MX7000 doesn't store settings when powered off

I can't get one of my MX7000's to properly store settings after soft power off. First it didn't store anything but eventually started to retain settings, but no matter what I do, it always returns to 'speaker 3' in the sound menu.

First, I don't know what that setting does and none of my other BO's have it and I have to set it to '1' for it to produce sound properly, and it always reverts to '3' after powering off.

How do I fix this?

It looks like your MX7000 thinks that there are external speakers attached.

If you don’t have any external ones, go to the speaker setting page, remove any Beolab speakers you find there, then come back to the screen in your photo, set SPEAKERS to “1”, and Centre volume to 40, or whatever volume level you want it to be at when you turn it on. Press GO or S.STORE (for SOUND STORE) to save your settings.

Wait, I have no idea what you just said... remove speakers in speaker setting page? S.STORE? I have no idea where to find this, they aren't in any menus.

Edit: Right... I found S.STORE (I still have not found anything even remotely named 'speaker setting page', though) which you'd think is in A.SETUP but it wasn't, it's in V.SETUP but only if you add A.SETUP to the LIST which doesn't show up on its own even though it's ADDed in the LIST but somehow resides inside the V.SETUP menu... which is not how my other BEO4 works, there A.SETUP shows up in the LIST but that has a cracked LCD and I can barely see what's on it so tough luck there.

Anyway, S.STORE doesn't do anything, you'd think it stores things, but it doesn't, 'Speaker' in the 'Sound' menu is still set at 3 even though I change it to 1 and press S.STORE which I can either change via MENU to either 1, 2 or 3 or with SPEAKER in the LIST and I can press 1-3 on the remote, even though the manual say I can press 1-5 and you'd think those numbers represent the number of speakers but why would you want 1? You'd think that's mono, but no, it's still stereo with 'Speaker' set to 1. To say this is confusing is an understatement.

Only when 'Speaker' is set 1 it works with 'Centre' at 00, otherwise 3 works with 'Centre' in some random position except 00 but only up to 40, it stops affecting the sound at 40 even though it goes up to 80. But if it's set to 3 then it just sound muddled and thin so I want it set to 1, whatever that means... yeah, this is... I'm three hours in, googling, posting here, reading the useless manual and pressing every button combination there is and all I want to do is store the damn setting to 1 so I don't have to change this every time I power the TV on. And I have five BO's, three MX4000 and two MX7000 and none of the other TV's does this and neither of them have the 'Speaker' or the 'Centre'.

How do I fix this...

Edit2: Oh my God... to fix this, and it was just some random thing I tried, you have to go into Setup and Sockets, there is a setting called PL, which makes all kind of sense and is self explanatory, and set this to 'Off'. PL apparently means, which I had to google, fetch a manual and search in the manual to find, Power Link, which is some speaker... thingy, because of course it is. When that is set to 'Off', the 'Speaker' And 'Centre' goes away from the 'Sound' menu and it will save the setting and survive a power cycle. This is why all my other BO's didn't have this issue, that setting was always set to 'Off' and never changed by me after acquiring the TV simply because I never knew what it meant or did. Who does.

Jesus. Four hours did this take.

Persistence pays off 😊

I’m glad you learned something about your Beovisions and their sound potential.

Yeah, I learned nothing of any sound potential. I did learn how not to write manuals, how to put wrong things in the wrong section and how incredibly frustrating it it to operate this, quite frankly ordinary TV. The menu system and the remote is a complete and utter disaster. Power Link? How about calling external speakers External Speaker instead and put their on/off section in the 'Sound' menu where it belongs and even if you have them configured in the system regardless if you have them hooked up or not, still save the damn settings. Why have the ability to change it to internal only yet deprive the user from saving this setting? It's ridiculous.

As good as the on-board sound is, you have the potential to substantially increase the scale and depth of the TV’s sound by investing in a pair of Beolab speakers, e.g. BL6000, BL8000 or later. Keep reading and listening - you have chosen well.
