ProtoDAC TDA1387 X8 project

[smokey_mountain]

Thank you, I have connected the newly built DAC today but obviously I made a mistake somewhere. I checked the 40-pin header for shorts as instructed, checked soldering everywhere all looks solid (only one of the Vishay may have less than ideal soldering but I do not want to resolder to avoid frying the Vishay) but seems ok under 10x magnifier. I used heatsink clips on Vishays.
Where do I begin to look to troubleshoot? I know it is a simple DAC but obviously not for me :
