It might be bad soldering contacts of the connector from the powersupply to the mainboard. They could cause this kind of problem!

Wat ook nog wel eens wil gebeuren is dat de contacten in de ML-aansluiting in de Ouverture of in de BeoVision iets willen verbuigen, waardoor er zich gekke dingen gaan voordoen. Je kan dit zelf bekijken als de ML-stekker er uit is. Kijk dan achter in de aansluiting in de Ouverture en de TV. Je ziet dan de contacten van de ML-connector. Deze moeten netjes

You can try to disconnect the mains from the BeoSound 9000 to reset it, disconnect the ML from the BeoSound 9000, connect the mains again to the BeoSound 9000 and see what happens.

If you want a difference, use a mains filter. I have seen the difference on an LCD screen with and without external mains filter. After that we tried the same mains filter on an Avant. Then we could not notice a difference. So something like a mains filter can make a difference, but not if the mains filtering in your equipment is allready good!

Welkom op BeoWorld! Heb je het probleem ook als je een hoofdtelefoon aansluit op de Ouverture? En heb je misschien een linksysteem? Zo ja, heb je het probleem daar ook bij audiobronnen?

Glad to be of help!. Have a lot of fun with your BeoCenter 1!

In that case you have to choose the MENU via the display under the picturetube. So press DISPLAY on your Beo1 (or MENU on your Beo4). Now the red display under your picyure tube will show a source. Now keep pressing << or >> on your Beo1 or Beo4 untill the display shows MENU and press GO after that. Now you are in the menu!

I use a simple hobby glue, works like a charm (Bison Hobby glue, sold here in the Netherlands). Make sure there are no solvents in the glue, they will dissolve the foam!

What is the typenumber of the BeoCenter 1?

The Always On problem is is probably TR3 on PCB2 (front PCB) which is leaking, BC337-40. Also a common problem. After replacement I am almost 100% sure the problem is solved.
