Hi,  i get 1 sapre BM6000 unfortunately appear to be faulty , well its turning on for a 1-2 sec then going off with little tick like sound, however it stays on for about 10 minuts when i put it straight away into clock mode 

any ideas what could be wrong with it ?

Hi,

My guess is bad quiescent current because of bad trimmers in the amp section...

The usual!

Is the BeoMaster getting hot before it is switching off? In that case it could indeed be the potentiometers in the amp section!

i dont think its getting hot as he turn off after 2 sec of turning on , and stays in standby mode ... is it easy to fix ? 

It is an easy fix—I just did mine—provided you know a few basic notions about electronics.

The Beomaster 6000 is easy to open and access to modules is easy as well. You shouldn't have any problems finding the necessary service manual which by the way is available on this site to gold members which I'm now proudly one!

Do you know what a quiescent (idle) current is? Can you identify the different components?

If so, we can help, and you'll find here the right people for the job!

to be honest im not really into fixing electornics by myself , however if i get proper instructions i can do almost everything :p or it might be just better to let somebody else to fix it ?:)
