Beocord 2000

11th November 2008

No sound and the level meter showing some segments lit all the time is a common problem with this model. The cause is lack of the 7.5V bias supply which comes from the LM1131C Dolby processor IC. The chip itself is rarely at fault however, the culprit is most commonly one of the two 220uF electrolytic capacitors C208 and C408, they tend to go short circuit. Fortunately the chip usually survives this. The Beocord 3300, 3500 and 4500 use a similar circuit (but with only one capacitor) and so can also suffer with the same complaint. [Beocord 2000]
