From what I understand there is a Beosystem 3 in my BV7-40. But is it the same in the BV7-32?

Yes, starting from Mk3. But you said that yours is only 720p, so it is an earlier version unfortunately without it.  The BV7 televisions with the Beosystem 3 are the BV7-40 starting from Mk3 and the BV7-55 (all versions). All these are 1080p.

The BV7-32 doesn't have the Beosystem 3 processor.

I was constantly evaluating same idea, but then I realized above Marantz (which I like a lot btw) is around 2K EUR. Then add 3-4K EUR for a hiend 4K TV. Then add something to send it wirelessly to new Beolabs. Add value of a motorized stand. Add front speakers for non-B&O TV. And then you get to Avant 55" price +/-.

With a lot more boxes, wires etc. *sigh*

This link tells exactly the same 😁 ...

But it has a proper surround module?

Of course it is possible. It only depends on how much work you want to put into that.
The surround modul of the early BV7 have internally one s/pdif input and is controlled via I2C.
There is also an input for the PL data and all the PL sockets are directly onto that board.

If you really want to go this way you would have to get access to this PCB and either look for a datasheet of the used sound IC or hook up a logic analyser to the I2C bus to understand the commands for startup and volume control.

If this was sucessful you can remove the modul from your TV, hook up the right supply voltages and start experimenting with e.g. an Arduino to control that thing.

This would be indeed a cool project but a lot of work... 

You could look at the Loewe connect UHD, 4k and wil built in 5.1 surround, with a cable to connect beolabs.

not sure what they are like, but had good reviews. A friend has swapped over form a BV for the whole house and loves the TV

I was thinking about moving the BV7 to the bedroom, and simply run the sound from my Ps4 to it, and the hdmi from the ps4 to the new TV.

The only thing I am trying to figure out is how I should set it up to be able to watch the bv7 in the bedroom with sound without having the speakers in the living room on.

I guess one option could be to use the headphone socket to a BL15 or a pair of Bl4000.
