my beomaster 5000 has an annoying habit of switching itself off. sometimes after just a few seconds, other times it can run for half hour or more. mostly does it on tp 1 tp2 and aux settings, but not very often on tuner. anyone had similar problems?.

Sure, replace the idle current trimmers and readjust to factory spec.

Do one channel at a time. Start with the one having the highest idle current since this is the one that causes the problem and if not done first it will shut down the Beomaster while you try to adjust the other one.

many thanks, not too technically minded though, whats an idle current trimmer? where are they? and how can i go about replacing them. sorry for sounding like a complete dimbo....alex

It really is a job for a trained electronics guys with the components in the drawer and the tools and instruments on the bench. If everything else is fine it's a one hour job so shouldn't be a costly repair.

many thanks, i think i know a man that can.
