edit: Basically all working. Couldn't figure out how to route audio through the 34 pin connector but that's OK.
Hi guys. I have a Sony KV25xBR. Currently I'm testing the RGB input by connecting some 20awg standed wire to the socket on a Genesis 2. I'm able to produce a horribly-colored image like this:
which looks to me like it's treating the signal as a digital RGB signal.
I tied the Mode Switch pin (21) to +5V and got the same picture.
My connector has the following connections made:
pins 34, 21 and 1 joined (audio select and Mode switch tied to +5V)
Pin 30 to Sync wire (Sync)
Pin 27 to Blue wire (Blue)
Pin 26 to Green wire (Green)
Pin 25 to Red wire (Red)
Pins 3, 7, 8, 9, 10, 13 joined to each other + Ground wire (audio R gnd, audio L gnd, Red gnd, Green gnd, Blue gnd, Sync gnd)
So to detail what I've tried, I tied 21 to +5V but that didn't make a difference in picture. I found an old writeup on interfacing an Atari ST to this monitor, where it said to join pin 29 (Blanking input) to +5V, that sounded wrong but I tried it anyway, and it didn't make a difference (I undid it right afterwards). Curiously, if I insert the Sync wire into Composite out, I get a very washed out full-color image. Playable but very ugly looking.
Here's a picture of it with composite as sync:
So the missing link is to take the monitor from thinking it's treating the signal as digital RGB and make it think it's analog... I'm looking at Google searches like crazy, but I'm not finding much about this.
Thanks for any help![Smilie :) :)](/ubb/smile.gif)
edit: I've done some more poking around, I've tied 33 (RGB/Normal select) to +5V, no change. I tied 21 and 33 both to +5V, no change. I tried each separately and together tied to ground, no change.
