Hello, I am new to the forum and hope I can get some advice regarding a Beomaster 5000 Type 2322 which I acquired today.
The unit powers up OK and it recognises the deck (Beogram 5005) and there is audio output too. The problem I have is that the front panel doesn't open when the open button is pressed and none of the controls work when pressed either. There is no remote control with the unit so I need the built-in control panel to work.
Does this sound like something that could be a relatively easy fix, or is it going to have to go to an expert service engineer?
If I tackle it myself has anyone encountered and fixed a similar problem?
I have downloaded all the service manuals and user manuals just in case.
Thanks
Nick
Broken ribbon cable from the front panel to the connection board.Common fault.Bridge it with thin flexible wires.(A bit fiddly)
Martin
Thank you Martin
I will begin as you suggest and will let you know if it solves the problem.
OK. I have exposed the ribbon cable (see attached pic) and it looks to be the offending part, thank you Martin :)
Before I attempt the repair, I'd like to just check I'm going to do it correctly. On the attached picture I have numbered the connection points and drawn a double ended arrow.
I would like to make a once-only repair so your advice would be most helpful.
Thank you
I think all 10 pins are used.The others may have been soldered on the other side of the board.
Yes, bridge them one by one using thin insulated leads.There's not a lot of room for thick cables, but desoldering and removing the broken ribbon cable frees up some room.
If it helps, I’ve repaired two of these using computer ribbon cable - it’s small and flexible and fits into the space available nicely.

Did that involve dismantling the front control panel to get to the back of the pcb?
It will be much neater if the broken ribbon is replaced with a new piece of ribbon, so I like this idea, but I am concerned disassembling the control panel is going to be tricky and/or might damage the buttons etc.
Is disassembling the control panel straightforward, and if so, how is it done and what precautions need to be taken?
Thanks.
Nick.
Yes, it involved dismantling the control panel. It’s a bit fiddly but not difficult!
You'll note that none of the other 3 stacked Beosystems had a drop-down drawer similar to the 5000.
-The controls on the receiver were insufficient to control necessary functions such as. bass, treble, & balance.
-Remote control operation is so much more convenient. You'd be better off just getting a Master Control Panel 5000 (6 currently listed on US eBay) and, optionally, a Terminal 5000 for day-to-day hand-held remote operation.
Right. I will see if I can dismantle the control panel in order to carry out a nice neat finish. I know it won't make a jot of difference for operational purposes, but it will make me feel better about it. Daft, or what eh! :)
Once I'm sure the amp works perfectly I'll also see about getting one of those remotes too.
All repaired and working beautifully
Thank you all for all your input and assistance. I couldn't have done it without your help.
Next I have to repair the Beogram CD-50.
Oh, and I have now bought a Master Control Panel too.
Saint Beogrowler:Nice work. The CD50 Is great when it is playing
But not quite as easy a repair...
I have five or six BGCD-50's,and probably need therapy too?I just like them and the sound quality they produce.
They can be "challenging" to repair as Martin suggests,and I have the teeth marks along the edge of my work bench as testimony to that.Very satisfying to get them working well again though!(the CD50,not the teeth!)
Well, I'll open it up at the weekend and see if I can work out what's what. I thought I was just going to have to sort out the disc drawer, which has slipped out of its guides, plus the drawer door which hangs slightly open. But I have a more serious problem. I had it plugged in and on standby when all of a sudden there was a bang and smoke. I'm hoping it's just a cap that has exploded and that it hasn't destroyed a complete PCB. I expect I will be starting a new thread if it looks bad.
