Any B&O techies in Auckland New Zealand. I'm struggling with Beosound 9000
in Imported Content (Unmapped) · Sept 21, 2018 01:51Can't help with the reassembly sorry, but that pin and spring hinge assembly doesn't need to come apart for service. It is very likely that the laser pickup is the problem with no CD playback, they do fail. There used to…
BM3000 for something to do
in Imported Content (Unmapped) · May 24, 2018 22:08Never had an issue with this method in 20+ years.. its a bit of a time saver. A drop or two of freeze is enough usually, but the important thing is to apply and wait.. it can take 10 to 20 seconds to cool the junction in…
BM3000 for something to do
in Imported Content (Unmapped) · May 20, 2018 22:22Hi Craig. Rustling / crackling sound from a bad transistor or diode junction may be localised using electronic freeze spray on each suspect component, without the extra work of swapping components from channel to channel…
Wanted: Parts for Beogram 4002 type 5501
in Imported Content (Unmapped) · May 10, 2017 02:07Also, I noticed the cover for the lamp is missing, so I will have to source this part or fabricate something to suit. I suspect a high wattage lamp was fitted and caused the damage to the optical interrupter and lamp hou…
Wanted: Parts for Beogram 4002 type 5501
in Imported Content (Unmapped) · May 10, 2017 02:03Yes, of course. Here are pictures of the two items. The photocoupler lamp arrangement is how it arrived on my workbench, and will be changed back to original. I discovered the spring for the microswitch in the bottom of …
Wanted: Parts for Beogram 4002 type 5501
in Imported Content (Unmapped) · May 9, 2017 04:28Hi all. I am repairing a beogram 4002 on behalf of a friend. The clear plastic optical "ruler" with the sense lines is broken and is missing the end piece. Also one of the mechanical leaf switches underneath (the inner l…
Beomaster 6500 - strange behaviour....

Beomaster 6500 - strange behaviour....
in Imported Content (Unmapped) · Nov 10, 2016 06:02Check the backup battery if you have not already done so. If you have replaced it, then the unit may be in option 0 due to loss of nvram settings. Set option to 1 to reenable remote, then follow the procedure in service …
Beosound Century remote
in Imported Content (Unmapped) · Sept 22, 2015 21:49No picture, but it's under the right hand speaker cover, a small board mounted vertically (if century laying on it's back) with a square black photodiode on the front.

Beogram 4002, Type 5513 RCA to DIN conversion.. BEWARE!
in Imported Content (Unmapped) · Oct 2, 2014 03:03I just used your nice detailed post to replace a DIN plug on my 4002. Worked like a charm - thanks!
Beosound 9000 DEAD and I mean DEAD

Beocenter 9300 - remote control problem
in Imported Content (Unmapped) · Aug 21, 2013 23:34Definitely try a replacement photodiode if recap and cleaning does not fix the problem, however make sure that it is a close or identical replacement. The capacitance of the photo diode affect the tuning of the IR front …
Beocenter 9300 - remote control problem
in Imported Content (Unmapped) · Aug 21, 2013 23:31The receiver does not do any decoding of the data per se. It demodulates the signal removing the 455kHz carrier and sends the received data out the output pin, just like the integrated receiver packages do. The IR is als…
Beomaster 2400-2 input selection fault, symptoms include shut down or randomly changes inputs
in Imported Content (Unmapped) · Aug 21, 2013 22:54Hi Martin! This Beomaster was very clean and original internally with no evidence of water damage to the rest of the board. A similar type of failure can occur with small signal plastic packaged transistors. The metal mi…
Beocenter 9300 - remote control problem
in Imported Content (Unmapped) · Aug 21, 2013 00:52It is a good idea to take a cotton swab dipped in isopropyl alcohol and clean the board thoroughly. Those leaky caps usually leave electrolyte on the board which will be a problem. Don't be afraid to get the board really…
Beomaster 2400-2 input selection fault, symptoms include shut down or randomly changes inputs
in Imported Content (Unmapped) · Aug 21, 2013 00:34I have just finished this repair and thought I would share my findings. Symptoms of the failure include random shutdown, random changes to preset and input selection. In this case the fault was caused by corrosion and el…
Beocenter 9300 - remote control problem
in Imported Content (Unmapped) · Jul 26, 2013 01:22What is that black discolouration by the silver capacitor? Is it leaking?
