I forgot in my hardware design to pull down the TEST1 & TEST2 pins. Are there internal weak pull downs realized, or do I have to make a design re-spin?
Test pins are do not connect pins. The ADV part will work regardless of advices from both manuals.
If you cannot guarantee accidental contact to the test pins, hence the advice in HW manual.
We are checking with part specialist on this question now and we will update you soon.
thanks in advance.

According to the ADV7604 data sheet, it is recommended not to connect to those pins. I am not sure why you want to do otherwise.
by the HW manual, table 1 Test1/2 Pins have to connect to ground via a 10k resistor. In the current design it is'nt, so the question was, will the ADV still work as expected, because of any internal measure like weak pull-downs, or do I have to make a design re-spin for bringing up the prototype?
