With datasheet for PCM56P DAC ICs, I see why I'm not getting all the
signals, some partials, some totally off and some are flatlined, only
two out of six were outputting correct signals for convergence amp
ICs. All six of DAC ICs are getting data, clock and enable signals
from T7K64 IC with own EEPROM.

Do I go with replacing PCM56P DACs or this T7K64 IC (SMD square IC)?

Do anybody else see high failure rate on PCM56P ICs it is DAC by
burroughs brown.
