  • Re: Beomaster 5500 not always starts into standby

    Hello Martin, thanks for the tip with the power supply. I replaced C1 and C10 on the processor board, but no change. Measuring shows 5V and other voltages were also correct. Then I decided to temporary replace the 4700uF in the power supply with 3x2200uF cheap capacitors (I have only those 3 at the moment). And ? The machine starts much better, after

  • Beomaster 5500 not always starts into standby - SOLVED?!

    Hello Bang and Olufsen friends, after a break due to the two business trips to China, I started repairing my Beomaster 5500 (I already managed to repair the Beogram CD5500 with the powerfull help from this forum->thanks again). The problem with my Beomaster is, that it will not start into standby when the power plug is connected. Nothing is displayed

  • Re: Beogram CD 5500 - no sound, noise only - SUCCESS

    Hello, I checked all other caps and changed power supply to 240V. Thanks for the tip. Now the CD player works SUPER !!! It reads all CDs and CDRs without problems. The sound is really good. Now it is time to reactivate dead Beomaster 5500. No signs of life, I discovered the short circuited capacitor on the radio board. This damaged the Zener diode that

    Hello, I successfully repaired my CD5500. Thanks a lot for the help ! What I did? First I checked the ICs (IC2, IC2 and IC3) for the power supply->all voltage OK. Then the power of opamps IC11 and IC12. At pin 4 the voltage was 13,9V (OK) but at pin 8 there were some millivolts. Check at capacitor C102 and C202 showed, that both had short circuit

    Thank you for quick response. Yes I have SM, but unfortunately no oscilloscope (still beginner...). I will check the 5 V supply and the power of the opamps as you stated. Maybe I can discover something. Regards satmonster321

  • Beogram CD 5500 - no sound, noise only - SUCCESS

    Hallo, first I want to thanks all the people in the forum, who writes interesting tips regarding repair of the B&O stuff. I bought my first equipment one year ago (Beogram CD6500) and was able to repair it (servo capacitors) after researching in this forum Now I own the second one, the Beogram CD5500. It had the same problems with finding the CD
