Panasonic TV turns off by itself with SFR Fiber Box Solved

Question

Hello,
Since yesterday I have a Panasonic TX-40CX300E TV. It's a 4K television sold at Fnac. Everything was working yesterday! I had no problem, but this morning when I woke up, my TV started turning off by itself after one or two minutes. I looked for solutions and didn't find any. But there's something strange: when I play on the Xbox 360 (connected to the same TV), the TV doesn't turn off. And if I'm watching television and my Xbox is on, then the TV doesn't turn off.
So, since Panasonic's customer service is closed on weekends, I called Fnac's. The guy told me that it didn't come from the TV if it didn't turn off with the Xbox connected, but from the decoder. In this case, I have a Zive 4K Fiber Box from SFR. You understood that I am using 4K, except with the Xbox 360 which cannot be connected in 4K. I don't know if I should call SFR to send a technician or call Panasonic's customer service on Monday (it's getting expensive!), so I would like to have some information, please.

Best regards.

It's very possible; there may be issues with your distribution... it might not be completely sorted out yet... weren't you in 4K with your old TV..? so it never worked in that setup..??

depending on the length of the cable needed, it's not too expensive to try a temporary setup with a loose cable..

Good evening,

Did you have another TV before..? Did it do this..?

I still think that Panasonic guarantees your TV regardless of its peripheral connections..? It's possible that the problem comes from the Xbox or others. But to assert this cause without even having seen the equipment, I consider it laziness... and not competence.

Your TV arrives via the internet if I understand correctly..? And through HDMI..? And is it in 4K..? I have the impression that the TV turns off because it has no "video signal" or not the signal it needs, so it turns off.

Is it connected to the internet..? Maybe an update is missing..?

yes,

except that for the warranty, only what is written in the contract is legally binding. Everything that can be said to you over the phone is worthless...

-- So, this BOX is "4K compatible" which means that if you receive 4K content, it is capable of displaying it... But that does not prove that you are actually receiving 4K, in fact, it has never worked... at least in that mode... So, we don’t really know what type of signal you are receiving..?? At the end of 2015, there were only 1,000 municipalities equipped for that...

-- In short, if you connect the TNT antenna that comes down from your roof directly to the TV, does your TV work normally? That’s the first good question to ask.. Then, you can call the technical services..

-- There are probably menus to adjust, both in the Zive Box and in the TV...?? so that everything works..??

In TVs, there's a system, like a timer, that turns off the TV after a certain time, specifically for those who fall asleep in front of it or forget to turn it off when going to bed... maybe that's what's turning off your TV...???

This time is adjustable or can be turned off in the TV menus... You need to navigate through the menus or read the manual... or both..

The technician is not supposed to disconnect other cables in your house..
You should know if you have an antenna on the roof..?? If worst comes to worst, just look up and check... and the antenna cable should arrive in your home... because the primary function of a TV is to receive television signals from an antenna.. you need to know if that's how it works..??

This TV may have a technical problem..??

I think it would be best to talk to the seller so they can take action.

-- either they know the reason and can explain the process
-- or they are considering a warranty return or exchange..

It's possible that in a particular mode of operation it freezes and stops...
The description you give sounds like a safety feature..

-- Your HDMI cables correspond to an HDMI version... is it the right one..??

I don't have any other ideas.

In fact, we can't access your link; there must be a client number or a password...  So basically, if you don't say what it does, it’s useless..  Thanks anyway for the feedback.

OK, thanks for everything..  This is really very very clear and will be useful for those who have TVs of this family.  A+++
