Freebox Revolution HDMI problem not holding... Solved

Question

Hello,

I have a problem that I haven't found in the forum:

I've had a Freebox Revolution for a week, which I've connected to my Samsung HD LCD TV via the HDMI cable. So far, no issue.

Except that... after a certain period of time (which I haven't measured but is around 30 minutes), the HDMI connection drops. The screen goes black, and the TV displays "No connection, check the HDMI connection or check the cable signal." The Freebox remains on.

I then change the HDMI port: still no improvement.

I connect the Freebox and the TV via SCART: that works (but of course no HD...)

The next day, I try connecting via HDMI again: it works!!... for about 30 minutes... and back to the same issue!

I don't understand all this; apparently, the HDMI ports work on both sides, and the cable does too.

Could it be that the HD signal is too weak but strong enough at first, then not sufficient? Strange.

Do you have any idea what could cause this? And how to fix the problem??

Thanks a lot in advance!!!!

For your information, I haven't asked Free's hotline yet, as I believe there is no issue with the Freebox's operation, and I don't feel they are capable of finding a solution....

Hello everyone,

I also have a problem with video output via HDMI. It's not a bandwidth issue since the problem occurs even when we're in the menus. My TV displays "Incompatible video signal." This issue had already occurred from the beginning. I first thought about the refresh rate that I had set to 60Hz. The problem disappeared for a while. But now it's back. I will try switching to "Progressive."
The resolution setting is done in the Settings/Display/Resolution menu: Manual. I chose the resolution 1920x1080 50Hz Progressive.

I used to have a game (Tetris) that would crash systematically; the fault of... heat!

The Freebox is very sensitive to heat, so as soon as it gets too hot, it crashes. I think that might be the reason.

Don't place anything around the Freebox to see if that can solve the problem (I just had a stack of 5 DVDs on top, removing them fixed the Tetris issue!) especially don't put anything on top!

Let me know if that solves your problem :)

Thank you shikanara,

There is nothing on the freebox (well, there is the freebox, the freebox tv on it and nothing above) but the shelf is nearby. Tonight I will try to put one item per shelf and I'll let you know...

See you later and thank you!

Well, here it is:

Last night I turned it on all evening via the HDMI cable and it was fine!
I thought it was all good, until this morning: it didn't work right away! I turned on the TV and the Freebox and nothing...

Actually, the TV sees that a cable is connected, but it doesn't find any signal.

There you go...

I will call Free meanwhile, just in case...

Thank you!

It would be better to test with another HDMI cable. You can borrow one from a neighbor that works.

Hello, set yourself a little experiment
on the channel you are going to watch for at least half an hour, and with the remote control, display the menu on the TV (green button at the bottom left of OK), navigate down to video quality > OK and choose with up and down a format NORMAL or LOW BITRATE and observe what happens??
If all goes well and remains stable, you probably have an ADSL speed > atm down that does not allow HD display (>8000), the box being indexed as Auto, curiously prioritizing HD?
We'll talk more about it when you've tried this

Thank you all!

I called Free and they are sending me another TV box directly! (I tested with another HDMI cable, as well as the other HDMI ports, and with another HD device on the HDMI ports, which are working).

Free doesn’t want to understand, they are just changing the box!

I will still try Bernorenard's thing tonight to see! But that would mean I can’t have HD TV at home :(

To be continued ...

Hello everyone,  So, I've received the new HD box, it seems to be working.  Thanks to everyone for your help!  See you soon!

Hi,  There's nothing I can do, I've tried several resolution settings, it always ends up with a black screen and a message from the TV. I think I'm going to ask for an exchange of the box...
