    Hi Chris Haha yes the speaker cabels and the plugs are a common problem when they get older and pick up corosion and dust, maybe you buy some new ones or new plugs. The issue with the power PCB is quiet normal as the tuner board is drawing a lot of current from the power board for the signal LED's and the tuning center lightbulbs and other stuff. Can you imagine how hot the cooling fins get, can you still touch them with tuner on? They get really hot, but If you can touch them for more than 30

  • Re: beocenter 9500 issue

    Hi Rasto Seems that the mod board had no function at all, the errors and issues are the same when I read right. That's the first good step. I've had a Beocenter 9000 with strange behavior like flashing LED's when switching between the "SOUND" modi, FM station were not stored and maybe some other strange stuff. For me helped a "DELETE RAM" like it is written in the service manual: "TESTMODE" > KEY 7 > DISPLAY SAYS 1 > switch to STBY Good luck Christian

    Hi CHris 1. As I look to the service manual the volume lamps are parallel at 6,5 Volt so the limiting resistor for your LED's seems a liitle bit too low (about 60mA with 100 Ohm) 300 Ohm should work too regarding to you LED's current. If you are not sure that these LED's have impact to your powersuply voltages just disconnect them and measure the voltages and let us know. 2. The "A" and "B" at the power transistors gives information about the max B-C ( C-E) Voltage

  • BEOLAB 1 Powerlink issue

    Hi all I have a problem with a Beolab 1 poweramp module. When connected to Powerlink the unit switches on for a short and switches off after about 2 seconds with clear red and green light. About 7 Volt comming in from a connected Beocenter 9500 at PIN 4 of the Powerlink plug, tested a full Powerlink cable and a older one same effect. Switched to RCA input the unit switches on when short tipped to the RCA plug with a screwdriver and stays on. When signal is connected to RCA the unit shuts off aggain

  • Re: BeoLab 6000 switches on when placing frontcover - Why?

    Sorry but I don´t have further information to the modification. I read it somewhere long time ago and could´nt find it.back. Desoldering (removing) IC 1 means that you dont´t have the autostart funktion via RCA anymore. Kind regards Christian

    Seems that you are connected to RCA right? As I remember there was a workaround for that kind of speaker depending on the serial number. Two parts have to be soldered into the main PCB ( one diode and one resistor i think) If the speaker is set to RCA input a little 50 Hz hum or another distubing noise, prehaps catched from your frontcover, could trigger the power on. If it´s set to Powerlink (L or R) the speaker should stay off, if no Beomaster or Beocenter is connected or if a connected device

  • Re: beocenter 9500 issue

    Hi Rasto Maybe there are two possibilities to get the tape back to work. 1. Cut off the additional PCB from it's wires and leave a little pice of the isolation so that you can solder it back to the connetion points if nessecary. Look into the service manual for points where traces maybe have been cut. Look for the 4 big resistors and solder back to original values. It's quiet a lot of work and you have to be experianced reading the schematic. 2. Feel free to ask member dillen (martin at https

    Just downlod the requiered servicemanual, there you'll find the information you need. Follow the soldered wires if there are some traces cut, vias removed or other aditional parts like the capacitator on the backside. I don't have a photo at the moment but maybe there is someone else who can help wit a picture of the area where the modification is made. Best regards Christian

    one more suggestion maybe it could be a control PCB from another Beocenter 8500 or 9000 wich was modified to run with the tapemechanism of the Beocenter 9500. I haven't looked if there are differences on these board because there are not a lot of pictures to find with a detailed soluttion. Here is a picture of a offered Beocenter 9500 tape control board which has some different plugs and sockets and I'm missing the 4 big resistors and the plug with the thin white or grey wires normaly going
