I have a problem with a Beolink 7000 not transmitting IR. After exchanging cards in the Beolink I found that the fault is on the CPU board. The service manual for Beolink 7000 is, sorry to say, not usefull since there are no diagrams in it.

Does someone have a full service schema for the Beolink 7000?

Check the lithium cell for leaking... probably the acid has destroyed some of the copper lines of the cpu board. Typical for not transmitting data.

There is no diagram available.

Thanks! You where right, one copper line was (but not visibly) broken under the battery. Kind of self distructing construction..
