B&O Beosound 8 - No go.

(1/2) > >>

Turnip:
Hi folks,

Have one of these Ipod docks which doesn't function - Checked the Power board and the always 5v is present, but it doesn't switch on and there are no LEDs lit.

Checked the main side of the PS and primary voltages are present but nothing from the chopper TX and the secondary dual diode is OK.

Any thoughts ? - Thanks - Chris.

Keith:
Hi Chris,

As with TVs data corruption can cause this! If you can find it, check that the oscillator is running on the micro, I've had dry joints on SMD crystals in similar equipment.

Thank Keith,

The logic board is stuffed full of chips - Well it's a B&0 who never go for simplicity, ever.

Only mentioned as this bit of gear was expensive, good sound though, folks say.

Guess a Quuq chap may well  come up with a shematic - Hoping.

Hate B&O, always have, but admit made a pound from their '70s TV sets where made cash from the dry joints they sprinkled about - Chris.

Hi Chris,

Bit of a secretive lot, this B&O mob. Maybe they should rebrand them KKK. Haven't been able to get my hands on a service manual. You're on your Pat Malone.                    Bruce

Keith:
Unfortunately Bruce is right, no schematics available. Best to return it to B & O for repair, saves pulling out hair!
