Downgrade MX7000 software

26 replies

In order to have two way communication between my MX7000 and my Beolink7000 I need to downgrade my MX7000 software (which is a 4.3 version) to 1.something. As far as I can understand such a downgrade consists of nothing more than changing an IC in the MX7000. However, some questions comes to mind:

1) How do I get my fingers in such an IC

2) Can I change it myself?

3) Does changing the IC bring unplanned (i.e. unwanted) consequences with it?

4) Has anybody experience with downgrading software in a MX-TV?

Thank you in advance.

Not too sure if it's all that simple, it could very well be if it's a newer (beo4, type 78xx) MX that even the infrared transmitters aren't fitted, you could check it under the toplid, that's the only thing i can think of just now.

Actually i don't know if there ever was a MX7000 2-way.... but if it is possible at all and your's is a beo4 type now it may very well be with the downgrade it'll become a link 1000 type (with different operation/menu).

Aha - but that is exactly what I am looking for. I am looking for turing my 1999 MX7000 operate acccording to link1000's menu's.

The reason for this, is that it will give me a possibility of turning the motorized stand under my MX7000 wih my Beolink7000

I know for a fact that MX7000 were made two way. link

It is just a question of software:  

I did I get the wrong end of the stick?

I think you might very well be right, Mika.

One way of solving the problem is to get an MX7000 with 1.something software - but then you have an almost 20 year old tv (my MX7000 is from 1999).

You write: "In addition, the old & new software might store all adjustment settings in a completely different way, meaning that the set would be completely out of adjustment once you boot up with the "new" (old) software." - but what are the exact implications of that? Problems that can not be solved with a Beolink1000? Which type of problems do you anticipate?

And finally - what do you suggest we do with the OP.

As long as the IR transmitting hardware is there i think you could easily swap the whole CPU board for an older version.

To re-adjust the settings, it might be sufficient (easy ?) to just access the current service menu and write down the vaules of the settings and set the values the same when the other cpu (or eprom) is placed.

It's weird that they put all the hardware in and not the software and actually i find the link 1000 software much easier and logical to use than the later versions.

Anyway, i might have a cpu/eprom from a scrap 7000 here, have to check though which software.

That might be the solution to my problem!

If one can mechanically switch the cp/eproms from one MX to another my question is how to get access to the service menus (I might be a B&O-nerd with some electronic knowledge, but I grew up with DOS and would thus have a fairly "mechanical" approach to programming - do you think that such a knowledge level would suffice?).

But thank you for spending time on the issue.

And thank you in adcance for investigating what sw your scrap 7000 has!

Best regards

Interesting discussion ... how about software from a two way MX4000?  Surely this would work?!

Neil

I actually have a MX4000 a home which works fine two way with my Beolink 7000. Are you suggesting, that I switch the cpu with eac other (I d not need the two way communication in the room where the MX4000 is)? That would indeed be an easy way to solve my problem, but it also sounds like I am potentially throwing a spanner in gear box - or am I being uncoragous?
