ADV7511W config problem

Hello,

 

I tried several ways to configure ADV7511W to produce some output on my sync, but without success. Here is my register configuration, I will be very thankful if someone can point me to ommissions I did during configuration. My video generator based on www.analog.com/media/en/technical-documentation/application-notes/AN-1270.pdf document is producing output of 720p, DATACK  is 73.529 MHz, HSYNC is 44.64MHz, DE is also as HSYNC.

 

Configuration is as follows:

 

72 01 00 ; Set N Value(6144)
72 02 18 ; Set N Value(6144)
72 03 00 ; Set N Value(6144)
72 15 00 ; Input 444 (RGB or YCrCb) with Separate Syncs, 44.1kHz fs
72 16 60 ; Output format 444, 36-bit input
72 18 46 ; CSC disabled
72 40 80 ; General Control packet enable
72 41 10 ; Power down control
72 48 08 ; Data right justified
72 49 00 ; No truncation
72 4C 00 ; 12 bit Output
72 55 40 ; Set YCrCb 444 in AVinfo Frame
72 56 08 ; Set active format Aspect
72 96 20 ; HPD Interrupt clear
72 98 03 ; ADI Recommended Write
72 99 02 ; ADI Recommended Write
72 9C 30 ; PLL Filter R1 Value
72 9D 61 ; Set clock divide
72 A2 A4 ; ADI Recommended Write
72 A3 A4 ; ADI Recommended Write
72 A5 04 ; ADI Recommended Write
72 AB 40 ; ADI Recommended Write
72 AF 16 ; Set HDMI Mode
72 BA 60 ; No clock delay
72 D1 FF ; ADI Recommended Write
72 DE D8 ; ADI Recommended Write
72 E4 60 ; VCO_Swing_Reference_Voltage
72 FA 7D ; Nbr of times to search for good phase

 

What I need is to output black or any other static color image, as video is irrelevant in this application.
