MMh,

i exchanged now also the third transistor on the PCB3, changed also another blue capacitor and checked the sockets. I resoldered some, but they looked good .

no change.

The player starts and then stops after about 10 seconds.

What makes me nuts – it needs to be on this PCB as with another one the player worked well.

What else could it be?

best regards

Thanks Derek,

i will try. Please cross fingrs. The item itself really looks nice and everything worked well.

Just need to fix my ouverture on the table, where ic hhave issues with the tape deck(s). Have one, where turn doesn´t work, one where it only spins in one direction (even if fast forward runs in both) and one where turn leads to an immediat stop of all wheels.

Hi Steve,

thank You very much for your help. Much appreciated.

Best regards (from a youtube follower – i learnt so much from your videos)

You should take the 1mm thick one, it´s better. the thinner let you see the glueing tapes.

Now, with the 1mm part, it looks like new. Strange. Somehow to new 🙂

Found something in a store for students of architecture. It´s 0.5mm PVC. Looks exactly like the original.

Hi quatttro,

where is the relay in a Beogram cd?

I checked the secondary keyboard several times (as i had the issue of not sitting correctly with another BS9000). Bu – no – it wasn´t that.

Now i am somehow guessing (after trying to understand the circuit) that the IC14 on PCB32 (74HC138) could be a candidate. I ordered one and will try to exchange that one. Somehow everything around keyboard one and two goes through that IC.

Am i totally wrong?

 

Best regards+

Hi Mark-fs,

thank You for the hint – i will do so.

What i am wondering, that both (the cd allocaton buttons plus the door opener button) and the main keyboard are not working. Arent these two seperate cables, or do they connect to the same IC and PCB?

Best regards

@Mark-fs: what does put a scope mean?

@Beobuddy: which IC should I look first?

 

i don’t have an oscilloscope.

 

thank you all for your help

Am I really the only one who has/had this issue?

So, I dismantled close to everything. What a mess.

followed the cable from the lid opening and cd buttons to the respective pcb.

attached and loosened it all several times.

assembled everything together and …

 

 

 

 

 

 

 

 

… nothing. No change. This beosound currently just wants to be controlled remotely.

 

Doesn’t want to be touched directly ?

 

i think now, I need a replacement pcb, just don’t know which one.

 

i think I checked all TMs

 

best regards

Really curious – never saw this behavior before.

i could live without the keyboard, but always opening the lid by hand (against the spring) doesn’t make fun.

 

what I also don’t understand. Why both sides don’t work, assuming they are not connected via one cable

Update

 

you need to put the glass on.

now tm71 runs through and states ok.

i can now play radio and cds with the remote.

 

buttons still dead

Hi Bill,

thank You for your hint.

unfortunately it isn’t that easy. I was hoping for a quick win.
i checked mentioned cables and now I am one step worse.

still no button response and now

only radio is working.

Tm27 does show the slc err, but in tm71 the whole unit shuts down after opening and closing the door.

Before my opening, tm71 was running quite good. what did I made wrong?

best regards

i found the error – see my other post

[69er]

Its still not winding as it should – any idea here?

[69er]

And now it works again

 

 

i am getting mad

[69er]

It’s totally weird.

now sometimes it works sometimes not.

after rewinding 5 times in both directions I reassembled the whole thing together and now it doesn’t rewind again (with housing).

????

 

[69er]

Is there still one piece available – i would like to built one beolink 5000 (mine doesn´t show anything on the screen, but works).

Best regards
