Hi Dargo – there may be some info in this post which may help. Circuit diagrams etc no longer available.

Beolab 14 Sub – IC identification needed !

Beolab 14/BeoPlay S8 – Amp not working

[Jonathan McCall]

Any joy Jacob ? Funnily enough there’s a post re and S8 not powering up. Looks like the capacitors could be an issue.

Cheers

Very useful post – many thanks. Can a blown IC also take out a cap or two ? Jacob and I are currently experiencing no power after a blown IC. He’s on an S8, I’m running a Beolab 14.

Thanks

Jonny

Many thanks Mat j’adore 🙂

Will do some more googling. Don’t want to spend £80 or so and find out I’ve got the wrong bits.

[Jonathan McCall]

Had a look behind me and under the bed, but couldn’t see any…

Perhaps I should explain a bit further – I can find slats,  but not sure whether they’re sufficient quality, look good etc etc

Im hoping that someone who has done this can share what they used, where to source them etc.

Thanks !

Hi Jacob – haven’t revisited I’m afraid, I was away at the weekend and had a ton of things on since. Did you try the green button ?

I’m afraid I wouldn’t know where to start, looking at the individual smd’s, even with a circuit diagram I’m a bit lost when it comes to testing the  various components.

Would obviously be very keen to see if you get any joy.

Cheers

Thanks for the update. My cable arrived from Steve along with helpful instructions on which of the 4 sockets to plug it in to. Turns out I was using all the wrong options.

Still doesn’t work.

Will hopefully be able to get some time on it at the weekend and see if that little green micro switch needs pressing.

Good luck !

[Jonathan McCall]

Will see if I can get some later.

[Jonathan McCall]

Wonder if that’s the same on the 14 ? Must admit, I didn’t seem to have any mounting issues.

How far apart are the 14 and S8 in terms of design, componentry etc ?

[Jonathan McCall]

Are you sorted Jacob ? Hopefully you’ve got it all working again.

[Jonathan McCall]

Good luck – interestingly, I found a green micro switch tucked away on the ICE board. Tried pressing it with power off and with power on, but no change. Could be that it needs to be held in for a few seconds ?

Just surmising of course, but there must be a reason for it.

[Jonathan McCall]

Thanks – that’s interesting. Although I’m getting nothing.

Could be a dicky Powerlink cable, I’ll do a continuity test on it tomorrow.

Appreciate the help.

Jonny

[Jonathan McCall]

Thanks for the quick reply. The only light I can see is a white knob type thing underneath. Bear in mind I’ve never had this working, so don’t know the functionality etc.

Nothing lights up at the moment.

Cheers

Hi Jacob – hope all is well. Did you get your diode swapped over ?

My Beolab 14 is back with me and all connected up, but no switching on from the Powerlink connector. I’m using a Powerlink to RJ45 connector, but no response from the sub.

I’m wondering if I’ve missed something fundamental, although all connections are connected, even that pesky ribbon cable.

One thing I’m wondering is whether I have a missing connection right in the middle of the ICE power module. There’s a block connector socket on the left hand side of(opposite to all the caps), approx half way up. Is yours inhabited ?

Another thing that’s occurred to me is whether there’s a reset switch that needs a prod ?

Cheers

[Jonathan McCall]

All back together – just awaiting my Powerlink to RJ45 cable so I can test it.

[Jonathan McCall]

Brilliant – so it’s external to the pcbs. Makes sense now.

Will have a look tomorrow.

Great team work !

Cheers

It’s been a while since I took the think apart and I’m progressing well on re-assembly, although I’ve hit a headscratcher I hope you can help with Jacob.

I have a ribbon cable, which doesn’t stretch very far and appears to be folded back on itself. I’m wondering if it goes to either of the 2 connectors shown in the pic. There’s no connector on the end, so thinking the top connector might be the one, but it really struggles to get anywhere near it, let alone slot in. It could be that the connector has come off the ribbon whilst it’s been away, but don’t think it likely.

Could be that the 2 connectors are redundant, as is the ribbon ?

All the connections on the board with the blown IC are mated up with their respective cables.

Cheers

Jonny
