Hi all
I'm wondering if you can help me, I have recently moved house and decided to ditch sky tv.... Sadly when I went to tune my bv10-46 in (mk2 with quite late s/w) it seems all options in the menu regarding tuning in the tv have disappeared! :( This leads me to believe the chassis has lost connection with, or is not seeing, the tuner module - Annoying! I checked error codes and there aren't any. All other functions work perfectly.
Is this a known issue? Does anyone know of a fix?
Any help appreciated as always :)
Can anyone help? I spoke to my local B&O dealer engineer who was all out of ideas. I've tried installing the latest dvb software but because the tv isn't seeing the module I can't carry out the update.
Does anyone have a guide to remove the rear panel etc? I am tempted to try and re-seat the tuner module and possibly check it for dry joints etc.
Hi a friend of mine has a BV10-46 which had exactly the same problem, we swapped out the main board
(eBay) if its on the option menu try switching DVB Tuner on and Off, perhaps a silly question but have you turned the DVB tuner on in the menu?

I would be surprised if it is anything to do with the DVB tuner otherwise you would get errors listed in the Service Menu
The first step I would take would be to go into the Service Menu and then select DVB Service. Does it say "DVB Connected Yes"? If it does it means the microprocessor is seeing the the DVB
Regards Keith....
Assuming step 1 is OK, then I would as if when you removed the Sky Box did you deselect the port used by it to None in the connections setting?
Hi Keith, thanks for the reply and advice :)
I can't see a separate DVB menu in the service mode, however when you go into the monitor info part (I can't remember the exact name for it, but it's the bit with the serial numbers etc listed) it says something like:
DVB HD: - (or NA or something)
I can take a photo and upload tomorrow. I've been through all the menus regards connnections etc and there isn't anything I've changed or deactivated. Also there is no option to select tuner type or do anything relating to the tuner or DVB. Does this help? I can take some sequential screen shots of the menus if you'd like?
the TV definitely has the DVB module? has it worked in the past or purely just used sky?
Yep, it's definitely installed and was working...
When you removed the Sky Box did you reassign the connection port from DTV?
Possibly!
Internal tuner was already disabled and Sky was assigned to TV... I have since done a factory reset which I thought would cure it but no joy so far :)

In my view based on your answers so far I would say that either:-
In the "Service Menu" the DVB should be shown as in the diagram below. if it does not show this, then my first check would be to test the 12 volts on pins 1 & 2 of J8 on the DVB board. You will need to get the help of a technician at your B&O dealer to perform this test.
Assuming the 12 volts is OK then I would do a forced software update.
Thanks for the detailed info Keith :)
I have uploaded a picture of my service menu so you can have a look... It doesn't seem to recognise there is a tuner fitted. Do you think if I get the local B&O engineer to do a forced software update it might help? Would this be tuner board or main chassis?
If it helps, I get the same on my BV10. I switched off the DvB and TV tuner when I got the tv so I could assign a different source to the tv button - now I can’t get to the TV tuner menu again. I don’t think that it is a hardware fault as both out TVs exhibit the same situation.
you should be able to get to the TV menu by hitting TV, then MENU, highlighting Options then GO, but I can’t get the menu to come up,when TV is selected - even from power off.
puzzling.
Hi, this is exactly what happened to my friends BV10-46, the DVB Module was switched off in the Menu when we tried to activate it in the Menu it was no longer recognized .
By the way this was a MK1 BV10-46 which was inspected by a B&O Technician who tried a few times to reinstall/update Mainboard Software without success, the MB functioned fine but didn’t recognize the DVB Board.

So further to my reply I would become a silver member of BeoWorld and then download the service manual for the BV10,
Undo the screws of the screen, take it off, undo screws of cover at bottom of TV on a dining room table GOOD HEIGHT TO SEE
then Release the ic pin power cable to the main board, plug in without DVB board connected then check Menus
Remove power, plug in board connection again and check if the Mainboard now can see the DVB board
Can be Bad main connection to main PCB
Mine is a MK2, so it looks like it is a design fault.

I would only restate my previous posting on this subject.
Back in October 2014 B&O reported to dealers that the problem you are reporting with not being able to see the DVB could occur if the 12 volt supply was low. Apparently, there was at that time quite a few power supply problems where the 12 volts would become low or fail completely.
So, the best way to determine if the problem you have is to get your B&O technician to measure with a multi-meter the 12 volt supply as shown in the diagram below. If the 12 volt supply is less than 11 volts the DVB will not work.
Frog, Douglas - Thanks for posting, it's good to know I am not the only one with this issue :)
Keith - That's really great info! I'll speak to my local B&O engineer and see if he can help me out... Sounds like it might be an easy fix if this is the case.I'll report back with my findings when I get round to having a look!
