So I'd like to hook up my dreamcast to my new 30hs420, but there is no vga input to do so.
I've been looking at the schematic for the HS series, looking for places where the RGBHV signal could be swapped in, bypassing another input.
For example, if you look at the signal flow block diagram for the HS, you will see that the HDMI sends either YCbCr or RGBHV to the cxa2171 chip. I was thinking that would be a good place to solder in the RGBHV from a VGA plug, but now I think that the chip probably looking for digital RGB and wouldn't work.
But throughout the rest of the schematic, I'm seeing many places that are labled Rin, Gin, Bin and so on.
So my question is, if I find the right place in the signal path on one of the PCB's, is it possible to add a vga/rgbhv signal that will be properly displayed by the TV?
Or hell, there might even be a spot on the board where they have an RGBHV input but didn't actually wire it to the back of the TV for some reason. Anybody know anything that could lead me in the right direction?
