I have a lcd display running of a Rasberry pi and then going to a TFP401 HDMI/DVI Decoder then to a break out board then to the round display. The backlight turns on and i am getting data from the RGB bus (As far as i can hell by hooking up a scope to it and the signal changes as a change from the GUI to the terminal). But there is no image displaying on the display. What i am thinking is that the chip is not getting initialized correctly and was wondering how to get the chip to initialize.
Provided are data sheets to the TFP401 HDMI/DVI Decoder and the round lcd display
Anything is of help

My crystal ball is not working very well today.
You will have to give a few more clues if you really want anyone to help you.
Post a diagram of how you have everything connected.
Post a commented copy of the software you are using on the Raspberry Pi.
Post a detailed description of what the software is supposed to do.

Keith

From the information you have given me so far, the problem could be cause by:
A bad connection
A wrong connection
A number of wrong connections
A broken wire
A bad display
A bad Raspberry PI
Corrupt operating system
Missing software drivers
Faulty software
Missing software
Incompatible devices
I could probably suggest a dozen more possibilities if I had the time.

The ball is now in your court.
