BEOCENTRE 3300 wont power up

8 replies

I just rescued a 3300   but it doesnt power up.  I knew it wasnt working but wondered if it could be something simple and maybe needs a simple part -  fuse maybe? 

 

So two questions

 

How do I work out whats wrong?

Where do I buy parts   I live in France but happy to buy off the net

 

Thanks for anyhelp

Welcome to Beoworld !

How are your electronic skills, tools etc. ?

Thank you Martin  its nice to be here.

 

My own skills arent great  I used to build my own cars and do their electrical systems but  I have 2 friends to call on - 1 a qualified domestic electrician the other works on the electrics of the french high speed TGV trains

 

My own interest is  the design aspect in B&0    the 3300 is sitting on an early 1970s Danish sideboard   if I can get it working its a bonus

Replace the capacitors on the power supply board as the first thing.

All of them, also the two big ones placed away from the boards?

I am having the same problem - no power - and was wondering where to start.

Thanks in advance.

Primarily the ones on the board.
Check also that the power switch is functioning correctly. If it doesn't release completely
it won't power up. Tighten the spring on the switch.

Thanks martin. I have started a new thread with the project and some details from my measuring. 

I actually forgot about this question, but I will try the two steps! and upgrade my membership.

Beocenter 3300 (as in this thread) or Beomaster 3300 (as in the other) ?
They are completely different machines.
