Problems to connect the Raspberry with the Beovision 7.40

Does anyone know how to connect the Raspberry PI B2 to the Beovision 7.40? I don't get a connection. It stays black.

Hi Brimbay and welcome to beoworld.

Which version of the BV7 do you have? An earlier one with DVI connection or a later one with HDMI ports? (It would be easiest if you could tell us the 'type' number on the back of the TV if possible).

How are you connecting the RPi to the BV7? HDMI or composite video?

Kind Regards,

Martin

Hi, I think I had the same problem, but it can be solved easily. The issue is the hdmi /dvi handshake that both the rpi and the bv are looking for. If the rpi does not get response from the tv, it falls back to the analogue output. If the bv does not get an image on the digital input, it also disables it (I think). Anyway, there is an easy way to check the working of the rpi: also connect the video output to one of the slots on bv40. If that works, hdmi handshake is in fact your problem at hand. The solution is to add 1 or two lines to the boot/config/advanced settings file, depending on the software on your rpi. What are you running? My experience is with raspbmc, but that does not exist for your rpi model I think. You can google for your operating system + hdmi_force_hotplug=1, and you will find where to put this line. If you cannot solve the problem let me know, I have spend hours on setting everything up and I am happy to pass the knowledge on!

If you need more help, let me know, I have spend so much time setting everything up that I would like to share my insights :)

@ moderators: on the iPad there is no notification if a post is send for review, (because it blocks popups?), so I thought the post was gone, and partly typed a new one. I am not able to edit a post on iPad, so cannot delete the post, or the content...

I'm painfully aware of that problem, but unfortunately I don't think we can do anything about it (at least cost effectively). Moderating is equally painful on an iPad so I generally just approve everything from the queue if it looks all right - checking whether the same or similar post has already gone through is just too difficult and time consuming.

Appreciate what the moderators are doing - they are doing their best :-)

I post a lot, but it does not really happen that often, that a posting 'disappears' - imo!

However, when writing a longer post, I have made it a habit - before pushing the button - to copy, what I wrote.....just in case.

hi, thnx! I connect the rpi to hdmi 3. Therefore I've tried to add the following lines to config.text (I've delete the standard lines: # Force HDMI even if unplugged or powered off hdmi_force_hotplug=1 disable_splash=1 # Doesn't sent initial active source message. # Avoids bringing CEC (enabled TV) out of standby and channel switch when # rebooting. hdmi_ignore_cec_init=1) I've replaced the above lines with: # Force the monitor to HDMI mode so that sound will be sent over HDMI cable hdmi_drive=3 # Set monitor mode to DMT hdmi_group=3 # Set monitor resolution to 1024x768 XGA 60Hz (HDMI_DMT_XGA_60) hdmi_mode=16 # Make display smaller to stop text spilling off the screen overscan_left=20 overscan_right=12 overscan_top=10 overscan_bottom=10 That didn't work. Do you now which line I should replace the standard lines with? I've used HDMI C - AV3 (this entry).

Hi, thnx! I've done the following (I still don't get any image on my bv (= tv)): I've replaced the standard lines in config.txt with: # Force the monitor to HDMI mode so that sound will be sent over HDMI cable hdmi_drive=3 # Set monitor mode to DMT hdmi_group=3 # Set monitor resolution to 1024x768 XGA 60Hz (HDMI_DMT_XGA_60) hdmi_mode=16 # Make display smaller to stop text spilling off the screen overscan_left=20 overscan_right=12 overscan_top=10 overscan_bottom=10 I'm using HDMI C AV3. But it doesn't work. What kind of lines did you replace the standard lines with? The following standard lines I mean: # Force HDMI even if unplugged or powered off hdmi_force_hotplug=1 disable_splash=1 # Doesn't sent initial active source message. # Avoids bringing CEC (enabled TV) out of standby and channel switch when # rebooting. hdmi_ignore_cec_init=1 Thank you in advance!

Of course!

've replaced the standard lines in config.txt

Can you first tell me what OS you are running on the pi? Because it makes googleing your problem a lot easier ;-). And every system is different, e.g. I had to create an advancedsettings.xml file with the content that you describe.

To answer your question: I'm using "openelec Version 5.0.8 (Kernel Linux 3.18.10) " as OS on my rpi. I don't know how to create an advancedstettings.xml file. Did you set these lines in the config.txt or did you create a whole new file, and how did you connect that to the RPI?

Starting with the default config.txt (the one supplied with openelec) please edit the line:

# hdmi_force_hotplug=1

to instead show:

hdmi_force_hotplug=1

(ie remove the # from this line)

then also add a new line with the following:

hvs_priority=0xf3fc

Save the file, and boot the RPi again. This will resolve two potential problems, HDMI detection and an HDMI dropout issue that can also result in blank screens. Please don't change any other line in config.txt at this stage  as multiple changes can make problems more difficult to diagnose.

Please let us know the outcome once you've tried this.

Kind Regards,

Martin.

 

Hi Martin, I''ve followed your instructions, but there is still no image on my tvscreen. It stay black.What to do next? Thanks in advance. Kind Regards Bert

Hi Bert,

That's rather strange, I've just tried out exactly the same setup with my BV7-40 mk3 by installing openelec 5.0.8 on a spare SD card and making the config changed I suggested and it is working fine for me.

Do you have any other television you can connect the Raspberry Pi to (using the same HDMI cable)? This would help to rule out either a fault with the RPi or a fault with the HDMI cable.

Also, do you have a set to box or DVD/Blueray player you can try connecting to the BV7 using the same port and cable to see if you can achieve a picture with a different device?

Finally, let me know the 'type' number printed on the label on the back of the BV7, and maybe take a photo of the AV3 connection config screen on the BV7 so we can confirm the input is configured properly.

Kind regards,

Martin.

 

Bert,

I sent a reply with some more suggestions but it has gone for moderation (but should appear soon).

In the meantime I had another thought - are you sure you are using the right openelec image for your RPi 2 model B? You must use the 'RPi2' image, eg:

OpenELEC-RPi2-arm-5.0.8 (and not OpenELEC-RPi-arm-5.0.8)

Kind Regards,

Martin.

Hi Martin, it's working :-)!! I've connected the rpi to the v.mem (this is were I had connected my Apple tv) + used your code. The only thing is that I have to shutdown Apple tv if I want to use the rpi. And vice versa. I'm very greatfull for your help! Kind regards Bert

That's excellent news, we should now be able to get this set up on it's own input so you don't need to swap between the Apple TV and the RPi, especially as we know the RPi is now working correctly.

Given it is now working using the Apple TV input (and presumably the same cable you use with the Apple TV) there are two possible reasons why it did not work on AV3 - either the HDMI cable you were using before is faulty, or AV3 was not correctly configured on the BV7.

Press MENU, then select CONFIG and press GO, then select AV3 and press GO.

On this screen:

Set SOURCE to whichever button on the remote you want to correspond to the Raspberry Pi.

you can set NAME to Rasp.Pi or similar if you wish (this is optional).

set HDMI to A, B, C, or D - corresponding to whichever HDMI port you will be connecting the raspberry Pi to.

set SOUND INPUT to HDMI

press GO to save the configuration, and then EXIT to leave the menu.

Now (with the TV turned off) connect the Raspberry Pi to the HDMI port you chose above, press the button for whichever SOURCE you chose, and see if it works as expected.

Please let me know how you get on.

Kind Regards,

Martin.

 

Hi Martin, you were right. The problem were the cables. I've changed them and the rpi and apple tv both are working. I don't have to switch cables anymore. I'm greatful for your help! Without it I wouldn't have solved the problem. Thnx!!! Kind Regards, Bert
