Hi.
This is my first post so please let me know if i hit the wrong forum.
I am currently repairing a DVD1 4621 SerNo 19294699 ItemNo 1462008
The power supply is bad, only 5V standby is working.
i located a defective reference voltage generator (?) - no reference is passed to the oscillator.
Is there any schematic available ?
Regards
Mark

Mark,
Most of the DVD1 was not designed by B&O and the Service Manual which is available is just a repair manual for changing faulty modules.
Below is an overview of the wiring from the power supply only..

Hi Keith.
I have the "Service Manual" - and yes, B&O kept us short.
Does anyone have a schematic or knows who actually designed the PS ?
Hi Mark!
To my knowledge there where two generation of DVD1. Mk I was based on a Philips mecanism and Mk II was based on a Pioneer mecanism. The type number ob your DVD1 (4621) points to a MkII/Pioneer based model, but I have no idea at all which specific Pioneer mecanism was used.
I hopt this helps.
Cheers
