one of the buttons on the controller does auto config when you press it. Can't remember which button. Try that when you get the distorted signal.
also, what resolution and refresh rate is the output on the computer set to? it might be too high resolution for the controller/display or too high refresh rate...

Also I made sure the resolution and refresh rate output of the vga is 1280x800 @ 60Hz. I also played a little with them a little, set some lower resolutions and frequencies but still the result was distorted. Plus the auto config button does not solve the problem.

It's really weird. If I don't plug any input in, everything's fine!
Any clues?

Since it seems to work when there is no video input signal, I guess the output side is fine. Must be something on the input side then.
Your display panel has a resolution of 1280x768 (WXGA). If you feed it with 1280x800, that might cause problems. Maybe start with the basics, like 640x480 or 800x600 @60Hz if you haven't tried that already.
What is the video source you are using? A PC?
Not quite sure what else it could be. Might be a good idea to contact the seller and see if they have heard of that problem before.

As for the resolution, I'm quite sure the diplay resolution I had on my laptop (while it was still working) was 1280x800 @ 60Hz.. But I've also tried setting smaller ones like 800x600 and 640x480 and none of them worked. The only change I see, is that when I change it, the distorted schemes get larger on a smaller resolutions.
Also, something else worth mentioning is the following:
1. I turn on the LCD and browse to the VGA input channel. It shows no signal correctly.
2. I plug in the vga cable from my pc. (I've already set the resolution and frequency for the second monitor on windows, also set it as extended desktop).
3. The image gets distorted. It actually shows my windows desktop in a distorted way. I can figure out the colors, that identify that.
4. I unplug the vga cable from the input.
5. Now the LCD shows the No Signal box but it's still destorted!
6. If I browse through the input channels on the controller they are all distorted until I switch back to the vga channel which is now clean. -OR- if I turn off the controller and turn it back on it gets clean again.
Now what could that mean? Could there be something wrong with the controller or the LCD?
I remember the LCD worked fine until the laptop died.

Hmmm... not sure.... Since it also happens with the other input methods, I'm beginning to suspect the controller. I would contact the seller. I've bought from them before and they usually respond quickly.
