Beocenter 7007 Tonearm Resets

[Nebojsa Jankovic]

Hello, after a month ot two in standby, I just wanted to play a record on my BC7007. Started it, tonearm lifted, went to the beginning of the record, landed, played for 2 sec, then liftrd and went back to the park position. Tried several times, powered the system down, with no change! Now the arm resets within a second of landing down on the record, every time. Please advise if this is a known failure mode and how to remedy it! Thanks in advance for any HELP!

An update from myself. As I wanted to test another set of speakers on my Beocenter 7007, I used the radio as a sound signal and found out that the system shuts itself down after about 20-25 seconds. Turned back to the turntable and it played the LP (Steely Dan Live) properly for about 25 secs and again system shut itself down! So, this leads me to believe that this symptom has to do with the power supply and/or supply circuit itself. Any ideas, please?

Check the idle current settings.
Check for DC on speaker outputs.

Thanks Martin! Will get on with it, as I also accidentally noticed that one of the “Speaker 1” outputs does not work, as I have always used “Speaker 2” channels…

Hello Martin, if I may ask, in order to reach the solder side on the main board of the BC7007, do all of the components, that are now on top of it, need to come out before the board itself would be removed or is there a way to get to its solder side by removing the bottom pannel of the beocenter?

Thanks in advance for any help!

Kind regards, Nebojsa
