Subject: Dead BBC B

I have a dead BBC B here, which used to work.... not too long ago.

It's an Issue 7, fitted with a disc interface (8271), no econet or voice 
chips.
IC51 is ...PB04, IC %@ is ...PB05 IC88 is a DFS EPROM (2764).
Links are: S20 North, S21 both East/west, S22 North, S25 north, S26 West, 
S31 East, S32 West, S33 West.

The Beeb powers up and hums, but no BEEP. No video.
Power supply voltages all good, Shift Lock LED is on. All dip switches 
beside the KBD are east.

Any clues?
