... My father-in-law's TV was doing this. I narrowed it down to a couple of things...


1. Automatic software update. It was set to 3 am.


2. They have a UFO universal remote for the Sky box and I suspect a neighbor has the same device on the same frequency....


I put a piece of cardboard over the IR blaster to stop it heading towards the TV and turned off auto software update. I am not sure which one fixed it....


Cheers, Matt.

Oops. I didn't read all of your post. Disregard the part about auto software update. Is light line of sight to the TV? 


Here is your answer:

I've got a USB based IR should see it go nuts when i turn on my lights.  They're energy savers, not LED, fluorescent maybe?  Perhaps transmitting on the frequency your tv needs?


Oh and readying further it doesn't sound like your light could be causing the problem.

Try turning off the Viera Link in settings and see if this stops this.

I have same issue with my Panasonic but mine is cos there is a 40m HDMI cable from the Skybox in the bedroom all the way on other side of house to the Study so I can have a pretty sports picture when on pc. If for some reason that cable becomes active (ie turn on TV or Sky in Bedroom - yes both even tho sky backfeed is not via the TV) the Study TV turns on or off. And sometimes same in reverse turn on study Panasonic and bedroom Panasonic can come on as well. 


I live with it and just make sure both have an auto off set on them. Not sure if helps but yeah in case you have an HDMI between them .....

Well, I finally figured out that it doesn't seem to be because of the CFL in the bedroom, (1) it's too recent a CFL, (2) the telly turns on the soundbar whether or not the light's on and (3) the television turns on the soundbar at 06:00 every morning in DST, and probably 05:00 every morning in non-DST, though I haven't verified that. I'm leaning more towards software update check. Thankfully the television doesn't out-and-out turn on any more. Maybe it decided I didn't like Peter Williams or something. Why don't Panasonic let you know in that wonderful manual of theirs, nor provide a switch in the settings to choose what time it checks?

The telescreen was giving forth an ear-splitting whistle which continued on the same note for thirty seconds. It was nought seven fifteen, getting-up time for office workers. Winston wrenched his body out of bed — naked, for a member of the Outer Party received only 3,000 clothing coupons annually, and a suit of pyjamas was 600 — and seized a dingy singlet and a pair of shorts that were lying across a chair. The Physical Jerks would begin in three minutes. The next moment he was doubled up by a violent coughing fit which nearly always attacked him soon after waking up. It emptied his lungs so completely that he could only begin breathing again by lying on his back and taking a series of deep gasps. His veins had swelled with the effort of the cough, and the varicose ulcer had started itching.


‘Thirty to forty group!’ yapped a piercing female voice. ‘Thirty to forty group! Take your places, please. Thirties to forties!’


Winston sprang to attention in front of the telescreen, upon which the image of a youngish woman, scrawny but muscular, dressed in tunic and gym-shoes, had already appeared.
