hi martin! thanks for your support! i´ll check B&O, if they still have the processor. have a nice evening! jens

hi nic! the two voltages on the transformer should be 10VAC and 20VAC according to the repairmanual. after the rectifier it should be 10.5VDC at c1 and 24VDC at c10. after a regulation circuit the 10.5V go down to 6.5V (plug p41 position 1) and the 24V go down to 15V (plug 42 position 5 and 6). i suppose, you´ve checked the fuses on pcb 11 (the

hi martin! i guess the ic is no longer available? it´s a shame, that after all the work and the new parts, i have to give up. thanks for your help! jens

i double checked the zener, it´s a 2V8 zener bzx. but when i put the old one (the original b&o) back in - surprise,surprise all the voltages went back to their former values. so i´ve got 2,9V over D6 and 4,6V on ic pin 39. but unfortunatly still no reset and no standby.

hi martin! as far as i can see, the power supply should be o.k. i had 4,6V at pin 39, then i replaced d6, now i have 0,1V at pin 39. voltage at d6 is 4,9 V, which is obviously too much. so i will check around the reset circuit. i already replaced tr5 and tr6, but nothing changed. thanks for your help! greetings from munich! jens p.s.: my beogram 6006

hi! i bought a faulty bm6000 quite a while ago over ebay, and gave it a secod try now for bringing it back to life. it seems the microcomputer got stuck and doesn´t reset. so the reciever doesn´t go to stand by, but shows weired info on the display; after 2 or 3 seconds the amplifier protection circuit is activated and the display changes

my first guess for a piece, that hasn´t been used for 15 years, would always be dried out capacitors.... the beomaster has two big ones in for decoupling the speakers, perhaps the problem originates here? good luck! jens

puncher is of course absolutly right. 39R means resistor with 39ohm 3R9 would mean 3,9ohm 39K would mean 39000ohm 3K9 would mean 3900ohm and so on jens

hallo martin! das bild sieht eigentlich sehr gut aus...und bei einer ersten sichtprüfung waren auch die kondensatoren noch ohne heftige mängel - soweit man das halt sieht. aber ich werde die bei gelegenheit mal austauschen. aber: das mit dem store - picture bzw sound - store war dann doch ein guter tip..... peinlich, peinlich, aber ich hab

hi! yes the battery charges - i measured the old one, which i replaced, it has 2.5 volts. there was a little sticker on the old battery, which said, it has 2.4 volts and a capacity of 180 mAh. my first thought was in the direction of a bad capacitor, perhaps around the resetcircuit of the microcomputer... unfortunatly i haven´t got any service
