toto3, I just tried it at 5V and the color looks exactly the same.

I guess that is not your problem. I will post my exact pinout a little later so you can compare.

Could it possibly be your backlight inverter?

r0 to r2
r1 to r3
r2 to r4
r3 to r5...

The theory is right. You should use the most significate bits first. That may fix you're whites being yellow, etc...

I also have that screen. I'm not using it because it is a 12-bit screen (as mentioned by infrared earlier). Being 12-bit there is a total of 4096 different colours that can be displayed. The 12-bits have to be divided evenly bewtween red, green and blue given 4-bits of diversity in each colour. So each colour has 16 different possbilities (or shades). To get any decent picture on a DVD I would think that at least a 16-bit screen would be needed.

Sorry to be the bringer of bad news...

littlej,
I appreciate your response. It gives me confidence to try rewiring the cable.

I'm not to concerned about DVD picture looking great or perfect. Just want it to look decent or acceptable. What I've seen so far is OK. Heck it's going in my car. It's not a theater system.

Plus how often will I be watching DVD movies in my car anyway. It's mainly just to say I did it and for relatively cheap.

I'll keep everyone posted.

Thanks,
pigseye

Pigseye,

For $25.00 + shipping I can sell you the MicroTouch serial cable. It even has a dc input jack for power if you need.

I had to order a couple for a minimum order.

I'm a taker...you've got mail.
