Update on TN50X81 Toshiba convergence tripping shutdown.
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. Cheers, Wizard |
