Great news – I am glad you got it all working, and thanks for letting us know! ?

Also, if you do manage to get back into the Service Manual, can you tell us the ‘Type No’ that is on the Monitor Information page?

I don’t think PC should be present on the TV’s ‘connections’ menu; it is usually just accessed by pressing PC. Once PC is selected as the source, the only other menu available is the Brilliance, Contrast, Colour one that you saw before.
Can you still get to the Service Menu? (Using MENU 0 0 GO) – only avail when in normal TV mode, not PC.
If so, go to ‘Monitor’ then ‘Picture Adjustments’ then ‘Scaler Test Menu’. The bottom line of the Scaler Test Menu should state ‘DVI DETECTED’ with a Yes or No.
To be honest the Service Menu may be different for various TV software levels, so I would have a good look through every menu for any mention of DVI.

Sometimes it can take a little time for the handsets to update with the phonebook and/or handset name.
Also you could go to the original handset ‘settings’ menu, scroll to ‘handset’ menu, press centre then scroll to ‘handset type’ and make sure it is set to ‘common’ and not ‘personal’. This should force it to store the phonebook on the base rather than the handset.
EDIT: Be careful if you change from Personal to Common because this will delete the Phonebook. If it already set to ‘Common’ just wait for it to update!

Hopefully the PSTN button press will work for registration, but if you do end up replacing the batteries I usually buy these ‘Cameron Sino’ ones – they seem to work well: https://www.ebay.co.uk/itm/112488682394
(I don’t necessarily use this eBay supplier – it’s just an example to show the batteries I use.)

My BV6-26 was probably just as old (with an analogue tuner) and also had started life in a hotel. When using the DVI input my two problems were firstly getting the resolution right (as we have discussed), and secondly High-bandwidth Digital Content Protection (HDCP).
As far as I am aware, TV’s that are not HD-ready cannot display an hdmi signal with HDCP. You may find that you can go into your IdeaCentre’s graphics settings and turn off HDCP to see if this is the cause of the problem.
When I used an Apple TV with my BV6 I also used an audio extractor (to get the sound out of the hdmi) which had the advantage of stripping the HDCP from the signal so that the TV would display it.
I described my DVI experience in this post: https://forum.beoworld.org/forums/topic/hdmi-connection-for-beovision-7-mk1/#post-1707

Tried that, without pc output and with output, the option is just test patterns the DVI is not highlighted and cannot be accessed. The Type No 9252 Item No 1816658
So that is a Mk1, whereas my BV6 was a Mk2 (Type number 9272).
I still think there may be an HDCP problem. Have a look at this old thread (you need to translate from French) about a similar type BV6-26 (type 9251) where the owner had to use an hdmi splitter to remove the HDCP. For my TV, I managed to use an hdmi audio extractor to strip the HDCP.

But of course, if even selecting the PC input is not possible (since the reset) then you are unable to try something like this.

Hi, I do have a BC6-26(9280), and I do recall that I had to put the ‘HDCP mode’ setting to ‘hdmi’ or ‘disabled’, where ‘HDMI’ worked for my AppleTV
I remember that too for either my BV6-26 or BC6-26, but I couldn’t find it in the Service Manual for the earlier models. Hopefully stotty can find it, otherwise I have run out of ideas other than taking the TV aspart to see if any hotel (BtB) hardware is left inside!

I think with that PSTN base there is a button (B on the diag below) that you have to press for at least 4 seconds to open the base for registration:

Ok maybe have a look in the service menu. Two things to try:
– Look for a ‘BtB’ setting and see if you can turn it off. (This is the Business to Business software that the TV would have used when it was in a Hotel).
– If the above doesn’t work, you could try the TV’s ‘reset to default’ that should be in the ‘Monitor’ part of the service menu.
Also it may be worth trying another hdmi -> DVI lead – they are not all wired the same way.

Further to the above, the maximum resolution of the BV6 screen is 1280 x 768.
If you are using Windows 10, go into the computer’s ‘settings’ then ‘display’ menu, and try adjusting the ‘display resolution’ figure to match the TV. You could also use the multiple display menu (or ‘advanced display settings’ menu) to control what the PC is outputting on its hdmi socket.
EDIT: Before adjusting anything on your PC, note the current display settings so that you can restore it to the original state!

Thanks for splitting the topic!
No problem – it seemed sensible.
DVI socket, with connection to an HDMI socket on the pc, pressing menu gives a screen showing state of brilliance, contrast, colour, and sound , no screen showing pc output, perhaps that part of the tv programming is inactive, can it be activated? if so, how? and by me?
So I assume that you have selected the DVI socket by pressing PC on the remote.
I would check the PC’s hdmi output initially – you want to make sure that it will output something in a resolution compatible with the BV6 so you may have to experiment within the PC’s display settings. Also, the PC’s hdmi socket may not be active by default, so you may need to use the computer to turn it on and then decide whether it is an additional screen or a mirror of the main screen.

You replied just as I was splitting your BV6-26 question to a new topic, so I have moved your response to there and will reply.
Let’s keep this thread related to your Ouverture question, which you were going to investigate further as you had found the circuit diagrams..

You could try a reset of the handset. You can get to the Service Menu by pressing 9#9#9✱INT and then scroll to find ‘reset handset’.
Alternatively, use the other (working) handset to see what other handsets are registered to the base. Go to the normal ‘settings’ menu, select ‘Base’ and then ‘Remove Handset’ to see what else is registered. If the ‘unconnected’ handset is listed there, you could try removing it and then try re-registering.
What sort of base/PSTN are you using?

Interesting results so far – the fact that the MCL2AV AUX socket connection allowed control was useful, but I too don’t understand why there was no sound. I thought that pins 1 and 4 always output the sound from MCL2AV.
My gear is put away at the moment so I think it will be next week before I am able to try anything similar (with a known working MCL2AV), but until then I will be following with interest!

There’s often compatibility problems between older phones and newer PSTNs.
Here’s a compatibility table that Keith has produced in the past:
(A ‘X’ means that it works, but you have to read the footnotes)
And this from the Beocom 5 manual:

I have just been reading through the rest of this thread – some great detective work! The requirement for pins 3, 5 and 7 to be connected is indeed strange!
One thing to note from this test is that the BM5500 is the only product where I have found that the data pins in the Aux connector and the MCL speaker connector are connected internally in the Beomaster, so the result of this test might not be the same with other audiomasters.
I think BC9500 is the same (TV AUX pin 6 connected to MCL speakers). So the data going over an MCL system is Audio Aux Link (AAL).

thanks for the input. Is it mentioned in a manual or guide somewhere? The reason for asking this is if this is for a connection with Masterlink or Powerlink?
I have linked to a PeterPan thread before that had the following note under a post about BL3500 and Wireless 1 – perhaps this accounts for the Option 0 setting (when using the first version of Wireless 1):
NOTE
The combination Wierless 1, version no. 1780 and BeoLab 3500 version no. 1601 must not be connected to a separate IR-Sensor, here the IR sensor that is built into BeoLab 3500 works.
Installation of a separate IR-Sensor therefore only applies to the first version of Wireless 1.
Here’s the thread (I used google translate – 3 Mar post refers): https://www.hifi4all.dk/forum/forum_posts.asp?TID=20679&PN=1&TPN=149#top

The powerlink data pins also has connection to this transistor, on the line going out to the left side of the diagram.
That was well spotted – I took a while to find that link even after you had explained it! It does add an extra level of complexity o-if third-party devices (like the Almondo) are added to the datalink/powerlink setup, and I am not surprised that it can present problems in some circumstances.

I vaguely recall the key to access the inner memory setup features on theBV tv’s is menu 0, 0 go,
Service Mode is indeed accessed by going to a SETUP menu and then pressing 0 0 GO
But the DVI socket is usually selected by simply pressing PC on the Beo4. I doubt that it has been disabled due to the previous hotel use, so I would definitely try this first.
You may have to add PC to the LIST button on the Beo4.
EDIT: As you are a GOLD member, you will be able to view the Service Manual on site – there is some useful info about service mode. Try not to muck up any settings – it is often best to take a photo of the screen before changing anything!
